Q1 Meta Foam Plugs get blown out by bass
I have a 4.2 system with 4x Q1 Metas in a workshop crossed over at 80hz with 2x SVS Micro 3000s Revo subs. I put the foam plugs into to fully seal the speakers and smooth the crossover to the subs. It's a big 24x36 space so I am driving them loudly enough to fill the room.
BUT the damn plugs won't stay in. The woofer is blowing them out and im finding them on the floor the next day. I am pushing them in as far as possible while still having a reliable chance of pulling them back out (don't want to lose them inside the port or enclosure)
I could 3d print something but im assuming foam is the right solution for absorbing resonance. Should I put them in loosely and cap them with a 3d printed cap? or would the cap introduce resonance by acting as a hard reflective surface? Is there some other recommended solution here?
EDIT:
To be fair, I've been hitting that KEXP recording of Angine De Poitrine pretty hard over the past week. on reflection, that can't be helping.
