AnalOg Posted December 27, 2007 Share Posted December 27, 2007 Hi all, I'm in search of some ALK's for my La Scala's. I'm in the process of pieceing my system back together and wish I never sold them at this point. What a difference in transient response and attack they bring to the table. If someone has a set they are interested in selling let me know. Tom Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted December 27, 2007 Share Posted December 27, 2007 Why not just build a set? Quote Link to comment Share on other sites More sharing options...
AnalOg Posted December 27, 2007 Author Share Posted December 27, 2007 Tom, I am considering building them also, I would perfer to buy a set which have the Hovland as apose too the Kimber caps that now come in the kit. I could be splitting hairs here and there may not be a difference but why chance it if I can buy a set that I'm familiar with its sonic qualities.

Deang Posted December 27, 2007 Share Posted December 27, 2007 That tweeter circuit is too hot as it is -- if I was building them for me I would use Auricaps or V-caps. I wouldn't bother with the kit, just buy the parts yourself. Quote Link to comment Share on other sites More sharing options...
AlanWinslow Posted December 27, 2007 Share Posted December 27, 2007 Is there a post or website with a list of the parts and source to purchase from? Thanks Quote Link to comment Share on other sites More sharing options...

Dean, I started looking up the parts to build this and some of the components like the coils, autoformers and terminal strips I couldn't find. Is there a one shop source for all the components? I'm not sure I understand what your refering to when you say that tweeter circuit is to hot an to use Auricaps or V-caps, are you saying to use them as a sonic preference or that will help tame the tweeter issue.

Tom Mobley Posted December 28, 2007 Share Posted December 28, 2007 I have a set of ALK universals that I built sveral years ago with all the correct parts including the Hovlands. I'd be willing to sell them for a good offer. They're not cheap. They're built on finished Oak boards, not particle board. Quote Link to comment Share on other sites More sharing options...

Guest " " Posted December 30, 2007 Share Posted December 30, 2007 "I thought the Universal networks had attenuation for the mids and tweets? " Almost....the cornwall versions have the tweeter and mid driver wired off the autoformer....so you could move them around to suit your taste...but the universals only has the mid driver off the autoformer so moving the taps around won't level change the tweeter..

Deang Posted December 31, 2007 Share Posted December 31, 2007 "...the cornwall versions have the tweeter and mid driver wired off the autoformer....so you could move them around to suit your taste..." No you can't, it's a fixed tap design. We've been down this road several times in the past, please quit telling people that. Quote Link to comment Share on other sites More sharing options...

No you can't, it's a fixed tap design. We've been down this road several times in the past, please quit telling people that. It's fixed until you change the value of "R" for the swamping resistor. Next time I'll say "I have " instead of "You can" Quote Link to comment Share on other sites More sharing options...
Deang Posted January 1, 2008 Share Posted January 1, 2008 I don't care what you do with the resistors, it's a still a fixed tap design -- you can't adjust the attenuation on the fly like you can with the Universal which uses a floating ground. The Cornwall ALK has two swamping resistors. There is a 5.6 in parallel with the K-55, which swamps the driver down to 4 ohms, then a reflected impedance of 16 ohms (4x/ tap 3). Another 5.6 across taps 5 and 0 to swamp back to 4 ohms. The network is a diplexer design with matching high pass and low pass sections (4 ohms). If you change one resistor, you have to change the other -- and adjust the cap and coil values. At that point you have a different network. Maybe some details on what you did exactly would be helpful, I'm always ready to learn something new. Quote Link to comment Share on other sites More sharing options...
DrWho Posted January 2, 2008 Share Posted January 2, 2008 you can't adjust the attenuation on the fly like you can with the Universal which uses a floating ground.Well you can if you don't care about screwing up other things [] Quote Link to comment Share on other sites More sharing options...
