Nice!!!My R100 isn't muddy but it lacks something. Maybe a little gruff, strained at volume, too edgy. The R40 was sweeter sounding especially after replacing the 10" driver with a Celestrion. Was significantly fuller with the upgrade..
However, the weight to watt ratio of the 100 is awesome. So easy to move around for the volume you get.
Which Celestion?
Is it lighter than the stock Rumble speaker?
