That's a pretty sexy looking array. Well done!
Is that veneer a Pelin Burl?

Bob

No veneer, it's local birch plywood (2x24mm all the way), stained with water based dark mahogany and mildly french polished with amber shellac.

 

[Bob in St. Louis]

Wow, that's some very nice plywood! You're lucky to have such a material.

Nice sraudio. How would you define the sound character?

As engineer I think it is not very wise trying to describe the sound character, but in a few words it is very dynamic and natural.

Here's some of my OB's projects, Electrovoice SP12B and SP15 and PHY-HP.
Enjoy!

My OB w.i.p.

Here is my latest. Not finished obviously but sounding very very nice. The tweeter is currently on the rear (wanted to audition for a while before cutting holes) The phase plugs shown are only temp. Waiting on the return of more favourable weather to finish.

What drivers are you using Kendt?

I used a pair of spark plugs for phase plugs once in a test/comparison and they did almost as well as real phase plugs.

What was the gap set to djn?

I ground the bottom down flat so it would grab the magnet. I will try to find those results on my old computer and post them. We where all very surprised.

eminence 15a,s for bass
hivi planar tweeters
selenium 10pw3 on mids

the system uses two charlize 2 amps w/mini dsp.
The 10pw3,s sounded absolutely awefull at first and went back in their boxes several times but after a few tweeks and a ton of breakin they now sound surprisingly good. Patience paid off bigtime here.

What kind of wood is that?

 

[puppet]

Looks like maple.

 

[SpinMonster]

Hard to cut

Wood is European Beech Fagus sylvatica - Wikipedia, the free encyclopedia

Are side wall reflections bad for a dipole's rear wave? If a speaker is towed in a bit to the listener, it seems it would be an issue.

 

[lolo]

that's one for Rudolf!! 🙂

Master, you summond me?
If wavelength are short compared to the room dimensions, a dipole will radiate in its dipole-8 pattern - regardless of the side walls. Reflections off these walls will be as good or bad as with any other loudspeaker.
If wavelength are in the same order as the room dimensions or even larger, the "radiation pattern" will be dictated by the room (room modes), as will be the case with any other loudspeaker.
So what seems to be an issue to you exactly? How would you see off-axis reflections (?) more harmful than others?
