OK. so here is the REAL info on the Concert Grands.
they came in two variations.1 B-410 and other cabinet styles, they did not come with 15" woofers! only 4 12" and 8 tweeters,and two mid ranges now as the years have rolled on the tweeters have been improved,also the magnets has also changed on the woofers they started out with. Alnico and was switched to Ceramic magnets and the reason maybe the ability to source the Alnico magnets became hard to get. you could also get them in a Biamp version and the tweeter position was offered either in a center of the cabinet or on the side of the cabinet design, now one must understand is that most power amps of the time had low wattage and the voice coils in these woofers was a very simple design, now you will find some midranges have a flaking problem with their coatings that could be fixed.also Bozak gave you the option to build your own system in a kit form, Because people would also install them in their walls of their homes. Here is a bit of history! Mr Bozak made a speaker called Bertha and from what i read he had it in a room and a maintenance man was in that room and they did not know he was in there, well when they started to test the speaker, the poor guy did a number 2 on him self!!!!
I LOVE MY CONCERT GRANDS!!!!
