Help with sub

[jdbaker]

My sub amp just went kaput and has been sent back to Triad for repair. Without the sub I have reset all my speakers to large and it sounds pretty darn good. When I get the sub back I am thinking of keeping the speakers as large and my question is how to best integrate the bass of the speakers with the bass of the sub. I have 2 options for hooking up the sub, use the Theater input described by Triad as "For highest output above 35HZ". If I go this route what should my sub settings be in the C2? The other option is to use the line level inputs described by Triad as "For bass response fully extended to 20HZ." I would then have control of the sub from the sub amp, my controls are / input level/lowpass filter A/lowpass filter B/ and Phase control. I am assuming I would bypass the subfiltering in C2 setup and set the filtering on the sub amp. I am confused on what would be the best way to set this up so I thought you guys might be able to help.

how was it set up before you sent the stuff in?

The most common issue people have in your situation is calibration of the system. And there seems to be TOO MUCH of a certain LF, were both the sub, and mains are both hammering stuff out.

My initial gut reaction is to place it back to how it was.

Second, I would put it in the same inputs and mess with the freq cut off to ensure there is no "boomy" sections of the performance.

Additional information would be needed to really answer your question. Like are you running Triad Gold Omni rounds? that type of info. Most importantly what is the sub?

Snap,

Sorry about the lack of info. it is in my profile and I did not think to include it in my question. Triad inwall Silver 15 Sub, PSB CHS 60 L+R, CHS 40 Center (these are in-cabinet), Triad Gold Dipole Surrounds (in-wall), Halo C2/A51. I had it setup as speakers set to small and the sub connected by theater input and the sub filter set at 70. It sounded fine, but without the sub and the speakers set to large I am getting this wonderful bass. I would like to keep that and use the sub for kick ass LFE.

Thanks,

Would anyone like to describe how they have their system setup?

Thanks,

JD, I strongly believe in the principle of sending low bass frequencies to the unit that is designed to produce them--the subwoofer. So I've always set my systems up for all speakers set to small, the crossover somewhere about 80Hz, and calibrated/eq'd my dual subs for the room.

Go get yourself a Velodyne SMS-1. Or similar device. You will see the response of your sub and mains in real time. That way you can play with the crossover/phase/level/ and other calibrations until you get it just right.
It made a huge difference in my system.

Chris and Randy,

Thanks so much for the suggestions, I really appreciate you taking the time to help me. I had the system set up as Chris suggested before the sub amp flamed out and will probably go back to that setup. The Velodyne sub digital equalizer looks cool but a little complicated. Might have some trouble convincing the little women that I need a $600 gadget to tune the sub. Will keep my eyes open for a deal on that unit. Thanks again.

I use a Behringer Feedback Destroyer to EQ my sub. Like $150 or something.
