Full range tower speakers with bass under $10k

No, all modern B&W gear have an intentional dip somewhere between 2kHz-5kHz, even the 800 D3 models, but less severe than say the 600 models.  
  
Maple refer to this as the BBC dip, as the LS3/5A has it, but that had it as it’s off-aids wasn’t optimal, spreading the myth that neutral on-axis in that region isn’t ideal, it is, but the off-axis needs to be ideal as well. B&W speakers usually have great off-axis relative to the on-axis (which is what imaging is), so that makes up for it.

* Philharmonic Phil 3, wait time as it’s built to order.
* Salk SoundScape 8, also a wait time, but likely even longer, but it’s custom cabinet finishes/veneers (more exotic customization adds fees, they can be as high as $3000 upgrades).
* Revel PerformaBe F228Be

Those are the only ones I know of ≤$10K that can reach below 30Hz while still being a reference speaker. Also, the Phil 3 is actually 88dB efficient, it’s just instead of saying +/-3dB, he uses the -3dB point (at 25Hz).

B&W has an even brighter upper treble, so you must be talking about ~3kHz where B&W usually adds a dip in the response, some prefer it, but most don’t. Their speakers are also neutral, so I don’t see how they can be called top heavy, maybe you just prefer Harman’s target curve over say B&K’s, and/or you listen at lower volumes where we can’t hear bass as well, so then neutral bass actually sounds recessed.
