Quite pricy, but you definitely get what you pay for! To be honest, I was a bit sceptic whether this tiny box could project the lowest frequencies enough (a bass needs to FEEL like a bass, right?!) but it's simply amazing: the RALFR (read the PJB website) does the job perfectly. Band practice with 1 acoustic guitar, 1 electric guitar (not too loud), lead and background singer: volume half way was enough, so. So even for band practice (the less brutal kind of music styles) this thing could do the trick for you. The sound is just superb: crystal clear hi-fi sound (no distortion whatsoever even at the highest volume!) but still with enough of that bass oomph which I was worried about. The build quality seems to be very decent (time will tell), and the thing just seems overall extremely well engineered. The only two comments I have so far, is (1) that they should have switched the AUX and the master volume controls (I always keep turning the wrong one!) and (2) the bass oomph that you hear through the speakers does not translate to the headphones. So when using headphones you need to increase the bass EQ to get a similar bass oomph. But to summarize: I'm very impressed.
