Subwoofers

Very musical sounding sub blends very nicely and easily with my bowers and Wilkins. But theres one big problem, it only turns on with high volumes. If youre listening to say 70-73 db volumes which I usually do it shuts off.
Was reading about this on other places and contacted kef customer service as well but they did not have any help with this. Only other option was using the lfe input. But for me, I wanted to use it with speaker level input.
So if youre listening to over 80db volumes its fine but if its around 70db or around its not gonna work.
Another thing is with really higher volumes which we rarely do listen to, it gets a bit boomy.

After talk to tech support I opted for 1 Kube 10b and it is fantastic. I paired this with the Sat Pack 205 and its a great match for my open concept theater room.

Got a KUBE 10b to connect with a pair of LSX speakers. An excellent combination !

They're great! Fast and accurate, without sounding boomy, bloated or tubby.

No matter what sort of music I run through them, they respond!
From movie sound tracks to extreme orchestral music, like Mahler or Shostakovich, to Wagnerian opera and organ music, they handle everything well.

I have a larger, more powerful subwoofer from another manufacturer in my main system. I needed a more compact one for my office setup, to augment my KEF LS50's. I'm shocked at the quality of this unit's sound. It's fast attack and rapid decay is rare in a sub at this cost level, making it a bargain. It absolutely pounds me when asked, keeping right up with the LS50's in seamless harmony. I now want to replace the one on my main system with it's bigger brother, the Kube 12b!

This review is for the Kube2. Excellent base response and customization options. Side firing speaker opens up a lot more possibilities for locating speaker in the room
