Need info on some white van speakers

[John Warosa]

I know it's probably a bad idea but I want to turn a pair of Acoustic Lab Pro Series 710s into one big speaker cabinet for my bass guitar. My idea was to wire the two systems in parallel and make a big box to boost the bass, but my main issue now is that I don't know the rated wattage of the speakers. I would like to use a 300W amp head to drive them, which is believe is possible because the Pro Series 600s are 175 each, but unlike the 600s, the 710s that I have don't have any info on them (I had to use a multimeter to find the resistance). I know it's a long shot, but does anybody know the rated wattage of the Pro Series 710s? Or do you think a 300W amp will blow them?

Building speakers is a little more complicated than building a box and dropping in some drivers.

Musical instrument drivers are typically built to a much more robust standard than something you salvaged from a pair of white van specials.

IMO your time, effort and money would be better served buying a speaker better suited to your purpose.

Don't waste your time. Plenty of cheap bass cabs out there.

You will have less issues with a large amp. The danger usually is that small amps get pushed into clipping range, which distorts the signal into a square wave. This is what will damage the speakers. If you are trying to determine the impedance of the speaker, just using a reading of the resistance does not accomplish that issue. There is a formula that is used. I don't know that formula, but it can be found somewhere here on AK.
