I thought I would share my nightmare of trying to setup a subwoofer. If this could help someone else making this setup easier, great. If this could generate more tips and comments for the experts around here, even better!
I first setup my new system with 5 speakers and no sub (rti70, csi30 and rti38). The sound was great. But... there were a touch of bass missing, so I wasn't completly a happy camper.
So, I decide to add a sub. I wasn't willing to pay more for the sub that the others 5 speakers together... So, I let aside those marvelous sub that everyone talks about and went for a modest velodyne ct-10 (sorry Polk, my local store only carry the low-end PSW250).
Now, the fun part.... Trying to setup all of this together so that it sound good for any source of music or DVD.
I read and try many, many setup. Speaker connections, lfe, double filetering, single filtering, change the crossover level, etc....
Finally found out the single most important thing about subwoofer. It is writen all over if you read. But this would be a single sentence lost in all these other discussions about this.
The single most important thing is...
before trying to tweek ANYTHING ELSE...
where do you place the subwoofer in the room.
So, my recommendation to other newbies out there adding a subwoofer to their system system is:
- choose a cd that you know contain lots of bass and play it
- crank the volume up
- adjust the location of the subwoofer until the room stop vibrating.
Then, and only then should you start considering all the other discussions about subwoofer hookup.
Now to make a long story shorter, my setup end up as follow:
Main RTi70 set as large
Csi30 and RTi38 set as small
Bass management to LFE connection only
SUB connect direct to LFE (xover done by the amp at 90 htz)
Some reasons I endup this way:
- The way it is setup, the swf play about 50% of the bass and the main play the other 50%. I like the blending. The touch of low bass that was missing without the sub is now clearly present.
- By having only 50% of the bass going to the sub, I can raise the sub volume higher. The advantage of this is higher punch from the LFE channel for DVD.
I hope this could help someone out there.
If anyone believe that I made wrong statements here please correct me. Also, If someone thinks that I should setup my system diffently and this would bring me to heaven, please let me know as well!!! :)
