The X-Ref 12 is representative of the next evolution in Emotiva's powered subwoofer line and comes equipped with many upscale features such as built in DSP that is controlled via a top mounted LCD screen with a rotary push button knob, balanced XLR connection, and two fully adjustable bands of parametric EQ to address room response issues or adjust to suit listener tastes. The X-Ref 12 has a solidly built, well finished sealed enclosure with a hand rubbed lacquer finish. The 12" driver is a robust piece with a 3" voice coil and double stacked magnets which is controlled by the 600 watt highly efficient amplifier. Being a sealed subwoofer with a very small form factor the X-Ref 12 does not have subterranean deep bass extension or herculean output capabilities, so it should perform better in smaller spaces. But, it operates with rock steady reliability and always sounds clean and composed while doing so. Considering the bargain cost of only $599 shipped to your door for a subwoofer that does all of the above and the generous 5 year warranty, the X-Ref 12 offers a lot of bang for your hard earned buck. \n\n\nDiscuss "Emotiva X-Ref 12 Subwoofer Review" here.
