I know,there is no such best as golden rule, but to a person, who purchased a SW, the above question comes, where to start?

I have Marantz 6004 AVR and recently purchased a SVS SB12 NSD sub. The front and center speakers are from Epos with front speaker minimum frequency at 54 Hz. I connected between Sub Pre-Out of AVR to the LFE (Left) of the Sub with an Audioart Interconnect (which was lying with me since long).

I have set the Sub LF at max possible (i.e. disabled). The gain is set at mid level. and Phase is set at Zero.

I ran Audyssey and following results are obtained:

Front Left (-) 4.5 db
Centre (-) 5.5 db
Front Right (-) 4.0 db
Surround left (-) 3.0 db
Surround right (-) 2.5 db
Subwoofer (-) 8.5 db
The crossover is set by Audyssey at 40 Hz

The subwoofer is placed under a table with the driver facing towards side wall. After storing all the above settings when I put the sub on, the sound became more rounded than before (without sub) and the clarity of dialogue became slightly less due to background low frequency sound. Of course, the sounds during switching between front-center-surround speakers became more blended and rounded than before.

I am experiencing more homogeneity in sound but a bit loss of punch and sparkle to some extent.

I plan to change the cross over to 60 Hz and check. Any other advice?

Regards

80 Hz is a good starting point. I have set mine at 100 and I have set my front speakers to small (Even though they are actually big) and it works fine for me. After doing this if you are still not happy try changing the phase to 180. If both your Sub and Front are producing bass at same time they may cancel each other. So I would suggest setting the front speakers to small after running the Audyssey

More importantly 40Hz is not correct. I fyou front speakers can go down to 54Hz, your sub should be set at least 60 Hz. However 80 to 100 will be the perfect range
 
Congratulations on the purchase of the sub. I used to own one a while back and can definitely say that this is one of the best subs out there. However, this is not a HT sub. Its mainly used for music applications and thats the reason you had to set the crossover so low. What you will get from this sub is tight bass but not long drawn out reproductions that one may look for in movie scenes using ported subs.

With that said 40 Hz is too low in my view. I would play around 50-60 range as the in small increments. Also 80 is not ideal for this sub since its enclosed.

Couple other things that will help with the bass response is the placement and the amplifier. Corner placement is the best typically and enclosed subs respond well to high powered amps due to the work needed to push the air waves within the cabinet.

Please check if the Dynamic volume is on, then set it to off, the front-center channel volumes will not get faded if you do this with the LFE. You might need to manually adjust the speaker volume after setting the dynamic volume off.
 
change all the channel to 0DB specially ur sub that will boost the punch a lot and set the crossover to 80HZ to start with

note changing the channel level dbs wont affect audyssey calibration you just making it even, it happens to me all the time but make then all even to 0db makes a lot of difference
 
80 Hz or 100 Hz works well for me.

Play with the placement as it has a huge difference on the sound. For me the sweet spot is the corner of the room and not near the fronts or the center.
 
Any owner has dse 5.1 home theatre system.please provide the setting for my sub.there is volume,phase and crossover options.with lfe r/l port.
 
the best thing would be to use an rta and some test tones to configure them. there are avia discs which have lot of test tones to calibrate the sub for its crossover and its levels. try them with an computer based rta or a computer based sound meter
 
Thanks you all for your suggestions and help. Yesterday, I have changed the cross over to 60 Hz and changed the speaker setting dbs. The sound improved to our liking. Tried 80 Hz cross over also, but I liked the sound at cross-over at 60 Hz more. The earlier punch in sound has come back. The Sub, although could not be moved to any other place, because the present position is the only position in my room due to doors / furnitures etc.
All in all,I am happy now. Only thing I will do is to increase the Sub sound level from the present setting by about 1or 2 db and see the impact.
