Does using a
guitar combo with it's stock 12" speaker disconnected and the speaker out instead
hooked up to a bass cab?
In that case here is my 160W (@ 4Ohm)
Peavey Solo Special 112 guitar combo, modded with a speaker output jack socket, used with the 12" stock build in unit disconnected and instead hooked up to a 400W 4Ohm
SWR Triad I bass cab, equipped with 1x15" + 1x10" speaker units + high frequency tweeter horn, the 15" speaker unit receiving the full signal, while an internal crossover filter sees to that the 10" unit only receives the part of the signal that is between 100Hz and 5kHz, and that the high frequency tweeter horn receives everything above 5kHz of the signal, the amount of signal send to the tweeter horn being adjustable via a build in tweeter attenuator :
