Hi Matt. I think you’ll be happy with your purchase. I have the same cab setup as you but with a Rumble 500 head. You’ll be ready to play pretty much any venue with this setup. Enjoy!After all the feedback I received on here, I decided to go with the Rumble cab series for my Bassman 500. I ordered just one 410 to gauge in person before ordering a second to run in parallel. I had been using a Peavey Headliner beforehand. I have to say, the Rumble is much clearer and punchier than the Peavey. It does have a little less low end, but not in a bad way. I decided to order a Rumble 115 to go with the 410 instead of running two 410s.
Another thing to note: When I first got my Bassman head, I dialed in the settings with the cab and found it to be drastically different than what I heard through the DI. The Rumble cab is MUCH closer to the Post EQ DI sound of the Bassman series.

Thank you kindly, G-Dog.I'm not a professional photographer, and I don't play one on TV; in fact I'm colorblind; so maybe this isn't really a compliment but, I absolutely love your photo, vanny!
In my opinion cab makers should always put sound proofing in. It helps tremendously.
Your Rumbles are already factory lined with poly acoustic treatment. Shine a flashlight through one of the ports and look through the other and you will see. You can spend more and replace it with acoustically engineered foam if you like, but the factory treatment is effective.Who has added batting or foam to a rumble cab and what was your result or opinion?
Thinking about doing it to my 210 cabinet and the stage 800 to see if it tightens up the bottom end a little.
My r100c had no sound dampening in it (not that price range xD) and i used ~5cm thick foam insulation. At least i "think" it's better, but should have been measure before/after. Had no time for it.Who has added batting or foam to a rumble cab and what was your result or opinion?

The Rumble 200 combo up and all cabinets are all factory lined. So is the Studio 40. I don't know about the new Rumble LT25. Rumble combos: 100; 40, 25, and 15 are all unlined.My r100c had no sound dampening in it

That was actually a V2 Rumble 75. Upgrading A Fender Rumble 75 ComboI'm confused, I'm certain I read several posts by you recommending on another thread what kind of material to use in a studio 40. Didn't you add foam in a cabinet or an I mistaken? I am at a brief stop and can't do a search.

@AstroSonic (along with several others) upgraded a Rumble 40 long before the Studio 40 debuted. @eric_B made many serious mods to his V3 Rumble 100.

I thought it was more like an inch, but at any rate it is effective in breaking up standing sound waves in the cabinet and damping rebounding sound waves. Too much acoustic damping will result in a 'dead box', and sound that way. Not a good thing. The right amount allows for a lively and responsive cabinet that adds to the musicality of the amplified bass. A bare unlined cabinet is typically unfocused and the hard naked surfaces imparts an unmusical 'boxy' countenance.there's batting inside, not very thick guessing about 1/2".
