Ok so replaced the speakers - the Patriots have eight screw holes so the alternate four are open but it still seems to seal quite well against the Cube speaker cutout.
To me, the bass is more pronounced but I'll let listeners be the judge. I used the line inputs which are flat EQ, and used the same app and beat with the iPhone recording in the same spot and at the same level, Just used the simple recorder app in the phone.
Left recording is Eminence, right is Roland, which although less "bassy" has more clarity. When I played using keys bass and drums, the Eminence stood out...lot more gain before going flabby!
I might re-do the audio but with proper recording...this was just a "quick and dirty" test.
The picture shows a marked difference in the size of the magnet, so I am not really surprised bass response is better.
