I'm looking for information on the balancing networks or crossovers on the heritage speakers, Specifically what I'm looking to learn about is the differences between AA crossovers and the AL crossovers. I have a friend who's finally sourced out a pair of Lascalas for himself and these look to be circa 80's and they have AA crossovers. I'd like to get some insight, opinions, and more knowledge on the crossovers, so I'll pose some questions I have in point form, thanks in advance. When were AA crossovers used (from 1963 to ?) Where the AA simply replaced with AL's ? Is theses crossovers interchangeable in the Lascalas or are the AL's built for a certain model with specific drivers? What is the value and worth for these two networks in good working condition? Is there any reason to continue using the original networks, and what to look for when inspecting these? Is there any harm or potential for problems, by giving my friend my unused AL's to 'try out' ?? Thanks!

Well I have solved the heat problem. Reflectex, I bought a roll from Home depot and it is essentially bubble wrap with a tinfoil membrane on either side, so its flexible and easy to work with. In fact, it was perfectly wide enough that I need only cut to length.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> I spent Saturday doing some tests, and I am actually quite surprised how well it works, I went so far as to put the speaker beside the heater with a hand width apart and no problems at all with heat, NONE! Its cool to the touch, so that is huge for my living situation and me. I would never have convinced the wife that we could forgo the room heater, so this works jus fine by me. I keep the soundstage intact and can enjoy all the room heating benefits without cooking my lascala! Thanks for the responses I also messed around with toe in with some interesting results, however, now, based on the above thread response, I will pull them out from the wall and see how that sounds. I do not have a sub-woofer for them, I do have and use a PCA or Phase-coupled activator, which restores low-end frequency by way of harmonics and it works pretty well for the listening volumes I use. Anyone here explain what happens to the signal below the speakers rated frequency response? The woofer itself is 15 and when it reaches it limit (power handling) what happens to it? Does it behave like a conventional driver; does it reach its excursion limit? I also wonder if at 100 watts, which would be LOUD, does the woofer sound like it can keep up? I just havent pushed it myself, and doubt I ever will, so Id like to hear fro the community there own experiences. The PCA is made by a company Audio Control and works on any speakers, and while it can tax smaller speakers/drivers, It can drive woofers to their limit pretty quickly

So far I have managed to mitigate the problem with heat by physically moving the speaker away from heat source. I like the sound of 'toe-in' but not the look of the speakers, the size of the speaker itself tends to exaggerate the appearance and it just doesn't look aesthetically pleasing. The sound seemed to benefit, but not by much, when comparing to a conventional floor stander. I think for the most part they will reside flush against the wall and when listening, I can always adjust for more toe-in. I will check home depot today and see what they have available and suitable as a heat shield... Thanks for the responses and the warm welcome.

Hi Everyone, I'm a new member and joined the forums today! I'm a recent owner of Klipsch Lascala's in black and I also consider myself to be well seasoned in my audio hobby. I have had many systems and tried many different solid state pieces of gear and especially speakers. I just recently purchased my Lascala and have been enjoying them since the moment I heard them. Prior to this purchase my only exposure to Klipsch was there new RF line of speakers and some computer audio systems, I had never seen Klipsch Lascala's until last year and never heard them until I auditioned the same pair, needless to say I purchased them and brought em home. As I was loading them into my van, I remarked that they were a little bigger than I remembered and hoped they'd be a good fit once I moved them into their new home. After Installed them I sat back and thought Wow, pretty big, defiantly notice them when I walk into room. My wife thought I had fallen off my rocker and asked me "what were you thinking??" and I said, "Kinda big huh?" to which she sarcastically snapped back "ahhh, ya' think!?" Well since having them over the last few months, she very uncharacteristically remarked out-of-the-blue one day "these sound good". So I jumped on the chance to engage her in a conversation about them, and from my probing questions, I extrapolated that of all the speakers she has heard in my system, the Lascala's sound the best to her. So I was happy getting her 'stamp of approval' and that she confirmed what I was thinking myself. Now they can rest easy and start to assimilate into the home. So, while I have little wiggle room for placement (toe in, shift side to side by about 6") I have some questions I'd like to pose to the community here: One one side I have a gas-space-heater and am concerned about how close, and how hot the side of one of the speakers could get if left unprotected. I did some placement tests(close) and then felt the speaker's side after several hours, and while it was not burst into flame hot, it was initially hot to the touch.When I checked the inside of cabinet by sticking hand through the open hand it was fine (Thick playwood)Here's my question: The speakers side closest to heater could be protected using what? I thought about a reflective thin sheet of insulation? Tinfoil? Is there any chance of the wood getting too hot and warping? Any suggestions would help. Second question: I read that Klipsch love corners, and that they bloom in corners, of course this is against all the conventional wisdom about speaker placement, and with one of my potential corners for placement being taken up with the heater, that leaves only 1 corner. As it is, it's pulled out of corner so to match the other channel. Corner loading for me just didn't sound right for me, but is it something I should give more of chance to? Third question: What do I do with the stock crossovers? These came with ALK crossovers and I can't see any reason to change them out. Fourth question: With respect to toe-in, these bad boys are so big, that toe in requires them to move out from the walls, so what's the experience from owners of these, flush and flat for positioning or toe-in and by how much? Thanks for reading, and look forward to reading your responses.
