In Reply to: What is the problem with this 5.1 system? posted by Audio Girl on October 01, 2002 at 13:18:50:
#1 Here's the problem with the room:>>>The room has hardwood floors, no rugs or carpeting, stone fireplace, windows along one side of the room (no curtains or blinds), 10' ceilings, open area to kitchen, breakfast nook, hallway.<<<
Except for the 10' ceilings (that's a plus), it's too reflective. From the description of the room, you have sound bouncing all over the place. There are some non-audiophile geek things you can do to help with this situation: get a big throw rug for the floor, put up some curtains that match the room's decor, etc.
#2 Is the system calibrated? Did you set each speaker's level with an SPL meter or by ear? If you didn't use a meter, try this to improve the clarity and consistency in the sound.
#3 There are many DVD soundtracks that are notorious for poor dialogue reproduction. I don't know if it's the transfer of older (5 or more years back) soundtracks to the Dolby Digital or DTS digital codecs or just bad engineering of the center channel information. And, of course, it could be both. This has been observed from a properly calibrated hi-end system, so it's not due to poor electronics/speakers. In this case, if you're still having problems with center channel dialogue, after you calibrate the speaker levels as closely as possible with a meter, boost the center channel level by 1 or 2dB. This should be done as a last resort, but you may have no choice.
#4 Since you said "some" DVD movies, I believe believe you are experiencing the problems that I addressed in #3. If your system or speakers were the problem, it should affect more than "some".
The above suggestions and opinions are just that -- MY suggestions and MY opinions. I hope that you can get the performance out of your HT that you desire.

Yes yes yes!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!The Triumph Sig's are 91 dB efficient
The Ruark Dialogue II is 89 dB efficient
What it looks like is that your main speakers are more efficient. What does this mean? It means that with the same power, they will produce more output (sound louder.) For various reasons, it might be better to get a single Triumph Sig and make it your center channel if possible.If this is not possible, then use Joe's suggestion #2 of calibrating your system. Does your receiver have setup tones that cycle through your speakers? If so, then get a Radio Shack sound level meter (very useful) and sit at your listening spot, noting the levels of the front three speakers. You may notice that your center channel is slightly lower. Just adjust, and you'll be set.
As for this being movie dependant....yep. Movies are all amstered in different places by people with different ideas. This is why you need to have access to individual channel levels for every movie.
