Very happy with Rumble 100!

So I'm a drummer.

For those still reading, thanks! I do play a lot of bass these days and get way more bass gigs. My "main" bass rig has been an Ampeg BA115 (100w, 15") combo amp I've owned probably 15 years or so. Weighs a ton but the bass hits you in the chest. Now that I am playing out 4-6X/month, and being an older dude, schlepping that amp is a real PITA.

So I recently picked up a Rumble 100 (100w, 12") for a screaming deal used at a somewhat local GC ($129, and $140 out the door!). It looks and plays like new. My concern is whether it had enough low end to handle blues/rock gigs. I know at home, I cannot turn up the Ampeg to the proverbial "11" as it's just too loud. However, I can turn up the R100 all the way. This made me very nervous about whether it was enough.

I am in a band that is a coffee house/Americana/pop/light rock band and we recently gigged a big room (coffee shop) and I used the R100. The staged was cramped so I had to stand in front of the amp. It was moving a LOT of air to the point that after the first song, I had to move out of the way. But at 5, it was more than enough for that gig.

Last night was the real test. Full rock band with 2 electric guitars, bass, drums and vocals in more of a bar scenario. Well, I am very happy to report that the little R100 pumped out some serious bass tones. I got compliments by the drummer, both guitars and our singer. I had the volume turned to about 2:00 (7?) and ran my bass (a 1966 P bass tribute - a hot rodded Squier, original 63 PU's, upgraded pots/wires, and mid-heavy relic by yours truly) directly into it. No effects, preamp or pedals. All I can say is heck yes!!!

I am debating if I should upgrade the woofer. I recently did this on a R15 I have, finding an 8" subwoofer on CList for $10! I swapped out the woofers and I can now turn that little practice amp up to "11" without popping or maxing out the sound and get a low bass tone. A real game changer.

I would like this R100 to be my main gigging amp for now. If business picks up, I will consider a separate amp and cab. But I had to walk about 1/2 block and doing it with the bass over my shoulder and carrying the amp was nothing since it's so light. Definitely stoked, though, since I read that the R200 should be the minimum amp for a gig............

If anyone has suggestions for a 12" replacement speaker, please let me know. And of course, part of me wants to cut out the 12" and make a hole for a 15"!

I love mine too. My gig these days is at church where I play through the board, so my Rumble stays in the bedroom for home rehearsals. I bought a cover for it as I was afraid the wife's cat would use the cabinet as a scratching post. When I lift the cover, my dogs tuck their tails and slink away. May be a message there somewhere, I don't know.....
 
Does your combo have the Pre/Post DI switch?

If so, it almost surely has a 4 Ohm driver.

The driver that the person above mentioned is an 8 Ohm driver that works in older versions of the combo.

A 15" driver stuffed into that small of an enclosure will not work as well as the stock driver.

I bought a used Celestion BN12-300S (4), 4 Ohm driver in mine and it sounds great, but it is not a cheap driver at all.

It works great though!
 
I agree with ops delight. My old band boys and me get together once a year to jam.. we are all separated by at least 100 miles and we’re all over 60 now so it’s seldom. Drummer has a R200 that I use. It’s wonderful… I dial in some drive and get my P Flats just singing.

Then I visited my dad 1000 miles away and jammed with his band. Really old guys, 75-82. They had a tiny rumble 8”. Two guitars and drums and me. That little thing was fantastic in the home bar/jam room. I really couldn’t believe the tone I got out of it.

I don’t own one but I’m a fan of the tone I got out of them. Absolutely perfect beginner amps, or go-to amps for weight and performance.

If you like the Rumble 100 and it meets your current needs, definitely do not change the speaker. Rock it as-is.

I have a Rumble 100. It is all I need.

I replaced the driver of my Ampeg BA 110 with a Celestion CF1025BMB and OMG !

That brought my little combo to another level in terms of power handling, bass depth and sweet tone. Not cheap but I would never go back and this is now my go to combo for almost every thing I do now, except very loud shows.

If you can find its equivalent in a 12" or you’re willing to fit this 10" driver, go for it, you won’t regret :


 
I am debating if I should upgrade the woofer.
btw, it isn't a woofer (just because it's 12")(haven't heard that word in years not since radio shack tested tubes...) it's a single full range eminence designed for that amp and of all the amps out there I would be more reluctant replacing a rumble speaker than others, just because of how it was designed to work in that box and be light weight.
 
This thread has some great information about modifications to the R100 and the end results: NAD - Fender Rumble V3 100

Modifications in that thread include speaker changes, port changes (including blocking them), internal bracing, and adding more poly-fil lining, all with each person's perceptions about the resulting tone changes.

It's a good read if you're contemplating making changes to your R100.
 
I'm in the crowd that recommends, "if you like the sound/tone as is, don't be changing drivers and it's cabinet's tuning to try to make it into something it was not designed to be."
Modern bass cabinets are designed/tuned around the driver that was chosen to be used in that system.

If your happy with the sound but just need to be louder and with a slightly fuller low-end buy another matching R100. Stack them as a vertical 2x12 and daisy chain the two together using the top amps pre-amp as the master and the bottom amp as a powered 112 cabinet.

OP, take a look at your settings in your initial post. The R100 is already scooped to push the bass and treble. "Flat" on the amp is 10-2-2-10 on the EQ. You have both Bass and Treble up and also pushing the drive. Even though you are well under the limits of the amp, in terms of what it can handle, perhaps you would be better served with a more substantial upgrade? Even the R200 might not give you what you want. I suggest you think about going to a 2x10 with more overhead in the amp, like the R500. It's not much heavier, but would give you more tonal options, and lots more power to draw from.
