Im impressed with the output and efficiency. A row of 8's or 10's with an RD 50 may be the way I go.

What 8" driver is that? What are the specs (Fs, Qts, Vas)?

Thanks for sharing the results.

Yep they are very voltage efficient, I have wired arrays to 3.2 ohm nominal impedance. The driver is Gradient Axis AXT-08, basically paper/kevlar cone version of the Dayton Audio RS-series with a slightly smaller xmax(I think it's smaller). Driver has been tested in 2011/3 Klang & Ton. Basically an accurate and punchy woofer with high sensitivity, low moving mass, strong motor and high Qms. Efficiency is about 92dB/w, qts 0.3, Mms 21 grams, Vas 50l, Le 0,4mH, voice coil diameter 39mm, xmax around +/- 4mm (+/- 5,5mm mathematical/realistic).

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

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

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

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.

Default 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.
