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.

Thanks Mark!

I thought maybe you used the bezel cover, but I wasn't sure due to the bevel! Great idea! Thanks for that!

May I ask what material and thickness you will employ in future?

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.

Nice, TCA. Good work on the tractix horn.

Legis, nice to be able to see and hear them in action. Not that a YouTube video gives an accurate reproduction, but I can hear the basics and they sound great.
