Ready for dispatch in 30 working days

Mark II version is made of 18mm Birch Plywood, seasoned and sealed with a new improved power module to tighten up the bass.

Following the huge success of the BDP18 Cast Alloy 1000w woofer that is loaded into the Bishopsound BB118S Single 18" passive sub woofer and the BB218S we have now taken the next step and made both active by adding our new sub woofer power module.

The 20mm screw-in professional Top Hat in the top allows you to put a 35mm extendable pole in and add a 10",12″ or 15″ top cabinet. This fixture gives far greater stability than a standard pole

Combine this sub the BB215A or an Orion for the perfect fully active system.

The single 18" powered sub woofer incorporates the hugely sought after BDP18 1000w RMS cast alloy driver designed and engineered in the UK. The BDP18 has sales of over 1000 units and no re-cone kits have been needed (even though we carry them in stock).

The BB118AS delivers a minimum of 135dB SPL @1w/1m and has a frequency range of between 30Hz and 300Hz.

Two simple, uncomplicated potentiometers on the rear panel control the volume and low pass filter.

Channel A and Channel B can be fed by XLR or 1/4" jack and a link out allows you to feed the original signal to multiple active sub woofers or mid/top range active cabinets.

A major benefit of Bishopsound Active Subwoofer Range is the Genuine Neutrik PowerCON IN/OUT through connector. All to often mains IEC power leads are kicked out or fall out in the middle of a gig. Locking mains cables for ground level Bishopsound active subwoofers are essential.

The 20a rating of the powercon exceeds the current needed thereby delivering greater safety and reliability.

The powerCON is a locking 3 conductor equipment AC connector with contacts for line, neutral and pre-mating ground contact. It replaces appliance couplers (often referred to as kettle leads) wherever a very rugged solution in combination with a locking device is needed in order to guarantee a safe power connection. The powerCON is a connector without breaking capacity, i.e. the powerCON should not be connected or disconnected under load or live!
