Tekton Double Impacts

That's my understanding also sbayne. Using low mass drivers to deliver sound with much greater speed and control is the main emphasis of the patent, not the drivers themselves. 

Powered subs in the DI's? You must like bass 😛 That's a scary but cool thought.  I'm sure it would be interesting hearing the likes of Jupiter or Duelund caps but I imagine Eric would have incorporated them in the Ulfbehrts or SE as the PMD line is his "cost is no object" line.......or maybe he is, as I have no idea what caps are in them!

As one of the few people who have heard the DI SE version I must say 

Was just wondering if anyone reading this thread has any experience with the Theoretica Bacch 3D playback system?

Not sure what happened but the speakers have a wonderful and alive midrange that are quite enchanting. The speakers completely disappear and they image like crazy! I heard them at Ezra's with Teajay, Mike and Alan. As good as as the original Double Inpacts are (and they are very good!) the SE version are a bit more refined with a warm and organic midrange. They also image better. We heard them fresh from the box so I am anxious to hear them with a few hours on them. 

On on another note I must add that the Ulfs are incredibly huge! I have a picture of Teajay standing in between them with him being dwarfed by the Ulfs. I like large speakers but as good as they sound, they will not be everyone. For me the DI SE would be the sweet spot both financially and from a size perspective. In addition you can use a 2A3 single ended amp with the DI SE. For me that would be a central reason to go for this speaker over the Ulf. The 2A3 amp really didn't do the Ulf justice. Anyway, I would like to add that all these speakers do an amazing job for their relatively real world price. I have seen many speakers come through Teajay's sound rooms for review and from a price to performance ratio there is nothing even close to these speakers. If these speakers had a more advertised name they would be many times more expensive! To think you can have a great system with the microZOTL2 and the DI for less than $5K is truely amazing! It is a great time to be an audiophile!

Baranyi , I told my audiophile friend the same thing, it’s really great time to be audiophile , so many selection and good products , with a reachable price....Iam greatful....
