FF12 Front Firing Subwoofer

Éste subwoofer genera graves bastante contundentes considerando su pequeño tamaño, es excelente para sistemas muy sencillos como lo es mi caso, agrega muy buenos grabes para ver series y películas, para música hace que tenga buena respuesta en el rango de las frecuencias grabes pero si quieres mayor impacto en rangos bajos adquiere uno de mayor tamaño, posiblemente de 10" sea una excelente opción

Si no tienes espacio es un buen producto, es compacto y tiene buen sonido, si necesitas algo de potencia no lo recomiendo sus 150w a lo mucho son 100w debido a que es clase ab. Con uno de estos y un par de monitores presonus o mackie obtienes mejor rendimiento que un logitwch z625 casi al mismo precio. si tu espacio es grande no lo recomiendo.

Good sounds and flexibility of connection

1st things first. You're only going to get out what you put into to drive this subwoofer. If you're inputting under 60 watts, expect your results to vary significantly. With that said I have this plugged into my Yamaha TSR-700 which is rated at 100 watts per channel. (See settings settings in the attached pic.) No need to crank it up to get very good frequency response. Testing with over air FM transmission delivered impressive tonal response. Direct connect HDMI devices or Streaming should excell. Will update review then. Controls The Filter, Volume, and Phase controls all work as they should. The filter feature really dials in response nicely. The Auto On/Off works very well. The speaker shuts off after 30mins of not receiving a signal. Some of these features aren't even included on bigger subs from more established brands. Note: Don't blow crazy money on RCA cables. I'm using tried and true quality cables I've owned for over 10 years.

There was a couple reviews that state "Couldn't hear hardly anything, had to turn bass volume and frequency all the way up barely hearing any bass." That couldn't be further from the truth! Let me explain why I think they said so. #1) If they are around my age then they most likely know and recognize the brand name (Earthquake) from there late teens and into there 20's being a car audio subwoofer that took insane amount of watts with one the most heavy huge magnet and basket for it's time and with the proper installation would set off car alarms, rattle mirrors to the ground and even blow out back windows. Well this isn't that and nor should it being a home audio subwoofer. It should never overtake the experience and sound of your main speakers should only complement the sound of your system allowing your speakers low end to not be worked so hard to achieve sound greatness. #2) Those other 2 reviews well how can I put this, in the words of a ex president "those 2 reviews are Fake News." Size to sound output it would compare to something like a little mouse 🐀 walking up to you and punching you in the face with the power of Mike Tyson. Buy this Sub and don't look back with any regrets and enjoy great bass at a afford price.

Read reviews and was worried wouldn’t shake the floor Bought the refurbished unit from Amazon and came in new condition Set it up and it was much much more than enough for a 10x12 office room. Very happy with product. I love hip hop and lofi and the bass is plenty

Maximum happiness with this little beast. If you need a home theatre sub, look no further. I like it better than the old Wharefedale sub it replaced!

I never owned a sub woofer and relied on the Fluance surround sound for depth. The addition of the Earthquake sub has really put the grunt into the system, particularly when watching movies. The 400wRMS delivers more than enough quality bottom end for my lounge room. I thought the price compared to better known brand names was a consideration and now its up and running, I am very happy with the purchase. Can recommend.

Comments here are for the Nova earthquake FF10 subwoofer. There isn't much content online about this product, but that does not mean it's not worth your $$! Decently priced 400 watt sub that delivers good performance. Base note output is punchy enough..great if you share a wall with your neighbours. Built in Fuse allows for easy importing as you can switch from Us voltages to Aus/Asia voltages (250watt max). Volume rocker on the front is a nice touch and build quality is very acceptable. Overall it was worth the "gamble" just wished there was more coverage on internet media so more people will take a chance on Earthquake audio products. In conclusion, if you are looking for a subwoofer that creates enough rumble to be FELT and heard, but are not interested in getting a overpowered earth shattering subwoofer with big price tag.... this is the sub for you.

