The newer SHD series can also be used to precisely integrate subwoofers, routing, and provide active crossover functionality.
Digital Room Correction For Speakers
Any suggestions for a digital room correction device which is easy to use. Or is it better to buy a pair of speakers which has the system built in such as Vandersteen. Any feed back is appreciated.
