In Reply to: RE: Anyone tried this baffle design? posted by amnesiac on June 20, 2014 at 09:08:25
that's a very old idea and it is a 360 degree reflex vent right on the driver. Ought to work like a charm. Best regards Moray James.

An idea. This may be bad. Suppose the four sides of the baffle are curved out to make a vent like a horn all around. It can also be made straight instead of curved to get a tapered vent. Perhaps somebody has tried and given up. But with the new excellent drivers, it may be worth a try.

you could make either of those ideas work but you would be made to tune by ear rather than using a design program. I expect that the real benefit this design may have is the fact that the vent acts so directly upon the cone action. Best regards Moray James.

still strange I cant see why it doesn't cancel
The mass of the air in the vent space delays the back pressure. It DOES cancel, below the tuning frequency. Same as any other ported design at low enough frequencies to use a lumped-element analysis.
