Thanks for the quick replies guys, very informative. Seems like I'll have to be like all the others, and swap out speakers over time to find out what I like. Its the journey, not the destination.
@Tig: That Eminence sounds killer, most definitely an option, and the price is nice too!
I'm leaning toward getting a comparable speaker to what Boogie uses in their Thiele cabs and start from there, since their Thieles are based on the EV TL-806 design anyway (Thanks Tung!). Mods, if this belongs in another category, please move it. Looking forward to any other suggestions...
