Smaller opening than driver?
« on: 24 Aug 2020, 03:09 pm »
General question...

What happens if a driver, say a woofer crossed at 200Hz, has an opening in the baffle that is smaller than the driver?
The driver would be set back about 6" from the opening, with a cabinet construction that "funnels" to the opening.

So, say you were dealing with a 12" driver, but the opening in the front face of the cabinet was 6" h x 12" w?

What about if the total opening size remained the same, but was a different shape.  So instead of 12"x12", it was 6"x24"?

Lastly, what happens if only the front of the driver has this reshaping, but the rear is kept fully open?

Thanks.
