In Reply to: 2.5 also allows for higher efficiency due to using less or no Baffle step posted by Edp on April 9, 2022 at 22:08:11:
Topmost woofer crosses to the midrange. Middle woofer fills in the baffle diffraction loss. Bottom one supplements the other two at the very lowest frequencies, increasing bass extension a bit.
A clever and complex approach, and apparently successful judging from the reviews. Only trouble is, all three woofers are in parallel at the lowest frequencies, resulting in a wicked-low impedance. Only high current muscle amplifiers need apply.

- Consider the PSB T600 tower: a 3.5.5 way! - Brian H P 12:09:26 04/11/22 (6)
- Would all three woofers have to have the same impedance? - MWE 10:42:32 04/12/22 (5)
- Not necessarily, as long as they're the same sensitivity, but I think they're identical - Brian H P 12:50:07 04/12/22 (4)
- Sorry, didn't make myself clear, was talking more theoretically..., - MWE 13:49:54 04/12/22 (3)
- If you changed one driver to 16 ohm it would only change to 3.2 ohms - Edp 16:38:56 04/12/22 (2)
- Alas, 16 Ohm drivers are rarer than hen's teeth anymore - Brian H P 12:46:22 04/13/22 (1)
- A speaker manufacturer could have them custom-made in commercial quantities, but an individual, not so much. nt. - MWE 07:12:36 04/14/22 (0)
