Altec studio monitors

I have traded for some altec 9846-8a speakers, can some one tell me about how old these are and what they might be worth. The story goes they came from an old rca recording studio but everything has a story.

I listened to some of the voice of the theater speakers but I liked these better.

The bass speaker has been replaced with I think a 15" cerwin vega. The bass isnt what Im use to. can I change the bass speaker of better quality. if these are very high sensitivity is the changing of this speaker very critical.

Hey if nothing else they are grey and black they look cool in my black listening room and they are cool at pool for parties.

You may visit the site link I have provided below for information on this speaker. Most likely the Cerwin Vega was used as a cost savings when the original Altec bass driver failed. Neither brand driver in this cabinet will produce flat bass much below 100 HZ.

The Altec driver would be a better match for the crossover circuit and may be found as good used stock or possibly rebuilt.
