It’s a small room so it’s probably being overloaded. 

But are you sending too much signal to your subs and they are being driven too hard?

Not sure until I isolate them but there is some serious floor shaking and massive vibrations in good scenes at moderate volumes so I think it’s likely more than that.

I love the creativity.  Would it however “bounce” the monitors on top of the subs?

The speakers would possibly sway a bit, but hey, you asked for the best priced option .

Don’t overcomplicate this.  Burn yourself a CD with tones that range from 20 Hz to 200 Hz. Walk through the tones and listen for stuff in your room that rattles: picture frames, cabinet doors, Knick-knacks, etc. Yes, 1 Hz increments make a difference. You’ll be surprised what you find.

I actually used this to find out my ceiling can lights and even my Stewart Filmscreen were rattling/buzzing between 40 and 50 Hz.  The sweeps start at around 2:25 (fast, then slow):

Great video! I'm shocked by how few people actually do this.

Have not used these. I just remember someone who said yoga blocks worked well with their subs.
Sorry, that is all I got.

The price is right though, with a variety of dimensions, densities, and materials.
