I got this at a garage sale and it works far better than any thing I have ever had..suspect mid 1990's from
Acoustic Research
Model is
AR-2103
..but I can not find any activity on ebay or from manufacturer!
I believe a monitor would set on top!
The L & R speakers would separate from the center body which also contains a couple woofers.
Really well built...has mute button at left front..mic and headset jacks in front as well as in rear..is put together with a thousand screws!
thank you
