I have a line to get 2 for a reasonable price, I have an amp... any opinions on this subwoofer, what would be a good price to pay for 2 since they are not powered... also they are 10" woofers, I couldnt find that much info on them... but I beleive they are about 10 yrs old... but are in good condition. thanks ahead of time.
