  1. Ah. They were going to get listed next week. They are called the figure 8. Its a scaled down version of Dave’s drift design. 8”woof rear ported. Goes to low 30s. 1” conical tratrix horn. Used the Dayton clone of the D220ti but has a polymide diaphragm. Whole speaker was sent to ALK for crossover design. 2nd order on LF, 3rd on Hf. Crossed at 800hz. ~92db efficient. They Image so well. As you can see. I’m awash in older projects again.
  2. 12LFA think of it like a better K24
  3. They are the Omens...I love Zu speakers. The DWs are great, super close to the Omens now... esp if you can do the cap upgrade for $100.
  4. I built these as my Cornscala replacements. These are the best Heresy/12" 2way Ive heard. 12" eminence Pro woofer Faital Large format Eliptrac horn... its the same horn I use on my 2way cornscala and bob uses on his Cornscala D. Faital 1.4" driver. Crossing conservatively at 800hz. Custom ALK AP12-800 with values adjusted to the Eminence woofer... its not an off the shelf ALK AP12. I had Al measure this woofer a few years ago so the crossover is matched to the woofer. Think off this as a small Cornscala. ~ 1/3rd the size. Bass is solid to 50hz and mid range to die for. I have ~$2000 into these. Will consider reasonable offers. Justin 323-868-9722
  5. Selling off my office rig. Not a current model but one of my favorites. 3watts with 6l6gcs as is, 5watts with KT88s. Incredibly quite... like headphone amp quite :-0. 8ohm for headphones and 300ohm for headphones. 8ohm speaker outs with cards binding posts. Hate to see it sit unused on a shelf. 1200obo Justin 323-868-9722
  6. Its the older eminence as I recall. Once other point of note. The crossover is a CSW 450. I used to make these under lic from ALK. Fully adjustable, crossed at 450. 2nd order on bass. Its like an AP12450 and a AP15-4500
  7. These were completely rebuilt. Man that was good. Dave's larger mid horn, elliptical tweeter and new 15C woofers. The cabs were rebuilt, dog house brace and the back was strengthened to allow the rear panel to sit flush. The casters were to make to party friendly. Love rebuilding them... just couldn't stay permanently.
  8. ALK makes an attenuator that's in series. Its a really nice unit... allows for a great deal of adjustability.
  9. The Encore is a headphone amp 1st but we discovered it works so well as a pre. The Juicy gear is true pre is every sense as are the NOS Valve pre. Id love to hear all three in the same rig. Id suspect the NOS Valves would be the winer, but the Encore could have honorable mention on multi use merit.
  10. Thanks JC. Glad you’re enjoying. The 1626 is a really magical sound.
  11. Daves thinking on the subject is bar none... way smarter than me... that said. I would suggest 2 simpler mods you might really like. 1st, bypass C1. Its for DC blocking... you don't need with anything modern. 2nd and more interesting... replacing the 50ohm resister in the PS with a C354 choke will go a long way to reducing the noise floor... likely to improve the bass too. You'd drill 2 holes and mount it up too. I think Dynakitparts even has pictures of this done. The ST35 was called the poor mans Macintosh for good reason. Its sonics are lovely. At 15watts, its likely more than enough power for your Cornwalls. Congrats!
  12. Ive owned a pair of chartwells and they were pretty amazing, needed a huge sub though. I do suggest audiogon or ebay. Your price is for mint condition...
  13. I haven't received yet, Ill get it on the bench and will find the culprit. Im my experience... 150+ amps or so, less than 10 have every had anything actually wrong with the amp... tubes tend to be the culprit. Either way Ill have her back to singing ASAP.
  14. Received some great parts from a friend. Selling the JBL 2327 1" to 2" adapters. Asking $80. 
 Also have the JBL 2425J 1" 16ohm drivers 800hz to 20Khz Works perfectly. Will do $400 for the pair or Train Faital HF140 or HF200 Thanks
  15. I have seen the benefits of the Loki. It’s not just an eq. It has 2db of Gain if I recall. It gives some spin on the ball as they say, that’s a good thing. The ability to pull down or boost up arenas is super helpful.
