Hi Manu,

If you leave everything as is on the subwoofer, and set the bass extension switch to the '2 port open' mode, does it sound cleaner with this track?

With the subwoofer set to '1 port open' mode, one may hear some port noise (which sounds like chuff-chuff-chuff) at high playback levels with program material close to 16Hz. Or there is even a chance that the program material was low and loud enough to cause amp clipping (which sounds like brrp-brrp-brrp). Finally, if the driver is running into over-excursion, then one may hear a pop-pop-pop noise.

If that is the only soundtrack you hear audible distortion on, then I wouldn't worry about it. Just try to go easy on this soundtrack, and either reduce the subwoofer channel level or change the bass extension setting on the sub amp.

Sincerely,

sir its not with the above scene but every other heavy low bass scene and also even without playing the subwoofer and unplugging it and when i knock it off with hands i can still hear that tuk tuk tuk noise inside it may be something is loose inside it i also try 2 port open method but still hear that voice even at lower volumes
