10” forward firing subwoofer with large 1200W dynamic/2400W RMS amplifier. According to Velodyne (
http://velodyneacoustics.com/subwoofers/shop-by-room-size.htm), good for room size to 3200 cubic feet (with 8 ft ceiling, that is approximately 20x20)
I bought this about 2 1/2 mos ago as a recertified by Velodyne unit. It is cosmetically and functionally excellent. I got it to use in conjunction with my full range speakers as my tube amp wasn’t powerful enough to push the woofers deep enough. However, I have elected to go with biamping and thus, don’t need the subwoofer.
Easy to set up as it has a microphone and built in equalizer. One push of a button is all it takes. LED fromt panel so you know the settings (and light can be turned off). Remote control as well as manual control. There are 4 presets for different types of listening (movies, rock, jazz-classical, games) as well as a night setting so you don’t wake up the neighbors.
Price: 575+57 shipping (49 lbs)
