Albatross

Hi Pat, I went back and looked at the picture of your speaker...is the port where the k400 used to be closed up and replaced by the K510 on top of the cabinet? It looks like the hole in the K510 is 2", is it a midrange that goes in there? I also don't see any driver in your K510, is there one in there? Thanks for the info.

Drats!!!! Those La Scalas got sold out from under me.

Thanks for all the great posts...how many of you are gamelan fans? I have to say it is an interesting instrument, however, I do perfer the sitar or even the santoor . Anyway, I am seeing a pair of La scalas from the early 80's for $600.00 in my neighborhood...they are a little "used looking" but they are said to be operational. I always thought I'd get Cornwalls because of the bass and then add the La Scala horns. Can any La Scalanator out there give me a reason and a push towards these. Any additional benefits of La Scalas over Cornwalls other than sensitivity and midrange sweetness (obviously that can be enough)? What does a LaScala person do about bass? I've never heard them and don't have room to put them in the corners to add bass response. Is there a mod on the LS for bass? To make the Jubscala What do the two horns choices run $? The driver for these horns is a Klipsch, but is it an Eminence or Atlas product bought by Klipsch or is it proprietary? I don't see going wild with digital devices for time alignment, unless it makes one see God. What are the more natural ways of time aligning with the Jubscala? Thanks All !!!

I think David's idea of having a base to judge mods on is a great idea even though I don't know if I can hold back my experimenting.

I'm about 4 hrs from Seattle...Jubscala's sound fun...anybody have a picture of them?

Thanks for all the replies. Good insights and good fun. I've spent a lot of dough and a lot of time with Audio over the years trying to find the right sound. I spent twenty years selling it and have had some interesting systems, but mostly I would critique the system when I listened rather than merge with the music. I have heard some Klipsch/tube combos that I thouroughly enjoyed...Forte's with a Dynaco ST70 to name just one. So I am looking into possibly building a Cornscala at this point, but want to do some mods that I've learned from other high-end speakers, such as reducing the size of the box horizontally to the woofer (but keep the same internal volume), possibly try to time-align the driver complement and have the horns be in open air (or minimal surround). I guess the question is...Does this stuff matter with horn speakers. I've got just enough information to get me in trouble, since I like to experiment...after reading about Edgar Salad Bowl Horns, my wife has been hiding our wooden salad bowl. One other question...what should a speaker builder know about a horn's particular frequency? I thought the driver gave the frequency?

I come from the land of high-end without horns. Why horns? What are all the things a horn will do for a speaker?

I'm going to build a pair too...did you get the Cullison plans for the build? if not lets talk. I too am going to use MDF, but probably am going to use Bob Crites Woofer. How far have you gotten?

SUWEEET!!!

I want to start a DIY building project based on the Cornscala projects I've seen on here. It look like the Cornscala II uses the actual box or box size of the Cornwalls , for the woofer (be it the Klipsch K33E or Bob Crites' CW1526C cast aluminum woofer ) and adds into the box the Atlas PD5VH midrange driver with a horn that fits into the Cornwall box itself (Al's Trachorn 400 or others with the right depth)above these the K79K tweeter or Bob Crites aftermarket tweeter.. The original Cornscala uses the K401 which has too much depth for the Cornwall box, so a special size cabinet is built just for the woofer above this an opened-back box is built to house the crossover, the PD5VH with the K401 horn and the same tweeter as above. Are the crossover for both the B-Type Cornwall crossover? Or are they one of the B1, B2 etc.? Has anybody heard both of them to comment on which sounds better? Has anybody tried eliminating the opened-backed box for the midrange and tweeter in the Original Cornscala and just used a stable facade (no side cabinet, minimum wood on the side of the horn)? or played with time alignment with good results? I've got lot o' questions but this will suffice for now...any help will be greeted with great appreciation.
