im currently refurbing a couple of cabs, and replacing main cones & all 3 tweeters at the same time, i've just look through some through some docs that say you should have a limit resistor inline between speaker input and tweeters the actual line says, "Limit Resistor" " No Limit Resistor Should Be Required With Amplifiers Up To 100 Watts, Use A 1K Resistor For Amplifiers Up To 250 Watts."
well what resistor do i need inline with amps between 300 & 500 watts a side, at 4 Ohms.
im asuming it's to stop you blowing the tweeters by sending too much voume through em, the cabs that are being rebuild are tsx-12's
excuse the piccy but it's one of the standards, slightly changed design since i bought mine, which inc 3 Tweeters instead of one.
any ideas please
