Going to put a pair of Tempest X2-15" in sealed boxes. Manufacturer indicates that a larger sealed box is a better sealed box...
It seems to make sense for me, to put them in ~13 cu. ft. boxes, for various logistical reasons (not sound quality related). Manufacturer does not say what happens beyond 8 cu. ft.
Is there any detrimental effect due to putting a sub in a larger sealed box?
Thank you.

Hi,
A pair in a 13cuft box seems fair enough for a 9 cuft Vas driver.
Qbox will be about 0.65, a very well stuffed box about 0.6.
-3dB around 33 Hz.

Hi,
You will gain next to nothing by going over 9 cuft per driver.
But then again if 13 cuft is convenient, there is nothing lost.

You may gain sloppy bass with a large cabinet.
The sealed box acts like a spring pulling back on the cone (or pushing on the in-swing).
Without that resistive pressure both directions you are relying more on the driver's suspension and can run into damaging the suspension system on the driver.

I believe this is incorrect. Drivers in an oversized sealed enclosure are considered over damped. The "air spring" inside a sealed enclosure can help to control excursion, but does prevent it from being "sloppy".
