I very much appreciate your comments on my DIY build. These are my first attempt at building speakers from a kit. I have my TRT's about 3-4 feet out from the back wall and maybe 2-3 feet out from my side walls. They are rear ported, however, if you read previous threads on the TRT, Rick specifically states that a sealed version can be built as well. I am driving them with tube amplification (KT-88's) and the bass is very fast and accurate.
The AirCirc Tweeter is great as well. This is a very non-fatiguing sound. I can actually crank up the sound for different genres of music and keep it there for extended periods of time. I also like the sound when I have to have low volume listening sessions.
