looking for a more efficient speaker.....

The generality of stuff sounding better at or above 90db is certainly not true now. It might have been back in the 70’s with the relatively inexpensive equipment we were able to afford then. Certainly not true now as a generality.

What are the other components in your system? A system is the sum of all components  it might be better to swap the amp… your speakers are generally thought to sound very good. But that will depend on the space you have them in.  There is a place to put photos of your system and   venue. This is really helpful for us to understand how to help. 

OP,

Thanks for sharing your system. After giving it a little thought. The speakers are the most important choice in your system and largely determine the sound quality of a well balanced system (that is cost effective). Typically the speakers are the first choice and then all the supporting electronics are chosen. I recommend this approach.

Do you speakers sound ideal? If so, swap our your electronics to get the best sound out of them. They are pretty old. Perhaps auditioning speakers makes more sense. You want to find speakers that sound right to you… that you have an emotional connection to. Then, if necessary, swap out the electronics to get the perfect sound out of them. This is the shortest route to having a system that perfectly reflects your sonic values.

I would spend time auditioning speakers, until you find some that really connect with your emotional center. If tears come to your eyes… buy them… then optimize your electronics.
