PRV Audio’s 18SW2400 subwoofer is designed for professional audio applications requiring high power handling and low distortion.

  • 31 mm Height, 4″ voice coil handles 2400 watts Program RMS

  • Over 12.5 mm of Xmax for deep bass reproduction

  • High BL motor for impressive control and massive output

  • For maximum power handling, there is under-spider venting

  • When loaded in small boxes, it produces big sound

With its extended low-end response, great performance is realized in vented boxes as small as 7 cu. ft. This makes it ideal for applications where space is limited but powerful, deep bass is needed.

  *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.
