My most popular subwoofer delivering 135dB SPL. I only talk about RMS ratings but if you are comparing with inferior brands the BB218 program power is 4000w and the peak power is 8000w per cabinet.

I never use other people’s drivers in my subwoofers. I make my own as I want to match the drivers perfectly to the cabinet and our cabinets have stood the test of time for over 20 years. We carry spares and replacement parts but rarely need them.

The stack you see below delivers 12000w RMS and is perfect for large venues or outside use.

Remember there are no middlemen at Bishopsound. We design, manufacture and sell directly to you. You will only find our Carlsbro or Bishopsound in music shops if it is Pre-used.

No middlemen at Bishopsound means fantastic value for money and great savings for you.

Enjoy the punchy tight bass of our best ever twin 18″ sub. Bob Marley and Level 42 have never sounded as good.

    Our #BishopSound 218 subs are loaded with 2 x 1250w RMS drivers. We have 4 x 218 subs, which gives 10,000w of LF (that’s 20k program. When setup with a professional live sound rack management system, amps, crossover, and compressor limiter, we are able to get a low bass frequency of up to 110db. The sound quality is amazing and we get comments from events organizers when we do the sound for live music or DJ events. The subs are incredible! When the bass drops on DnB events it makes some feel funny 🙂 The DJs are amazed and can’t believe the tight low bass we get from these #BishopSound 218 delta cabs. I recommend these for any event!
