Made from 18mm 13 ply Birch Marine Plywood and boasting 1000w RMS.

Each passive cabinet delivers 1000w RMS (4000w Peak) at 8 Ohm and goes down to 37 Hz - with a max SPL of 134dB. We make the cast alloy 1kw driver so we control the performance of this subwoofer to perfection!

The cabinet is finished in 4 coats of Heavy Duty black splatter PU paint it will withstand all the knocks and scrapes gathered through touring. No crossover is fitted in the box as all users should use a speaker management processor.

Join hundreds of delighted touring companies, live bands, Dj's, Club Installers and houses of worship in celebrating the sound from this subwoofer.

Be it on-tour, a nightclub or House of Worship, the low-frequency response will move the audience during reproduction of the spoken word, recorded and live music.

Important information about subwoofers

Subwoofers are designed to reproduce low bass audio signals between 30Hz and 150Hz. Driving them with full frequencies will cause permanent damage, so they should only be operated with a passive low-pass filter, a crossover network, or an active electronic crossover or speaker management system.
