+10! More clarity, esp down low, has shone a brighter light on my weak technique

......but makes me work harder and focus more.....at least until the 2nd bourbon seeps in
These comments are interesting. I actually found that the 12/6 and 15/6 designs that I've played are much more forgiving of technique flaws. These cabs have a much more relaxed tone in the low mids, and also in the upper mids, than many of the more traditional 2 way neo loaded cabs out there now.
What previous cabs are you comparing these designs to? I guess if you were playing a low quality 215 or something, I could understand this. However, if you want to put really put your technique to the test, try a Bergantino AE cab, or any number of high quality 112's, 210's, 410's and 212's.
I also had another of thousands of typical experiences last night, listening to a more traditional cab at an extreme off axis listening position (about 70 degrees off center, and about 50 feet away) in a club (a nice little Hartke two way 112), and the tone was even, full and articulate from the lows through the mids, all they way up.
I guess I must continue to live in an alternative universe from some of you guys. I just don't get it.
I like the 15/6/1 build quite a bit, but 'it is what it is', and has its own tone profile. Like any other cab, you can EQ it to move that inherent tone profile, but not by that much to my ear (given the typical EQ profile of most bass heads), at least not any more than moving the inherent tone profile of other high quality cab.
