PUMP-12
12-INCH PASSIVE MODULE
Earthquake Sound is proud to present to you the PUMP-12 passive
radiator module. Essentially two horn loaded 12-inch passive
radiators, the PUMP-12 has many different applications and uses.
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.

Specifications are subject to change without notice.
As you can see, the green area is 30% less than the yellow area. This
means the down current of the PUMPed enclosure is 30% less than
that of the regular sealed box enclosure. With less down current, 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.
The PU MP-12 works great with the following subwoofer
combinations:
One 10-inch subwoofer + one PUMP-12
One 12-inch subwoofer + one PUMP-12
One 15-inch subwoofer + one PUMP-12
Two 10-inch subwoofers + one PUMP-12
Two 12-inch 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.).
