ComparePUMP-12 Passive Radiator Module
A unique and patented passive radiator module, the PUMP-12 is essentially two horn loaded 12″ passive radiators that adds diverse implementation possibilities to our existing lineup of SLAPS passive drivers. Earthquake Passive Radiators provide additional bass, without additional amplifier power or enclosure volume. Designed to perfectly complement all good quality long-throw woofers on the market. SLAPS/Pump-12 add up to +6dB of bass compared to regular sealed and ported enclosures. They can be integrated into virtually any sub/cabinet combination.
The PUMP-12 works great with the following active subwoofer combinations:
- One 10″ subwoofer + one PUMP-12
- One 12″ subwoofer + one PUMP-12
- One 15″ subwoofer + one PUMP-12
- Two 10″ subwoofers + one PUMP-12
- Two 12″ subwoofers + one PUMP-12
When selecting which active driver(s) to use with the PUMP-12, it is important to make sure that the combined piston area of the active driver(s) does not exceed that of the PUMP-12 (226 sq.in.).
Recommended Enclosure Size:
The PUMP-12 requires 9″ x 14″ x 14″ of installation space. Take the recommended sealed enclosure dimensions of the chosen active driver and add the 9″ x 14″ x 14″ to it. We recommend sanding the cutout hole and pushing the module’s dust caps inwards to allows the PUMP-12 to go through the cutout hole without damaging the surrounds.
Pump-12 enables the transfer of high amplifier power into low frequency output. Since the active driver does not have to fight against increasing pneumatic pressure in a closed cabinet or over-excursion close to a port tuning frequency. In a closed cabinet design the pneumatic loading of the woofer increases as a function of its travel, this causes compression. Pump technology possesses none of these limitations.
When using a sealed enclosure, there is one peak of resonant frequency at which the amplifier draws the least current. The graphs below illustrate the difference between a typical sealed box enclosure and the PUMPed box enclosure.
The Graph shows the green area is 30% less than the yellow area. This means the amplifier current draw of the PUMPed enclosure is 30% less than that of the regular sealed box enclosure. With less current draw, the speaker’s impedance increases and therefore, SPL also increases. In summary, the PUMP-12 increases the subwoofer’s SPL by 6dB without the need to draw more amplifier current.
RatingAwesome product, supplements my already-decent (homemade) sub, easily installed, increases low bass volume tremendously. Really releases cabinet backwave.
These things are legit. This guys complaining about no spider!! COME ON MAN!!...If you ever used a slaps passive radiator then u know it don't need it...next they're going to complain about "there's not even any terminals to hook up this cheap thingy." SSSSHHHHHH:/ these are for high excursion competition subs for 1/2 to 1/3 of the price of those crappy dayton audio with a fake a!@ spider for 200. If your surround isn't the same size or better then yea buy the mid bass looking Dayton for mediocre bass and inferior/,*$ product....JS
I went from bass to shaking floor boards. This things a monster
I mounted mine on the outside. Inside a Klein audio 13” sub box was to spec actually a little smaller because I didn’t account for the volume of the unit that’s why I put it outside not only did it hit like crazy but kinda cool to watch the radiators loud like crazy. I know this speaker is too big for these but these never bottomed out and I hit them hard. Plus a great conversation piece for sure pics to come soon
Haven't been able to install this myself but have heard a friends with one installed in a car. Sounds phenomenal! Thing is, you need a pretty big box. I have two 10's in a custom box and i can't fit it anywhere. Make sure you measure first and have room for this as the top is rather large and it requires quite a bit of depth to install. I think i may use this in a home subwoofer box.
