just put in all the new stuff in my 2.3tl's, and they definitely sound a little thin. what can i expect for a length of a break-in time? at one point, i thought i heard a cackling distortion from the tweeters, but i changed the source and they seem fine now. they are too bright, and i just want to know what others have experienced. i did remove the poly's, and all parts are from sonicraft. all pieces are correct, and laid down right. what a full board!! any help-suggestions-experiences greatly appreciated. also, i do have the new rdo tweets from polk.
