Aerial 9B's for sale?


Does anyone know what an Aerial 9B is? I have never heard of the "B" designation applied to the Model 9, and I cannot find it on their website. However, two pair of them just came up for sale by two different sellers. Was there a modification made to the Model 9?

Your point is well taken. I thought someone here might know the answer, so I could find out without bothering the folks at Aerial. Since that didn't happen, I e-mailed Aerial and this is what they said;

"There is not currently, nor do we have immediate plans for, a revised version of the Model 9 -- there is no "B" model in the works. The 9 is one of our most recent, and most successful products and it will likely be some years before it is revised."

I have to agree with them. Mine sound great.
Swampwalker, you could be right, but my interest was in the possibility that Aerial had somehow improved on the 9's so I could upgrade if applicable. Contacting Aerial was the right move. Maybe those sellers accidently mislabeled because of all the "B" designations Aerial has given speakers in the past. Hopefully the buyers will research them and they will work it out because the 9's really are nice speakers.
I would be very interested in a review with some comparisons to other Aerials and other speakers generally.

Thanks!
SO I GUESS THE MODEL 8B'S ARE JUST AN 8 ONLY B STOCK AS WELL. THE SALESMAN TOLD ME THEY ARE 3 YRS OLD AND HE WILL LET THEM GO FOR COST ($3500.00 PR). I TOLD HIM IF THEY WERE DEMO'S THAT WERE 3 YRS OLD AND STILL THERE THEY SHOULD BE CONSIDERED USED.
The Model 8b was a revised version of the Model 8 that included changes to the crossover and internal damping.
