is this enough bracing?

[taintedplay 10+ year member]

ok subs will be 4 15inch re se's off of a aq3500d

1. one threaded rod down the middle, is that enough?

2. ill have a flushmount baffle(as shown) but is two sheets plus the beauty panel ontop needed?

3. also, i only have room to mount the aq on the box, if i have that side double thick mdf plus rubber grommits, is that enough to stop vibration/flexing?

or this. the lighter gray parts would be like 1x4's covering all the edges and down the middle

looks good, all-thread will hold that ish tight, dont worry

would use threaded rod between each sub top to bottom too...

SE's are light woofers, i wouldn't worry about all that extra bracing....

Its not the amount the subs weighs that determines bracing!The MM of 4 15's at 45hz is alot and at resonance the box can flex tremendcily.The bracing is to stop this not support the weight of the subs.

id rather be safe than sorry, and since my amp is going to be on the box i really want to be safe. heres what i think ill do. 1x1 board run around like i showed, does it matter what type of wood?

then allthread down the middle, and between each sub. then on the wall with the amps, have it double layered

That should be suffecient.
