So did you then hook it back up and it is still not working? I'm thinking maybe you had an oxidized connection at the crossover and now if you re connect it will work. Those tweeters are fragile beasts. Many of us have blown 1 or 2.

OMG...for reals?

The last one that says exit is usually 1/4 mile from the actual exit. I get off the fuel then and just let it roll to the exit,
Ah..if you're on the interstate you are not supposed to decelerate until you are on the exit ramp...... just sayin'

It can't be done, it's impossible, we'll all be killed
Of course you can split a low impedance output (like the sub out from your receiver) through a Y cable into 2 relatively high input impedance inputs. Will you have phase cancellation problems at the low freqs? that you can hear? Maybe. But 2 subs will help out with room modes but you know that, that is why you have 2.

I think .....read THINK Trey was part of the layoff a little while back.

Roy, @Chief bonehead is this guy @HenningO SOL? No current Klipsch driver or replacement diaphragm will work in his Palladium tweeters? Maybe he will have to replace both L and R even though only one is blown to keep them matched?

That is a completely different spec. don't confuse it with "input sensitivity" is a real world specification.
I seriously don't know why this is going on and on...

re. input sensitivity..... that is the specification of how much signal at the input will drive the amp to its full unclipped/undistorted output? One can figure the "gain"(closed loop) from that I think.
Kinda like this...?

Not 100% sure, but I think I changed the input sensitivity to 2V and raised the input impedance to 56k or something like that. I wanted to be able to drive it with a BBX. The sonic change came from the faster OpAmp and boutique caps.
You changed the Zin to 47K. And the gain from26dB to about 17.5dB. All this of course if the list of your changes that I obtained from @Marvel is correct.

Ok good guys, how can we help this guy? I'd be pissed too. How long has this been discontinued? No after market diaphragms anywhere?

Add feedback lose closed loop gain, G.... and of course the reverse. Definitely one of the reactions to that action.
Fixed it fer ya. And closed loop gain is the figure that is always spec'd by manufacturers of Audio Amps as "gain".

Just one easily searchable example that gain and feedback have an intimate relationship.

K1 or K2 have less negative FB? I believe on my K2s it is selectable. 26dB gain or 1.4v for full output which is even more gain. My D75s are 26 dB gain. Also I think Mark turned down the gain on the "Duke".

Hold on a second. How many "old" LaScalas do you have @filbertr? If only 2 you will need something for the center channel. The center channel(dialouge) is quite important in HT.

A hollow wall with sheetrock on both sides is like a bass drum. Filling the cavity WILL help. Again we just don't know how much without measurements.

Wish I had known to install Rockwool Safe-n-Sound into the interior walls while my house was being built. It was a lot of extra work to retrofit when dealing with some low frequency standing waves in my listening room.
What was in the walls before retrofit? The pink stuff? And changing to rockwool helped LF standing waves? Got any measurements?

Is there a schematic for this B & K Sound crossover?
