Delta 18" is my 100% 18mm 13 ply Birch Marine Plywood Passive Subwoofer

Each cabinet delivers 1000w RMS (4000w Peak) at 8 Ohm and goes down to 34 Hz - with 134dB 1w-1m. We make the cast alloy 1kw driver so we can control the performance to perfection!

The Delta 18″ Subwoofer we believe provides the tightest and most defined bass frequency response available in the UK today. We make the box and the driver and the driver is the BDP18, probably the most reliable 18" cast alloy driver in the UK today with over 5000 pieces sold and only 6 have come back for a re-cone.

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. The box has been tuned to perfection after 30 years of manufacture and it sounds as punchy and stomach punchy today as it ever did! No crossover is fitted in the box as all users should use a speaker management processor.

This system delivers on all levels. Recently more people are moving away from 12" or 15" to 10" to get clarity as the subs will take care of all the low frequencies.

The combination of a 10" with 18" subs are considered by many, the sweetest of sound partnerships.

Perfect for a Bar or a Club install or a band as 2 of the 10"s can be used as side fill or wedge monitors.

The amplifier to drive this is:

1 x BP44k - see

Acoustic foam behind all the grills prevents dust and moisture ingression.

The tone is British and designed for our music. Watch your customers come in off the streets, sit up with jaws dropped whilst listening to our amazing clarity of tone and punchy bass. No frequency is overlooked especially the mid-range! We are British!

This system delivers that signature clarity and that tight punchy bass that is the essence of Bishopsound.
