Ohm question...

[Bfeeney]

I have a Blackstar HT-5H head and two 1-12 cabs, one without a speaker. I am going to do two 16ohm speakers to make 8ohms. My question is that I found a Celestion G12-65 that is 15ohm, could I have a 16ohm and a 15ohm speaker and be ok plugged into an 8ohm port?

Re: Ohm question...

If I'm not mistaken 15 ohm Celestion speakers were common in Marshall amps and I think they were treated like a 16 ohm.

Close enough for rock and roll.

I asked Celestion almost the same question. Here is the thread with the answer I got:

Hi,

I was just wondering why the Heritage Series G12H(55) is offered in 8
and 15 ohms, while most all other Celestion speakers seem to be 8 and 16
ohms?
What does that 1 less ohm on the 15 ohm version do for me?

Thanks,
Kevin

Hi Kevin
Absolutely nothing. Back in the day the standard impedances
available were 8 and 15ohm. In the late 80's the industry standardised
on 16ohm and all the labels changed but the actual speakers were not
changed a bit. The numbers are 'nominal' and there was no difference
between the 'actual' impedance of a 15 or 16ohm speaker. For marketing
reasons the old style speakers get the more authentic 15ohm number but
really it just causes lots of questions like yours!

^ +1.

There is absolutely no problem using the 15 ohm spkr as if it were 16 ohms (which it actually IS).
