X84SWS Shallow Woofer System

I have installed a lot of stereo systems, so I know a good sub when hear one, and subs this size generally dont really fulfill the role of "subwoofer" very well. These outperform any 8,10, even some 12 inch subs! The designers knew what they were doing when they came up with these. The bass is impressive, tight, controlled, and not boomy under heavy power. I definitely found every loose panel, screw, trim piece. These are worth every dime.

What you get in the box .... speaker, spacer with wiring and a trim ring (which wasn't necessary in my application.) Yes, you must cut the factory speaker connection. But the spacer ring makes the wiring easy. Just trim about 1/2 inch off the wire shielding, push down on the buttons, and insert. Set speaker into hole on top on the spacer ring and screw into place. No carpet trim was required. Replace factory cover. DONE! While the fit is great I'm not 100% sold on the cost. I've had other subwoofers with more boom for less money.

Phenomenal like night and day . They need a break in point but after … perfect.. it quite plug n play u will need to snip some wires, and some stripping. It after that it’s simple.. took me a hr self install

Sound great. Have a 400w amp supplying power. I had the Hi-Fi system and these easily outperform.Easy to replace. Make sure if you are snipping wires to cut as close to plug to leave room to strip and plug in. Have to remove all the plastic covers on the seats before unbolting and tilting back. I did not disconnect my battery while tilting the seats.

Fitted subs in factory enclosures, powering with JL Jd400/4. Complete transformation of the cabin, when you pump up the volume with bass heavy tracks, you can feel the seats vibrate with Bass. If you dont want to lose boot space with an enclosure, this is the perfect compromise!

I installed these subs into my BMW 335i e92 under my seats easy install and I have to say they are a huge upgrade from the stock subs

Although I didn’t take any photos, of the installation into my 2012 BMW 750, First off at least in the BMW F02, let me say these are high quality subs, (OMG) at last a product that fits, they fit perfectly under the seats into the OEM housing, without any problems, and I was able to install the OEM cover plate also. So when I tested the sound Quality I can clearly hear and feel the difference it is like night and day, You won’t believe the quality of deep bass, it’s truly amazing in fact it’s a shame BMW don’t use these in there logic systems for the low end, the sound is amazing. Okay the price point @ $265 is truly worth it, you can’t go wrong. I can’t compare to the others out there that retail for $500, but for half the price I paid they sound absolutely perfect in my install. From Jazz to HipHop these thing preform amazingly with deep low’s for HiPHop and the perfect lows for Jazz. so if your factory subwoofer sound disgusting take it from me try these you won’t be sorry.

Replaced the factory HiFi subs on my e92 with these. At the same time I also replaced it with 700/5 amp and boy I had no idea this car could produce these sub tones. The stock subs can't really do much of anything at all so these are a must. For HiFi users, you'll want the 2ohm subs if using factory amp or 600/6 amp. If using the 700/5 amp you'll want the 4ohm ones bridged to 2ohm mono. Hope that helps.

Install is straight forward other than the fact my stock speakers had 4 wires. These need to be bridged together and shoved into the speaker terminals which was some work. I installed them into the stock under seat speaker boxes they fit perfectly. Overall very good, they fit perfectly and sound really nice with the stock amp, worth the money for sure.

These sound better then the Harmon Kardon woofers my car came with. If you’re putting these in your bmw, you will need the adapter rings. You will notice the difference. After install I had to address loose side skirt issues for noise/vibration. These are not plug and play! You do not need to cut the factory connector off if you have some common sense.

After looking everywhere, it became very difficult to find a “free-air” shallow subwoofer. Thank goodness BMW uses this sub or I’m not sure I would’ve found what I was looking for. They ended up working perfect for my rear door sub setup for my IQC truck. Seriously, everything Earthquake makes bangs.

sound better but not sure I would order again

This is a good drop on replacement for a E93 M3 below seat subwoofer. Minor mods needed to make the connection, but straight forward.

👍👍

For such a shallow sub, it really kicks out the base. you can get it to clip very easy but it sounds outstanding.

Folks, i've got a pair of woofers for my 6 series convertible to add some punchy bass to my Logic7 system and what a difference it is!! I highly recommend it, amazing value for money. Sound has improved to a different level. Go for it!

Like most others with an E60 BMW with Logic 7 the bass was never punchy and overall flat. I installed the Earthquake's over the holiday and am beyond happy...Although I am far from an audiophile Boston to Pavarotti sound like I am sitting in concert. There are scores of people on the BMW forums that mention adding a dedicated amp to drive the subs, but, honestly these have made such a dramatic difference i would like to keep my low frequency hearing in my old age. Additionally, the cost savings over BSW and AlphaOne's is enough to have a nice dinner out. It is great to see a USA logo on a product that provides constant fulfillment/enjoyment. Thanks Abraham. If you are even remotely considering a BMW sub upgrade do not hesitate. Install the Earthquake's. FYI, the BMW installation rings are included so no need to buy them separate. This is not mentioned on the box or in the product info - so hopefully this will save someone a return.

These a the BEST SUBWOOFER BMW replacement speakers I have ever hear ! The bass in my BMW E90 is CRAZY . Also the company has the best Customer Service I have ever had the pleasure of dealing with . If you have a vehicle that has little room for sub woofers BUY THESE ONES !!!

Fit like a glove with the BMW adapter they sell separately. This was an upgrade to my bang and olfsun in my 2014 X5 F15. This thing (2× 4ohm) should have come with the $3k+ B&O system. A must have, you won't regret it. Careful on install with all the clips and covers... don't force anything. You will need about 6 inches extra of speaker wire (3 per side). Huge difference, be easy on them while they break in.

These subs exceeded my expectations. I had to EQ them a little bit since they were installed in small boxes. They sound great once tuned right.
