    Horn mods

    in Technical/Restorations

    Posted

    I saw in a DIY forum where people were wrapping the exterior of the horns with a white cloth like substance... I am assuming this was to dampen the resonance of the horns. Has anyone tried this on the Klipsch Horns? I was thinking maybe some dynamat.

    LaScala problem

    in Technical/Restorations

    Posted · Edited by ellisr63

    Ron,

    I know you saw these on the AK site. The LS used by the Rodgers Organ Co. was pretty much a stock LaScala with their amp installed opposite the stock Klipsch crossover. Unless they bypassed the crossover to just drive the woofer, the crossover would still have been used, even if they used it just for the 'bass'. They wouldn't have gotten deep bass out of it anyway.

    If it has the old oil filled caps like in the pic, I would replace them and dispose of the caps properly. They have PCBs in them.

    Here's a pic of one with the top removed (older style LS)

    Bruce.

    Thanks Bruce, I just got home with the 3rd LaScala... This one was in much better condition than my other 2 that I got last week. This one even has the little envelope still attached to the back. My friend and I pulled the top off and removed the amp and rewired the crossover to work. I am going to do the caps to the other 2 and then I will do this one. It appears that you can get a better deal on the Rodgers LaScalas than a normal LaScala. I paid $400 for this one on eBay, and I could have gotten it for less but I was afraid that someone might get into a bidding war with me so I did the Buy Now price. I am going to keep my eye out for more... Who knows maybe I will end up with a 9.1 Lascala setup! I am currently trying to sell my Paradigms to fund another pair of LaScalas.

    Another question...

    I am picking up a 3rd LaScala in the morning. This one has a Rodgers amp built in for a powering the bass. From what I was told, since 2006 it has been used only for bass. Will the caps deteriorate due to age or only by use?

    How can I tell if the caps are bad or not? Is there a measurement for spec on the caps?

    Klipschorn 70's Vs 80's

    in 2-Channel Home Audio

    Posted

    Well i would like the 70s more but if you can get 80s model go for it. I did find air leak in my 70s model in the back woofer air chamber but was fixed pretty easy. Maybe they all have little air leak from glue cracking, not sure no one else has checked thiers. I can tell you how to check it. Rick

    I have some LaScalas made in 1978... How do I check them for leaks please?

    There was (is) a guy selling those wooden horns on Ebay that looked similar to these. Are they similar?

    Tame the your Klipschorn, La Scala or Belle with our new direct replacement wood waveguides!
    Every horn is precisely cut with a CNC and completely hand finished then assembled right here in Maine.
    Waveguide horns are used in most studio monitors and noted for they’re linear response, openness and lack of high frequency beaming. The waveguide gives you all the sound quality of a horn without the flaws and coloration.
    We use the American made eminence apt-50 and can make these horns out of any wood (some woods may add extra cost). Our goal is to use mostly upcycled wood to reduce shop waste and save the extra cutting of trees, also reducing the cost to you!!
    What to expect.. The k-77 is a great tweeter but has always been a little hot in my opinion, almost a little harsh and over bearing. I love how these waveguides smooth the high end without losing presences. Also there is a better balance between the mid range and high frequency with less separation between drivers.
    I would be very unhappy if I bought a tweeter from someone online and find out it was not what I was looking for. If you are unhappy with your order you can return for a full refund within 7 days of receiving it. So, the risk is mine, just send it back in perfect condition I’ll refund your money! Shipping is not refunded.
    Thank you for taking the time to view are horns!

    That is for a pair including the drivers? SAeems like a good deal.

    Crossover replacement

    Wow, thanks TK, I think we may have a winner! So now, it is new improved crossovers, a tube amp, and an improved mid range, say a Fastrac LaScala, this is going to take me a little while, and I will be looking into the bass bin beefup. Muel, the Caps from 89 are still working, just seems to take more juice to get sound from the speakers, one is far worse than the other. I bought these speakers when I was stationed at RAF Bentwaters in the UK, had them in a 12x12 dorm room, for a while I had the La Scalas, and a set of Cerwin Vega CD-90s, the Cerwin Vegas were too much bass for me. I ran everything back then with a Yamaha C-65/M-65 preamp/amp setup, now I am using a Sony surround sound system in 2ch mode.

    Small world... I bought my first pair of LaScallas from RAF Lakenheath in 1979. :)

    LaScala problem

    I went to test the speakers with a 9v battery and discovered the midrange screws were loose. I tested the tweeter and midrange and then re hooked them up... Checking all the screws to make sure they were tight and then played some music. Both channels are working fine again... apparently the seller had disconnected the mid and tweeter at one time and hadn't tightened them down properly. I am glad I didn't have a blown speaker! Next week I will get the new caps installed.... I have never had to solder before is this something I should attempt or should I get it soldered for me? I can do mechanical work but I have never tried soldering, but years ago I did some welding... brazing, mig, and ARC.

    I just picked up a pair of 1978 vintage LaScalas a few days ago... They sounded good but I was told due to the age I should buy new caps. So I ordered some new Poly caps (they will be here next week). I have been listening to music and tv on them for a couple of days now, and today when I turned them on this morning I noticed the left channel is not working properly. I put my ear by the tweeter and it has a faint output (sort of a crackly sound), the midrange has no output at all, and the woofer is fine ( not sure if that is correct or not but there was bass coming out). How can I find out if the tweeter, midrange, or woofer have failed or pinpoint the problem? I have not been listening to them loud other than 1 time when I turned them up and I heard the audio switch the focus to the other channel and then go back to normal. I am hoping it is in the crossover but I don't know how to check it out? I remember seeing speakers be tested in a car stereo place with a 9v battery... Would that be a good way to test the tweeter and midrange?

    Speaker Wire Question

    in Technical/Restorations

    Posted

    Hello. I am repositioning my speakers and need longer wire runs.

    http://www.parts-express.com/cat/speaker-wire/1894 has 4 categories:

    1) Hi-Fi Speaker Wire, 2) Zip Cord, 3) Jacketed Speaker Cable, and 4) Flat Speaker Wire.

    In what circumstances any one of these types may be prefered over the others.

    Thanks,

    Serge

    I'd say the Hi-Fi would be more expensive than zip, but probably no better at doing the job. The jacketed would offer more protection perhaps. The flat is more decorative. I really don't know why they would divide speaker cables like this. Frankly, you should be looking at monoprice for cables. They make better sense and are less expensive. If you are putting the wires in walls, you need CL rated speaker wire.

    I buy most of my wires from Monoprice too.
