Behold- Digital crossover

You can do this with your PC. No need to spend 25 thousand dollars. You can build an HTPC that can perform the speakers crossovers, room correction, etc.

interesting stuff -I think. Behold is definitely onto something here. Also Goldmund makes a preamp that does this too, I think it's called the Mimesis 32 or something. Cost about 60,000 USD though.

Found the link to the Goldmund page: http://www.goldmund.com/products/mimesis_32

wish I had the money for that...

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.

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.

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.

Sure.

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.

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.

What is it? Do you have a link?
