Enclosure suggestion for max output

[los33 10+ year member]

I currently just purchased a DB Drive WDX 12 5k.

The current box i put this in was originally for a older orion hcca 12d and the measurements are:

Box size: 34" wide x 15.5" deep x 14" high

2.5^3 of airspace tuned to 33 hz

Now this sub is literally over powering the box with only 1500 watts which the suggested ported size is:

Ported : 3.4 Cu. Ft / 96.27L

I plan to purchase a second one, but when i create the new box is it better to keep all the inside rounded to allow air to flow?

Rounding the port wall and outside of the port will help with air flow.

What exactly does "overpowering the box" mean?

Rounding anything inside the box will help air flow, but you may not notice a difference if you have enough port area anyway.

It would be helpful to know what you mean by "overpowering the box".

I assume you mean there is vent noise and if that's the case, you don't have enough port area. As for rounding internal surfaces, none of that will make any appreciable difference other than the port itself being flared.

Haha have you ever seen mdf wood expand by very little?

The pressure of the air being pushed makes the wood expand from the top of the box in a very small bulgeing look.

The box has never been wet or damaged also.

And yes there is some port noise.

So pretty much the sub is destroying the box, eventually tearing it apart... You need a new enclosure with bracing and double baffle with proper port area.
