Coytee Posted January 12, 2005 Share Posted January 12, 2005 My understanding is that the "A" X-over when comnpared to the "AA" version, has 3 (or perhaps 6??) db increase in it's energy. If someone has AA with ss and is experiencing sibilance, would not the conversion to A just make it much more annoying? Does the upgrade also somehow affect the world of sibilance? I'm just sitting here at work, bored to tears and had to think of something to ask. Quote Link to comment Share on other sites More sharing options...
3dzapper Posted January 12, 2005 Share Posted January 12, 2005 I have an AA with motor runs that is siblant and another that is not. I think the caps in the siblant one need "refreshing" or "retraining". The ALKs crossovers remove any worry I have over that though. If you think work can be boring, don't retire. Cold rain on top of slushy snow out there. I have no desire to go out and practice archery as I planned today. The drive and walk are already cleaned. I am "breaking in" my Sonic Image amp in the back room with resistors so I can listen to something besides the Allman Brothers over and over. The forum is slow. The high point of my day today will have to be my nap! Rick Quote Link to comment Share on other sites More sharing options...
Coytee Posted January 12, 2005 Author Share Posted January 12, 2005 what does "with motor runs" mean? zzzzzzzzzzzzzzzzzzzzzz wha?? who's asleep??? Quote Link to comment Share on other sites More sharing options...
3dzapper Posted January 12, 2005 Share Posted January 12, 2005 Those big silver cans in the AA. Those caps were initially intended for phasing large electric motors like on an air compressor. They really made good crossover caps in their time as they are film and paper in oil construction. Rick Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted January 12, 2005 Share Posted January 12, 2005 The tweeter filter does not casue sibalance as some have suggested. It is something that is actually recorded on CDs. You can even hear it with headphones that have no "network"! If it's there you want to hear it. Make your speaker have a flat frequency response and if the simalance bothers you, turn down the trebble control! The AA network losses 3 dB becasue that energy goes into the squawker and is wasted. The squawker runs from 400 Hz up! If you are going to waste high frequency energy do it by some means you can control and adjustr, like an L pad or the pre-amp trebble control! Al K.

Deang Posted January 12, 2005 Share Posted January 12, 2005 "If someone has AA with ss and is experiencing sibilance, would not the conversion to A just make it much more annoying?" No, because any sibilance comes primarily from the midrange. If you're running SS, stay with the AA's. Depending on their age, you might want to consider replacing the capacitors. Do you have the K-55-V or the K-55-M? Quote Link to comment Share on other sites More sharing options...
yaffstone Posted January 12, 2005 Share Posted January 12, 2005 What's simalance? How do you know if you've got it? Would ear plugs have protected you from it? Only the first question is serious. What's simalance? Quote Link to comment Share on other sites More sharing options...

yaffstone Posted January 12, 2005 Share Posted January 12, 2005 DeanG, They generally don't spit on or at me. I try to be nice so that won't happen. Quote Link to comment Share on other sites More sharing options...
Coytee Posted January 12, 2005 Author Share Posted January 12, 2005 Dean: Not sure which I've got. I got my LaScalas about 1980 and they have the AA, that's all I know for sure. they're currently buried behind some "stuff" as I'm moving things about in the basement so I can start FINISHING it, and put them in their new homes, along with their big Brothers Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted January 12, 2005 Share Posted January 12, 2005 Dean is right, sibalance does come from the squawker too! If you want examples, listen to Sarah Briteman or Wynona Ryder. They both got a big case of it! I got a frined whos wife sings in the quior of a major symphony orchestra. They have to take special care to control it. They refer to it as "the snake"! Al K.

J.4knee Posted January 13, 2005 Share Posted January 13, 2005 If you really want to hear it in a speaker listen to circa 1980's Infinity Reference Standards. Quite possibly the most annoying ssssst sound I have ever heard in any speaker. I had a buddy had a set and he tried 3 or 4 preamp/amp combos and multiple different CD players and no matter what the recording was, the high end just went sssst all the time. The cymbals in the percussion section were unbearable. He eventually sold them and bought POLK SDA 1.5's. I tried to talk him into Klipsch but he professed that a strong coloration existed in any horn driver that unacceptably altered the true nature of the sound. He was a sonar tech in the Navy and I think he was pinged a few times to many. Quote Link to comment Share on other sites More sharing options...
