In my younger days, I bought the cheapest box I could find for my car subs. As it turns out, having a box with the appropriate air volume makes a big difference in sound quality. As such, I picked up this box with it's 1.25 cubic foot volume to match with my old 12 infinity sub that needed a 1.25 cubic foot volume. I stapled in some quilting material to serve as the dampening material, per the sub's manual, and put it all back in my car. My sub sounds much better now and has much more even response down to the low 30Hz range.If you need a 1.25 cubic foot volume sealed sub box for your 12 sub, this is a great option.
