Features

Designed specifically to ensure proper cooling for long hard play, the 15W1800 delivers subwoofer type performance while enhancing your midbass output. It also features an side forced air ventilation system to ensure proper cooling for long hard play.

The durable spider and woven surround offer precise movement along with its impressive 9.5mm Xmax. Non-pressed pulp cone offers a natural classic tone found in most high-end PA speaker cabinets, making the 15W1800 an ideal woofer option for both ported and sealed speakers.

The upgraded and advanced voice coil and cone material along with its ability to reproduce extremely low frequencies will forever make this your woofer of choice to replace your existing speaker. The large 4” voice coil accepts the abuse of higher power systems while staying cool with the side forced air cooling system.

  ^{*Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range. **Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation. ***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.}
