Who needs cinemas?
Fed up of youngsters talking all the way through the film?
Frustrated with constant sound of crinkling sweet wrappers?
Wondering if your back will survive another round in the seatback kicking contest?
Salvation is at hand in the svelte form of BK's XXLS-400 subwoofer.
Take your time over setup and you will, like I, begin to adopt a routine of home cinema viewing without parallel at this price.
Rumbles when it should and disappears into the overall sound field just as it should.
First class all round and I'm darned if I can spot any blemishes in an item described as grade B; it looks brand new to me.Read full review

Awesome smooth bass
Best thing I have ever purchased on eBay. Phenomenally deep and rich bass which has the ability to fill a room comfortably. Incredibly flexible from a subtle colourful edge to double bass, to a punchy attack of explosions in movies. Can’t recommend highly enoughRead full review

Bk xxls400 subwoofer
This subwoofer is absolutely fantastic, such good value for money, much much better than a previously Rel subwoofer I had at over twice the price. The sound is very fast, detailed, punchy and extends fantastically deep. This is comparable to a rel s3 SHO that cost £1599. I pay less than a third of this cost for the bk.
Nothing can touch this sub for the money. Absolutely bargain. The quality is fantastic and the real wood veneer case is absolutely beautiful, it puts my bowers and Wilkins floor standing speaker cabinets to shame! Read full review

This is a great sub and packs a significant punch and looks great - kind of stealth looking.
It is a well-made bit of kit and extremely heavy - if you want to be safe, this is a two-man job for lifting. I haven't given it a thorough test, but I am satisfied with what I have heard.

Beautifully made, awesome sounding
I literally had to secure items around the house so they don't fall off the walls or shelves. Even at very low volumes the sound difference is amazing paired with a pair of microlab 9c's and 7's. Very well packaged for deliveryRead full review

BK subwoofer
Excellent performance, well finished with quality fittings. I replaced an REL with this and it digs deep with no overhang. Fits into the room for good WAF.

An amazing sub
Love this sub, from the moment I ran my amps test tone you could tell that this was something special. Made watching TV even better.

Quality piece of kit
Adds real depth to music and films, can't believe how much better it sounds.

BK CXLS400 Subwoofer
Beautifully finished, with a tight sound to match. And it doesn't take up the whole room.
