speaker impedence
does anyone know what the impedence of a speaker would be in this situation: its a coaxial with an external crossover. with the crossover hooked up it is a 4 ohm speaker, but if i were to just wire up the woofer part (not the tweeter) to an amp without the crossover would the impedence be 8ohms? or what. thanks

Re: speaker impedence
The crossover will not add any resistance to the speaker. So if the speaker is 4 ohms it is still 4 ohms.

Re: speaker impedence
ya but a coaxial is essentially two speakers (tweeter and woofer) wired parallel. so i think it would be an 8 ohm woofer and 8 ohm tweeter and where they meet, at the crossover, it becomes 4 ohms. i dont know if this is true because i dont know exactly how a crossover works but i would assume if it does not affect the impedence( or at least not significantly) than each part of the coaxial would be 8ohms. is this correct

Re: speaker impedence
That sounds a little fishy. If I'm not mistaken, a crossover won't significantly affect the rated impedance of the woofer. Essentially, you should have a woofer and tweeter with the same impedance ratings. When they are attached through a crossover to the amplifier, the amp sees them as being the SAME impedance that either one of them is. For example, if you had a 4 ohm woofer and 4 ohm tweeter connected through a crossover network, the amp would see a 4 ohm (approx) load.

Re: speaker impedence
that would mean that the crossover itself effects impedence, because if u eliminate the crossover, u are just wiring two seperate speakers into one channel ( parallel) and if they were both 4 ohm speakers wired together would cut it to two ohms. this is where im unsure. i dont know whether the crossover effects impedence or if both speakers are 8 ohms so when they are connected to the xover its 4 ohms... thanks for your thoughts at least but im still not sure ha. its not a big deal anyway i think i decided to just wire it with the crossover and tweeter. thanks for ur time tho guys
