- Two B&O tower speakers

These are what B&O called Penta's. Very expensive for the period and self powered - so never really caught on around here.Having said that - I found myself really listening to these for the first time while installing display shelving in the listening rooms of the store I worked at. The guy I was working with and I sorta started out using 'em as a job site music source - by the end of the weekend - we were both pretty impressed!Since the rest of the center we were in at the time was closed - we could really crank these up - something I don't think I had ever done when demonstrating them for customers ( most B&O sold for looks). Penta's will play very loud , very cleanly and with something better than B&O electronics feeding 'em can sound remarkably good. Excellent combination of imaging ,detail and dynamics.
If I remember right - these do take some B&O specific connecting cord with their own "unique" connector. I also seem to remember that they could be driven either by speaker level (8ohm?) or line level (1.5V?)- depending on a switch on the base.
Not a audiophile speaker - but nice music would come thru them.Probably deserved more attention than they got in the late 80's - early 90's.
