Thanks
Yes i had saw that item and i believed the rb 75's to be somewhat better
than the rb -35'. but it has a 6" cone and the rb 81 has a 8" like the 75 so i felt like it was probably somewhere in between, but im willing to try the 81 if im not happy ill return it or purchase the 75 down the road. I have my setup in the main living area and everyone passes by this area and the 81` looks a lot better (WF) than the 75's with the grill sticking out like the others i have, which are not noticeable because there a long the front wall and where talking about surround speakers and not main so you can get by a little in that area., even when i run dvd audio disk there not always worked that hard except for a few exceptions.Steely dan aka Donald Fagen or some exceptions.I agree with your thought that the nob for performance would probably go to the 75's but looks to the 81 and sound not far behind. I should receive mine late next week and ill let everyone know my thoughts.
PS: I also heard that the rb 75 horn had been de tuned down on the rb 75 vs the other rc-7 2 x8" and rf7 2 x10" cones so it's output has been lowered a little to accommodate the one 8" cone so im taking that into consideration that the 81 will be getting close to it. Thanks for the info so far guys
