ALK universal crossover


Recommended Posts

If you still have the cornscala's I'd just temporarily move the ALK's to the khorns to hear.  Doesn't Al offer those at a couple of different crossover points (400, 500...)?   Not sure you want to push the bass bin of the Khorn to 500 though?

Big room, seat far back, playing LOUD (80-85db or louder) and I'd start thinking about ALK's steeper slopes.   I prefer AA's for overall listening.  It isn't like things fall apart when things get loud.  I'd spend my money on AA's with Jupiters.

I sent you a private message,the ALK cornscalla crossovers work well in my Klipschorns.I also have the VTK-400 by Volti.I use a Line Magnetic 219 amp,so l am somewhat familiar with your amp.

 

 

Yes, thanks for that message. I assume you prefer the Volti to the ALK?

Better than alk not really,I like you wanted to improve the sound of my Klipschorns and went with the ALK in the beginning because of cost.I bought from Al the fastrac tweeter and the entry level crossovers and could tell a big difference when I swapped out the tweeters and crossovers and a pair of VTK-400 popped  up on this site and I bought them made the switch and it took me a couple of days of changing the clips on the crossovers to make a difference.I have since swapped back to the ALK's,my system to me has better bass with ALK's.I have no plans on selling the VTK-400's and if I can ever find a deal on some Volti horns,I would try his crossovers with that setup.What type of tubes are you using with your amp.

Yes, to the tweeter question.If you get a chance try Telefunken made in west Germany 12ax7's,you can usually pick up a pair for around 120-130.00 a pair.I have used RCA,GE,Baldwin and Mullards and like the Telefunken's the best.

ALK all the way
I’ve used them in k-horns. Cornwalls and A few of my own built 3 way speakers either a sealed , ported and of all things a tuba 3 way speaker and it worked a hole lot better then I thought it would. It’s a pretty versatile
Crossover
What I like about his crossovers is that he has been doing this for more years then anyone else around. And to tell you the truth
More then one of the other guys buy his crossovers and will change out 1 or 2 caps with something that’s a different color and brand and say that’s it’s their design and these yahoos don’t even have a scope or any other bench test gear. And they call themselves a electrical engineer or a audio engineer
Just my two cents.

Multiple choices... 

a couple for Jupiters:

or

For less money Deang suggested Audiocap Thetas and Musicaps  a while back:

There also Crites who sells Sonicap upgrade kits.  He is great to work with.  Sonicaps are a bit bright to my ears.

 

Other fun choices:

Jensens aluminum foil paper in oil

Vcaps oimp

If you have a really old pair of AA's, ANYTHING will sound better. Any new pair of networks, regardless of design, will restore the high frequencies -- which will always sound better than a pair of 40+ year old networks.

 

Most have never heard a new pair of AA's, with film and foil, or oil filled capacitors. This means the majority of comparisons are typically ALK CornScalaWalls vs. AA's with worn out caps. I've also worked on plenty where the windings have come loose off of the core on the autotransformer.

 

The Universal is convenient if you like to play with different drivers and horns, and have to rebalance the sound. Other than that, a quality AA build will kick the shit out of it.
