GaryA Posted March 10, 2002 Share Posted March 10, 2002 What do ALK crossovers run for La Scala's shipped? Do they make a huge difference? I have a pair of Scala's from 1984 and am thinking about the upgrade. Your input is appreciated. Thanks. Quote Link to comment Share on other sites More sharing options...
ShapeShifter Posted March 10, 2002 Share Posted March 10, 2002 Check out Al's web site below. He has contact info posted. He would have to give you a quote, because component parts cost constantly change, plus the number of orders also affect pricing.

edster00 Posted March 10, 2002 Share Posted March 10, 2002 Hi Gary, I have used Al's x-overs first in my Belles and then in my Khorns, IMHO they are worth the upgrade. ------------------ 2 Channel System: '78 Khorns w/ALK networks Welborne Labs Moondog 2A3 amps AES AE-3 Superpreamp DJH mods McIntosh MCD 7007 CD McIntosh MR-78 Tuner DIYCable Twisted Cross Connects DIYCable Superlatives (preamp/amp) DH Labs Silver Pulse interconnects (sources/preamp) f> s> Quote Link to comment Share on other sites More sharing options...
dubai2000 Posted March 10, 2002 Share Posted March 10, 2002 Gary, do you want a 'foreign' opinion? Yes, they are worth every cent and turn a great speaker into something outstanding! BTW: An additional bonus is the possibility to adjust the squawker level to your personal desire and amp/room suitability.

Dave in Nashville Posted March 10, 2002 Share Posted March 10, 2002 Gary: After I demonstrate my '77 "ALK" LaScalas and my guest is sitting there in stunned silence, I turn one of the speakers around and point to the crossover with its gleaming copper coils and colored caps. "That's the secret, " I whisper. Read the posts, buy the crossovers, enjoy your music! Dave Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted March 10, 2002 Share Posted March 10, 2002 Hi guys, Thanks for the good words. By the way, no more waiting list. I can deliver 'em for La Scalas in about a week! 8^) Al K Quote Link to comment Share on other sites More sharing options...

SOUNDJUNKIE Posted March 10, 2002 Share Posted March 10, 2002 Hey Al, I'm reading some really great things about these crossovers. I am wondering what I will find inside my Chorus II's that will be arriving next week. Anything worth upgrading or are the crossovers pretty good on these?

SOUNDJUNKIE Posted March 11, 2002 Share Posted March 11, 2002 OH GOODIE... I get to tweak some more. I can only imagine what I will look like to the FedEx guy, screwdriver in one hand, soldering iron and wbt solder in the other with slobber on my chin, the blank stare as if a deer caught in headlights...it ain't gonna be pretty.

mobile homeless Posted March 11, 2002 Share Posted March 11, 2002 Personally, if you have the older series of crossovers which employ oils for caps, I would hold tight and invest ducats elsewhere. These Xovers are very musical in my opinion; I have felt NO need to upgrade my Type B on these CW I. kh Quote Link to comment Share on other sites More sharing options...
SOUNDJUNKIE Posted March 11, 2002 Share Posted March 11, 2002 Hey MH, they are probably not the old style. My understanding is this pair is from the last year Klipsch sold the Chorus', the year they brought them back for one year only? Quote Link to comment Share on other sites More sharing options...
John Warren Posted March 11, 2002 Share Posted March 11, 2002 Gary- I have not heard AL K's networks. The components in Al K's networks are better than the factory. For LaScala you have either an AA or AL-3 network. If either of these networks were constructed from "similar" components, then a comparison would be reasonable. Again, I have not heard them but a few of the folks I communicate in NG's and other BBS's tell me that they are brighter in the mid. Some find that problematic. Remember too that Beraneck's Law is always enforced, it's subtle yet powerful. But overall, people do seem happy with the result. IMO, the mid squaker used by PWK is not a good reproducer and needs to be replaced so anything that makes it more pronounced is not good. Two pair of JBL 2123Js' can be had for $520 (tent sale). A pair on a Klipschorn used as direct radiators will produce similar efficiencies as the "autoformed" K55M but sound much better. Al publishes his network schematics on his site and even will help you build it. So that alone is a big plus if you want to learn. If you want to build your own AL-, AK- or AA- network I can send you a schematic. Quote Link to comment Share on other sites More sharing options...
mobile homeless Posted March 11, 2002 Share Posted March 11, 2002 Your are correct as far as the original poster. I was mainly talking to the others that might have a renewed interest that actually have the oil based caps. In the case of GaryA, it probably would be wise to either "roll his own" or save for the ALK. Obviously it is far cheaper to make your own and Al has been generous to aid here as well. kh Quote Link to comment Share on other sites More sharing options...
SOUNDJUNKIE Posted March 11, 2002 Share Posted March 11, 2002 John, are you saying that you think the mids on a Chorus II are not best served by replacing the crossover with something more efficient and if one were to do such a thing you would recommend replacing the mid driver with a JBL PRO part? I know that mdeneen uses Radianized 2470's....a good choice for the middriver on this thing? Any input would be helpful and MUCH appreciated on this matter.

Al Klappenberger Posted March 11, 2002 Share Posted March 11, 2002 Hi guys, First off, the question about using my networks in Heresys: The netrwork designed for the Cornwall will work in the Heresy with a few very minor changes. The network has a lot of expensive parts crammed very close together on the board, so it's rather expensive. I think too expensive compared to the price of the Heresys. I was intended for the Cornwall you know! I have never built a set for the Heresy and only got the first order for a set a little while ago. The prototype network I built for my Cornwall was modified and whent into a single Heresy, but that is the extent of my netwroks in Heresys! Anyhow, I recommend that Heresy owners simply build that for themsleves. That way all you have is about $200 - $250 parts cost. Unfortunately I don't have any network design for Chorus or Forte series speakers. My "A" sereis networks will sound brighter (my word is crisper) than the AA networks becuase of an inherent 3 dB loss in its tweeter filter. The squawker level is adjustable, so I don't see how it could be said it's to bright in the midrange! All you have to do in that case is move a plug! Al K.

mike stehr Posted March 11, 2002 Share Posted March 11, 2002 My '95 Chorus II's had some cheap 100 volt KSC brand electrolytics for the mid and bass. No oil caps in stock 1995 Chorus's. I just don't like the idea of electrolytics(Yuch!)in passive crossovers, so I made new ones. I kinda just wanted to replace the 'lytics alone. But after some questions, I went for the whole thing. $250 total. Now these crossovers are just stock with better replacement parts, and it was pretty much done by ear. I have never compared the two passives directly,(I used the autoformers in the old ones.) IMO these new passive crossovers seem to give the Chorus II's more guts. YMMV.
