best way to brace

Which is the best way to brace?

bracings inbetween the baffle and back piece?

or

bracings between the top and bottom piece?

or

BOTH!?

You want the braces in the middle of unsupported sections...

So yes, having both vertical and horizontal bracing would be ideal...

make shure the bracing runs in line with the airflow

in the enclosure..you do not want any turbulance inside

the enclosure....

the secret to good bass is good airflow..the smoother

the air can move,the smoother the bass

bracing that resembles any sort of a wall or screen door

will cost output and change the woofers cupping of the air

and will result in depleated performance

hazardous0388 is totally right. Keep your bracing via the air flow, tie in the walls, and 45 the corners. The better the flow, the better the bass.

Hope this has helped you.

Window braces also work well for large enclosures...

there is always the option of doubling up on the pannels....

this enclosure does not need bracing

an enclosure with doubled pannels has a much better sound

than an enclosure with out

cutting a side wall in half (ex. threaded rod in the middle) is better than double layering. that is simple high school physics.

double layering produces a deader sound increasing SQ...

even with a threaded rod the MDF still vibarates

I used to use threaded rods about 2,000 boxes ago

but propper bracing with MDF stiffins the walls better

than a rod

place a quarter on the top of an enclosure and pound the subs...

if the quarter bounces or vibarates around on the box there is

room for improvement

if any pannel is vibarating energy is being wasted

exciting any air anywhere other than the port and woofer

cone will have an effect on out put and sound quality

What method and adhesive do you use to get the two panels together and not have them rattle?

I use carpenter's glue and screws....

I have never had an enclosure rattle in the 22 years I'v been building them

I can't argue that doubling panels will reduce rattling, but most would prefer to not have a very very heavy box.

Thanks THUMPPER, I want to try that on my next box... at least on the front panel where the subs will mount.

Threaded rod is much much better than using wood braces like done in many of those boxes.

I'm not trying to start a pissing contest but

NO it's not..

rod bracing does nothing to stop other parts of the pannel

from vibarating..I used metal rod bracing in the past and

a propper wood braced box is much stiffer all around
