Thanks team Klipsch for helping me with the polarity question on my KPT-942's. They're sounding great.
So. To recap I'm feeding a Xilica 4080 with a Bluesound Node 2i. The Amp is a Monolith 7x200 and speaks are KPT-942s. Everything Sounds Good.
I've noticed that with 0db input gain and 0db output gain the input meters don't light up.
As a Common Operating Procedure should I increase input gain until the meters are short of clipping and reduce output gain to a standard listening level?
I suppose im trying to "optimize" the amount of volts being sent to the amp input.
Please bear with me as I'm learning. There isn't really a "problem" im trying to resolve just to establish S.O.P.
Thank you all great folks

First of all I need to reach out and show my gratitude to @Chris A @Chief bonehead @Dave A @richieb@mikebse2a3@babadono for helping me step through this.
It turns out that there was a polarity mismatch. Two of the four woofers were pushing and the other two were sucking.
60 seconds with a screwdriver fixed the problem. Now I have LF response again. lol
Next question which I will save for another thread is GAIN.

Hi everyone,
I reset my gain and my right still sounds thin. I need to run to the store but I want to post these.

Have you tried a different channel on the amp, if I understand you have 7 to choose from.
Yes sir tried several other channels. Same result. As well as outputs on the xilica

Bypass is enabled on PEQ filters 5,6,7,and 8 on left channel. Level is 0dB so should not make any difference....but
Ok I added bypass tonight for grins. Left channel is great. Right channel has the bass problems. I’ll back out the bypass. Thanks for bringing it up.

Chris, Post all four channels here. Need to see what is different. Chris is the resident Xilica guru. Do your neighbors love you yet?
@Dave A this has been a fantastic project. I'm 95% of the way there. I'm so glad to hear from you. I don't have any neighbors on the adjoining lots but my wife is loving me, that's for sure.

Here are the left high pass and low pass settings.

Hello,
I have the 942 b(4) connected to a monolith 7x200 fed by a bluesound node2i. I swapped out some passive crossovers with the xilica.
I have the L and R from the node2i coming into input 1 and 2. The channel 1 output goes to the right 402 horn, the channel 2 out goes to the left 402 horn, the channel 3 out goes to the right bass box and 4 out goes to the left bass box.
I've noticed that the bass from the right bass box is nearly non existant while the left bass box will drive you out of the house. I know I'm missing something here.
I"m attaching my high pass and low pass xilica settings for any help you can provide. Thank you. Please help.
Christopher

A heads up
Yeah there was a guy on the north shore that accepted my offer but would never set a date to pick up the LS’s.
I’ve gone ahead and picked up 942/4’s instead

"Thanks for the help. The problem is now resolved after tightening the horn nuts 🥳"
As it turns out Chris did not tighten the mounting bolts all the way down. When he double checked and found the loose fasteners the problem went away according to an email I got yesterday. We had to disassemble these to get it all in his truck and reassembly had a minor glitch. I have to tell you they filled that short bed and the crew cab.
Hi Dave,
Thanks for checking in. Yes indeed that helped a lot but I’m still getting a strange vibration. I know it will be something simple.

Following. They look like one heck of a driver.

I’m not quite sure mine is a different driver and bolts directly to the horn flange. Might check and make sure the driver is installed correctly to the horn and all hardware is tight.
Yeah based on @Chris A photos my driver looks like an 1132 with a snout. I’m hopeful a DE750 will bolt right up to it.

Have you removed the driver from the mount to check gasket/attachment points? Or am I missing something here?
The other issue im pondering is that the rattle is being caused by feeding .3-.8 kHz to a driver that’s rated to crossover at .8. through a kpt-535 crossover. When I get the xilica dialed in I think my rattle might go away.

No sir I haven’t checked that yet.

Ok I got the speakers and they sound fantastic but at higher levels the horn diaphragm rattles. The driver doesn’t have a label on it so I can’t identify it. I think I need new drivers though.
-
I’ve got a 402 with an unknown driver. It rattles and I think it needs an upgrade or replacement . What should I try? Thanks team.

I may be crazy,
But I have an opportunity to get a pair of KPT-942/4’s at a great price. My listening room is about 24x30. I know this will probably blow the neighbor’s heads off but I’ve heard that with proper toe-in you can get a sweet spot 9’ out. Am I out of my mind or should I bathe in the KPT glory?
Thanks,
CJ

Bumping for fun.

Hello, I’m browsing for a pair of la scalas within a reasonable 6-7 hour drive from New Orleans. I haven’t set a budget or year yet as I don’t 100% know what I’m looking for. I just recall seeing them as a kid in the ‘80s and always wanting a pair.
Thanks,
CJ

KPT-942-4 Xilica tips

It was at the terminal block on the bass box. Perhaps had one too many adult sodas when putting it together
