I'd recommend a Weber 15F150 or 15A150 or some variation there of.MaxWedge said:Yes it's a fifteen inch RS. That said it pretty much makes the cabinet useless for a 12 inch classic sounding speaker, you know something that will release the warm tones I know that are in this amp. 15-22 watts, a 30 watt speaker should do the trick. Remember this is basically for my living room.
