i have mp-1 monitors..and i think i blew a tweater...when i monitor a guitar track..my left speaker has a slight hum...when i LIGHTLY touch the tweeter with my finger the hum goes away...i checked allmy connections...and they are only 6 months old...and as far as i know...ive never over driven them. what should i do? take them back to the store? is it fairly inexpensive to get a tweater replaced? thanks
