Porn_Star Posted September 7, 2014 Share Posted September 7, 2014 i have 2 matching la scalas, and 1 center that doesnt match. they matching ones are 1992 and the crossovers look like a mess. the matching one has a bad woofer, and 2 peizo tweets that i will bring replace with klipsch k77m tweets, the subs are k33, and i will try my best to replace or recone with the same sub. the squakers are k55, they are not the ones that look shielded, but rather with the raw magnet showing. the crossover are al-3 i do not know the exact year of the black la scala but the crossover is an al. what do you recomend? i wil be using these as a center, left and right. of course the center will be the black one with the al xo. i will use these for music as well, but not as much as i will also have my bedroom setup. this is part of a new theater build. as most folks, i am trying to be as economical as possible to save money for the rest of the build. i am considering waiting till i am done with the build, so i wont be so anxious to buy more parts and may be willing to spend more money on getting a better xo build. but i seriously do not want to put any of my drivers at risk because of xo failure if you think these need to be changed asap. also, do you recomend getting a al-3 for the black scala? that way they will all be matching? i know that the al xo looks decent on the outside compared to the al-3, but i am sure those caps have had some mileage on them! thanks for the info. i can solder and whatnot, so if you recomend just refreshing the caps, i can definitely change them with your kits you offer.

Marvel Posted September 7, 2014 Share Posted September 7, 2014 A couple of things come to mind. 1. How loudly do you listen to your music? If you listen around 85-90db, with occasional peaks going a bit over, a type A or AA or derivative would sound really good and not be too expensive. How much are you willing to end up spending on the crossovers? Having them all match is, of course the best thing. 2. Could you build some yourself? I had AL crossovers in mine, and replaced with a pair designed by forum member John Albright. They are called a DHA2, as he designed them for his brother. The would be fairly inexpensive, and sound really good for lower power use, and are especially good with tube amps as they present a more constant load to the amps. DeanG has constant impedance crossovers as well, he uses premium parts in his and they sound extremely good. I tried a pair of his that he sent around on his Crossover Roadshow. I consider them the best of the best. They not only sound fantastic, they are works of art. If you want to save up your money first, but want them to be passable, you could just replace the caps in the ones you have but wire them all to be the same. Here you could buy the grade of cap to suit your budget (knowing better caps get better results). Cleaning the ones you have might help. All screws should be loosened and re-tightened. Disconnect and reconnect the drivers, too. Get some Caig De-Oxit and clean away. The ones you have really, really need the caps changed (on all three crossovers). Dean Wescott has prices listed on his website, as do Al Klappenberger and Bob Crites. Take your pick or roll your own. You can pick up a new K33 from Klipsch at a reasonable price, or possibly find one in good shape from a forum member. Bruce 1 Quote Link to comment Share on other sites More sharing options...
Porn_Star Posted September 7, 2014 Author Share Posted September 7, 2014 1. Very loud. To give you an example, I have rf7ii's on a nu4-6000 that I listen to just before clipping. And that still isn't loud enough! After reading for hours, I tthink I want to change the al to an al-3 for the tweeter protection. 2. Yes. I can solder and all that good stuff. But I do not know much about crossovers. I understand the function, but placement and all I would get wrong without being told where to put what. These are going to be used on a home theater setup. I will power them with an inuke nu4-6000. I know it's overkill, but I want as loud as possible. As far as price wise. Like most folks I want the best for cheap. I was looking around and was considering spending upwards of 500 on all 3. To include a new one to replace the al. I really would like tweeter protection as mentioned earlier.

Porn_Star Posted September 7, 2014 Author Share Posted September 7, 2014 I really would like tweeter protection as mentioned earlier. While a different approach, both the AL and AL-3 have tweeter protection. AL AL-3 Oh sweet! I did not know this. Then why the recommendation to use mainly with 80-90 db of playback?

