Problems with Movie Dialog-Just the normal?


Hi all,

This is my biggest pet peeve with my system and would appreciate any thoughts-

When I setup my system via spl meter, all channels matching levels, the vast majority of movies have very low dialog levels, or specific instances where I can't hear dialog clearly, in the center channel. Drives me absolutely nuts. I keep turning things up until the loud parts hit the neighbors at the end of the block come a knocking. The distance to listening position is equal across the front.

I have tried to setup a balanced system, see system link. Equal power to all channels, the center channel is the same exact driver set as front mains housed in a horizontal array.

I'm torn between "how the director wants things portrayed-THX standards" and feeling "less-than" by flat out turning up the level in the center channel. Sometimes I've tried the late night modes and almost enjoyed these more.

I don't think the center speaker is "broken" in any way, all drivers make noise...:)

Any ideas?

Thanks
Marty

Yeah this is a common problem, but at least you have a multichannel amp with speakers by the same manufacture.

1)Buy the AVIA DVD, and crank the volume up to the level you like movies at, and run their sound tests with your sound pressure not the processors... since this is at the same level it will be accurate no matter what the difference sensitivies of the speakers are.

1.5)Check the speaker size it might be set to small and crossed over at 100hz, when it can handle large with the bass being crossed over at 100hz to the SUB. This will cripple your center channel output, but becareful with your first movie, listen at a lower volume to make sure you don't bottom out the center or damage your system.

2)Use the Phase check Avia Provides, you might have your center channel out of phase (wired or you processor might invert phase for you on your left/right speakers) this would cause the sucking out of the vocals big time!

3)Adjust the angle of your center channel if it is just sitting on the Big screen or sitting on a shelf below a projection, then the highs are being cut off... use a couple of rubber door stops and slide it from behind until the vocals snap into focus! This is really critical or buy a Sound Anchors Center Channel stand that allows you to adjust the angle/height of the center channel (I have this and it rocks!) If it is on top of the big screen move it forward to the edge of the TV to minimize the reflections and allow for the correct radiating pattern from the drivers(would you push your speakers to the side wall and expect them to image, same idea).

4)Lastly try to make sure you have the same interconnects and speaker cable on the center as the left and rights.

5)Remove the speaker grill on the center
Thanks for the ideas. DRC in not on, same cables between front mains and center.

The Sim Audio has surprising few adjustments/features with the menus. Honestly I don't think I have something screwed up, will double check. Their truly is not many settings to mess up.

I will try these ideas and see if I get an improvement. Think I'll bi-amp the stupid center mess and see what happens...?

Thats the spirit Marty, if it ain't loud 'nuff, shoot it some more juice.

Seriously though, thats a fine setup you have.
Distortion-I way too American. Bigger this, more that...

Seriously thou, when I simply turn up the level the mid-bass starts taking too much precedent. It's like the woofers in the center speaker start standing out, not just an increase in dialog levels.

How this can be affecting dialog only, I have no idea. Basically dialog is only a grouping of sounds right?

Also the system really only seems to come alive with excitement when the volume is way up there. Like 85% and higher. I dunno.

Thanks

If the center crossover/size is set to SMALL and Midbass is overpowering vocals, then I might suggest change the speaker itself. Maybe get your dealer to let you home evaluate a different type or brand. If the same problem persist then it is logical to assume the problem is in your electronics.

If your cabling will permit, you could try wiring a main speaker as the center and your center as the replacement main.

As previously mentioned by someone, make sure your phase is correct. Check at the amp and at the speaker terminals.
