    I believe that the 4628B and the 4612OK systems used 3khz as a crossover with 12db/octave slopes. It was fine for high spl commercial systems, so I can't see why that crossover point would be a...

    Thanks everyone, this is some really god information. It also makes a lot of sense since I bought this from a mill-work company. They probably use it for making doors.

    Thanks, I appreciate the responses. Anyway, I'm almost finished the enclosures, and they look nice and solid. This material seems about the same as regular MDF to work with. By the way it is the 1...

    Double Refined MDF

    I started a new speaker project last week, and I bought my MDF from a mill-work company instead of Home Depot. As I began to cut the parts out, I realized that this MDF was noticeably harder and...

    Baffle layout question

    If it can be physically accomplished, is there any reason why you wouldn't want all the drivers on a baffle close enough to almost touch each other? Is there any minimum recommend spacing?

    According to my box program, a Qt of .80 is a .497 cu ft (net) Vb, and .58 is a 1.101 cu ft (net) Vb. The program suggests a Qt of .648 with a .835 cu ft (net) Vb. Are these enclosures too small? The...
