I've tried the 10" version, which I was about to buy until numerous others expressed concern over anything below 100 watts. Personally, I thought it was definitely enough power, but that's just me and I know nothing lol.You forgot to add IMO.
Ive owned a rumble. I own a Ampeg RB.
IMO the Ampeg is infinitely better than the rumble mud box..
To the OP.....the RB comes with 10, 12 and 15 in speakers... try on of those.
