I have an unloaded EV TL606 speaker cabinet that I would like to get fitted with a speaker. I know I can't just put any speaker in there, but don't know enough about the science behind cabinet design to choose one suitable! From what I have heard from folks is the Eminence legend CA154 speaker is a good drop in speaker for this cab. Although the sound of this speaker fits my tone, I'm a bit dubious that it will sound any good. Does anyone know if a) this speaker will not sound like a piece of crap in this cab, or b) know of any tested drop in replacements?
