I am going to say yes they do b/c of the amount od cone surface area being utliized. The Rev's have the horn throat coming thru the 10" woofer which takes out the middle portion of the woofer. I'm pretty sure that less surface area means less in Mid bass and lower frequency tone.
Since the Rev 410 has the horn and flare mounted in the center of the unit allowing total and complete surface area of the 410 to be used - you should get a little smoother and more promounced mid bass.
I have to say that having the Rev 10's on my tower - I do get all the Midbass that I am looking for and my sub makes up the difference. At the end of the rope, you may not be able tell much difference in mid pass production.
Have you seen the CIE boat - the put a rev 410 in the middle - it looks great!
