An Ampeg 810 sounds great. It doesn't sound like a 2X15 cab. Is it better sounding than a 2X15 cab? Does it sound better than a 2X10 with a 1X15, or a 4X10 with a 2X15, or a 18"?
For that matter, which speaker sounds "better" JBL, EV, Altec, CTS, Eminence?
The 70's era SVT w/ a matching 810 bottom is arguably the best bass rig ever made, and a lot of very knowledgable people don't think there is any argument! The same argument can be made for Sunn, Hiwatt, Reeves, Marshall, etc.
DIFFERENT yes, but better......I would say "better is in the ear of the beholder"
I still want to know why you should never even consider buying hartke anything...
