I'm sorry, I should have been more clear on my above statement. Gene, I was only referring to the upgrade from /R to beryllium mids as that was what Warrior (I believe).
To the best of my understanding (unless RBH/Status price sheets, inside sales, & websites are wrong - which isn't outside of the realm of possibility as miscommunication happens some times)...
There is the SX-8300 with an MSRP of $5,000/pair - Soft Dome Tweeter, Aluminum Mids, Aluminum Woofers
There is the SX-8300/R with an MSRP of $5900/pair - Scan Speak 9500 Tweeter upgrade, Reference ALUMINUM mid upgrade, Aluminum Woofers.
The difference there is an additional +$900
BUT, and, man - how cool would it be to remove somebody's "Troll" moniker on this one, there appears to be a 2nd upgrade hiding on the grassy knoll. That is the upgrade of JUST the Reference Aluminum mids in the SX-8300/R to Beryllium for an additional +$800 MSRP.
Unless RBH has the mid description wrong on all of their /R upgrades in their speakers or is failing to call them beryllium when they should be (while getting the Status Acoustics description correct), this is the case. Also, the price difference being an additional $800 for the beryllium specific upgrade, when the regular speaker to /R components upgrade is $900 says to me that I'm correct, unless they are only charging an additional $100 for the Scan Speak 9500 and will do it ala cart.... But that makes NO SENSE.
Hopefully that explains my thoughts a little better on the difference in models, upgrades, & pricing. Also, until the other day, I had no idea there was a separate beryllium upgrade available on the SX/R products. It was only after reading Gene's comments I inquired because a client considering the 8300/R (whom reads AH) wanted to know. I was incredibly specific when I asked the upgrade charge to beryllium mids on the SX-8300/R and relayed my response with the +$800 to the MSRP.
Hopefully I explained myself and my thinking a little better this time around.
