nirv,
you know what, initially i really thought na mahina lang, kasi parang i didn't feel it or note the difference, but when i went up to get something with the volume low lang,ABA, i can feel the vibration sa 2nd floor ko grabe, swabeng swabe pala, then even my wife, just to convince her of the difference, noted it when i made her listen to a same scene with and without the sub. Pati sya amazed!
thanks again!
