Planning on getting 2 12" Memphis M3 dual 4ohm wired to 1 ohm on a mc1.1100 amp. What box would be better fit for SQL. A sealed box built to be the biggest by the recommended specs or a smaller ported box tuned to between 35-38?

35 is high for an "SQ" box.
Sealed is the easiest. For a true SQ build, just build to recommended specs, and start messing with it. Add polyfill, take out polyfill, etc.

So you think I shoud build the biggest recommended sealed box? Polyfill makes the sub think the box is bigger right?

Go with a ported box, just tune a little lower than 35hz, maybe around 32hz.

Standard ported boxes tend to have a kind of peaky response for SQ, I might try something more like Bi-chamber.

Sealed is always a good choice for SQ.

Or you can use EQ to tune out the peaks ;)

I ran a DD9515 tuned to 42Hz and with some EQ work it was VERY musical...