I like it a lot, deep sound and 0 noise. Its a great product

I liked this for the most part but it only could hold a 12oz steak. In the future they should only be used for home audio

This Subwoofer sounds great, automatically turns on and off and has great flexibility.

premesso che cercavo per una seconda casa con stanza di piccole dimensioni, dotata di ampli stereo Yamaha 50+50 W (con pure direct), 2 subwoofer con attacchi ad alto livello sia input che output, non avendone l'uscita dedicata, che suonassero quelle frequenze che i woofer di 2 Indiana Line Tesi per il piccolo diametro non suoneranno mai pur senza distorcere. La mia scelta è caduta, dopo il fallimento di 2 Polk, sugli Earthquake. Essendomi necessari per la musica, dopo la negativa esperienza dei Polk e non fidandomi molto di 2 Mivoc prescelti, ho preferito mettere qualcosa in più di soldi, ma andare sul sicuro per ciò che particolarmente serviva a me, ovvero collegare il canale destro e sinistro dall'ampli ai sub e le IL agli stessi, Left e Right. Soddisfatto. Dopo 2 gg. di prove con tutti i miei file musicali e CD, dall'HM alla disco, alle colonne sonore anni '70, ho dovuto regolare il volume a metà e la frequenza di crossower dei sub a non più di 60 HZ: non distorcono mai, la qualità degli ampli dei sub è importante e, posizionati di fianco a ogni cassa Indiana Line ai lati del mio letto non si sovrappongono nel suono delle frequenze, ma il tutto è armonizzato come suonasse una sola cassa, a destra e a sinistra. Sub di ottima fattura e costruzione, pesanti, arrivano con i piedini in gomma antiscivolo già montati, perfetti, anche con i bassi più forti non si spostano di un millimetro a differenza dei Polk che ho dovuto restituire, assolutamente inadatti per la musica. Questi Earthquake hanno un limite solo nel suono particolare dei driver, ovvero non pieno, gonfio come la classica grancassa di batteria, bensì più 'rombato' e a corsa lunga, più tipico della sospensione pneumatica che del bass reflex, ma si armonizzano bene con lo stesso suono tendente al 'rombato', ovvero sul tipico dei 240 HZ, dei woofer IL, ma scendendo molto in basso senza distorcere. Tutto sommato, per ciò che serviva particolarmente a me, ovvero i driver frontali con relativa fuoriuscita d'aria anch'essa frontale che mi consentono di tenerli non molto distanti dal muro per le piccole dimensioni della camera con il mio letto in mezzo, vanno benissimo e non credo potrei aver trovato di meglio. Sento i suoni in mezzo alle orecchie con buona qualità come avessi una cuffia. Aggiungo, dopo mesi di utilizzo, una stella per la sua sensibilità in ascolto anche a bassissimo volume: si accende automaticamente senza il minimo rumore. Amazon precisa nella gestione dell'acquisto

Muy Bonito el subwoofer, el único detalle es que siento que le falta un poco más de potencia

Todo muy bien muy buen sonido potencia profundidad

Realmente estoy muy contento con la funcionalidad y potencia que tiene el Subwoofer F12 Activo de 12" Color Negro. Se escucha verdaderamente potente y de una excelente fidelidad. Estoy muy contento con su diseño y calidad.

Mucha potencia (300 watts) buena calidad de sonido va dirigido más a teatros. Lo malo es que tiene los controles al frente y el sistema para quitarle la tapa es con un listón. Estoy satisfecho con la relación precio producto. Debido a su gran potencia debes ajustarlo a lo que vas a escuchar y cómo lo quieres oír

Mated with Peachtree Audio M25 perfect sound!

delivered in a timely manner and works as designed

Setting up a small 5.1 system in a 10x10 office and this fit the bill. I originally started with the Monoprice 8248 8" sub which sounded much better than its $50 price tag suggested but it had issues with ground noise and an auto on function that would turn the sub on/off intermittently unless the volume was turned way up. I researched many compact subs and wanted something that could fit in a space at the bottom of a desk cart in order to keep it out of the way. The Monoprice was a tad big for that space and I had to locate it somewhere that wasn't ideal. When I saw this Earthquake was under 10" tall, which was perfect for said space, I decided to try it. I know Earthquake from their car audio products but never tried anything home audio from them. After initially hooking up the sub to see if it functioned, it barely made any noise when I played music from my iPhone. I had to turn the gain past halfway before it made noticeable sound. After positioning it in its permanent space, I ran the auto calibration on my AVR. It set the 2" Dayton satellites I'm using for LCR to 200hz which I felt was high but after listening to other x-over points, 200hz was indeed the best sounding. There is some localization using this x-over with male vocals, notably Sam Smith but after calibration and setting the gain, bass is very smooth and blends nicely with the satellites. Not boomy and adds a nice punch when watching movies. This won't knock your socks off but that's expected of any 6.5" driver and it certainly isn't my intent. Placement and room size will be key to its performance. Keep your expectations realistic and you will be happy. Build quality is nice, very solid cabinet and it uses a 3-prong plug unlike most budget subs this size. There is a ever so slight hum, might as well be silent and it might have more to do with the electrical wiring in the home than the sub, but it's definitely much more quiet than the Monoprice. I managed to snag an open box via Amazon for $110 and it is worth every penny. At its going rate of $200 new I would think twice as you are getting into the price range of bigger, better subs or close enough to a nice mid range 12” where you’re willing to pay the extra $ and say to hell with saving space!