  16. I own 2 of the Schiit Aegirs super music. More relaxed than I expected. Not the tightest bass but super musical. One of the very best SS amps I’ve heard in a bit. My chain is c2600. 2 Aegirs into my 2way Coenheresy speakers. 94db efficient. Recommend whole heartily
  17. I’m a ALK supporter through and through. That said, you want stock but improved. Crites is the right and answer. The ALk cornscalawal would be the right choice for me but that’s because I dislike the stock voicing and want to be able and adjust my crossover.
  18. Cluad, I dint take offense... Ive learning there's no perfect choice. Building a new allows me to think Ill find it someday. A double woofer would be amazing... might complete with a Cornwall... Much Narrower My cab is 17" wide, 14" deep and 25" tall. If you did a 2nd woodier assuming 14" additional. You'd be at ~39-40" tall... A bit taller than a Cornwall but wholly workable. That said, you'd still end up with a speaker 7" narrower which is significant. What would be the response curve... what's the bass output vs Kappa 15C? Wiring in series vs parallel? Getting ALK to do a version of this would be fun. If all were equal the Eliptrac would be preferred, but it would make it heaver and wider. Using it would allow for 2" drivers instead of 1.4".
  19. For a 2way, finding a horn that goes low well and high is sometimes difficult. At 1200hz on up.... not hard and it was called the econowave. You can use 1" drivers from Dayton and Selenuim. But to go lower than 1200hz ... 1.4" or 2" drivers become needed. I know the JBL 2380 can do it but needs some EQ in the HF. Im not really sure what other horns would do it... Dave's Eliptrac is so special as its a 2" horn that could do 500hz to 18khz without Eq or issues. The next best choice is the Fatial LTH142... its a 1.4" horn. I have loved B&C drivers... the DE85 and the DE750 come to mind for 2way but need a 2" horn. As the Fatial is 1.4" I used the most logical 1.4" I could find :-). This project was expensive... Could have build a cornscala for nearly the same money... Extra plywood was the only real additional cost. This wasn't done as I wanted a smaller speaker to fit my new smaller room. Although the LF12 is 94db which is much lower than a K22. It still makes for a very very efficient speaker which digs lower than any stock Heresy and without the bass hump or porting. That said, lots of paths... many good ones.
  20. Nope. It’s pretty solid. Eliptixla tractrix. 1.4”. 500-to 18k
  21. I like the low slung look but I agreee. The forte as a kit would be fantastic to see. New horns, new divers but same basic design. Was it the forte I that didn’t have the radiator ? I think the forte with the radiator and the chorus are the great equalizers for cabinet size.
  22. As an aside. Risers are from Bob and he makes a fantastic bracket to support the driver. Maybe we will decide to make a mini might and have accessible for all. With the same horn he uses for the big cornscala. Prob need to be priced similar to cornscala kit but for some it’s not the price but the physical size. I orig built these for the wife/tv room. She hates the riser and as such STOLE my smalll cornsclalaa from me. In hind sight the size of the cornheresy is a better fit for my small listening room.
  23. It digs about as deep as a stock CWI. 44-46hz Dave Harris cur the baffle for me. Bob has something similar but does use the big horn. The big horn really adds to the cost but it was about fitting the biggest horn I could shove into a heresy cab. Bob crosses his at 1200hz which was like the old econowaves. This could have been done at 500hz like bob does on his cornsclala but I was just being safe. Maybe the next version should be at 500hz. Mini cornscala. I think it’s 2” wider than stock but completely worth it. If you guys need I’ll grab dimensions for you. I love that there are no screws expect to hold the crossover down. All drivers and panels bolt in.
  24. It’s an 8ohm. Pretty much a drop in for a K22/K24. Digs much deeper
