BEC Posted April 24, 2006 Author Share Posted April 24, 2006 Elton John is currently rocking the old shop with Philadelphia Freedom on one Vert. Cornwall and one Cornscala II. No Klipsch speakers were harmed in production of this speaker. Bob Crites Quote Link to comment Share on other sites More sharing options...

BEC Posted April 24, 2006 Author Share Posted April 24, 2006 Please describe the sound differences? The Cornscala II sounds like the Cornscala I. Sadly, the Cornwall sounds like a Cornwall. It needs a better midrange horn and a better tweeter. Bob Quote Link to comment Share on other sites More sharing options...
meagain Posted April 24, 2006 Share Posted April 24, 2006 Wise guy! So you feel this mid-horn setup is comparable to the 400? Is there anything that it doesn't do as well or anything it does better? If so - how would you describe these differences. And - would a split version of this not work at all due to 'cabin' volume issues? Be kind, a split version (if it's truely all it's cracked up to be) would be my dream center. Quote Link to comment Share on other sites More sharing options...
mungkiman Posted April 24, 2006 Share Posted April 24, 2006 Bob, did you make the internal volume different to compensate for a larger mid-horn? Just curious. If this was covered and I missed it, I apologize. Chris Quote Link to comment Share on other sites More sharing options...
BEC Posted April 24, 2006 Author Share Posted April 24, 2006 Meagain, I am not good at the use of audio terms. I have some specific recordings to check out a midrange and the new horn passes with flying colors. The best demo that could be given I think is to listen to this set-up I have right now with a Cornwall and the Cornscala II playing together. I have always thought that the midrange horn in the Cornwall is just too small. I think that most who have tried a larger horn have agreed that the larger horn, K-400, 511B or others sound better with the rest of the Cornwall drivers. This Pyle Pro horn just happens to be one that will actually fit inside a Cornwall size cabinet. Splitting it would be fine, but the woofer has to be in an enclosure of approximately the volume of this cabinet. The midrange and tweeter can be in a cabinet or just on a baffle board. That would be like the first Cornscala I built. Bob Crites Quote Link to comment Share on other sites More sharing options...
BEC Posted April 24, 2006 Author Share Posted April 24, 2006 Chris, Yes, I did the whole submerge in water trick to calculate all the volumes. Turned out that to have the same internal free volume that the original Cornwall I used for a model has, the depth of the cabinet had to increase by 1/4 inch.

mark1101 Posted April 24, 2006 Share Posted April 24, 2006 Bob, The new speaker looks great. I have a question. Did you add any dampening material to the inside of the cabinet? Pictures? Quote Link to comment Share on other sites More sharing options...
Clarence Posted April 24, 2006 Share Posted April 24, 2006 Bob you have PM. Quote Link to comment Share on other sites More sharing options...
BEC Posted April 24, 2006 Author Share Posted April 24, 2006 Mark, I haven't added any damping material yet. I am not certain how much difference that makes. On the original Cornscalas I built, I completely lined the inside of one bass bin on one of them and left the other bare. I have never been able to tell by listening which one has the damping in it.

psg Posted April 24, 2006 Share Posted April 24, 2006 What is that mid-horn lens? Since it's no longer a K-400, then it's no longer a Cornscala, right? But the lens is much bigger than a Cornwall as well I suppose... That would make a sweet center! Please make a "vertical" model for horizontal mounting, and easy shipping terms to Canada!

BEC Posted April 24, 2006 Author Share Posted April 24, 2006 Rats!! Got a nasty resonance below 100 hz at high volume. Have to work on that. See, I tell the bad with the good. Bob Quote Link to comment Share on other sites More sharing options...
jwc Posted April 24, 2006 Share Posted April 24, 2006 Bob. I have always wondered why your port doesn't have the side supports like the Cornwall. I noticed in the other recent Cornscala thread that they didn't include it either. I was assuming that the port side supports were needed to prevent port resonance. I really don't know the answer. Here is the port side support on a Cornwall: Quote Link to comment Share on other sites More sharing options...
jwc Posted April 24, 2006 Share Posted April 24, 2006 Here is how I reproduce the side supports on my Cornscala and here is a bar to prevent resonance of the sidewalls. This is a 1 1/2 by 1 1/2 hardwood. jc Quote Link to comment Share on other sites More sharing options...
consistent Posted April 24, 2006 Share Posted April 24, 2006 Hey Bob, Is the mid horn a PH2380P? Does the Atlas (K55) screw right in as from memory the thread should be the same? Looks looks a tractrix Quote Link to comment Share on other sites More sharing options...