Update - 08-01-2022: Bumped the rating back up to 4. TIP - Installed a ground-loop isolater (from a 12v system) and FINALLY I have good sound out of this little box. It's still not a full room-thumper, but now I can safely recommend this to others (if they don't mind a manual upgrade). Update - 8/11/2017: Some time with this sub has inspired me to drop my review down to 3 stars. Yes, the sub can accurately produce very low frequencies, but at spl that will require a very quiet room to appreciate. If you turn this thing up to the level where you might normally appreciate a subwoofer (e.g. tactile), you will be extremely dissatisfied with the audio quality. It starts chuffing and farting like it’s going out of style. After all, high excursion drivers are not notoriously accurate. Then the crossover just does not clip nearly enough. With the filter at the lowest setting (40Hz) I can still hear soooo much of my mids in this guy messing up my sound. I’ve tried it with different x-over settings, with different sources, at different room positions, and with a signal pre-amp – I just can’t get it to output any quality sound above ‘gentle’, and honestly I want more. Original Post: Went through the same trouble with the buzzing as other reviewers when I got this one. Somewhere between the first turn on, the multimeter measurements, and the last turn on the problem went away. Boy was it annoying though. The buzz seemed like a ground loop issue, but somehow it's resolved even though I'm using the same cables, placement, and electrical outlet. It was acutally sending noise from the output of the FF6.5 over to my lovey Audioengine A5 monitors. On to the sub performance. For the size of it, I think it does a nice job. I have not really taxed the output, but it's for an 11x14 room just to add low end to my A5's. Running it with the x-over set to 90Hz, and this seems to blend the best with my monitors. The auto on/off seems to work well, and it has a soft start/stop so no annoying pops or crackles. The sound is definitely more smooth and low rather than tight and detailed, so I can't say I'd recommend it for critical musical listening, but for jamming in your office or playing video games in a small room I think you will be very happy. It certainly does get into the low end, and I appreciate that very much. Most subs in this range will rapidly roll off at 50Hz, and this one holds on tight up until about 30, and becomes almost gone by around 24, but that's really good for a 6.5 sub at this price. My target was useful 20Hz at under $200. Yes, almost impossible, but I got really close here. I think I did well considering the price range, and that the speaker is worth it's price-tag (even if it came to me making funny noises). I'm not falling out of my chair in admiration, so 4 stars, but I am pleased with it and satisfied with the purchase. Can't say I've compared it to everything out there, but you probably won't get better low frequency sound with anything else in this price range. As for output, it's more than I need for my office so - huzzah.

