I asked the same question. That's what I have too, so what is best? Honestly would really like to know.

So ALK, Crites and now JEM are all on record saying the AL crossover basically sucks. If I don't want to change out the K-55M the only solution is the AL-3? JEM is saying you shouldn't just go with the AA crossover, but Crites says his AA or AL-3 are what he recommends. Does his AA account for the K-55M?

"Klipsch Approved" updates apparently don't apply to the AL crossover. I checked with JEM by email a couple days ago regarding what can be done to improve the AL's in my La Scalas and he agrees there is no simple fix. Here is his reply regarding the AL's... Next the AL network in your LaScalas. Well, this network really isn’t the best. The midrange driver attenuation is off by 2db. Then there is the issue of the notch filters. That is a whole discussion by itself so I will leave that alone at this time. This was all corrected in the AL3 network but to modify the AL to AL3 is expensive and would require parts no longer offered by Klipsch. They would have to be sourced from other vendors and I don’t get involved with parts other than what the factory can provide. This is the only way to keep a repaired speaker a genuine Klipsch product. If you want to keep your LaScalas performing as-built, I can provide the Klipsch replacement caps. However, this doesn’t address the problems with the AL network. You can’t change to a AA network unless you change the midrange drivers from the K-55M to the K-55V. The M and V have different sensitivities and therefore need specific networks to operate properly. So, you have two choices available that will still give you a genuine Klipsch LaScala other than just leaving them alone. First you can back-date the LaScalas by switching to AA networks and K-55V midrange drivers. I would recommend finding a good set of solder terminal K-55Vs. This would place your LaScalas in the ’81 to ’82 vintage. 1981 and ’82 vintage Klipsch speakers sounded extremely good. The only reason Klipsch changed things in the mid ‘80s is because the manufacturer of the midrange driver had some quality control problems and ceased production of it. Electrovoice made the K-55M but due to variations in design, a new crossover network was needed for this driver. The AL network was the result. The other option is up-date to the LaScala II. This is probably the most expensive route but it would get you essentially a 2018 speaker. You would need to change the crossover network, midrange driver and tweeter. Unfortunately, all that would be left from your ’86 speakers is the cabinet and woofer.

That is one comprehensive list, thank you. Also worries me because I think I'm in over my head even attempting most of what you suggest. I'm gonna take a peek inside again but I think I'm going to have to get it looked at when all is said and done. Guess I don't mind spending a few bucks if it can be fixed.

I have a HK 730, was getting some noise and scratchiness in the volume so I cleaned it with Deoxit, also sprayed the other knobs and in and around the RCA inputs. Worked great for awhile then would get random distortion as volume would rise. Sprayed again (not too much) and moved my speaker connections to the B inputs and it again worked great and sounded awesome. Now the distortion has returned when the volume goes up, not crazy loud but moderately loud. The distortion can be in either speaker. Do I need a certain part, is it something I can do myself? Do I need to spray something I haven't tried yet? Love to hear some thoughts if you guys have any ideas. I love this receiver and plan to keep it forever. Thanks John

Sold

Bought it new with the optional AptX Bluetooth module, both pieces were $350. Still have the original double box that Emotiva uses which is very sturdy, so shipping could be a possibility if you wanted to pay for that. No damage or scratches, works like new. Asking $200 on CL, $175 for forum members. Just listed it on Denver Craigslist. https://denver.craigslist.org/ele/d/aurora-emotiva-basx-pt-100-preamplifier/7247795842.html

I've been using a Cornwall I for a center between my Khorns but to do that I had to split up the pair so one them has just been sitting collecting dust. I figured this Chorus II should be as good or better movies. I tried it briefly yesterday by watching The Patriot, the cannons, bombs and dialogue seemed awesome lots of depth and presence, think it does better than the Cornwall for that purpose. Very happy so far.

Costco near me is selling them for $89.99, great deal if anyone needs it. Mine are still running strong for over 10 years.

Gone.......Just got back home with it, it's in like new condition. Super nice guy he helped me out and gave me a few more bucks off.

I'd pass for that price, had a couple pairs and wasn't all that impressed. Now for around 300 I think you'd be happy.

What JBL model did you get and what did you pay?

???? What kinda post is this? you did the same kinda thing on another one.....

Sorry yea I guess he said he'd use acoustic bass traps to create false corners, in my mind that still sounds like a variation from the version built by PWK. Maybe that'd be fine.

I can't see how Khorns would work at all in that room, you need corners or you'll need to build false corners. It won't sound right if they aren't used the way they are designed to be used.

Klipschorn = Toe In 45 degrees...I think a little bit of thought went into that.

Maybe 950-1200 depending on the finish and of course the condition.

Wow Quartets are really going for that kind of money?! Had a couple pairs in the past and wasn't overly impressed especially for that kind of money. Make sure you hear them first before buying.

JBL is selling factory refurbished 530's for $279.00 right now, bought a pair today...2 day shipping included for free.

What is the Make and Model of the 15" powered sub? More pics?

Could be as simple as that, they should destroy those little JBL's with no problem.

Considering they are still worth about that much and you could get almost all your money back you really spent nothing...just tied your money up for a bit.

Love to hear a review and how you feel about the change. Been contemplating the same move, I have LS with AL crossovers and wonder if the difference is dramatic enough to spend the money. Let's hear what you think. Thanks John

That info was here somewhere at one time...I'd like to know too.

I used one in my THT LP, dimmensions of the cabinet is 18"x18"x60". BFM plans, it sounds awesome.
