crossover question

FM Former Member
i recently recieved a pair of old speakers from an old friend and he said that they didn't work and that if i could fix them that they would be mine. so i tried em out and i got some sound outa one. so then i messed around with em for a while and i got them both working...very awsome bass. but i noticed that nothing was coming out of the tweeter. the 8 inch mid range was takin all of the high ends and the 12 inch sub took the low end and they were sharing the mid frequencys. so i was just guessing that it is the crossover that is shot. but i don't know. if it the crossoer i'll replace that and see. but if it is the horn, then i'll replace that and see. but if anyone has any input that would be greatly appreciated. oh ya, by the way these speakers are like 25 years old and they were free, so i don't really mind if i break something on em. so gimme some crazy ideas. thanks a ton

Borris it's very hard to break a passive crossover built into a speaker unless you do something really really stupid. My guess would be more likely a tweeter failure but then again considering the age of the speakers there could be several options of failure there; look at all internal wiring, dry joints on the crossover PCB, leaking capacitors in the circuit, oxidized connections and or all connections leading to the tweeter. Good luck.

OK these are 20+ year old 3-way speakers. May I ask if they are pro speakers? Are they E V 1503's or 1803's? We have 5 pairs of the 1503's and 2 pairs of 1803's purchased between 1983 and 1992. I just ask because we had to replace the crossovers on all of the ones purchased before 1992 (the non ER versions).

traynor is the name. they are more like 30 years old. but anyways, i tested to horns, they are good. i checked all the connections and everything is solid. so my last guess is the crossover. if i was to get a new one, what should i look for, they are rated at only 100 watts(these are just for my home use) and 8 ohms. so should i simply get a crossover rated the same?

It's what makes up the Xover. Capacitors and Chokes. Capacitors are the little cans that have 2 wires sticking out of them. Chokes are rings of wire wrapped in a circle. the better one have a hole in the middle(air choke) the cheaper ones are wound around a metal bar (ferrite chokes) bad Caps usually are swollen or blown up like a firecracker.
