MEH Synergy Posted November 14, 2019 Share Posted November 14, 2019 Nice build list. At some point, I will do the same (some time down the road). Will keep an eye on this thread. Thanks for sharing. Quote Link to comment Share on other sites More sharing options...
captjoe Posted November 14, 2019 Author Share Posted November 14, 2019 No problem will try to keep it current. Love to do the cabinets but have limited space in my shop. Quote Link to comment Share on other sites More sharing options...

I built mine last year. I would give your woofer selection a second thought. Claude just advised me to use the kappalite 3015lf4. Says it's a much better woofer than the 15c. 1 Quote Link to comment Share on other sites More sharing options...
justinsweber Posted November 15, 2019 Share Posted November 15, 2019 If I can make 2 suggestions. ALK ES and AP12 networks expect to see a predicted inductance of the voice coil. Meaning that it’s set for a K33/K43 woofer. The Kappa 15C has been measured by Al and is also compatible. If you use something different the crossover could not be expected to perform as predicted. Maybe it wouldn’t matter. Al and only a handful of other people can do the level of calculations needed. In short, use a k33 or kappa 15C or ask Al. Secondly, the DE85 is lovely, is perfect especially for this application. That said. The DE750 was a monster. Bass was much improved. It’s the same diaphragm but 2x the magnet. 1 Quote Link to comment Share on other sites More sharing options...

justinsweber Posted November 15, 2019 Share Posted November 15, 2019 The universals are 6db filters and don’t have same issue. I’d want a specific woofer then the cornscalawal but I’d want higher older filters... need to be kliapxh compatible with k33 or 15C Quote Link to comment Share on other sites More sharing options...

justinsweber Posted November 15, 2019 Share Posted November 15, 2019 Are you discussing a cornscala or super heresy. The 15c is a suggestion for a cornscala. I believe the original post is about building a cornscala. He was showing his previous efforts with the super Heresy. Quote Link to comment Share on other sites More sharing options...

justinsweber Posted November 15, 2019 Share Posted November 15, 2019 The kappalite 3015lf4 is a 12” woofer. If doing a cornscala you need 15”. So, Buy a 15” from bob crites. He has 2 very good choices or get a eminence Kappa 15C from parts express. 1 Quote Link to comment Share on other sites More sharing options...

Claude just used it in a super cornwall, says its 4 times the woofer of a 15c. Quote Link to comment Share on other sites More sharing options...

I agree about the Crites woofer being a good choice for a LaScala, Khorn, and Cornwall....................but a Kappa 15C's Xmax of 2.5 mm could be an issue in a Cornwall. I only recommend it for short horns Like LS or Belle, even my Quarter Pies, but not Cornwalls. They work and sound good, especially in the upper end of their band (400-500 Hz.) but not for bass freaks in a bass reflex box, where you may need more Xmax.

Mostly for the high Xmax and the fact that an old K55/K600 horn in a Cornwall responds down to 500 Hz. even though Klipsch claims only 600 Hz for it. Or 700 Hz. in the case of the Cornwall III, since it uses a horn similar to a Heresy. Quote Link to comment Share on other sites More sharing options...

To be a TRUE CornScala, it should, technically, have a K400 horn with K55, just like a LaScala. I built one back in 1975 before there was a name for it.

It had good Xmax and will work well in a Cornwall. It has a slight bass peak at 40 Hz. which some people might prefer over the Kappalite.
