I was planning to do a Cornscala build but have shifted gears. The following parts are up for grabs. The woofers and midrange are open box and never hooked up. The tweeters were run in my K-Horns for about 2 years but work perfect. The Eliptrac 400 was a flatpack kit from Dave that I glued/pinned/clamped but never got further. Crites Cast Woofers - $300/pair SOLD! Eliptrac HF w/B&C DE10-8's - $200/pair SOLD! Eliptrac 400 horns - $300/pair SOLD! B&C DCM50-8 drivers - $900/pair SOLD! Located in Holland, MI.

The bracing would help remove some of the midbass "boominess" coming from box resonances. The Cornwall IV added the bracing based on feedback from users over the years specifically to address this. Ideally, if you added the braces you would need to expand the interior volume by the volume the braces displace. This is a minimal volume so probably not an issue and would most likely fall within driver tolerances anyway. As far as the horn, I have not heard the stock CS-B horn so I cannot comment. I plan to do a custom build so I went straight for the Eliptrac 400.

I don't know of any new production 45's that are really that good. Get yourself some National Union etched base or spend that money on some CX-345 or UX-245. Nothing can touch the sound of the old globes.

45 is probably the most neutral linear tube there is. I prefer them over 2A3 and 300B personally. They used to be affordable but now prices are getting up there. I am running globe RCA UX-245’s which sound much better than ST bottles.

I already have the Eliptrac HF horn and B&C DE10's on my Khorns that I will use. Dave recommends the DCM50's on the 400 so will probably go that route since I am not a fan of titanium drivers. I am adding front to back bracing and a split-back with a brace so I should be able to push the front forward to offset the volume loss of the bracing to fit the larger drivers.

I just ordered the Eliptrac 400 flat packs so planning to build the CS-B style with the Eliptrac HF, Eliptrac 400, Crites cast woofer and ALK CSW.

Any updates on the ALK CSW? I am considering a Cornscala CS-B build as I already have Crites cast woofers, ALK CSW and Eliptrac HF/DE10. I was also considering the Eliptrac-400. I am running a 45 SET so I need the efficiency!

Thanks Shakey! It might have been Forte 3 ... whichever has the new larger horn. I did see teardown photos of the CW4 and they have 2 braces front to back at about 10 & 2 around the woofer. I was thinking of doing the same if I build Cornscalas. Are you CW4's still stock? Curious if you have dug into the crossovers yet? My friend with the Forte's did and he said the resolution is even better than stock! There is something magic about that new midrange horn! 😁

OK ... first the background. I had RF-7's running off an ST-70. When I moved, the new room is small ... 12'x14' and I am listening across the shorter dimension so the RF-7's were no longer an option! I picked up a set of Cornwalls with Crites crossovers and Crites titanium diaphragms and LOVED them! Ended up upgrading to a Tubelab SE amp running Cunnigham CX-345's. I came across a good deal on Khorns and wanted to try them so I bought them and upgraded them with Crites cast woofers, ALK crossovers, Elliptrac tweeter with B&C DE10 and damped the K400 with bedliner on the back side. They sound incredible but don't have the bass the CW's did and the K400 still has it's quirks and imaging is so-so. A buddy recently purchased the Forte 4's. I went over and immediately fell in love with the new midrange! So, here I am looking to either revert back to a set of Cornwall 4's but then I though why not Crites Cornscalas? I already have the cast woofers, ALK crossover and Elliptrac w/DE10. I could pick up the Crites CS-B midrange and build the cabinets (braced of course!). The only thing I am really missing is the CW4's mumped horn at that point but I imagine the M2380's with a 2"CD will get me pretty darn close at about 1/2 the cost! For those of you that have the Cornscalas, are they good for a smaller room with low power (2W)? I know the Cornwalls performed excellent in this scenario. Would you use the Crites CT120 or Elliptrac w/DE10? Or ... should I save up for the Cornwall 4's? I'd probably still end up replacing the crossover in the CW4 anyway ... who uses ferrite core inductors for mids and highs??? 😡

Then these are screaming BUY ME to you! 😁

Thanks! I'm kind of shocked myself ... the price is a STEAL! DTO - you should sell something and make room! 😝

BUMP

Thanks! It is composite rosewood veneer. I painted the surrounds and rear satin black to make it pop.

I got them when ALK was still selling them. He no longer offers them.
