i picked those up last night for 10.00. the surrounds were gone , i was pretty much counting on that,i called the seller and asked the condition and she said she had no idea ,she had only used them for end tables. so i took the chance and drove an hour and fifteen minutes to pick them up.i got there and the one cabinet had water damage on the bottem but what the heck for ten bucks.i also picked up a technics sl p500 cdp for ten bucks,works great. i hooked up the mach 1`s this am and 1 tweeter is not working.can i find a replacement tweeter for these ?these are going to be shop speakers at work so is it worth the time and effort to refoam if i cant find a replacement tweeter ?
