With all due respect I've seen this type of response many times when someone talks about sub issues, it's like it's never the sub, it can't be can it?I think this may be mostly a setup issue, maybe even the buzzing. What sources, amps etc are you using, and how are they set?
Change everything else including cleaning your mains then the sub will be ok and the buzzing will supposedly finally stop
I've had other subs in the past and I had one that buzzed once as this one does. I was naive back then and went on the quest to resolve it. After changing loads of kit, making my own shielded leads etc to no avail, I finally changed the sub and bingo no more buzz
I've taken it off LFE now and the buzzing is reduced considerably which I can live with but you'd have thought so long in the game that BK would have resolved this issue by now
Although it doesn't sound that deep to me it's ok and I can live with that aspect to, it is certainly what I would describe as very quick and tight base, not boomy or bloated but it seems to be very narrow in the range at which it responds leaving a gap between the sats and sub.
Sats are set to small with cross over frequency of 90Hz and sub is set to 120Hz
I'm using the low level input only from a Yamaha AV receiver
It will do, it's small and superbly finished, too much WAF to change it but as I say in direct comparison to my Kef PSW2500 I remain underwhelmed on the sound integration
