Over the last couple of weeks I have built a couple of prototypes of the Version 2.0 Neo 3 Wave Guide that Danny B. has been testing in California. This pair is for my R&D efforts centered on systems using Purifi PTT6.5 woofers. These protos are cut into Balticbirch plywood and sized to match the Fi16 enclosure featured in my PTT6.5 work.

Version 2.0 Neo 3 Wave Guide CNC cutting completed. BTW the large V-cut bit shown was only used for the edge chamfers. Wave guides were cut with ball end mill bit.

The state shown in the last pictures was achieved at about 10 PM last night. Initial listening to uncalibrated bi-amp system with 2A3 SET amp driving the Neo 3 + wave guide and ACG 1000 Icepower on the woofers. Preliminary listening session at don’t-wake-up-household levels is WOW
. If it sounds this good with the Neo 3s taped onto the baffles and levels guessed at it is quite exciting what is in store as mechanical, finishing, and acoustic refinements are brought to the prototypes.
