Depends. Some sound great, some not so great, depending on the revisions. I personally love my 777. It has a very solid, double deck with great features, easy to work on, a modder's dream to build on & great looks. I think it is WAY under-rated by members here & I scratch my head when some say it's not worth the money spent. I turned mine into a DISCO Destroyer & loaded 2 OHM BOSE woofers into it with no modification needed to the AMP circuits. Now she pounds out 45w, same IC's as the C-100 & 2-OHM capable with ease.
The belts are relatively easy to change too & the cabinet has real working horns & bass waveguides to boost bass out put by about 3db vs a flat face, not to mention the independent BASS controls for a wide range of sound settings...
That being said this blaster is for parking on the patio & filling a room with sound. It sounds best when standing 4-5 feet back or more from it, not on your shoulder, walking around. The crossvers are 4.7uF & could use better 6.7uf Polyester Film caps for a more flat & smooth response.
What's not to love about that?
