Two different Danny’s, oh this could get confusing. Oh well, thirty years ago I was part of an engineering team with five
different Mike’s and Michaels’s. So I suppose we can keep our Danny’s straight.
It’s been great fun helping Danny Badorine
with the 3D CAD and then CNC machining on the baffles for his project being discussed here. This fit perfectly into a project I had running to develop a wave guide for the Neo 3. Danny B and I agree that once results warrant the better of these wave guides should find their way to Danny R at GR World Headquarters. For now I am adding some pictures to aid this discussion, and because this is the internet and we all know without pictures it didn’t happen.
Version 1.0 featured a round 6.25” diameter wave guide the design I had cooking when Banny B’s project popped up on AC. It curves up the wage guide from a start in a circle and reliefs around the Neo 3’s output slots. This wave guide is on the baffle discussed above. Both versions differ from GR’s in that they are deeper using two layers of 0.75” MDF to get a wave guide 1.5” deep. Danny Badorine and I share an interest in increasing the depth in search of better time alignment yielding one hopes a simpler crossover.
Version 2.0 which Danny B just received yesterday features a rectangular 5.4” x 6.35” waveguide with straight flare dimensioned for equal distance from the Neo 3’s slots to wave guide end. I will not take offence if similarities to prior art by Raidho and Boerresen are noted. Also will not take offense if someone wants to sponsor a set of Børresen 01s or 05s to use as a benchmark for this project. Let me know if you’re feeling generous and I will get you a shipping address.
Finally as a bonus question, who can point out the CNC machining mistake on Version 2.0? Hint, an end mill took one for the team.
