The MiniDSP page talks about using a biquad filter.

A true classical Linkwitz Transform, as described by Siegfried Linkwitz, is a 2nd-order transfer function that can be implemented in DSP with a single biquad.

Whenever High Pass, Low Pass, EQ/PEQ comes to mind, my mind runs to analog filters...

Active Filters

A "rose by any other name".

In reality, the LT can be done via DSP or analog with boost, cut and high pass filters. The MiniDSP page talks about using a biquad filter.

bi-quads are applicable standard. I'd like to see the PM sent to Gigantic too for comparison.

BTW, the Linkwitz Transform can also be (cautiously) applied to vented boxes. I have an unpublished paper describing how, if anyone's interested.

Update of post #15: "Linkwitz Transform Closed Box and Vented Box Tutorial" is now available at Index of /gberchin. There are some other documents there that might also be of interest.
