Topic: Speaker resistance for a solidstate amp? |

I've got a little Fender Frontman 25 for a practice amp and it has a 10" cheap speaker in it marked 8 ohms. I found a 12" speaker from a Blues Junior and have an extension cabinet for it. It is also 8 ohms. So I know I could run the 12" 8 ohm speaker instead of the 8 ohm 10" speaker. But, is there any way to use them both? I know enough about resistance to know that if I wire two 8 ohm resistances in series that would be 16 ohms resistance, and if I wire two 8 ohm resistances in parallel I'll have 4 ohms resistance. What effect would either 4 or 16 ohms resistance load on the amplifier output be and would either one cause damage to a solid state amp? Thanks, Larry Robertson, Denver

Running the amp at 4ohms could hurt it... although I didn't find a spec for output impedance for the amp online. Running at 16 is safe, most likely... but the output power will be reduced at 16ohms. I don't think you'll notice much more output when two speakers are connected, and if they're out of phase you'll notice less output. I'd try the 12" alone first.

Hey Thanks Stephen. I'm gonna try the 12" alone first as you suggest. I'm hoping it'll be a little bit softer sound, not really looking for more volume. The 10" has 4 connectors on it and I thought maybe I would wire the jack for the extension 12" in parallel off of those connectors. I think I'll just disconnect the 10" and wire up a jack on the Frontman to plug in the 12". Thanks for your thoughts. Larry
