Behold- Digital crossover

You can use a vinyl source but it would be digitized so you will ultimately lose some resolution.

This is debatable but I understand the bias.

I have found passive room correction to still offer better results and is much less expensive in most cases.

This is certainly true but passive correction (physical treatment) can be massive and obtrusive in anything less than a purpose-designed room.

Actually effective room correction can be very small and attractive, the Acoustic System Resonators, work really well and they are the size of a thimble.

Shakti Hallograms also work really well.

My room uses a combination of these products with some echo busters, I have used Tact and other devices and I got way more improvement with the passive devices.

Sure.

I have a number of room treatments in place, but I think the benefits have been limited. The idea of controlling the speaker's output seems like the future. Recently I noticed a high end 3-way speaker with 3 pairs of binding posts.

I use both DRC and passive treatments, as well as subwoofers placed to minimze 1/4 wave effects. Lose the DRC and there is NO WAY to optimize FR below 100hz - at least in this room.
