After many months of pacing the floor, the MFW arrived last Friday. I wasted no time in dragging it down the stairs and ripping it out of the shipping box. I plugged it in, connected it to my system, and listened for the dreaded 60Hz hum. It was there, so I started to track down the source. Without the coax cable connected, the sub was nearly silent so I knew the source of the hum was either coming from the wall power or from the input. A cheater plug was added, and that had a small impact on the hum. As soon as I bypassed the BFD 1124, the hum went away. I had found the source. I added an RS 250-054 line filter to the output of the BFD and once again the hum was eliminated. Problem solved. With the ground loop isolator in place, I ran the Yamaha equalization routine and balance the sub with the rest of the speakers. All was good.
Now came the true test, how would it sound? I popped in my demo discs and ran through the clips one by one. With each clip, the smile grew wider. This is what was missing from my setup, the low end was extremely impressive. The clip of Darla tapping on the fish tank from "Nemo" made the whole room rumble! "Flight of the Phoenix" never sounded more realistic. Musical clips were also impressive, the sub was tight and deep at the same time.
I am very pleased with this sub and look forward to the next Theater Night to show off the new toy!
