SWR TRIAD 15" SPEAKER IMPEDANCE.

I have a Triad. Why are you replacing the 15 speaker? If the voice coil is blown, and that's the reason you're replacing the 15, that is a problem. If the voice coil is intact, you can measure the DC resistance of the coil and derive its impedance: for example, if the voice coil measures @ 2.8 to 3.5 ohms or so, it's a 4-ohm nominal impedance speaker.

Also, this blog link has a pdf (about half way down) of the circuit in one of the postings, which indicates the 15 is hard wired full range. That would also indicate that the 15 is also probably a 4-ohm driver.

Unfortunately, it's not quite as simple as simply picking a 4-ohm driver. The power rating and the compliance for the size and porting of the cabinet are also important.
