Massive built downfire-type subwoofer with a
long-throw 20cm rubber surrounded bass
speaker.
Quite good response and loud on music and movies
too.
Compact size but powerful.The built-in amp is made
of discrete circuit parts,includes 2 piece of 6800 microfarad
puffers.
On some movies I need down the gain on the A/V unit because
the sub kicks a lot.I use its gain potmeter at 12o clock,
and remotes from the A/V unit at +6 dB.
On loud or full of action movies enough to drive at 0 dB.
