Right now, I'm rocking out with 2 410XLTs, and while they have the volume (and boy howdy do they) I keep wanting a bit fatter bottom. And by a bit, I mean a lot. So I'm looking at 18s to beef up the low end. Now, I'm kinda torn, mostly due to the sound applications. On an 18, the sounds project out like 20/30 feet, which means that near me, I won't be able to EQ it all that well, but at the back of the joint, things are jumpin like Jack Flash. I'd like to be hitting everyone at once though. Is there some way to "cure" this? Something that can be done, be it putting the cabfacing the floor, or behind me, so the sound reflects off the back wall, or anything? Pretty much, I want the boom without the hassle. Or would I just have take my lumps with an 18? I'd think about a 2x15, but those are always 4 ohm cabs, which would mess up the impedance with a 4 ohm output and an 8 ohm 4x10 sitting on top. Any suggestions/help? Lookin at the Eden 18XLT btw.
