PM-ed. Best Regards

also requested photos

thanks for all the great information. unfortunately while i was hemming and hawing, the pair of raw birch la scalas that i was aiming for got sold out from under me. it has been a pristine pair all its life then got stacked in a garage for a very brief moment...hence the top scratches due to the feet from the one placed on top of it. anyhow someone wiser than me now owns them (altho i have a pair of finished raw birch i still need to "unfinish"

PM sent on crossovers

thanks a lot, abe. i guess the grain is still intact so that means the veneer is still there. i will try the iron. my other question was about how to maintain raw birch in a way that keeps it as original as possible but while giving it adequate protection from the elements. is that a well known topic?

I was curious if anyone had best practices to repair scratches in raw birch ply, without having to finish the raw or veneer. That is keeping the birch raw is ideal. I'd doubt everyone's with me on this, but I like the look of the raw birch. What is the minimum one can or should do to the raw birch to offer reasonable protection to the wood from finger oils and humidity? Will any type of sanding effectively change the raw birch look and thus necessitate some refinishing? I Can dampening the scratch help raise the wood improve the look of the scratch? Filling seems a last resort. as the result can't be acceptable as-is, I would imagine. Sorry for the newbie naiveté. Thanks

Sorry to hear about your wife's rectal ca. I had it and beat it some 13 years ago now, so if you or she needs any support or question feel free to PM me. Take care lil jack

That's a good suggestion. I'll play around with that too. I agree with the other observation that the bass is limited, not weak. I'm more than charmed by the open highs too and only notice the bass when A/B-ing them to other speakers such as B&W. Li'l Jack

Thanks Bruce. I didn't realize it also boosts the Treble too. I later discovered that the loudness circuitry should automatically compensate when the volume is increased to reduce it's effect. Meaning if I can hear a big difference at the volume Im listening at, then that's exactly the volume range that the loudness switch was designed for in the first place. Hi Russ, I was referring to the La Scala too, which is also considered weak in the bass department. Although it has the same woofer as the Cornwall, the ported design of the cornwall gives a better bass response. I have a pair of each and can confirm. Certainly the La Scala has better bass than the Heresy though.

Hi all, I was wondering... The Klipsch heritage line is known for their high sensitivity and their relatively weak bass, and the loudness button on 70s receivers were deployed to replace compensate for low freq at lower volumes. Is that a marriage made in heaven? In other words would it always make sense to generally use the Loudness switch on a Klipsch heritage line? I guess technically Loudness is for low volume which is not the same as input power. At least for the moderate volumes I listen to, it tends to sound more accurate with the Loudness on, but them again Im 50 and my hearing isn't so hot. On a Marantz 2230 I've usually got it around 25% on the volume control ps. posted under updates and mods which isn't really right...so apologies if this posting was in error. LilJack

Gosh, Many Thanks. Both advices helped solve the problem for me. I believe it was the oxidation. After getting some flaky readings across the strip I cleaned out a bunch of dust, spraying some contact cleaner, scraped a little, and voila! Balanced tweeter output. Now that I hear the AL work, I can establish a baseline of critical listening. I'd say right away that it doesn't sound bad yet I could imagine it sounding better. I'm wondering if I should find an AA to A to swap in for a bit before going right for a A/4500 CT-125 combo. I noticed one of the inductors is missing the plastic cap. I assume that is of no particular electrical significance. Regards, Li'l Jack

Hi all, I have a question regarding what typically fails on an AL crossover. I have a pair of early-mid 80's La Scalas. I noticed one of the tweeters is muffled, and at the same time I think the squawker is outputting more. The DC resistance of the tweetr is fine, above 6. I ended up swapping the AL crossovers between the 2 speakers and sure enough, it is singing again. So my question is what typically goes wrong on an AL crossover with respect to the tweeter circuit, and if the squawker sounded louder too does that give a clue as to what is wrong? I have a regular multimeter. I know I need to replace the AL's eventually but just wanted to keep them up and running for the time being. Thanks all, Li'l Jack.

thanks for the info, djk! i do see the 7 cores from the side although the two thin veneers are too thin for me to see. But yeah, it seemed to make sense to me that I could use regular plywood for the bottoms. Now I'm wondering if these are also sort of decorator la scalas because there are no grills, the edges of sides are flush with the face, and the logo is mounted on the face (vs the grill). Then again, I read that there were no real decorator la scalas to speak of since they were all essentially plywood. Best, li'l jack

Oh, one other thing about the Baltic Birch. Were the raw birch La Scalas have just a birch veneer or was it 100% Baltic Birch?

Thanks Mustang guy. I'm thinking for the bottom panel I could get away without using the Baltic Birch and instead use something cheaper since it won't be seen anyways. Bob Crites told me to get a bottom panel or to seal up the bottom in some way to prevent the woofer from getting overstrained since it was meant to work in a sealed environment. The weather stripping will help that too. Thanks for the part number!

Thanks everyone on the worn screw removal advice! Let me work on that and then try to figure out the other one with the missing panel. I assume if I go get a piece of plywood cut 23x23 3/4x3/4 with regular plywood plus some weather stripping or gasket that would be a good start for replacing my missing panel?

Hi kids, I got my first pair of La Scala's (early-ish 80's) the other day...8 square feet subtracted from my already little living room well spent So... One of them has a bottom panel that is 23" x 23 3/4" x 3/4" plywood with screws in from the bottom whose heads are so worn i can't really get a screwdriver into them! Any idea if this panel is original? How can i remove the bottom with the screw heads worn down like that? The other one is plain missing the bottom panel. But there are screws with little metal tabs attached...no idea how those are used. I dont see extra screw holes for how a panel would screw in either. What do the original ones look like and how to they attach? Now Im not advocating everybody to go turn their LaScala's upside down....but if anyone's got a pic of the bottom I'd love to see it!
