Extension speaker?

[Jack Francis]

I have a Fender Twin and 2 speaker cabs.

One has 2-12's (4 ohms) and the other a 15"
8 ohm celestion speaker.

When using both cabs which one should be used as the "Extension" speaker?

It doesn't make any difference to the amp, since the jack just "parallels" the two loads. Since the 15" cabinet has a higher impedance, it probably won't sound as loud as the cabinet with the two 12" speakers. That's the only significant consideration here.

Thanx..I intended on using both cabs tonite on our gig, but then changed my mind and used the 15" Celestion in a closed cabinet.
(8 0hms)

It broke up pretty bad..maybe too much bass on my settings.
Using the same settings I tried the 2-12" speakers, (1 Mesa Black Shadow and 1 Celestion Silver Series 70 Watt.)

I have been using this cabinet for about 4 years and it sounds great...at my house at a lower volume the 15" sounded really good but out on stage it just didn't cut it so I sure don't want to use it as an extension.
Just another dumb idea in the pursuit of a better sound.

You play at lower volume sometimes, Jack? I did not know that!

That's funny, b0b.
Actually the other guitar player/keyboard player in our band put on a wireless and went out fron sat. nite and came back and turned his 50W Music Man amp down and appologized for all of his nasty comments....SO THERE!
