Cheers, Alex
Alex you do absolutely beautiful work. Do you make the butcher block? I just love this look it beautiful!

WOW! I just checked out the thread and I'm even more impressed now than I was before! You are a very talented speaker builder my friend. You should be making and selling those awesome speakers!

My lastest project. Eminence 12LTA + Visaton TL 16H in a 165l BR tuned to ~20hz. The cabinet is "BBC/Harbeth-style", ie. made lossy and unresonant with 15mm birch ply, heavy-ish bitumen damping and lossy coupling of the baffle to the frame. Structural/decorative paint also offers some damping. 12LTA is slightly modded and is current driven (with step-up transformer and series res).
(DCX2496 is not in use, only the super tweeter has some xo'ing.)

Hi Legis!
I'm curious, what make & model are those two amps on the top shelf of the rack in the photo I included?
I'm listening to: Premonition by Paul McCandles
The amps are chinese made ShengYa PSM300 mono blocks.
I actually got them ready today, they sound very nice. Luckily the drivers are already broken in in the previous setup, which was narrow baffles. I have a feeling I wont be doing normal enclosures anymore, except for subs 🙂. Midrange clarity and intelligibility is very good with a lossy cabinet. Bass is tunefull and timbre-accurate. I will be doing some measurements and fine tuning tomorrow and onwards.

^Just for clarification, normal enclosure = an enclosure with thick/rigid walls. I WILL be doing lossy cabinets from now on, no more thick walls except for subs. 🙂
I thought maybe you used the bezel cover, but I wasn't sure due to the bevel! Great idea! Thanks for that!
Birch ply, thickness 10-15mm depending on the cabinet size. With these 165l (un-supported) cabinets the 15mm was good thickness. Too thin walls (compared to the size of the cabinet) will damage the bass dynamics and tend to sound "woody" in general, ie. color the sound by resonating too much. On the other side too thick walls cannot be damped adequately. Still I would err on the too thin side. 🙂 Naturally the best compromize is the thickness that is thin enough to be damped completely but does not sound woody nor affect greatly to the bass dynamics. Harbeth succeeds in this in their smaller monitors IMO, their big monitors like 40.1 tend to sound somewhat woody in my experience.
Interesting reading regarding lossy cabinets vs. thick-wall cabinets, and birch ply vs. MDF: http://www.tnt-audio.com/clinica/cabinet_walls_e.html

Just a simple hack on a Voigt tube plus a 500Hz tractix horn with a inexpensive speaker:
Works surprisingly well. I guess is time to build two with better drivers.
Cheers.

Made a quick video with Galax S4, "hear" for yourself heh 🙂.
