Odd Bass application need help

I have a little situation and I am wondering if I can fix it with some BASS.

My wife rides horses and their arena is a fabric building. See the photo. The arena is 150 feet long and 30 tall. Snow build us on it and slides down the sides at unexpected times. The horses spook at this noise and people have been injured. It appears the horses running in the area set off the snow. If you have not experienced it a horse running in an enclosed space like this can be really impressive and the sound is deep and intense. I am thinking if I can get a 60 Hz wedding bump going in there I can get the snow to fall.

Another strategy is to get industrial vibrators that will vibrate the structure. They will have to be up high and are quite expensive.

I need to create a woofer that will be able to excite this building. It can not be extremely large, large and flat may be OK. If I need more than one that would be OK. My limited experience says what I feel at weddings will do the trick.

Is this doable? Is the arena too big? Should I build something or buy a PA sub system?

Do you already have a subwoofer in your house? If so, drag it over there and test it out. If it works, look into building one for the site that meets your size requirements.

Have you thought about mounting some butt kickers on the framing? They won't take up any space.

Yea I would try that but I have a Danly DTS10, not exactly a toss in the trunk kinda thing.

I have to agree with dTorC4 perhaps some tactile transducers.

What you're experiencing is that the activity in the building generates heat. Heat rises, eventually melting enough snow to allow it to slide off.

Run one of these for an hour before the event.

How about some good sized shop fans blowing against the fabric. The vibration(flapping)from the air should prevent a lot of the snow from settling on the fabric...bonus...in summer will help cool the place.

Edit: Briefly looked at a site that specializes in air supported dome fabric buildings, they suggested dragging a fairly heavy rope over the structure to dislodge the snow. With a building your size...you'd have to use a lighter rope with a weight on one end to throw over then use it to pull the heavier rope over. Two guys should make quick work of it.

If you do go with the AVS approved audio option, maybe a horn-loaded sub that can project/direct the sound waves would be a good idea. Run some fr sweeps and see what gets the structure resonating/excited.

Good idea.

100X more efficient way of getting vibrational energy into the fabric.

Another idea:

Is there a high school nearby? Get some linebackers to run into the fabric wall instead of pushing those metal sled things.

Or soccer players to practice their goal shots.
