Bandmaster Cab. 4 ohms?

[silvergretsch]

This is a 4 ohm cabinet, right?
Bandmaster 2x12 cab:


How about this one?
Musicman 212 RH One thirty:


My amp has 4, 8, and 16 ohm outputs.
-thanks

Can't tell by looking at the box. The easiest way to tell is by plugging a speaker cable in and using an ohmmeter to measure across the tip and sleeve. A four ohm cab will measure a bit under four ohms, an eight ohm cab will measure 5.5-7ohms. Second easiest is pull the back off the cabinet to look at the speakers and wiring.

Purely a function of what drivers are in the cabinet. This cabinet, stock, was 4 ohms - two 8 ohm drivers in parallel.

[silvergretsch]

Its stock. thanks. The Musicman cab has 2 different speakers in it. I'll try to open it up.

hmmm....

I have a 2x12 bassman cab that I could have sworn was 8 ohms...

[silvergretsch]

Isn't this a car stereo speaker?

Here is the other one:

I had a couple bandmasters 30 years ago and I'm thinking they are 8 ohms.

It don't matter since your amp supports several impediances.

Hey does anyone remember the old West amps?

[silvergretsch]

The speakers look like this.

Numbers.

Also, what would happen if i took some or all of this padding out?

[RandyW]

Those don't look anything like what I recall being in my band masters. I know for sure mine did not have square magnets on them. I believe mine were manufactured in the late 60's so they could have switched manufacturers.

I do recall that there was a huge amount of screws to remove to get the backs off. And in those days they didn't have electric screw drivers.

[silvergretsch]

according to this guy they're 1969 and 1970 CTS part #'s. And I think it was only 130 screws to get the back off, and my electric screwdriver lasts for about 1 minute between chargings...

Well if you want to know for sure what the ohms are just do what the other guy suggested and measure the resistance at the speaker jack.

Do you have the head for that amp too. I sure wish I had a few of the old tube amps I use to have. ;(

Or since it appears in the pick their wire in parallel you could measure the speaker impedance and divide by 2.
