Fender Rumble Club

The conventional wisdom here is that they left off the foam to help achieve a price point. This amp straddles the beginner/home player/garage band and smaller venue gigging markets. Adding foam and reinforcing rigity are desirable things for most of us, but they would also push the price point up. Right now it's probably the most popular mode of Rumble.
To help determine what the most popular models are ... a survey!

Mmmm, ... y-y-yeah? ... kinda ... I guess, maybe. The Rumble 100 combo also lacks an extension cab facility and was not designed to support a 4 ohm speaker load, like the 200 & 500 combos were.​
Yet, many of them now come with a Pre/Post switch on the XLR Out that the other combos under 800 don't have!? But, apparently, that's more a side effect of getting an alternate power supply and power amp module due to manufacturer's materials management.​

Yes, at least per discussions here in The Club, chaining two R100 combos together seems to be a fairly recent, and growing, trend (with or without any added lining)! 👍

It sounds like foam is effective at reducing the Rumble v3 boominess. I thought poly fill and poly batting were preferred. Is one better than the other, or do they work about the same (just use whatever is on hand?)

A (stock) Rumble 40 v3 I'm working on sounds boomy to me so I was going to line one side and the bottom with poly, per advice in another thread. Wondering if I should use foam instead. Interestingly, my v1 Rumble 60 isn't boomy at all.

"Ploy batting" sounds like a cricket tactic, if not a strategy!
I have no empirical evidence, but suspect they all work reasonably well, if in slightly different ways.

For me, it was what I had on hand to try.

The amp sounds pretty good as is, so I wasn't going to go out of my way (and out of pocket) to experiment.

If I felt the poly fill would made a significant difference, I'd get it.

I think it's more having some sort of absorption in the cabinet that is helping.

But whadda I know! I'm just the bass player!
 
The purpose of lining a bass cab is to control reflections of lo-mids inside the cabinet. It is not necessary to line the entire cab. Partially lining one or two sides is sufficient. All you are doing is using the foam to absorb reflections. That is what causes the "boominess".

I used to design and build bass cabs. I was one of the first to build Dave's (Greenboy) fEARful 15/6 cabs so long ago. There is no need to line the entire cab, and partially plugging the port is not a good idea as it changes the tuning of the cab, and possibly causing over excursion of the driver at higher volume.

I might add some lining to my two Rumble 100's but honestly, EQ'ing is a simpler solution. Typically the boominess is around 100Hz. I guess do whatever works for you.
 
After all these years I finally came up with and used in great condition Rumble 200 combo and I cannot be happier! This amp is all I was expecting for it.

Now I'm on the line to get my club number :laugh:

Also I want to be kind and t to thank whoever is in charge of the Fender Rumble Club Wiki Page, it's been very useful.
Congratulations and welcome!

¡Hola! @Keitor, you are now member #1835 in the Fender Rumble Club. Congratulations and welcome. Put that number in your TalkBass Signature for safe keeping.

Thanks, but you, sir, and your fellow Club members, are in charge of the Fender Rumble Club Wiki page. I'm just the administrator of it for you. Make yourself at home there and just let me know if it needs any additions or corrections. Feel free to send me a Direct message, or to discuss it here in The Club posts.

Please tell us more about yourself, such as your bass experience in general and your Rumble journey in particular. You'll fit right in here since we have all kinds. But we all love to ... ... ...

August 13, 2019: I've had my Rumble 100 for almost 5 years now. Mainly used for practice, but does a few gigs also.
Daughter borrows it occasionally as a portable PA for some of the activities she organises at the aged-care home. (And yes, she has booked my band to play there on 2 occasions!)
These current models have a great power to weight ratio for us older blokes!

After what I did to it last weekend, I figured it was high time I put my hand up and posted something about it.
I love its sound, but occasionally felt it would be nice to have a tweeter option for a bit of extra brightness like the 200 & 500 models offer.
Did my homework and settled on the Monacor img stage-line HT-30 tweeter. It's a good match from an efficiency and crossover frequency point of view, and one of only a few that would fit in the limited space in the top RH corner of the baffle. Even then I still had to make a flared hole and mount it behind the baffle for a neat fit.
The woofer rollof occurs just below 5kHz, so sticking with Monacor's recommended crossover frequency and slope (5kHz & 12dB/octave) are pretty much ideal. That made crossover design easy and did not require an LP filter on the woofer.
I took the signal from the woofer terminals so didn't need to open up the electronics section. The crossover was built on a solder-tag strip and I installed a recessed IN/OUT switch on the baffle as well.
Efficiency turned out to be a bit higher than the woofer, as you'd probably expect, so after initial testing I added a 5dB L-pad that brought it into line very nicely.

April 23, 2025: I've made a few posts here and contributed to the recent survey, but it appears I've neglected to request my Rumble Club membership number!

I apologize, surprise, that you weren't properly invited to join by posting a pic of your Rumble, back during your prior posts. Thankfully, that is no longer a requirement, but an appreciated option. @surprisetech, you are now member #1836 in the Fender Rumble Club. Please put that number in your TalkBass Signature for safe keeping. Then make yourself at home here and on your Rumble Club Wiki page, the repository of all Rumbling wisdom and knowledge.

Please tell us a bit about yourself, such as your bass experience in general and your Rumble journey in particular. We look forward to your continued participation here, where you're sure to fit right in, since we have all kinds. But we all love to ... ... ...

Changed up my speaker grill cloth again - I had the notion that a Rumble Oxblood Series might look nice.

I rather like it! I've got one cab finished, going to finish up the other one tonight (hopefully).

Sweet! I've been contemplating black but now I'm thinking this - or something brighter. Hmmm...
I have a similar foldable hand truck. What's that behind it? A hose reel?

Good eye, hose reel indeed! 😄👍

Not sure if everyone's interpretation or shade of Oxblood is exactly the same. I really like the dark/chocolate color. I got my material from Speaker Builder Supply, it was the 24" X 36" size for my Rumble 115 cabs.

Thanks for the tip. I may go with oxblood. Looks like SBS's smallest size (18x36) should handle two R100s!

That's vera nize, ray. 🤩

I wonder had you, possibly, gotten even some subliminal inspiration from the variety of grille-covers and cabinet covers included on the Fender Rumble Artwork wiki page? 🧐
