What enclosure volume and tuning would you recommend for an orion hcca 10.4. The website says 1.2 tuned at 38 hz, but that sounds a little small to me. I was just wondering what you're running it at, or what your recommendations are. I will be running two, and I would like it to be tuned at about 32 hz, but i want to get the most out of the sub. I don't want too small of a box because I really want it to hit the lows, and I definitely have enough room for a big box. Thanks.