Where do I begin? Let me start with the technology that is offered in this product... This Earthquake FF6.5 is pristine example of proper audio engineering, fine tuning and care in a finished product. Let's start with the enclosure; What you have in the 6.5" model is unlike any offering from other manufacturers out there. The enclosure is an extremely solid(resonance-free) quarter-wave transmission line/horn-loaded hybrid made from a combination of 3/4" and 1/2" MDF. Implementing this technology into a home theater offering is an incredibly wise thing to do. Why? The output and accuracy of low-frequency notes are greatly increased, making this subwoofer not only loud but INCREDIBLY efficient and accurate. Quarter-wave transmission line enclosures, if made correctly, can take a smaller driver(subwoofer) and make it equal in SPL to larger subwoofers with traditional ported or sealed box designs. What this means is if you wanted the true output level of a 10" subwoofer but would like to save some space without compromising anything, this is your sweet spot... This enclosure is built in such a way that the air pressure produced from the subwoofer acts as an efficient cooling setup for the amplifier. This allows the amplifier to be internally concealed as opposed to sticking out the rear end of the enclosure= more saved space! Second... The subwoofer itself. What you have here is a long-throw 6.5" subwoofer with patented Turbine-Cooled-Transducer technology. This technology forces air in through the holes on the bumped backplate, over the voice-coil and out again with each cycle. This allows the subwoofer to play at high levels for a long time while remaining cool, thus keeping the RMS wattage stable... The linear mechanical X-Max (distance cone can travel front to back) is a FULL 2 inches! This is incredible excursion from such a small driver! When I say this subwoofer matches the output of a traditional 10" subwoofer I'm not exaggerating... The voice-coil and motor assembly is modeled after Earthquakes MiniMe series with some concepts taken from their Magma subs as well. Third... Wrap this package up with an extremely efficient Earthquake class A/B digital amplifier, awesome X-over controls and 180 degree phase switching ability and you have something no other company could offer at this price. This amplifier runs at 100 watts RMS with 150 watts peak power output keeping strong power output consistent during the entire time you listen to music or watch movies... If anyone has had the pleasure of talking with professor Joseph Sahyoun of Earthquake Sound you would know the level of genius this man has in audio engineering. The level of quality craftsmanship and technology he puts into his products are something I greatly admire being an audiophile. Most people who have bought this truly don't know what they have. A word of advice; when you get this subwoofer, allow 1 week of proper break-in time to exercise the spider and motor assembly before turning it very high. When subwoofers are sent to you new from the factory, the spider is very stiff with very little play. As you break them in properly they loosen up allowing the sound reproduction to increase in SPL and accuracy/sensitivity. Cranking up a new subwoofer fresh out of the gates stresses the stiff spider and can break the seal between spider and speaker cone= blown sub. Keep the max volume at 65% or so for 4-7 days. A note on the proper application of this subwoofer. This sub is designed to be implemented a space no larger than 12' x 12' x 8' or similar sized rooms. I noticed a bad review from a gentleman who placed this in a kitchen. This is a misapplication of this product... Most kitchens are "open room" designs. In a vast open area like a kitchen you are going to lose your Sound Pressure Level (SPL) which leads to a flat bass response. This is a product designed for a bedroom home theater where the sound pressure is contained(door and windows closed). Another reviewer mentioned a "humming" noise from his sub, this is due to a bad rca line-out source. Traditional cheap rca line-out cables are unshielded. Being unshielded they can pick up EMF signals floating around from other cables, power sources, antenas etc... Using shielded high quality cables will help drastically. I use what is called a "power conditioner" on all my audio and video equipment. This reduces or eliminates interference, voltage fluctuations, over-voltage and damage to components from brown/black outs. If you appreciate a well-balanced audio system and are in the market for a subwoofer 10" or under, seriously consider this 6.5". Many people are afraid to buy a 6.5" for fear of it under-performing. Do NOT fret about this subs size, the technology is there to rival 10" subs...

Excellent customer service to start with, this subwoofer delivers great sound and bass.

I bought this to replace an 8-inch Yamaha subwoofer I'd been using for the last few years in order to be able to turn the bass up past a third without a farty distortion coming on for frequencies below 30 Hz. This thing fulfilled those expectations. When you crank it up during particularly bass-heavy club tracks, you do get some minor "farting," but this settles down if you play with equalizer settings a bit. At that volume, though, I had windows around my apartment visibly rattling, so I'm not sure that should even be an issue. Crossover settings are a welcome addition, and certainly make it easier to balance bass sound with the rest of your audio setup. Sound is clean, tight, and extends to around 25 Hz with a fairly flat response (although the 20 Hz response range quoted here is a bit optimistic without upping the < 31 Hz end in equalizer settings). All in all, much cleaner than any home subwoofer I've heard before, aside from my brother's BIC F12 - which is roughly equivalent in sound, to my ears. Construction is very sturdy. The rubber feet are beastly, which is important because you don't want this thing sliding back during every thump. I also like how the heat sink is internalized as opposed to sticking out the back, since it reduces the footprint of this thing compared to other 12-in. subwoofers out there I was looking at. Note: make sure you have the rear "auto" switch in the "on" or "auto" position when turning this on for the first time - I missed it and initially left it on "off," and was dismayed when the lights came on but no sound came on. If that happens to you, remember that it's probably you, not the subwoofer! The reason I give it 4 stars instead of 5 is due to the difference in price compared to other, similar 12-in. subwoofers on Amazon. For example, it's roughly $100 more expensive than the BIC F12, and $70 more than the JBL ES250PBK. However, I got this because (unlike the others) it had support for stereo RCA input, which I required due to the way my audio system is set up.
