Linkwitz Transform with multiple/isobaric drivers

[Matttcattt]

How can I use the Linkwitz Transform spreadsheet to calculate the component values for use with multiple drivers, or multiple drivers in isobaric configuration?

I would guess I need to double or half some of the T/S parameters involved.

Any answers/links appreciated.

Well, when you think about it, multiple drivers with close spacing (wrt the wavelengths involved!) really act like a single driver. In the case of paralleled drivers both mounted on the baffle, they're the equivalent of a driver with the same Qts, the same fs, half the Z, twice the Sd, and twice the Vas. In isobaric, they act as a single equivalent driver with the same Qts, same Sd, same fs, half the Z (assuming you've got them wired in parallel), and half the Vas.

Thanks very much.
