This Sunfire True Subwoofer MkIV is in absolutely OUTSTANDING condition! Both cosmetically and operationally. Whew! That 2700 watts can move some serious air! The Mk IV is an upgrade to the Mk II and the middle child in Sunfires family of active subwoofers. The compact 11 square cube houses two 8 drivers and a 2700 watt amp. The high wattage comes from Carvers nifty little power supply that rises to the occasion, so to speak. Hookup options, volume, crossover and phase control are all available as they should be. The Mk IV sufficiently fills in the bottom end from 40 Hz down to 20 Hz without over-emphasizing the bass range above 40 Hz. With the volume on the sub is properly attenuated, the low end is fleshed out properly and without a lot of boominess. Turn it up a bit and things begin to shake, rattle and fall. Impressive, yes. This thing is capable of moving some air, but fortunately can be reigned in to add just the right touch of natural low end. Most impressive was the speed and tight control. Shipping to US ONLY
