el_Kabong said:Actually this theory doesn't seem to stand up if you look at the cabinet measurements on the epifani web site. In actual fact the cabinet volume per driver is almost exactly the same with the ul310 and the ul410 (about 1% difference). The ul610 has a larger volume per driver than the ul310, about 7% more.
I think a major reason for the difference in the sound is the fact that as the cab has more drivers they are further from the floor. This reduces the boundary effect, resulting in less bass and a perception of a more pronounced midrange. To state the obvious, cabs are acoustic devices. Their response is heavily influenced by their surroundings, and with bass, particularly by close boundaries, ie the floor! FWIW I greatly prefer the sound of my ul410 on it's side, it gives me the more extended low end I'm looking for. The difference is pronounced to my ear.
Anyway that's my 2c theory and I'm sticking to it until Bill tells me I'm stoopid.![]()
Interesting... I'm surely no EE. I was quoting some measurements that Alexclaber had done, and they seemed to match up pretty well to what I hear comparing the 310UL and 410UL. Interestingly, I prefer my 410UL upright and on wheels... there's just so much low end punch that comes out of that cab, I have no need for floor coupling.
I guess we all have our preferred sound. My strong desire in a cab is to have each note sound clearly, and not have that typical overextended low end that you hear with 90% of bassists out in the room IME.
