Just read a review on an expensive T line speaker in Stereophile. There is a lot that I missed about T lines and never built one for myself. Anyway, I just know that the model was named Adam. Funny as it might sound, they thought the bass was too much. Not bloated, not distorted or any of that, just too much. The manufacturer suggested putting them up about 7" from the floor, but of course that creates new problems. Personally, I would really like such a speaker, and coincidently I presently have a speaker, that although not a t line, gets great bass. Finally, the right bass for me. Still, it wouldn't surprise me if I were to build such animal in the future. Read the Stereophile review. You will like it.

 Doug,

Funny you should mention that. While using the DNA2 cabinets with Scan Speak drivers, I am almost in the same ballpark as you. Thing is, I felt cheated in the bass department for a long time, and so at first the SS were incredible sounding. They have everything that I want, but maybe just too much of it. Of course, I could cross them over at about 80hz and go to a sub, and that may be a better way for me. Running them full range without a sub gives me less control that is for sure.
