    Wanted Looking for a 2nd hand BK XXLS400

    Looking for a BK XXLS400 in good condition, no humming/noises, etc., ideally in white or black, not too old (up to 3 years is ok), minor scratches are ok. Prefer to listen to the sub on pick up, up to couple of hours driving is ok, if the deal is good enough. Any offers?

    Auto on/off on BK subs

    I wonder how does the Auto on/off function works on those recent BK XXLS400 and P12-300 models that don't have a dedicated Auto on/off switch. Do these subs not have the Auto function or it is there but can't bypassed?

    BK Electronics XXLS400 Sub for Music?

    I'm looking at buying a BK Electronics XXLS400 Sub, whilst it will be dual purpose Surround / Stereo use I'm only really bothered about the stereo in terms of sound quality and would happily sacrifice surround / movie quality for better stereo.

    BK XXLS400 buzzing

    My Subwoofer is completely unusable as as soon as it has power applied it makes a horrendous buzzing noise. After a bit of googling it appears it could be internal capacitors to blame. I'd like to take the amp out for a look but it doesn't seem keen to come out. Does anyone know If it's glued...

    BK Monolith or BK P12-300 SB-PR

    Hi guys Has anyone owned or done a comparison of the BK Monolith with the new P12-300 SB-PR (P12-300 with passive radiator)? I currently have a BK Monolith and thinking of adding another one but would prefer smaller subs with similar performance. I tried a pair of XTZ 12.17's but they didn't...

    BK Monolith plus Hum at higher gain

    There is a noticeable hum from my Monolith when going past 12. o clock on the gain. It only hums when connected to the source. No hub when RCA is disconnected. If I move the socket end on the cable it goes even louder. I don't mind a little hum but his is noticeable and annoying. Any ideas?

    Hi, Thanks for everyone's help in sorting out my amp/speaker/furniture config in my office. I've settled on the NAD M10 amp at least in part because of the Dirac Live helping out (I've finally got it sounding decent with Dirac using the 'curtains' as per someone's suggestion. Triangle Comete...

    BK XXLS400 sub no sound

    Facing BK Mono + towards wall?

    I'm considering facing my BK Mono + towards the wall, would this cause any problems or make it sound different? The reason is my 14 month is getting too curious for comfort and pulling the front off and poking at it, and I can see one day he's either going to soak it or stab it with a pen. But...

    Long ago (2008), I bought a BK Gemini I sub. I was happy with it for many years but, in 2020, it developed a significant mains hum. After some discussion, I not only bought the newer Gemini II but also had the Gemini I repaired since the repair was just £35 including return shipping. So, I...
