Ready for dispatch in 30 working days

The NEW Mark II active dual sub is now released. The BB218SA is much louder than the single or past dual 18" active subwoofer. Making the classic BB218 passive into an active cabinet with punch has taken us 12 months. For those who prefer not to carry an amp rack the BB218SA is the perfect choice. We have thrown away the standard push in IEC kettle leads and added PowerCON push and twist power inputs to prevent cable kick outs and ensure a safe and secure connection.

The BB218AS thumps a minimum of 139dB SPL @1w/1m and has a frequency range of between 28Hz and 280Hz.

The Twin 18" powered subwoofer incorporates a pair of the hugely sought after BDP18 1000w RMS cast alloy woofers designed and engineered in the UK. The BDP18 has sales of over 1,000 units and no re-cone kits have been needed. Reliability is at the heart of everything we do!

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

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!
