Hi i have a pair of tower enclosures that need new midrange drivers they are a pair of 3 ways towers .. they have dome tweeters in them that are fine but i killed the midranges some how .. and on one of them the midbass driver cutz out but i put a peice of tape on the lead from the connector to the coil it works but i plan to replace both midranges and midbass drivers on them and leave the original tweeters ... my question is how do i know what drivers to buy that would sound the same as the orginal ones and im also having a very hard time finding 4.5 inch midranges ... i would just have replaced them a while ago but cant find any so i run them currently with out midrange. ok ill get to my point i would liek to replace the 4.5 inch midranges and 6.6 inch midbass drivers in my towers. i would like to know what drivers should i buy or how would i find out wich ones to buy that would at the very least sound the same as the originals. i do have the dimentions for the towers and i know that they have separate enclosure inside for the midranges. Thank you all very much in advance for any help.
