Dneu2011 Posted February 22, 2020 Share Posted February 22, 2020 I have a friend that had some spare parts pulled from a single La Scala and I was wondering if I could build a Cornscala with it to use as a Center channel with my Cornwall III’s. I have a KT77 Tweeter, A-55-G squawker, and a Dean Wescott La Scala crossover. I also have some spare Hawthorne Augie 15’s but not sure if I can incorporate them somehow in the build... Thanks.

JohnA Posted February 22, 2020 Share Posted February 22, 2020 Sounds like a good start on another Cornwall for your center. You would want the crossovers to match so the voicing matches. Quote Link to comment Share on other sites More sharing options...
boom3 Posted February 22, 2020 Share Posted February 22, 2020 Yes you can build a center from Klipsch parts, I did. Two K-1077 8 inch woofers, the K-401 horn, PV5 driver and Crites CT125 tweeter. Bob Crites told me that best results would be to use a K-401 horn instead of the K-601 horns in my flanking Cornwalls. He was right since the center channel is predominantly vocals. A grille that matches the Corns covers this in normal use. The CRT based TV is long gone replaced by a flat panel. Quote Link to comment Share on other sites More sharing options...
Dneu2011 Posted February 22, 2020 Author Share Posted February 22, 2020 Thanks for the feedback. Should I just message bob for his input? Quote Link to comment Share on other sites More sharing options...
Griffen Posted February 24, 2020 Share Posted February 24, 2020 Parts make good center channels. This one is a great match for my LaScalas. I used a Heresy tweeter and midrange and selected Focal dual 7” woofers and ported. The crossover had to be re-configured from the type E that came came in the Heresy. The frequency response is about like the Heresy, but with a little stronger bass and the timber matches perfectly across the soundstage. The cabinet face is the same as the LaScala top and the depth adjusted to the woofer parameters to perform well. I had to take a few dB off the tweeter and midrange to level out the volume with the woofer. Some might ask “why didn’t you just use the Heresy?”; I wanted it to look like a center channel and fit in my console. Good luck on your project! 1 Quote Link to comment Share on other sites More sharing options...
Chris A Posted February 24, 2020 Share Posted February 24, 2020 If you intend to have off-axis seating,i.e., more than 15 degrees off-axis in your listening room, see: The easy fix is to orient a center MTM-type of loudspeaker vertically, not horizontally. This is the same type of configuration as a Dunlavy or Duntech type of setup: Chris Quote Link to comment Share on other sites More sharing options...
JohnA Posted February 24, 2020 Share Posted February 24, 2020 Interesting post, Chris. I have a modified H1 as my center, turned sideways because the old room had a low ceiling. I knew it would have off axis irregularities (wasn't sure which/how many) but I like the effect. Some guests think the TV speakers are on. They dont know how crappy the TV speakers really are. 🙂 Quote Link to comment Share on other sites More sharing options...
boom3 Posted February 25, 2020 Share Posted February 25, 2020 My center's mid/tweet baffle is titled 10 degrees to aim at the ears of seated listeners, not their ankles as would be the case if the baffle was perpendicular to the floor Quote Link to comment Share on other sites More sharing options...
