Alpair 7.3 HT
6 Attachment(s)
Hey guys, I finally finished my HT setup and was going to post some pics. I used the Mark Audio Alpair 7.3 driver in all the speakers. The center and surrounds are sealed in 6 liter enclosures, and the mains are Bi-pole MLTL towers. Scott was nice enough to help my with the design of the towers, they sound wonderful...

Excellent, nice to see those ML-TLs happening. The room is a bit sparse. And given that it is an HT, where is the TV?

Ha ha..One step at a time... Furniture and TV hopefully coming soon. For now, its just a listening room. The mirror is temporary, hiding wires....

Well you got a good start. And much more useful than a TV with built-in speakers :D

Very good looking HT build... and with Alpair 7.3 in Scott's designs, I am guessing they sound really good too. :)

I notice the subs cones are different - or am I mistaken?

tell us about the bass traps and wall treatment

nice cabinet work

The subs are both sealed units, one a SEAS L26ROY and the other a DAYTON. I'm in the process of building two new ones using the SEAS L26ROY sub with passive radiators, they will crossed at around 100hz with the Alpairs...

As far as the bass traps and wall treatments... I did a lot of research on this subject and wanted something simple to build, low in cost, but with good performance... I'm sure their are better options out there, but I'm really happy with how the room acoustics turned out..
In the bass traps I stacked acoustical insulation and covered it with cloth. I think they call it "super chunk bass trap" on the net...
The first reflection panels are one sheet of the same insulation, (3inch) covered in cloth with a 1 inch air pocket between it and the wall..
Both projects were really simple builds, cost effective and work well for me...

A snoutspankingly attractive setup. Well, insofar as speakers can be anyway.

May I ask what is the point of building a large twin driver MLTL, if you are crossing over at 100 Hz. A sealed box with single driver (like your surrounds) would have easly got down to 100 Hz in that room. Did I miss something?
