After viewing TC's website, here are the ideal box req for a ported 10" lms.
3" port 21" long.
That puts me at 21hz, and a port much longer than I can really use. SO, I'm thinking something like 3" port tuned to 27hz, witch will put me at 12". That's something I can use. You guys think that would work better? If I make the box sub & port up with it being 15" tall, 12" deep, how wide would I have to be to get my 1.8 ft^3?
