Made in Britain from 18mm 13-ply braced, air pocket free BB grade birch plywood and 1000w RMS (4000w peak). Available in 4 ohms and 8 ohms.
British engineering enables this ported subwoofer to go down to 30 Hz - with a max SPL of 134dB. We manufacture the cast alloy 1kw driver so we control the performance and quality of this subwoofer.
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.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.
