I have a Peavey tube combo amplifier that has one stock 16 ohm speaker that came with it. I was thinking of replacing it with a Celestion speaker rated at 8 ohms, which I took out of a 75 watt solid state line 6 spider 3 combo amp. Both are 12 inches. Is this possible without any resulting compromises? If there are, what are they?
Amplifier: Peavey Valveking 112 Combo, has a stock 16 ohm speaker, wattage unknown. Manufacturer says it is 4, 8, or 16 ohms as stated here: http://www.guitarcenter.com/Peavey-ValveKing-112-Combo-Amp-104003397-i1145634.gc – what does this mean?
Speaker: Celestion G12P80 rated at 8 ohm (taken out from a 75 watt solid state amp)

it should work, but you will have to change a tap on the audio output transformer. running the speaker on the wrong tap will greatly degrade performance. The damping ratio of the amp will be very poor when putting the 8 ohm speaker on the 16 ohm setting. Also the maximum power of the amp will be similarly reduced. find the directions on how to set up the external speaker jack for 8 ohms, that should be the same method for changing the internal speaker.
yes.
75 watt speakers are well within spec for a 50 watt audio amp.
audio amps are, unless the manual says different, 4 to 16 ohm.
the speaker’s resistance is actually impedence and is dependant on frequency.
