HTF, I have 4 AC-2 (sold one already out of 5) speakers that I am selling for $400 each obo. They retail for $850 each. Excellent speakers. Originally designed to be a high end center channel, they excel at being every channel in a home theater system. http://www.nhthifi.com/home_productI...p?ProductID=50 Used for just over a year in my system, they all are in immaculate condition. The amp which drove them was an ADA MPA-501 which is renowned for its clean power. The colour of the speakers is black. Original boxes and manuals to accompany speakers. Since this is a pretty good deal, I'll honour first emails to me who confirm with payments. Regards, Gareth ================= Two 6.5" woofers, 4.5" midrange, 1" aluminum dome tweeter video shielded 48Hz - 26Hz, +/-3dB Impedance: 6 ohms. Recommended Amplifier Power: 30W min., 200W max.
