so i recently picked up an AC rta. i'm getting the spl-190 upgrade to it. now i know everyone here swears by the TL setup. but i'm mostly SQ and am getting the upgrade to charge ppl to find out how loud they are. so here's my question. how big of a difference is there between the two? i've heard with the spl 190 upgrade there's a minimal difference.
