tweakk, what size cap did you use with that horny ribbon ?

That transmission line cabinet doesn't look like it will be very effective as a resonator, because there is a possible path that a pressure wave could take through the enclosure that would almost be a straight line, due to the way the folding is done, and the fluid flow (airflow) will naturally try to follow the path of least resistance, so the line will behave like it is much shorter than what was probably modeled in Hornresp. The pieces that make up the TL labyrinth look more like reflectors than flow guides. I anticipate this design will need lots of stuffing to perform optimally.

Beautiful enclosure, how do they sound.

I just bought a pair of Betsy K (they will be shipped next Monday) so I'm looking for some feedback on the sound if you can.

Thanks in advance,

I think the posted graphic from Paul is more correctly a labyrinth. It reminds me of Lynn Olsen's Ariel in that it uses "offset" bracing or shelves to create it.

I would suggest considering the Demetri MLTQ from Planet10. I built a pair used with 8" FR drivers. It is very good, although a little large. In my case the FR still needs help from a decent tweeter. I have some Silverflute YAG 20-1/Dayton PT2C planar type tweeters that I'll add to them (simply mounted on top of the cabinets) or some Eminence 1-1/2" silk tweeters.
