Somewhere on one of the forums where the new TC site was announced, the company representative indicated that they would be offering the components to the DIY community, the ribbon offered in full length and shorter versions as well, IIRC. I'll try to find the post.I am considering line arrays for my HT room mounted in wall. The BG's are cost prohibitive. I hope whatever TC offers might be more favorable. If you interpolate the products shown on their site I could see the tweeter and mid unit wall mounted with their 3" depth subwoofer mounted below it as having high potential for an exceptional T set up. I would think that line array attributes would translate well to the typical HT listening room. I remember distinctly how musical your line arrays were even from te next room and how close proximity to one speaker doesn't negate the output of the other speaker. This characteristic especially I think would mean that an entire HT listening room within a near field environment would provide a very natural and realistic experience. Another posibility that is intriquing, would be to use te space available between the studs in an inwall application for a transmission line enclosure.
I'll have to come check out your new additions. I really appreciated your hospitality and patience.
