  1. Spent a full weekend ripping wood for a pair of cabinets. Plan is to augment or eventually replace a pair of Keystones. I've always been a TH fanboy but I trust that if Ricci thinks bandpass cabs are the business then I'm eager to give it a go. Looking forward to that sweet 30hz.

  2. Hi everyone! I'm new to this forum, after beeng very active on different forums here in Norway. Over the years I've built and restored about 200 different cabinets for speakers in my small workshop, and my latest one is the Skhorn. I've also built six Othorns, but these Skhorns are among the largest cabinets I have done. I built three, two for a customer and one for myself. All the parts are cnc'd out of 18 and12mm BB at a friends workshop. I think the build was relative easy compared to the Othorn. I'm going to use the Ipal driver, and will start testing tomorrow with a Crown Itech 6000 am

  3. Excellent work. The response looks very good. No surprises.

  4. And here's some measurements (with UMIC1 and REW): Red: All six ports open Green: Two ports plugged Blue: Four ports plugged No EQ was applied here.

  5. Chiko, I'd suggest putting some damping in there behind the drivers. It should clean up the top end a bit and "tighten" the sound.

  6. I finished a 6Ch amp build made from two Hypex FA123 yesterday. It's a lab amp for speaker testing, so it has all connections on the front. It's not the prettiest and already has a bunch of scratches, but hey, at least it's got cable management..!

  7. I don't know if you saw my skram built on page 26 or so, I built 2 of them, made of popplar plywood with a carbon-epoxy layer around to make it stiffer. Then we made the front out of 25mm transparent acryl glass, just to loose the weight savings due to the 10kg (just a wild gues, I forgott the real numbers) of those fronts haha. We didn't put them on a weighting scale yet, but without the heavy front, they would be ridiculously light! So light that we will make a base filled with sand to make sure they dont move more than the drivers do. We also didn't fire them up, but that will happen s

  8. I've noticed something very interesting I wouldn't have believed was true when experimenting with my Hypex amps yesterday. These amps needed to be "broken in" with a high level signal or they'll run at unusually high distortion. Sounds like snake oil to me, but heres what I've seen from the data: General info: -Sweep of the audio interface max 0.005% THD 100Hz-24khz (sweep went to 48khz) -THD somehow off rising to 1% at 20Hz (has been RMA'd once, guess it's still slightly damaged) -THD numbers in the following paragraph are mostly constant through the frequency range, so I'm picki

  9. Thanks for doing this! Those CVR amps definitely look attractive from a value perspective. It's nice to know your doesn't run like a furnace. Amps typically sound very similar when operating within their performance capabilities. However, differences are still possible for a few reasons: Amps typically use a high-pass filter to protect them and/or the speaker(s) from inaudible DC signals, and they vary a lot with regard to where the HPF kicks in. However, most amps don't start rolling off until 20 Hz if not much lower. This is something that should show up in the REW measurements if
