subs

Proper sub placement is number one, and using multiple subs just increases the WOW for special effects when watching DVD's. I currently use a Definitive Technology system with built in subs, and would add another sub behind the listening position for additional effect.
 
I'd say the number one thing to do is proper room placement. The number two thing is calibration/room treatment.

Of course there's always my favorite:

MULTIPLE POWERED SUBWOOFERS :cool:

(never enough bass)
 
Agreed, proper placement seems to alleviate the bigger problems on hand. An eq will come in handy to fix the little guys that dont want to go away :)

Proper placment of course...

Auto EQ is a cost effective way of smoothing out the responce at the listening position.

Acoustical treatments would be better but there wasn't an option.
 
Room placement is very important. probably the most important would be a properly built theater room with treatments and EQ.
 
You must spend some time correcting and tuning the sub to your liking. Most important thing to do IMO.
 
Finding the best placement is number one of course. My second choice was using 5 full range speakers. I figure that although you won't get the same bass response as a sub, the bass should at least be very smooth, which is what the question is asking.
 
like real estate, location, location, location
 
Subwoofer placement

subwoofer placement is critical to the succes of any home theater.

My choices were proper placement and multiple subs. In my experience those are some of the easiest ways to improve in-room response, although as others have mentioned, room treatments can be very beneficial. I personally use EQ to smooth out the response, but if I had the means for a second sub and decent bass traps I would certainly do that as well.
 
Proper placement is a no brainer. All acoustics entails is pressure waves in a cavity, and the easiest way to make them work is to put them in a good spot to begin with.

I said EQ for the second answer, but that was dumb. The second answer is room treatment for similar reasons above. That said, equalization is a reasonable compromise to working within a room, as long as you don't have some insane nulls.
 
# 1 is room placement. Find the flattest and most efficient spot for your sub.
# 2 compensate for the limitations of # 1 with an EQ.
 
It's definitely room placement, it can mean the diference between it sounding amazingly bad, to amazingly good. Even with the not-so-great Sony sub I have now, it sounds ok after I moved it around for a while and tested, again and again. Under the TV, it was horrible, super boomy.
 
in addition to room placement... I think you need to think about phase and proper matching of Sub and Mains (regardless of how big the mains are)..... 1.If the Mains are Big, then decide the "cut-off" and adjust the phase.... 2. If the Mains are small, make the "cut-off" as close as possible to the bottom limit of the Mains, and then of course adjust the phase... I guess you can let the auto EQ do this for you, but I think manual is better.
doing these two things will give better "smoothness."

my understanding is that the room dimesions and the sub's placement within it are the largest determinant of smoothness of response. An EQ can help to smooth any peaks created by the room.

I also agree with this statement
 
having 4 subs in each corner would probably be ideal, but, most won't have the money or space to do so. I have achieved a great sounding sub by corner placement and using a Barhinger Feedback Destroyer and carefully adjusting it for my situation. Dennis
 
Adding more subs and auto EQ get my vote. You can't ever have enough subs!
 
I think subwoofer placement in the room is improtant to achieveing good subwoofer bass response. I also think a disk of known low frequency test tones, a low cost SPL meter such as the radio shack analog meter, and a low-cost manual parametric equalizer such as the BFD, is also critical to achieveing smooth bass response affordably without compromises to the room decor and/or using more expensive solutions.
 
Getting the most out of my subwoofer is like buying real estate- location, location, location. I've actually raised mine up by about 2" as well. Hey, it works for my room.:)
