Dafos, I think that the steeper slope will on some material potentially give rise to a "hole" effect. I had noticed that in a friends sub when I auditioned his system. However, that's not the reason that I went with the T5. Instead, I wanted a sub that wouldn't risk overdriving the room and one that was quick on its feet. The GH's are lighting fast in their response time and I didn't want to risk losing that magic. Even with the T5, I do feel that there is a smidgeon less mid magic in the portrayal, BUT it is made up for with the rest of the spectrum. I guess one cannot have it all! One of the things that does bother me most with other systems I have heard that use subs and minis, is any "hole" in the transition....to me that always is VERY noticeable. Luckily, after much experimentation that isn't an issue for me with the T5.
