Full range tower speakers with bass under $10k

* 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.

The bass in some of the bigger Salks is produced by the built-in Rythmik Audio Servo-Feedback Subwoofer system.

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.

Will be selling a pair of Vandersteen 5 s soon.  Just saying
