After a few months with this kit I can only say good things about it.
This kit is primaly used as a bass guitar rig but honestly I never tought it woould be so good for music.
I just put some amazing music from Alain Caron ( a phenomenal jazz fusion bass player from Montreal) with about 12 watts of power ( oh yeah!!) and could feel the music from 50 feet behind a closed door!!!!
I only have good review of my bass sound ( the p-bass is unbelievable!!).
This tuesday I,m gonna try it against a 810E from ampeg and I'm really confident that I will put this cabinet to shame !!!
I will let you know more next week.
By the way one question: is it true that from the charts the T39 30" with 1x 12" gives a similar output response than the T48-18" with 1x12".
