  1. I don't know about the Caps. 

    Nick described an improved power supply... better resistors and caps. I signed on as he would know better than anyone. (Bought directly from Rogue).

    The amp can handle KT88/6550s. Im pretty sure it cant do el34s.

    Its a manual bias. It has 4 individual bias pots to dial it in.

    Cornscala horn speaker - ampsandsound Hudson
    For sale is a new Cornscala 3 way horn speaker system. Selling off my newly built Klipsch style Cornscala's which are modeled after the famous Cornwalls and and built by staff at ampsandsoud. Exactly the same driver compliment as the ampsandsound Hudson. 

     

    All parts are new. For those who don't know a Cornscala utilizes the best parts of a Klipsch Cornwall and a La Scala together.

    Cabinetry is done with Baltic birch and utilizes biscuits and additional bracing for strength, reduce distortion and resonance. 3/4" Ply with ¼" MDF for a perfectly flat, no resonant surface. Each panel is 1" thick. All braces and back panel are secured with ¼-20 fasteners.
    Black satin lacquer. Gorgeous on the eyes.

     

    Low frequency driver includes massive direct radiating 15" woofer for bass. This is the same woofer use in the Klipsch 904 and in the Cinema line. The woofer's weight rests on its shoulder and not its face to increase rigidity and minimize basket flex. The additional double motor board around the woofer provides isolation and the rigidity needed for truly chest thumping bass.


     

    Midrange horn is sourced from fastlane audio Eliptrac 400 with Fc@ 350 and being crossed @ 450hz. 
    Midrange driver is the famous B&C DCM50, Paper Diaphragm material and incredible 400hz usable range. 

     

    The Tweeter is fastlaneaudio Contrac (Conical Tratrix Horn) paired with B&C DE-10 Mylar diaphragm crossed and 5800hz will outside of the range of the human voice. 

    Crossovers are ALK CSW-450 which is a custom licensed crossover, combining the AP12-450 and the cornscalawal high frequency section. This is a significant improvement over a stock cornscalawal as it proved a 12db 2nd order crossover on the bass thus providing tighter and faster bass response. 

     

    All internal wiring is silver plated teflon. This is master piece of a project and far more than the sum of its parts.

    Cabinet: 34"H x 24" W x 16" D
Weight: 145lbs/per cabinet
    Frequency Response: 34Hz - 20Khz -3db, 98db

    Willing to ship via road freight. Extensive experience transporting via road freight, reasonable pricing.

  3. The speakers in the ad are not the same as the Hudson. Different cabinetry, driver compliment/crossover and finishing. They are amazing sound in their own right but not the same. 

    Re speakers, ampsandsound generally only builds on spec at this point. Most customers like being able to chose exactly what they want. 

    I however, love building speakers... as I have done for many years, I still build about 2-3 pairs a year.... listen and sell off at a reasonable price. Ive taken to changing the ports to differentiate these more clearly now... triangle ports. 

    As an side, Ill be listing a pair of my personal speakers later... Finally need to complete a pair of my Royals... JWC Bass bins with Daves horns. Its been sitting in my garage staring at more for far too long. Time to own a pair of the big boys. 

  4. Bought a pair that were never used. Installed and tested, have less than 1 hour of use.

    Ive compared the BMS 4592-Mid to the Radian 950Be, B&C DCM50 and yet these were hands and feet above. 

    Price is firm. Nearly impossible to from US speaker had to wait 6mo before they came in.

  5. Hear are a few Ive tied and thoughts

     

    The very best ever head... BMS 4592 Mid

    2nd. B&C DCM50

    3rd. Radian 850 with Be driver.... sooooooooooooooooooooo hard to work with.... tuning it might kill you but if you get it right its an amazing choice for 2way.

    B&C DE750.... its a monster... no brainer choice... will make you think you have better bass. Heavy... horn will need to be braced.

    Fatial HF140/200.  Sings... goes low... goes high... light no complaints... everything is right. Nothing disappoints but nothing blows you over.., no weight issues.

    B&C DE85 Smaller version of 750... less impressive... Like the HF200

    Had a Pyle what was a parts express closeout... its was a close of a PV or JBL.... huge... like stupid big.... inefficient as compared to the rest. But sounded great... practically gave it away and went to 400hz.

  6. Ive tried the original spec and the revision... biggest difference was total power out. 

    The original power supply was terrible. If you look on the DIY audio forums... this mod had been around for a long time... perhaps as a workaround for the poor performance of the 19V?

    The amp section is incredible, but the laptop supply leaves much to be desired. Building a linear supply is pretty simple but if willing to do so, perhaps the F5 or F6 would be a better choice.

    I left such endeavors to ebay as I have. Regulated linear supply was my ticket. 

    The orig ACA were monos... love that. The current ACA is a dual mono single box unit. which can be doubled for monos. 

     

    In short... if wanting a project... the ACA is definitely a hot ticket. 

    If wanting reference sound... need to upgrade the power supply.

    For must of us, a 5-8watt amp is all we would need... the rest is sonic presences.

  7. I contine to have a soft spot for the LS. The Khorn can sound amazing, but placement is a real consideration. I have Jub clones. Likely the best speaker Ive very head... ALK crossovers and all, but the sheer size killed them off. Folded horns have a legitimate place in the order of things, but when balancing size and performance the size question becomes the weak link. 

    The Sunn speaker looks like some bad PA close stuff I see all the time with DJs.

    Uh....not exactly at least as far as Jube is concerned. These low freq cabinets are like @jwc 's mini punch(I think that's what he called it) that GotHover WAS going to make kits for.

     

    I have 3 pair of the mino punches. They were easily better than k horns but not match to the jubs. With the CSW45O that is jub/mini punch compatible they tied the Jubs.  Dig deeper. JWCs design is horn loaded with a tratrix flair and ported.  Total pain in the *** to built but a real contenter to the jub/k402 combo.  And more importantly... so much smaller. 104db if I recall.
