Default BK Monolith build

Hi fellas - I just bought a BK sub woofer plate from the monolith plus 500w.

I have ordered the eminence driver and the MDF.

The dimensions of the sub are 540h x 420w x 560d

My question - the driver is set in the 420x560 dimension, but given my room set up I would much rather set it in the 560x540 dimension and have less sub projecting into the room.

So have it FF in the side rather than DF in the bass.

Is performance about the volume of the enclosure and port length, or are the dimensions key as well?

Many thanks for your thoughts on the matter.

Ps - I'm mainly aiming to use it as a beef up for my Full Range drivers, so question number 2-would having this as a sealed system alter it badly, other than the loss of volume?

Thanks again

You can put the driver on the front changing the width and depth.

The dimensions matter little, about 100L internal tuned to 22Hz.

Sealed would be about 40/50L stuffed and would work fine,
but not the same in terms of the extreme bass extension.

rgds, sreten.
