Best sealed box volume for RSD12?

[HiFi]

I've seen different recommendations..

The PG manual says .78ft^3 (SPL) and 1.2ft^3 (SQ).

In a CA&E test report, the author says..

I called Errin Keeling at Phoenix Gold, who turns out to be the guy who did the final in-car listening and enclosure recommendations. So, Keeling would be the correct guy to ask questions to when it comes to this subwoofer. I asked him to give his recommendations on the proper size and type of enclosure for the very best in sound quality when using the RSd12. He recommended a 1.8ft3 sealed enclosure. He stressed that the RSd12 would work in any sealed enclosure that measured from 1.2ft3 to 2.0ft3.

So, with 800WRMS of power and for best SQ, what box size should I go with?

With the original RSDs, the bigger the better. After 1.5 or so, the difference is less noticeable.

Fun fact: Errin is VW337 on the phorum.
