My BIC performed just as well a top of the line Hsu.
If adding another subwoofer can infact do this for you, a mellowed out sub presense without the annoying big THUMP in movie scenes and without the annoying walls rattling etc, I'd definately go with 2 budget subs instead of 1 $1000 sub. As this may be the better way to go and the more "proper" way to set up your home theatre logically speaking.
Booms, bangs, thumps and bumps are all sound that's added to enhance a sound track in the sound room such as hitting pillows or watermelons with a baseball bat that we all know about. Along with a smooth room response, the subwoofer is suppose to sit in the background, unobtrusive to the ear, until called on to replicate the booms, bangs, thumps, clinks, clanks and explosions and do so at >96dB.....all of which needs to happen in a fraction of a second....."WHAM!" And then go away.
Being able to reproduce the lower, deep bass notes at "Reference Levels" is an achievement in of itself and to have large enough drivers and amplifiers to make this idea possible, costs a lot of money. Boys and the price of their toys. And then in one's home, with many listening positions, enters the need for several subwoofers, so everybody has the same listening experience.
To the right of the main listening position, is my wife's chair and her listening position measures +6dB louder than my position, so now we have to trade sitting positions because that's almost twice as loud for her and her hearing doesn't appreciate loud in the way I do. So, the net result, I have to put more effort into finding a way to smooth out the room's acoustical response to the output of our subwoofer system. Not every room is the same nor is every person the same as to what their expectation is of the Home Theater experience.
From the above it gets a bit enigmatic or esoteric as there's the visceral response to bass waves one can feel but not hear. There's the human response to lower base waves on the cusp of what one can feel/hear and then there's the bass waves one feels which is called "impact bass" in the >40Hz range which is what you seem to be referring to. All this is coupled with smoothing a room's response so as to achieve a flat graph so all frequencies are experienced equally. This, in of itself, is a challenge and then being able to reproduce the sound track as the sound engineer intended the track to be played back (THX standards), also presents a set of challenges.
In the above spirit, my recommendation to a neophyte would be for a 3,500 cu ft room, that opens to other rooms, would be to buy three $800.00 subwoofers and to take the time to acquire room measuring capability and learn how to integrate these three subwoofers into the acoustics of one's listening venue. In my opinion, excellent advice but not very practical as the neophyte doesn't know/understand the why behind the sage advice. So the advice morphs into a pared back version, start with one subwoofer if able in the $500.00 to $800.00 range, acquire room measuring capability, learn what they can and then purchase additional subwoofers as funds become available.
If it helps, the recommendation can be pared back further to a $300.00 subwoofer and maintain the recommendation of acquiring room measuring capability so one can learn how to properly integrate their subwoofer system into their sound system. A subwoofer system is separate from a sound system, just as tires are a separate system to an automobile but still a part of the whole. But, one needs to understand that in paring the recommendation back, the intent and purpose of a subwoofer system suffers accordingly.
Hope the above (long) ramblings make sense as I'm not trying to change your opinion but instead, if you're not already on to the above, I'm trying to along with others, share the why of it all.
