Delicious2 Posted April 15, 2012 Share Posted April 15, 2012 Looking to upgrade AK-2 crossover in 1990 Khorns with Dave's Eliptrac midhorn. Crites? ALK universal? ALK ES? Volti? I listen to classical and jazz at low volumes primarily in the background and a wide variety of jazz, dance, pop, and progressive rock at moderate levels in the sweet spot.

Delicious2 Posted April 15, 2012 Author Share Posted April 15, 2012 14x28 room open at right end is not really wide enough. I've angled in and down the top hats to compensate. Quote Link to comment Share on other sites More sharing options...
Delicious2 Posted April 15, 2012 Author Share Posted April 15, 2012 Right angled in. Quote Link to comment Share on other sites More sharing options...

Delicious2 Posted April 17, 2012 Author Share Posted April 17, 2012 Bump. No experiences with Eliptrac? No crossover prefs? Quote Link to comment Share on other sites More sharing options...
Chris A Posted April 17, 2012 Share Posted April 17, 2012 Try this one: Of course, you'll need a couple more amps, but I believe that the sound will be outstanding. Here is a thread on Khorn settings that would be very useful to have as a point of departure. Chris [] Quote Link to comment Share on other sites More sharing options...
Delicious2 Posted April 17, 2012 Author Share Posted April 17, 2012 thanks for the reply Chris and the link. I had read through that thread and other active crossover threads awhile back. I heard an active Khorn system briefly done by Greg of Volti a couple of years ago with a Behringer 2496 I have fooled a bit with a MiniDSP for my sub but don't think I'm ready for full active. Probably just a passive that's adjustable? Quote Link to comment Share on other sites More sharing options...
Johnny's Jill Posted April 18, 2012 Share Posted April 18, 2012 I heard Daves Khorns with the AP12-350 and the ES-5800, and was blown away... Great combo, I think it bested his Universals. Craig 73 Quote Link to comment Share on other sites More sharing options...
Deang Posted April 25, 2012 Share Posted April 25, 2012 The best network for the way and what you listen too is a simple first order type, similiar to the old Klipsch Type A. It doesn't need to be adjustable, you just need to know the efficiency of the mid driver/horn combination to fix the settings. It sounds better.

Delicious2 Posted April 26, 2012 Author Share Posted April 26, 2012 thanks for the opinions Craig and Dean. What am I to make of the difference? ES/complex vs first order/Simple? Quote Link to comment Share on other sites More sharing options...
Deang Posted April 26, 2012 Share Posted April 26, 2012 Correct. The ES has a lot of parts and would be considered rather complex. A first order filter would use two caps, a coil, and the autoformer (four parts total). Actually, the network you have is pretty nice -- it just needs to have the capacitors replaced.

Autobocs Posted April 27, 2012 Share Posted April 27, 2012 I like the Universals in my KHorns and the Cornscala-walls in my Cornscala's I have no love for the type A crossover. Tried them. I didn't like the Super Slopes Dave had in his KHorns either. I am not sure, but I dont think the type a crossovers crossovers will work with Eliptracs unless you have the adapter and the K-55 Paul B Quote Link to comment Share on other sites More sharing options...
Delicious2 Posted April 27, 2012 Author Share Posted April 27, 2012 Thanks for the opinion Paul. I do indeed have the adapters and the K-55s. They sound very good now but as Dean said the caps are probably out of spec. So, are the universals a reasonable compromise in complexity? How important is constant impedance in these designs?

Delicious2 Posted April 27, 2012 Author Share Posted April 27, 2012 BTW, I'm using 25 watt/ch PP triode monoblocks now and will probably try some low power SET designs in the future. Quote Link to comment Share on other sites More sharing options...
Marvel Posted April 27, 2012 Share Posted April 27, 2012 The constant impedance usually means more when you are using tube amps, especially so if you move to low powered SETs. The lower order crossovers also work well with the low powered amps, as you don't want your amp power getting sucked up in the crossovers. That's one of the reasons I built my modified DHA2 crossovers to use in my LS. Bruce Quote Link to comment Share on other sites More sharing options...
Deang Posted April 27, 2012 Share Posted April 27, 2012 It's a double edged sword. Those networks smooth the impedance, but the swamping resistors suck up some power from the amp. Quote Link to comment Share on other sites More sharing options...
Delicious2 Posted April 27, 2012 Author Share Posted April 27, 2012 thanks for the reply Bruce. I'll search to learn more about your DHA2s. Quote Link to comment Share on other sites More sharing options...
Delicious2 Posted April 27, 2012 Author Share Posted April 27, 2012 is the ALK universal a good compromise - not too complex/eating up power but also gentle slopes/lower order (same thing?) and constant impedance? Quote Link to comment Share on other sites More sharing options...
