Moderators dtel Posted December 23, 2011 Moderators Share Posted December 23, 2011 I didn't want to jump the other thread so I will ask here. Right now i have some old AA crossovers that are shot, one is even leaking. The speakers are "like" split LaScala tops, Bob's tweeter, k400 midrange. The bottoms are a single MWM/K43 bass bins for each top. These are in the workshop and wheel out into the yard to play outside, so medium and up volume but not crazy. Are the AA crossovers OK for this, I'm asking because at some point I will have to redo them anyway. It will have to be done on the cheap side no matter what I do. It sounds good but fixing the crossover has got to sound better, because of age and one even leaking. [:$] Quote Link to comment Share on other sites More sharing options...
ricktate Posted December 23, 2011 Share Posted December 23, 2011 HI,should not cost that much to replace the caps thats about all you need to do i think.Rick Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted December 23, 2011 Author Moderators Share Posted December 23, 2011 That's what I thought but not knowing anything about crossovers I wasn't sure if a change would be better. Thanks, I was going to just order the caps but thought I better ask first. This setup I use is really just like a LaScala with a k 43 bass driver as far as the crossover see's it, just the bass bin itself is different. It sounds like a LaScala with more bass.

colterphoto1 Posted December 24, 2011 Share Posted December 24, 2011 For your workshop uses, a refurbished A or AA should serve you well. The AA will have some tweeter protection through the zener diodes (those two metal thingies on the 2" wide piece of angle material. Moving to an AL3 or AL4 (depending on which midrange driver you are using) will give steeper crossover slopes to both midrange and tweeter, offering some more degree of driver protection at high volumes but you shouldn't need that so long as you're still using the D60 amp and not clipping it. If you try to shoot sound across the pond, we'll talk about some changes. Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted December 25, 2011 Author Moderators Share Posted December 25, 2011 I think that's plenty enough power for what it's used for, you can still set the speakers back 50' to 100' and have plenty of volume for what it's used for. I did try that HK 930 one day out there and it had a real nice sound but I wouldn't want to use it out there, I think the crown amp is tougher. One day I would like to hear a full set with the mid bass and top half that it was designed for, I have never heard one. Which is probably for the best really.

colterphoto1 Posted December 26, 2011 Share Posted December 26, 2011 Come on up here, there's a set always set up in my workshop : D All set up through Klispch's passive 4 way crossover powered with a 100 wpc JBL/Urie pro amp. Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted December 27, 2011 Author Moderators Share Posted December 27, 2011 I want to hear some but I would probably better off not hearing them, I would probably end up trying to make a midbass and adding other horns to the top.

colterphoto1 Posted December 28, 2011 Share Posted December 28, 2011 midbass would be an easy build - we could take measurements here. Quote Link to comment Share on other sites More sharing options...

My kinda guy That's funny I need a bigger place to keep them first. One problem with that is I couldn't use a regular crossover, would that then make it a 4 way.

kg4guy Posted January 19, 2012 Share Posted January 19, 2012 Here is the before and after of dtel's AA crossovers Quote Link to comment Share on other sites More sharing options...
kg4guy Posted January 19, 2012 Share Posted January 19, 2012 This is the after Solen caps with Dayton Film and Foil bypass caps boards sanded and repainted changed the autoformer and inductor back to silver new screws on terminal . Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted January 20, 2012 Share Posted January 20, 2012 are those new autoformers and barrier strip or did you clean up what was there? Wire brush on drill? small sander? what'd you use? Quote Link to comment Share on other sites More sharing options...
kg4guy Posted January 20, 2012 Share Posted January 20, 2012 Those are the original atoformers and barrier strip used little grade sand paper to get the oxidation off and some cleaner the inductor and autoformer had been painted black so I taped it off sanded it a little and sprayed it with silver paint. tried them out last night in my LSI's ,that I have ALK Jrs in ,and forgot how much I like the sound of the basic Klipsch networks.

Moderators dtel Posted January 20, 2012 Author Moderators Share Posted January 20, 2012 That looks great, it's really a wonder the old leaking caps still worked at all. I would guess they were really off from where they should be. I can't wait to hear what they sound like, I would think even with my old ears will hear a difference. kg4guy THANK YOU you have no idea how long I have been wanting to do this. I did electrical work for years BUT it was offshore and later on houses, I have no idea when it comes to something like this. I have a very slightly understanding of what caps do and an overall idea of the goal of a network but i have no idea what the other parts do in a network to get everything where it needs to be. Thank you Quote Link to comment Share on other sites More sharing options...

Guest " " Posted January 20, 2012 Share Posted January 20, 2012 looks good. star lock washers works wonders under the screws of the back row. they don't get moved much and oxidize over time. Quote Link to comment Share on other sites More sharing options...

Moderators dtel Posted January 20, 2012 Author Moderators Share Posted January 20, 2012 kg4guy, sorry but you have that turned completely around, your talking like a crazy person now. Thanks You , I had thought about new caps form a long time but would have also needed good instructions with pictures and soldering practice to not cause more damage than i was fixing. That's why it was put off for so long, but then you gave me a chance to get them fixed without worrying about ruining parts from not really knowing how to solder or wiring it wrong and blowing out a driver. Thank you, I have to say we have met some of the nicest people on this forum, where else do you meet people like this regularly, it's rare. Thank you [H] I have never seen anyone as fast as you, I got a message that you got them, and the next message is you were finished, a few hours later. [] You don't play around, and yes your right you did save them, they were hanging on by a thread for a long time and now they have new life, and they will be greatly appreciated for years.
