2 Infinity Kappa Perfect 10VQ Sealed Volume
 

So I have 2 Infinity Kappa Perfect 10VQ SVCs coming so I'm starting to design my sealed box now.

Infinity's link to their online manual is broken, so I can't get their recommendations. I've found online the range of 0.3 to 1.0, but that's one hell of a range.

What volume would you guys recommend and any polyfill in there?

I'm going to be giving them 300W RMS each, and am going for pure SQ, nice tight and fast.

Thanks.
