According to Stereophile magazine, the top (‘A’ ranked) room correction or room EQ devices are the: Audyssey Sound Equalizer; Meridian 861 with MRC room correction; Rives Audio sub-PARC / PARC; SVSound AS-EQ1; Velodyne SMS-1 and the Z-Systems RDP-1 Reference. This article explores the pros and cons of each device from a purely functional perspective…here is an excerpt from the section on the SVSound AS-EQ1: “Designed for use with either single or dual subwoofers, the AS-EQ1 is based on a implementation of Audyssey’s DSP room EQ code. Plug in the included measurement microphone and install the custom Windows based software onto your computer and you are ready to go! Because it uses Audyssey code many locations in the room are measured (up to 32) before the correction filters are generated. This makes it particularly suitable for use in a multi-seat home theater where the bass response and therefore degree of correction required will vary significantly from seat to seat”
Today I’m going to look at room correction products specifically designed to be used with subwoofers only. Included in this article is examination of products by Audyssey, Velodyne, DSPeaker and SVS.
