Behold- Digital crossover

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 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.

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.

wish I had the money for that...
