  1. Dave still sells kits to build the eliptrac 400. He doesn’t offer plans. Lots of math involved between Dave and ALK to get it right.
  2. Selling my Deep Core 1800. I decided I needed another Equi-Core more. Does an amazing job. The knob in the rear allows your to vary the impedance between the ground and neutral. Think of it as a hum killing/black background creating knob. 4mo old. Looks and works flawlessly. Paid $1295. $700 obo. Justin 949-636-9076 Deep=Core removes, EMI, RFI and most importantly DC from the line. DC is a major issue and almost all AC lines have some DC on them. It also has even better surge suppression. There is also a Contour Control on Deep=Core to match the power coming from your wall to the power supplies in your equipment. You plug Deep=Core into the wall and then Equi=Core (or any power conditioner) into Deep=Core. The pair makes a world class line Conditioner with surge protection. The Deep Core 1800 is a multi-function power conditioner that re-defines the category. The Deep Core 1800 is designed to not only provide clean, spur free power but it also allows the user to optimize the power delivery interface via a user adjustment. The optimization of the power delivery interface can significantly affect sound quality as the power company is a major contributor to attributes such as poor noise floor and dynamic range of the system. The Deep Core 1800 can be used with almost any system configuration providing optimized power for both source components and power amplifiers. It will work as a stand alone device, in front of the Equi=Core 1800 or older 1200, 300 etc, or in front of any other power conditioner you may already own. However, it works best when used in front of a quality power conditioner, like the Equi=Core 1800 balanced power conditioner.
  3. Upgrading to the separates. No scratches. Flawless condition.... need to whipe my finger prints off the front 🙂 The Hint has been an incredibly good integrated for me... 1 year old. Only used to drive my Cornscalas. $1600 Shipped.

  4. BTW. Fully agree with the 45degree deflectors. Dave Harris was awesome and made for lemon request. He was super smart and back cut/relieved the inside corner as to allow it to mate even closer. I liked for the reasons of positively locating the corner, deflecting and improved bracing. We orig started with 2x2 45deg deflectors but cut down while building the cabinets to find a Vance between size/performance. The deflects can eat space quickly.
  5. Not sure. I have about 4K in there when you think soup to nuts. That’s the horns, finish work on horns, doubling baffle, cabinetry with extra time... not a usual way of building cabinets., 45deg braces, finishing, crossover, drivers. If you were just using a 2.5-3k multiplier you’d be at 12k for a pair. Now are these as good on the CW4... others would have to say. I think there are many compelling arguments both way. The CW is most certainly prettier, but this pair matches my super Heresy and my rack so it works for me. I like understated and so my black boxes are very easy to under estimate. With all that said, I have 4K in them not 12k so Is like to think it has been with the effort. mom addition to the over the top build. I got to pick the best parts I knew of. The CSW400 on paper may not be as good as my CSW450 but the lower order crossover is much more forgiving at lower volumes. For my size room and fridge this was a better choice. The DCM50s is one of the very best lower crossover point drivers without going Be... TAD os 3x the cost of the BMS. The BMS is so hard to get too. To answer the question differently. If I was asked to sell I wouldn’t consider unless it was 8K or something. Too much time invested to QC all the aspects of the build to get the level of execution I wanted. One last note. The FaitalPRO HF10AK is supposed to be amazing from friends that have used. If it’s the case I’ll replace the DE10 with it.
  6. Thank you! They sound pretty amazing. Though bit the last word in bass extension. i don’t feel the need for a sub. I have the HF sailed down but have bought a super cool faital Hf to try. If it is a bust the DE10 will stay.
  7. A pair for my listening room. Im not setup to build large runs. But this pair suites me just fine. id asking how many cornscalas over the years... maybe 12pairs... each a bit different.
  8. Final tuning: CSW400 DCM50/DE10 12,0 HF -6db Sounds great. -11db was better for voices but -12 makes feel it being more full sounding.
  9. Did final assembly. Tuning questions are left. Have the DE10 at -4 dB down. Likely to live to -6 it’s a small room and I want to be able to listen for 2hrs at a time without fatigue. Ive ordered an exceptional Faital HF that I may roll in but I intend to having tuning set for each. The DCM50 is at 9,0... the LF is a bit muted. I will switch to 12,0 and re-Listen. My Guy tell me I’ll be at 12, -1 when all is said and done.
  10. Not at all. Thanks for the kind words.
  11. Im not sure if Klipsch has incorporated deflectors as integrated bracing or dadoing. Both power on the face of it solid ideas. The 2 places I chose additional material is the back brace. I wanted more than the standard 3/4 mounting face. I have about 1.5” of shared contact face. The back board used 14 1/4-20 bolts to attach. The idea again to snuff the life out of cab talk. The other place was the double thick baffle. The idea is take. From subs I’ve seen built, and by wearing the materials between MDF and ply I should move the breakup nods higher up. I’m getting to a place here I’m less likely to be building a pair a year and so wanted one last big build. Al did a CSW which should pair well with the eliptrac and the dcm50.
  12. Also for the corner supports/deflectors have Posstive engagements tying front baffle to rear brace. In general I’m trying to reduce cabinet talk.
  13. The sides are Baltic The rear brace is MDF. Dave Cit for me and I didn’t specify. The front baffle is 1.5” thick. 3/4” MDF which is meant to provide the tightest most cohesive fit into the horns which are also mdf. The 2nd layer of the baffle in ply for added strength. The rear panel is Baltic.
  14. Slow progress but cabinets and finishing will be done by 6-23. The baffle and back brace is dado’d into place. We did a interesting thing by cutting corner braces at 45deg. Should reduce cabinet residences. Here is where we are so far. Drivers are kappa 15C DCM50 and radian 1” for once I’ll have a tweeter that can really carry to 20K.
  15. It’s likely putting out about 5watts. It’s likely enough to thunder a pair of cornwalls for sure.
  16. 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. $1600 Justin 949-636-9076
