When Ive built splits, Ive made sure that my Cab vol matches pretty closly to that of the ~6.5cu ft. that the CW used. Where single cab or split the vol needs to be close to the same for the port and shelf config we all use.

Not in the last pic, is my 100% Bob Crites sourced Cornscala. I have to say, each is different but I would take any of my 3 pairs happily, the last pair more happily than the others :-). The PH800 is an improvement over the K401 for sure. Dave’s horn beats them all. The Cornscala lets builders go from mild to wild. We have choice of crossovers, drivers and horns at any price point... Sort become the Dynaco ST70 of speakers.

The 2way/3way swtich was for both use with different types of music and verification. If you have the ES Network + AP then the switch is an easy add in. The extra parts for the 3way I would say were not needed unless you want to get the last 5%. I wanted to try everything I could in one package and then stop build for a while... This was the result. Going 3 way was addative to the top end shimmer (forwardness). Without it seemed more relaxed. Dave's tweeter lens/horn was a serious addition. All the parts came together well and produced a cohesive whole.

James I think the Bass is right is each speak, just a bit different. I actually built a tappered transition piece for my origonal split conscalas... fixed any port mismatch issues... took nearly 8hrs worth of wood working... :-(.

Really sweet, Not my work.. Dave Harris and ALK, and the origonal builder of the Cabs... I do love Klipsch Speakers... Now I just need a bigger listening room.

The Naked shot

Part of the Magic

The Steriod parts... The Tweeter lens made such a difference. We were going to us the Selenuim CD Lens, but Dave's was a monumental improvement.

lets start this build

If any of you have read some of my previous posts, you can see that I enjoy build Klipsch inspired speakers. 1 mistake I always seem to make is wanting to build the cabs just a bit bigger and then coming to my senses and adding material to get the cab back to the correct volume. So far I have built, a pair of single cab Cornscalas (All sourced from Bob Crites (K55, PH-800 horn, Ct125 tweeter, Bobs 15" Woofers, and his Crossover)). 1 Pair of rehabbed Heresy's (New Crites crossover, and 12" woofers, APT50 tweeters, 1 pair of Split La Scalas (New everything from Crites... again :-). 1 pair of CS-1s Parts from Bob, and what I thought were my last speakers, my Split Cornscalas (K401/K55 Selenuim 220ti/HM17-25, Eminence 15C woofers and Bobs crossovers. During the last several years, this has been my hobby and how I’ve spent my free time... listening to music in the middle of night, etc. Part of the hobby has been the continuous learning process. All these builds resulted in a bunch of speakers sold for 50cent on the dollar as finding the right buyer can be hard. As a result I didn’t get to keep all my creations but held on to the cornscalas as they were the most pleasing to me. About a year ago I began to lust after Bob's part list for the Selenuim based 3way… using the massive D405 driver. Shortly after the discovery of the HF200 I saw Dave Harris’ Eliptrac horns and fell in love, but couldn’t justify the costs. 2 save cash I tried the HF200 with the JBL2380 as a 2way and they just didn’t have the same luster my split cornscala’s had. (I built the 2way into a separate top hat and was able to A vs B the 2 speakers. Some parts left to fund my expansion, and I got the Eliptrac 400 and Dave was kind enough to graft into my existing 2way cab. As a 2way (HF200/ Eliptrac 400 1st order crossover @500hz.) I still was not in love the Eliptrac 400 was a significant improvement and yes I knew I could live with it, but this was to be my last speaker for a while. So I was left with the 3way top-hats in the closet, easting up serious space… I was unwilling to sell and lose more money, and I had the Eliptrac 400 that were a serious improvement, but I missed the 3way sound. What to do? I did some more reading from Dave and ALK and started thinking about space and my existing investment., and what I could afford for floor space. I knew I didn’t have the time to build another set of cornscala’s from scratch. Having seen Dave’s work, I asked if he would build me a set of narrow Scala 3ways with his horn. Dave said he couldn’t due to time constraints, but that he has a Split Cornscala cabinet empty and needing a good home. (Now Id have a Harris build speaker!). This Split Cornscala was the initial work of another forum member and the craftsmanship shows. In speaking with ALK I became interested in the ES5800 network and the possibility of 2way/3way on the fly operation. So we are using ALK’s AP12-500 for a gentle slope and the ES5800 for the 3way operation. I hope ALK or Dave can chime in on the work… I got to be the recipient!. There is a switch on the back that allows for toggling between 2way and 3 way operation. Dave’s cornscala is a show piece of what’s possible, his Eliptrac 400/Faital HF200, his Conical tweeter lens for the Selenuim 200ti and the Eminence 15C. All these parts kick *** on their own, but together became my last speaker. When run against my 3 way split cornscala’s (K401/k55, Selenuim 220ti/HM17-25 I found my beloved speakers sounding honky/ and rough in the top end. Im not seriously wondering how to make adjustments. (Im not great at describing speakers… Long story, short… these seemed right. The mid bass, mids and highs were so accurate. I like the bass from my splits better, but that’s a question on cabinet build choices… My bins should never have been made… 3x thicker than they should be… mad as a mistake… though a good sounding one. Needless to say, my last speaker is my favorite speaker.

