I totally agree about the enclosure makes the boom !! What do u mean by the cookbook ? I was thinking of making an enclosure box-like on the outside to resemble a carseat, then a cylinder on the inside to funnel the air, respecting of course the ft3 required to make it boom. Ever heard of anyone doing this ? I know it would be big, but the ft3 would be reflected in the cylinder, not the box. The box would only be a shell Input ??
Huh...? the cookbook = Loudspeaker design cookbook, by vance dickerson As far as the box goes, the outer box would be for show/wasting space, a cylinder/tube design is nothing new, they are just as effective, infact bazooka has made a name for themselves by providing bazooka tubes for years and years.
