I guess I could add a few comments.
The BA210-3 design overall offers the low to low-mid punch you'd expect from a 10" based cabinet. Handles the fullness of a B-string with no issues. The Straight version will feel like it has a little more depth in the LF, but both the Straight and Slant versions handle the same frequencies. All of our SLANT cab designs tend to sound a little brighter with more clarity due to the geometry of the cabinet (less perpendicular interior angles than the Straight) and the fact that the baffle slants up to the player at 6% angle.
I've had the chance to compare this cab to other very highly regarded 2 x 10 and 3 x 10 cabs, and at approx 10 feet away the fullness and weight of each note really projects off the stage.
Frankly I don't feel that these cabs have a specific "tone profile" as they really produce what you give it with your instrument choice, amp, effects and playing style. With all the Bass Array designs that is the single most consistent response we seem to hear. "My instrument and tone only louder" would describe it.
I hope this is helpful.
