Behold- Digital crossover

The behold is a preamp/crossover,room correction system.

it tends to be quite expensive around $30k.

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

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

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.

I do agree that clean well defined bass does benefit from some kind or room correction, however, you have to weigh the cost benefits of active room correction vs its benefits.

In many instances if you change the loudspeakers positioning and or listening seat position you can get many speakers bass to work wonderfully.
