What settings are you using with the EQ? Boosting the high end or the midrange? Unless you are a basshead, or attempting to cause earthquakes, boosting the low end of the B-199 is likely unnecessary, so I expect you're not doing that.
As I recall, and please correct me if I am mistaken, you are using a pair of the paper-cone B-209?
The paper cone delivers a slightly different sound and response than the aluminum cone B-209. Again, one should only use or purchase the B/Bc/C variants, never the A, which requires a special damping ring to reduce ringing issues and is consequently acoustically inferior to its successors, particularly after the ring has dried out or been removed.
The other issue is room treatment which can dramatically affect the sound one hears. This can vary with the height of the speaker, too. You have the Bozaks on stands? I saw you were discussing making some, but I don't know if you've done this. Raising them off the floor on legs will dramatically improve the sound.
