Just wanted to run this by you guys to get some opinions. I'm still in the thinking phase of what I want to do. First, my current rig. Alembic F1X and a Stewart World 2.1 with an SWR Goliath jr. 2X10 and a Big Ben 1X18 Bi-amped Some of the problems that I faced with this set up was the rear ported 18 being troublesome in some rooms. In smaller rooms, the 2X10 alone sounded very thin, lacking mids. So I would always bring the 18. I could always get a good punchy sound with them together. Basically what I want to do is down size, but I am also looking for a modern sounding system with tube warmth. My first thought was to just change out my speakers and I was thinking about going for the sound and punch of a 4X10, specifically the Epifini UL410. With their reputation and portability it sounds like a no brainer to me. What's your opinion on the Alembic/Epifini set up? I believe that a pre-amp speaker combination is important. They have to be a good match. Just because they are both great equipment separately does not mean that they will be the best match. I have read comments here that the F1X lacks mids and sounded bad with the scooped mids of a SWR 4X10's I did not find this with my bi-amp set up but did with the 2X10 soloed. I guess my fear is that If I got rid of my SWR's and got the UL410 it would not be as good. If the F1X is not a good match for a 4X10 I would like to know because none of the great speaker companies have dealers in my area. So trying before buying is not an option. My second thought would be to go with a Demeter/Epifini set up. Experiences and suggestions would be appreciated. Thanks.
