Digital Room Correction For Speakers

The Vandersteen 11-band EQ only effects frequencies below 100 Hz. Knocking down the big bass humps really improves midrange transparency, though. They just added a subwoofer to their line, the Sub 3, with the 11-band EQ, so you can add this to any speakers now.

I’ve been using the free DRC-FIR software for digital room correction with excellent results. I use Room EQ Wizard and a Umik-1 USB mic for the room response measurements. DRC-FIR produces a filter file from the room measurements that can be used with a convolution engine in a digital music server like Roon or JRiver (I use the Logitech Media Server BrutefirDRC plugin).

Legacy Wavelet which at full use is a DAC, pre-amp and RoomEQ is an outstanding example.  It can also be utilized only as a RoomEQ device with your own DAC and Pre-amp in front of it.  I've used it twice now with 2 generations of Legacy speakers with great results.  I have heard that Bill is starting to open up its use (or will) to pair with other speakers. Best to talk to Legacy direct about this and see where they are with this.

Any high end pre-pro (Marantz Onkyo, NAD Maaster, McIntosh, etc) equipped with Audyssey will work beautifully.   

Everything you can do to improve the acoustics of the room is what you should do first.

On top of that, well implemented digital room correction can be outstanding. I started down that path, then went 4 channels to add stereo subs, and now 6 ways to have the midbass in the towers on separate channels. 

How is your system configured? What source/s do you use?

Lyngdorfperiod. Rest of this stuff is Mickey Mouse. There are a couple much more expensive products out there too.
