I spoke to Andy at subbox.net today regarding the 1.5 ft3 airspace dimension that is posted on the website for the SuperCrew. IMO, 1.5 is entirely too much for a 10 inch sub . In fact, very few sub specs will fall within those parameters. He said that he spoke to the manufacturer of the box, and that the 1.5 posted airspace was in fact .780 ft3. He has already made the changes on the site.

This correctly listed airspace certainly opens up a wide range of possibilities for a 10 inch sub that I didn't have before.

 

Andy is great to work with. Before I ordered my box I believe i sent him about 5 emails in a hour and recieved a reply right away. Great guy to work with.

 

I have had that very same question for the past month or two!! I have been trying to do my homework on which speaker to buy, and, assuming that 1.5 cu. ft. was correct, I was think of trying to shove a 12 in there. I'm glad somebody called and asked - Good work!