There Home!

and last be never the least the bins

I got the chance to hang with Dave Harris a bit today. He is work on a 3 way Cornscala, his Eliptrac 400/ Faital HF200, his custom tweeter lens, Eminence 15C and crossovers by ALK. (2way/3way switchable on the fly). When I first dropped parts off at Dave’s he was showing other projects to me and showed me his 1” tweeter lens… I thought it looked bad *** and asked if it could be used on my speaker. Today Dave gave the Selenium HM17-25 a listen versus his tweeter lens. This was the Selenium HM17-25 + Selenium 220ti screw on vs his lens + Selenium 220ti bolt on. When I spoke to his on the phone he said they measured the same, but they sounded night and day different. I had been driving 3 hours and really thought I wouldn’t hear the diff, but still wanted the circular horn anyway as it was so cool! He did a A vs B comparison… the Selenium HM17-25 was played alone vs his setup… my god the difference was not night and day… but far beyond…Never seen home 1 singular part could make such a difference. The lens is the shit… Very happy it will be included in the Cornscala. Ive used the Selenium HM17-25 in my current 3way cornscala and love them, but this comparison was mind blowing… now how to integrate a 2nd set… I promised the wife after this no audio purchases till after the year. :-(

The Jolida looks great...

I got the rack from salamder, thus the caps. Im replacing thr MDF shelves with the butcher block. you can get the same all threat from home dept...

I was given the sugestion to use maple and plain down. Olive oil is the stain/seal.

Im in the process of building/planing me some new sleves.

With the M2380 horn and the HF200 the highs did not need the HF boost... Almost cutting with it in place for me. Dave's horn and the a 3way were just taking the idea as far as I could. My wife is amazingly understanding. My listening room has terrible acustics... Im bebating keeping the M2380 and crossover for a 3rd set of corn scala's.... who knows...Its almost too much, all the different ways to skin a cat. My k401/K55 base 3way was more than enough. 1/2 the people that hear it perfer it over the PH800/k55 combo in the other room... Both are amazingly impressive... yet each seems to resonate with someone. The M2380/hf200 was a close tie to my K401/K55... The Eliptrac won out... Im hoping the 3 way interation will out pace them all. The problem will then be wanting to bring them all to the same level. For anyone building a cornscala, I strongly sugest you design some way of replacing the front baffle... allowing you to upgrad as you see fit without signifficant changes.

Thought Id add some notes after listening and thinking some.The M2380 with the Faital HF200 sounded really good to me, putting it on par with my 3way, K401/K55 Selenium D220ti setup. Each has there own sounds, but either I could live with happily. The addition of Dave’s horn, brought a sense of realism/less honky... I didn’t know I was until it was gone. I do think its the most neutral horn I have ever heard, some HF sparkle seem different, less forward than my 3way, but that was expected.I would list the 2380 with HF200 as a better from scratch option than the K401/K55 Tweeter combo. I would say Dave's horns are a significant improvement to this design as well. (Dave's horn is better the a CD horn (2380 CD Horn). Dave is being kind enough to help with my lastly upgrade, taking his horn to a 3way rig. This will allow us to hear it as a 2 way vs a 3way. Not sure which Ill like better. I listened to the Eleiptrac 400 setup for 2 days and then tried the 3way and switched it back pretty quickly... I did the same test, with the same results with the M2380 vs the K401.

Didnt see much tweaking there, this was a perfect install, and the results are super consistant. Its really interesting, My 3way as a K401/K55 Selenuim 220ti/baby cheek horn is really really hard to improve upon. Or so I thought. The 3way offers some for electronica, pop and less serious listening types of music. BUT I now hear there is a coloration there... even if a subtle. The 2ways tear the 3 way apart in vocals, significant improvement. I can A and B test (placing 1 tophat on the right and the other on the left if needed!).

Last one. Its interesting. I love my 3 way for my electronic music, the 2 way is so clearly better with vocal its amazing. No coloration... definitly an ajustment.
