Roger, sorry, so what are you recommending? Not clear from your sentence. The BF 210 or 212, and these are much better than the descent, I assume. For me the 80 to 200 or whatever the region, where the baritone's voice is, and where tympani and bass drum strike, is very important. When your Subs are off is this absent, and when BF subs are on, is this present?
Greeeting Ked and Ron
I agree that naturally there is an issue with the CLX in 100-200 region
I have measured this in room, and it’s a definite dip
In my case I am running 5 subwoofers and adjusted the bass panel crossover
The timpani, Drums and plucked double bass are outstanding
On Blow up, the drum roll at the end of aquamarine hits you in the chest
Also you need amps that love the impedance of the bass panels
This includes tubes, 211, el 34, and I am told Conrad Johnson
In solid state it seems to be less , I am told pass labs, though no personal experience
I use Goldmund which is great match and big el34 amps
I will try on my return to Europe the Lamm 1.2; but my issue with the lamms before was clipping in my largish room even the 2.2 I had before clipped
CLX set up is critical to get the bass coupled to the room, and normal speaker set up is all wrong for the CLX
Also the axis of the listener to the two panels to get the correct power factor between the mid panel and the bass panel
Since I put the CLX back into the system after 18 months
I have been shocked by the sound I am getting
I put this down to the Goldmund’s, better room positioning and the DA2
Just my 2 cents...
