benefits of d'appolito
What are the benefits of a d'appolito arrangement? Are the changes huge/drastic enough, to justify spending twice as much money on drivers? Is it possible to use higher older filters than 18dB with them and maintain the benefits?
How much lower is distortion with a pair of drivers vs a single?
Im assuming the drivers would have different diffraction patterns, since they occur on different parts of the baffle. Does different positioning of the drivers detract a lot from the speaker (as opposed to a single position where there is only one set of diffractions)?
