Mine are 74 raw fir with what looks like oak veneer put on by the original owner.
How rare is the marine grade fir? Does it decrease value to stain it or re veneer it? When people like heritage klipsch, it seems it’s for the quality of build using birch wether it was veneered or stained instead of current mdf with veneer over it.

Location? I need a center belle!

Yep i see that now!

Makes sense. You still have the room for the top plate to hit the wall corners. So your vertical back plate was still sitting flush against the corners then? I see how that's not the issue now. Hmm. I don't know what else to tell you then. As long as they sound great now. Just wish we could have figured out the issue before just in case you come across it again.

Here I just tried to take a photo for a reference of what I’m talking about. I slid the top hat forward so you can see how the back sits against each corner of the wall- i have pipe insulation up and down the back vertical plate and to the sides of the top hat
Please excuse the unfinished paint lol

Your top plate sticking out like that is the issue imo. You need to saw that flat with that vertical back plate. You're essentially having your bass bins stick out from the walls due to that top plate hitting the wall before the rest. I hope im making sense.

I just googled images of rear klipschorns. Are yours DIY? That that top plate sticking out like that shouldn't be that way. It's keeping the bass bin from being tight in the corner with the pipe insulation.

interesting. I thought that vertical flat back plate needed to be against the wall but the top plate sticks out keeping it from sitting flush in the corners. Haven't seen that. Mine aren't like that but mine are decorators so...

Glad they are doing better for you, after all these years it just shows, little changes can make a big difference.
I am not one for changes to a design but you really need to put new cape in those old crossovers, you really do.
I have some split LaScala tops with AA crossovers, (same as Khorn tops) they had old original oil can caps so bad they were starting to leak. The caps were changed and the design was kept stock, I didn't expect much difference. I was shocked at the difference, being old and half deaf I didn't have high expectations but I was completely wrong. The sound was easily better, highs and midrange were clearer and crisper and the bass was even better.
If you can solder I would order new caps and do it yourself, if not get someone to do it for you, it will be worth it if it is anything like mine was. I didn't know it was as bad as it was, you get use to how it sounds untill you change, then it's like wow I had no idea they were that bad.
Thanks but Deans got me covered! He’s building me some AAs! I got more excited when I read people’s realization how great it is to freshen up the crossovers.
My first experience was listening to la scalas with deans networks compared to make stock AL. I couldn’t believe it. Though ALs are supposed to be the worst

I can't tell a difference between pipe insulation and without. Bass is great either way and that's with tired old AA's from 1974.

Are there first reflection points to the sides of the horns for Klipschorns or were they designed not to have those reflections? I tried the mirror test and I never see the Klipschorn on the front or side wall. Is that absorption better used on the back wall or is it still necessary to have absorption on both front and side wall of the horns anyway?

Beautiful. Wish you were closer for a center for my new KHorns.
Unrelated but I was wonder if my badges were original. Seeing them on your belle means they are!

Just spend big on the Forte crossovers, get Ti tweeters if you don’t already have them and spend on room treatment. If the wife disapproves, find other ways using furniture, book cases, thick drapes, thicker rug etc.
I do think for now your cheapest way is to play with placement. Go longer on the wall and toe them In at your listening position possibly could help with that room

Since it seems you can’t pull them out from the back wall too much, Cornwall III,II, I or Chorus I, CF-3 or 4 or KLF-20 Or 30 would work well for you. I know reference is seen more for movies but the RF-7 III is outstanding and really improved on the II’s brightness with very smooth highs. I think you’d be very happy with that as well. I’d avoid passive radiator Klipsch speakers.

From 1976-1978, so laser tags and AA crossovers.
Since you seem to have knowledge on years and badges would you happen to know if these badges and grill cloth are original on my 76 raw fir decorators?

I could never get into the idea of the CWIII having the smaller heresy mid horn. Never heard a pair though so can’t judge. I’m happy with my Chorus II and my newly acquired Klipschorns
A Chorus III with the same or larger mid horn with mumps and new compression drivers and tweeters and network would sure make me day dream though. How about just a pro version with the ability to upgrade your Chorus II to “III” via the pro parts?

Oh absolutely not disputing or arguing for one over the other. Was just mentioning how it’s the closest thing we’ll probably ever see to a “Chorus III.” I’ve heard neither but I’m sure they’re both amazing with the k510 being the next best thing to a 402

The 396 is a 2 way with the K510
The KI-362-II is the closest thing to a Chorus III you can get. The same horns and drivers as a FIII with a 15” woofer in a smaller cabinet. I wonder if you could fit them into a Chorus II cabinet and make a Chorus III of sorts with the passive. Might need to alter the crossover? The mid horn is smaller than the Chorus II though.

Photo is a little fuzzy. Is that lambswool?
Here’s a better look

I’ll have my seating against the back wall soon as well. I only have similar bass traps to put at the reflection point on that rear wall. Would that be enough or will I have to do more like hang up a large thick curtain on the wall? I know acoustic solutions has a carpet like absorption you can glue to walls so that could be an option but both the curtain and the carpet are a bit much for me. I’d rather get more absorption panels than those options.

Interesting set up and very nice room. I'll be rearranging soon to similar distance listening and against the back wall due to the KHorns needing the long wall and i had already been researching diffusion panels. Everything i read recommended them on the back wall reflection point, but you're saying the opposite huh? Maybe i won't need any after all. Do the bass traps work well on the back wall? I've normally used them behind the speakers in the corners with short wall placement, but i suppose i can use mine on the back wall as well with similar sized square absorption panels like yours on the first reflection points to the inside of the speakers, and having heavy drapes to the outside of the speakers. I'll have 1 thinner but long and wide panel left i can use directly in the middle under the tv horizontally, but does it have to be tweeter height? Wouldn't the tv be tweeter height with the taller KHorns and the reflections would happen there?
As far as diffusion, i've also recently read that 1 panel can do just as much for you over multiple, but again, that was back wall. Do you have a link to the diffusion panels you use?- 1

Digital to your preamp should be exactly the same--i.e., you're not using the DACs in your player. Are you "converting to LPCM" or using "raw bitstream" in either player?
EDIT: The reason why I ask is because I've experienced a large difference in sound quality when the player converted to LPCM (i.e., a loss of SQ). The "raw bitstream" setting is usually heavily preferred, in my experience. There is something audibly lost in the conversion to LPCM in some players.
Chris
What about PCM or bitstream? IIRC people say to use pcm instead of bitstream on tv Audio setting when connected to your AVR and also same settings on the PlayStation 4. Should be set them to bitstream in order to use the dac in my marantz avr without conversion?

Do non electrolytic crossover caps really need replacing?
