Show me anyone who has a 2-way or 3-way monitor in your price range that can go down flat to 35hz and I'll show you a liar!
I think you should be realistic about the bass capabilities here of floorstanders, too. Unless it's got a transmission line cabinet and at least dual 12" woofers, 35hz is just not going to happen!
I agree with just about everything you say. The OP's original requirements are unnecessarily restrictive and nearly unrealistic. A small floorstander with the proper backwave management and room boundary reinforcement could get him where he needs to be.
And although 12" woofers can slam out a lot of bass (in an appropriately large (say 9 cu. ft.) cabinet, there are plenty of speakers that make it flat to 26 Hz or lower with a pair of 8" woofers. Two examples are the Wilson Sasha W/P and the Mirage OM-28. My 1996 Mirage M5si's are dead flat to 29 Hz with a pair of 6.5" woofers.
+1 for the transmission line, but the Atlantic Technology AT-1 makes it past 35 Hz with a pair of uniquely loaded 5.25" woofers in a D'Appolito array.
