Kennwod is visibly worse:
-very small speaker (the membrane area)
-The ease of use is greatly limited (FB only with loudness control;! frequency setting on the system that is very difficult to access when Sub is permanently installed in the car)
-Bass Is not particularly clean (very fast highly distorted)
-the processing is good
-Price / Performance ratio is very miserable.
General:
The Pioneer subwoofer brings astonishingly much more powerful and very clean bass as Kenwood.
The TS-WX110A plays in a different league than the Kenwood KSC-SW01.
The Pioneer produces an amazing print. When properly adjusted (car stereo subwoofer) the bass come very clean, precise, crisp, but also soft and beautiful from the small box (with a corresponding music material). No rattling, no creaking, no background noise just bass.
Pioneer and Kenwood will go back.
