what is the recommended port area for ssd's? box will be around 5 cubes tuned to around 33hz. 1 port 5" wide 20.75" long would give me 75 square inches. and 4.5" wide 17.25" long is 67.5. is one better that the other? and y?

also just curious how much does a 12" SSD weigh and a 12" Q?

We normally recommend 12-16 sqin of port per cuft of enclosure. This is a general rule of thumb and is not set in stone. Obviously higher power higher excursion applications need more than a low power low excursion setup (which can use even less than what we recommend with little noise or compression).

Between the two there is little difference. You wouldnt notice it as much as you might in radiusing the edges inside and out on the ports. Either one would do fine.

Thanks,

Scott
