Quick Baffle Question

Hara · 22nd December 2005, 07:41 AM

Lets say you have a lot of space, and you have a small boxed speaker that needs baffle step correction. Is attaching a baffle extension to make the baffle really large a possible, although not necessarily practical, solution? Sort of a open baffle + boxed speaker design?

I'm concerned about a particular project of mine, I had some construction problems and have to make the baffle slightly larger although the internal dimensions remain the same.

I'm curious of the effects of making the baffle larger in the dimensions of width and height while internal enclosure dimensions remain the same.

Hi,

yes, a large baffle will lower the baffle step in frequency,
until with a very large baffle its academic due to the box
bass roll off or the interactions of bass with room nodes.

Still usually much better to get rid of the box, unless the
driver has a low Q requiring a box smalller than its Vas.
