Precarious situation?

Here is a solution;

Obviously you would need it quite a bit larger. Put feet on it where they need to be to make good contact with the bottom cab. I use mine so I have a flat surface for a laptop, interface, phone, etc.

I used Plasti-dip in a spray can for a bit of extra grip and vibration deterrent.

Love it, what a great idea. Simple, extra cheap and very useful. As a DIY guy myself, I can only applaud you. There is nothing greater than DIY solutions.

A good solution.

I take the same approach when stacking heavy amps and cabinets. Specially ones in storage. The advantage of this approach is that it spreads the weight evenly over the top of the lower cabinet. Even when cabinets can be stacked without overhang, it avoids indentation in the cabinet wood from feet. This can happen with enough weight in a stack.

I find that particle board stands up well. For larger overhangs I prefer 3/4” plywood.

I’ve done exactly this but added holes for the feet.

I really do appreciate all the suggestions and input being offered... many thanks!

For those of you that have suggested a solution to my initial post (Mesa on top), that's a moot point now since I have decided to place the Rumble a top the Mesa. I found that it sits on their solidly.

My concern now is possibly offering too much power to one (or both) of the cabs and potentially damaging them. I'm pretty upset about this because I never thought I would have any worries regarding this when I purchased the Mesa.

My Rumble 500 would have the wattage split between the cabs, so I thought I would be ok. Some have pointed out that this is not necessarily the case. So now I am at a crossroads as to how to approach this situation.

I also have a Rumble 410 cab and could pair that with the Subway but that would defeat the main purpose why I purchased the Mesa... easy portability.

My Rumble 410 is for sale now on FB Marketplace.

What to do?!!!
 
Use the 115 with the Mesa and don't sweat it; keep an ear out for signs of either cab being overdriven, but the Rumble would be the one to be concerned about. There is no particular 'red line', per se, but you know you can run it up to at least 10 o'clock, it sounds to me like. Obviously having a second Mesa cab would be the optimum solution.

Moving the feet on the Rumble is the obvious answer if you're at all concerned about the precarious nature of perching it on the smaller Mesa. Don't worry about the holes...no one will ever know but you. It's a dang ol' speaker cab, not a precious Steinway.
 
Ok... now I'm feeling foolish and disenchanted with my situation. I really don't understand speaker impedance and how an amp delegates power to the cabs, so now I'm afraid to use my Mesa cab!

I'm thinking I should just put the cover on it and continue using my Rumble 410 with my Rumble 115 until I can afford another Mesa cab. I also use a Tech 21 VT Bass Deluxe preamp/DI with this rig.

I also use a Broughton HPF in my signal chain... will this help protect the speakers from overload?
Assuming both cabinets are 8 ohms (I know for certain the Subway is), you will be fine. That's a plenty good power match for both cabinets.

Thank you agedhorse!!! Yes, the Rumble 115 is rated at 8 ohms (300 watts).

You have just made my day!

You are a wealth of knowledge and information for all here on TB and your reputation is well respected.

I really appreciate you chiming in on this thread. Again, THANK YOU!!?
 
Got a new Mesa Subway 115 yesterday. I would like to pair it with my Rumble 115 cab.

I have the Mesa sitting on top of the Rumble. The feet on the Mesa are almost completely making contact with the Rumble cab. Maybe a millimeter or is/are peeking over the edge. I played this setup at Sweetwater before I left with it. I had it at a pretty loud level for a few minutes and I didn't notice any shifting.

I placed the Rumble on top of the Mesa and the feet of the Rumble hand over the sides of the Meds... But not by much at all. I was just thinking that the Mesa being on top (with it's feet contacting the Rumble) would be more secure than the Rumble "straddling" the Mesa with the feet not making contact at all.

I'd like your guys thoughts/suggestions.

Many thanks!

Add or move rubber feet to an area where it makes better contact.

Just use a plywood spacer the thickness of the feet so that the bottom of the top cabinet rests on the top of the plywood and the top of the bottom cabinet rests on the plywood.

Pro audio guys deal with this sort of thing all the time, a workbox usually has a drawer full of various audio spacer devices (painted black)
But then that affects the tone, if the plywood isn't swamp ash or unobtainium!

You are fine. Enjoy it.
The Subway can take more but your amp is not giving out a lot to worry much about your Rumble.

Just remember you are only as strong as your weakest cab whenever mixing cabs (whether speaker sizes match or not) and all is good.

Great idea! However, after reading all of the suggestions and advice, I went with putting the rumble on top of the Mesa. since it is an inferior amp, I probably have to pay attention to how it's handling the load. The Rumble isn't going anywhere, I am sure. I'm just going to have to deal with this situation until I can afford another Mesa cab. And finally a Subway head.
What gig situation are you dealing with that requires you to push your cabs to the brink? I know you got an XLR out on that Rumble 500.

Or, just a slab of wood, with feet attached to the bottom in the right place, with SW on top. Sometimes those holes are a pita to cut.

Simulate gig conditions.

Set whatever cab you like on top of the other, turn up to gig volume and play. If you're on a wood floor, jump around a little.

If the cab falls off, reverse the order. Test again.

But I don't think the mesa is going anywhere if it were to stay on top.
 
Our drummer is crazy loud and the guitar player runs a 100 watt Marshall through a 412. Since the drummer is so damn loud, our singer has to bring the PA up a few notches, so... I think you get the point.
This is where having a tall stack can actually reduce the overall volume.

If you put the acid on the drummer to use dynamics and a lighter touch overall the first thing he will say is Jimmy P over there plays so loud I can hear myself.

Get guitar player to put his cab on a stand and point it squarely at himself.

You won't need to plug your bottom cab in at that rate.

Agedhorse knows a lot about Rumble amps. I still don't know that you could really crank on the stack and not fart out the Rumble cab.
