after 700 miles of listening (in the past 24 hours) i am very, very happy. they speakers sound great. excellent midbass. SOOOO much better than the floors were. doors are silent, no rattles or buzzed. not thrilled with them above 1kHz (despite having a "smooth response" to 5kHz). this may likely be the door itself.
sound stage is still good. not as deep as it was with floor midbass but close. the improvement in tonality is worth it. i will adjust the mids next.
I need to get my mids more on-axis to improve response from 1kHz-3kHz. they loose too much detail being that far off-axis. and they roll off at 3kHz. not that i want a lot more from them, but I do want the ability to increase tweeter/mid crossover points.
