I already have a 1-18, but this one came along for $200. Dead Mint! Couldn't resist. It is 8 ohms, as where my Sonic is 4ohms. It is more musical sounding, but not as responsive. The EV in the Sonic is a 200watter, so it is more efficient. The new Eden is upstairs with my 2-10xlt, but I plan to stack my 4-10xlt on top of it sideways next gig. Do you think it will be too boomy when coupled with the 4-10?, or just use it with the 2-10? Previously I was using the 4-10 + 2-10 stacked. I must be mental.
