Finding ohms of a cabinet

Sign in to disble this ad
I have a speaker cab I thought was 8ohms (that's what I asked for). But I finally noticed a tag on it that says it's 4 ohms.

Is there a way, without taking the drivers out, that I can know what the ohms of the cab are? It's 2x12 with a 6" and a tweeter.

I've run it in parallel with another single 12" 8ohm cab for over a year. Sounds great and doesn't cause the amp any issues (Carvin bx1200 in bridge mode).

You can use an ohmmeter to measure the DC resistance of the cabinet. A reading of 3 ohms or so would indicate a 4 ohm cabinet. A reading of 6 ohms or so would mean it's 8 ohms.

Hope this helps.
