Home Speaker Asylum

General speaker questions for audio and home theater.

RE: FAQ

A closed-box system is something different.

If you put a driver in a smallish box with significant air spring resistance and/or energy storage of some sort then power requirements will go up. (Think Carver Sunfire subwoofer from years ago for a well know example.) :)

However, an open-baffle (or an infinite baffle) driver requires X amount of power to be pushed to its limits. Dipole equalization (or any other type of EQ) does not change that power requirement at all.
Dipole woofer systems are acoustically 'inefficient' relative to boxed systems, but that gets into another realm of trade-offs.

That's the (relative) gist of what Linkwitz is describing on that webpage.
