We've gone through this a number of times, and it can be confusing and often disappointing. Forget brands and lets just look at watts. At 8 ohms through identical speaker cabinets 140 watts (Rumble 200 @8ohms) vs 350 watts (Rumble 500 @8ohms). Electronic rule of thumb: To increase the SPL +1dB you must double the power. OK, fine. 280 watts is a piece of cake so +1dB. To get another dB you have double again to 560 watts. A lot of people can't even perceive a 1dB difference. That's with any amp. To double your SPL you need 10 times the power. In this example you would need 1,400 watts.Question ...
i used to have a rumble 200 v3 head , later on i sold and trade different things and now im on the hunt for another amp ... is the 500 rumble head that much louder than the 500 or for those u have both or used both u can’t really find that much of a difference ??? i know one is 200 & the other one is 500 but u know with the ear , is it that much ??? i used to have a tc bh250 & a hartke tx300 after owning the rumble so im looking to get something around that price point and sound wise ... thanks

What you are going to get with 350/500 watts over 140/200 is more headroom. If you're a motor head think of headroom like torque. You can feel it when you play. The additional wattage is going to give you better low Hz reproduction. Lows are watt hungry, and feeding time is always fun.
"You can check out any time you like, but you can never leave."definitely the best explanation & exactly what i need it ... thanks , looks like i will be back on the club pretty soon !!!
Welcome Rumbler #1011! Rumbles are sleepers, for sure. I think Rumbles are getting more respect than they one did. Rumble On!Would love to take a number! I have had my Rumble 60 for six years now and love it dearly. It is my small gigging/rehearsal amp too. These amps are HIGHLY underrated in every sense of the term. Sleepers for sure.
You can download a db meter for your phone.Back to noticeable wattage differences. I love my Rumble Studio 40. It really doesn't sound low wattage at normal personal practice volume. In one dB chart normal conversation is listed at 65dB and a vacuum cleaner at 80dB. I don't have a dB meter, so I'd guess I'm playing about 75dB.
If I plug into my Rumble 200 combo at about the same volume (me guessing), I can really tell the difference in wattage just by the feel and also by the additional low end and quality of note reproduction. The Eminence 15" makes a big difference as does the larger cabinet and port tuning so it's not just wattage alone.

Nice autographed Tea Party poster. They're locals, well JB still lives here. Cheers!I’m yet to gig with the extension cab but loving the fullness it provides when paired with the combo at home.

I do not have a phone. I am an impoverished disabled veteran, and am too poor to own a phone or pay for phone service.You can download a db meter for your phone.
