I just finished building these towers for my hifi system. The design is from Bill Fitzmaurice, and is called the TLAH. The TLAH combines the features of a line-array, transmission line, and horn loaded enclosures. Each tower contains 9 4" mids and 12 1/2" tweeters. The top of the cab is open, creating an 80hz tapered transmission line. They are designed to be placed with the port against the wall, for a sort of horn loading effect. This helps them maintain 99dB efficiency down to 80hz. I burned through the paint in a few spots (which I'll fix later), but otherwise they have a mirror finish that took days of sanding. I am very happy with my entire system now, it can get obscenely loud with absolute clarity (each individual driver is barely moving, so very little distortion).

The entire system:

  • Thorens TD166 MkII
  • NAD 1020 preamp
  • Hafler DH-200 (100W x2 @ 8ohms, 200x2 @ 4ohms)
  • BFM TLAH towers
  • Dayton SUB-1200
  • Entertainment center is built from 1/2" threaded rod, floor to ceiling, not attached to any walls

Is your screen name inspired by Brazzers?

Not sure if it's from Brazzers, they are really old, but I think you know what vids I'm talking about.

If anyone could fix the pics I'd really appreciate it. I can't figure out how to post the imgur album and lost the original page with the other links on it.

Got, thanks.

I agree, they are quite sexy.

Another benefit of the line array is they sound absolutely massive!!! They present much more of a cylindrical wavefront than standard single driver setups. I also have the equivalent of a 12" mid in each of those towers, so gobs of cone area. My listening room is only about 10x12, so maybe a bit overboard, but I listen to mostly doom, psychadelic, and sludge metal, so there's no such thing as too big and loud!

I mean, line arrays in a stadium are nuts, I can't imagine them in a tiny room like that.

Any sort of acoustic dampening in the room or is it just four walls?

I've got a bit of foam on the rear wall, and a lot of plants (which seem to do a decent job of dampening), and a lot of wall shelves (which help with reflections), but nothing too intensive for sound treatment. The lines themselves are damped internally to kill harmonics.

Honestly though, the lines can completely overpower any sort of reflections or room effects. At my seating position I am well within the "near-field" of the lines, like you would be with studio monitors.

Awesome. A lot of what you're talking about is over my head, but I know enough to appreciate the depth of your knowledge.

The speakers look amazing, excellent craftsmanship.

Are there any crossovers involved or does the enclosure take care of that?
