Bonzo Posted July 4, 2015 Share Posted July 4, 2015 http://www.audiokarma.org/forums/showthread.php?t=284353 In the interest of marital harmony, I am reluctantly selling my big DIY two ways. Components are a JBL 2445j compression driver with matching Constant Directivity Horn. Woofer is the Crites cast frame 15" that I believe is built by Eminence. The crossovers were custom made by the builder of the speakers. He based them on the ALK-500 Low Pass design, 12db @ 500hz and a custom design 12db High Pass @ 500hz with CD. It has horn flare compensation to allow them to be used as a two way. The network is unique in the way it varies the balance between the mid and high frequencies using a 16 ohm L-pad as a shunt element. This burns off mid-range energy where the highs are bypassed by the 1uF element. I'm sure that's clear as mud. I can provide a list of components to interested parties. They are built out of 1" MDF with oak finish motor-board. Outer finish is Duratex. I have extra for touch ups. They have massive internal bracing and sound dampening material inside. I linked an AK thread where the builder, "Santa", posted progress on the build. Starting at page 7, posts 105, 109, 111 and 112. They are solid as a proverbial rock and very heavy! Fortunately, there are casters to help move them around. There are no grills, they don't need no stinkin' grills! They started life as a three way with a Selenium compression driver and wave guide as a tweeter crossed at 10Khz. Most of the time I couldn't tell if the tweeter was working or not. They sound much better now as two ways. The JBL compression driver is rated up to 20Khz. Probably a stretch but I'm lucky if I can hear 12K on a good day. The down side, there is a hole where the wave guide was. My thought was to put two small integrated tube amps in the separate tweeter chamber where the controls could be accessed through the front. They are awesome sounding speakers, especially with tubes and it pains me to part with them! I have roughly $1500 into them so I will start there. I will always consider partial trades for interesting audio gear. I could use another quality integrated amp. These are for local pick up in Redding California, about 2.5 hours south of the Oregon border and 2.5 hours north of Sacramento on I-5. Bring a truck or van, I will assist loading them. I can meet or deliver within a reasonable distance for the right deal. I will post more pictures shortly. Here's one next to a Cornwall III. Thanks!

Bonzo Posted July 4, 2015 Author Share Posted July 4, 2015 I forgot to mention, the builder used Speakon connectors for inputs. I currently just run speaker wire directly to the inputs on the crossovers. The input wire to the connectors is still present and can easily be connected to the crossovers. I can provide two long lengths of speaker wire with those connectors. They provide a very solid connection and are used in most PA and Pro speakers. I do have coverings for the rear panel opening though they never been installed and need to be pre-drilled. Here's some additional pictures. The price is negotiable and, again, I always will consider interesting trades. If you have any questions, please don't hesitate to ask.

mwells Posted July 5, 2015 Share Posted July 5, 2015 I came across the linked thread at AK last weekend while doing some Cornscala research. Those sure are some heavy duty cabs and I bet they sound great. I am sorry that you have to part with them. GLWTS Mark Quote Link to comment Share on other sites More sharing options...
Bonzo Posted July 5, 2015 Author Share Posted July 5, 2015 I guess I could buy a pair of Pyle Waveguides to fill the holes? That's what was in them when they were three ways. They are only about $30 a pair from Parts Express. It would make them more aesthetically pleasing. If the buyer wanted to turn them back into three ways, you would be 1/3 if the way there, parts wise. All you would need is a compatible compression driver and an additional crossover. I could put you in touch with the builder. I'm sure he would be more than happy to do that. Quote Link to comment Share on other sites More sharing options...
Bonzo Posted July 5, 2015 Author Share Posted July 5, 2015 I have re-evaluated my asking price. It looks to me that the replacement cost of the components is approx. $1K+. I then asked myself if I would pay $1500 for them as is. The answer was no. Seeing as they will be just sitting soon, I am going to lower my asking price to $1200. I will still consider interesting trades, like a restored tube integrated, or ??? I will also assist with pick up and/or delivery for the right deal.

Bonzo Posted July 9, 2015 Author Share Posted July 9, 2015 Just bringing these great speakers back to the top. Currently listening to "Rit's House" by Lee Ritenour, awesome! Quote Link to comment Share on other sites More sharing options...
Bonzo Posted July 18, 2015 Author Share Posted July 18, 2015 I have ordered a pair of Pyle waveguides to fill the holes. They will look more presentable but, it's the sound that will grab you! I wish I could keep them. I am open to partial trades for quality bookshelf speakers, a pair of RB-5's or RB-75's would be nice. I'm also looking for a quality CD player, preferably with SACD capability. Just need to move them before my better half puts them out on the sidewalk with a "FREE" sign on them. I will entertain any offers, thanks. Quote Link to comment Share on other sites More sharing options...
Bonzo Posted July 21, 2015 Author Share Posted July 21, 2015 (edited) 07/20/15, I got the waveguides today and mounted them in the holes. They look much better now IMHO. If I could find L-pads with a longer shaft, I may be able to mount them in the horn opening? Edited July 21, 2015 by Bonzo Quote Link to comment Share on other sites More sharing options...
Bonzo Posted July 28, 2015 Author Share Posted July 28, 2015 I would take $1K for them if you come and get them in Redding, CA. Thanks Quote Link to comment Share on other sites More sharing options...
