Air volume occupied by a TD15M?

    Anybody who knows how much air volume is occupied in the cabinet by a TD15M?
    I know it’s not a very critical parameter but since I’ll be running the numbers for a complex shape anyways it would feel incomplete not to include it.

    Probably around .1 cuft.

    B&C 15TBX100 is listed as 0.19ft^3, are they twice as big?

    I would guess .1cf. John has stated the correct volume here before, but I can’t find it from a quick search.

    With a 3/4″ thick baffle, a 18″ shold occupy about 0,25 ft³ / 7 L, a 15″ about 0,17 ft³/ 4,8 L and a 12″ about 0,09 ft³ / 2,5 L.

    Thanks, it seams we’re getting things narrowed down now. 🙂

    I would like to share my finished results.
    In the end I decided to go a very unorthodox route and in many regards do the opposite to the common rules of thumb.
    I went with a tiny closed cabinet, ca.50-55L and active compensation with a DSP. A fraction of a cubic foot became irrelevant and the speakers are easy to hide in the living room.
    The point I think is that crossovers, DSP and stuffing will matter more than the physical space the driver occupy and both stuffing and crossovers are crazy hard to model.
    I’ve heard people who are used to TAD speakers say they would kill for my bass, IMHO that proves that a small fudge factor isn’t detrimental to the end result.
