Default Herbert Jeschke's TQWT with RS 40-1354, dimensions?

I have 2 RS speakers laying around and ready to cut wood, I like the picture of the TQWT.

Is there a detailed size information on this? Anyone built one?, will drive it with Sonic T amp.

Amen to that. Avoid the Lowther Club of Norway Voigt Pipe (which is what this is) like the plague. If you want a TQWT for this driver, just build Bob's Straight Pipe cabinet and have done with it.

I agree. I dont think you are going to find a better design for the 1354 than Bobs. I built the folded version and it sounds excellent. The bass response is really superb for a little 5.5" driver. Easy to build and proven design.

I dont use BSC since they are up against the wall in a small room.

Thats a small Infinity tweeter (generic 3/4" ) w/ 2uf cap mounted in a hardwood block. It can be aimed any direction and my currently its towards the ceiling.

Don't remove the dust cap unless you plan on installing a phase plug. The phase plugs on my Radio Shack 1197's really improved the sound quite a bit, but I'd be reluctant to just open them up without a phase plug. The link that you provided is, in fact, how to remove the dust cap. but is only the first step. At the bottom is the link to how to install phase plugs.

The Planet 10 Phase Plug is a quality product that can actually improve the sound of your system and is probably one of the greatest "Bang for the Buck" improvements you'll ever make in your system.
Best Regards,
TerryO
BTW: I know Dave, but the plugs were purchased at the retail price. I'm just a very satisfied customer.