Deang Posted September 7, 2014 Share Posted September 7, 2014 The AA also had tweeter protection. The answer might be a better tweeter. Cheap parts at 120dB will drill a hole into your ears. Enjoy. Quote Link to comment Share on other sites More sharing options...

Deang Posted September 7, 2014 Share Posted September 7, 2014 Bruce, I add a low pass to the K-55 in the AA and build with parts that really take the edge off. I can also drop down a tap and add a resistor in parallel which really works well for jacking on the volume. I prefer my modified AAs over all networks.

Deang Posted September 7, 2014 Share Posted September 7, 2014 That's fine. Just make sure you have the Zener Diodes in whatever network you decide upon. Quote Link to comment Share on other sites More sharing options...
Porn_Star Posted September 7, 2014 Author Share Posted September 7, 2014 That's fine. Just make sure you have the Zener Diodes in whatever network you decide upon. How much will that run? Do you suggest replacing the al-3 because they look like crap? Shoot me a price! Quote Link to comment Share on other sites More sharing options...
Schu Posted September 7, 2014 Share Posted September 7, 2014 Like most, pron, they prefer to do business off site if they are conducting transactions. Why don't you write him directly... dean is a pleasure to work with and he really needs to talk with you in person. Quote Link to comment Share on other sites More sharing options...
Quiet_Hollow Posted September 7, 2014 Share Posted September 7, 2014 Do you suggest replacing the al-3 because they look like crap? I'll leave the filter network suggestions to Dean, but as far as "looks" are concerned, they really don't mean anything where the integrity of the electronics are concerned. I'd bet my left nut that any negative sound issues you are experiencing at the moment have more to do with the combination of that iNuke amp, lack of any EQ, a gain staging issue, and using MP3 or AAC encoded source material. IME, a properly maintained and fucntioning AL-3 La Scala, driven with the right gear, has no "edge" to speak of. Quote Link to comment Share on other sites More sharing options...

I kinda figured that, but as I was searching for this info I couldn't find much about it. I figured I would try and make some of the differences, along with his opinion of a xo that looks like this, a little more public. Quote Link to comment Share on other sites More sharing options...

I was listening to lossless, along with bluerays. I understand the whole "crap in-crap out" concept. I would say most of my problem lies in the piezo tweeter, blown sub, and old caps. All of which I am trying to sort though at once. I will most likely box up my xo's and let him sort through their functionality as I don't know anything compared to his experience.

Now that you know he likes them loud... there's progress. I prefer my modified AAs over all networks. And I know how you like to listen. I am pretty sure that's what I would put in the pair I have left, but I am going to redo my DHA2s once I get that far. P_S needs to give you a call.

Deang Posted September 8, 2014 Share Posted September 8, 2014 I'm a custom builder. I prefer to build from the ground up, using the best parts available. I'm mostly interested in delivering the best sound possible. The large Heritage loudspeakers are prone to bleeding the ears out, and seriously, I will never understand how some of you can stand to listen to them without good films and a tweak or two. I'm "expensive" because my builds are time consuming and my parts cost a lot. I handle PCB work a little differently. Rarely does someone want to invest this kind of money into a pair of loudspeakers they got off of eBay for peanuts -- so I use different parts, which changes the pricing structure. I think many of you have disabled the signature feature, and so you don't see my email and website addresses. I know this because too often I see questions that I address on my site. I'm buried. If I didn't have a half dozen builds ahead of you, I would take on this work and do the recap. Seriously, you need to send all of this stuff to Bob Crites. The downside is that because of the volumes you listen at -- I think you're going to be disappointed (unless you've already destroyed your hearing, in which case it won't matter). This opinion has nothing to do with the quality of the work that comes out of Bob's shop. I don't like the AL/AK series of networks, and if I was doing the work, I would put you in a choke hold until you tapped out and did it right. I see you shoot a Glock. I guess that means you're also saving up for a 1911. 1 Quote Link to comment Share on other sites More sharing options...
