Center Channel Dialogue


I am looking for suggestions to increase the comprehension of vocals for my center channel. I realize many movies and programs are produced such that understanding the dialogue can be a challenge. 

My home theater is mostly Martin Logan: Summit X front, reQuest surround, LX 16 rear surround, SVS and Velodyne subs, and a Stage center. The amp for the Summits is a Pass XA30, all others use an Earthquake Cinenova Grande amp with over 300 watts/channel.

My issue is that I have to cup my hands over my ears to understand the dialogue. I have adjusted the Marantz 8801 pre/pro to maximize the output. I also use one channel of an equalizer to further increase output, and have also adjusted the different frequencies trying to improve dialogue.

I've angled and raised the Stage center the best I could. 

My question is, should I look at different center speakers? I like having all electrostats, and wonder if a substitute non-electrostat would match? Would a horn center like Klipsch make sense? 

Recently I considered a DBX expander, but don't know if that would help or hurt.

BTW, it's tiring holding my hands over my ears to understand the dialogue:)

I appreciate any suggestions.

Center Channel Speaker should be horizontal, located just below the monitor screen. Where is yours?

Stage Center, you mean Legacy? Sensitivity 102 db?

1st, how are you balancing the relative volume of each speaker to the others?

2nd, mixing brands, you can balance the volume, but the frequency response of different brands/model lines can result in a mismatch, i.e. front l and r reproduce frequencies with human voice range more prominently than the center channel does.

3rd, surround speakers may be too loud. you generally should not be aware of them but it should be obvious if you turn them off.

4th, your hearing. have you had an audiologist test your hearing? It could be you have a dip or two in the voice range, and a tone adjustment/equalizer/specifically tuned hearing aid can solve your situation. If so, you will be darn glad you found out and dealt with it, my close friend certainly is.

 

btw, your AVR probably has a 2 channel mode. I often find changing to 2 channel sounds better.

That will reassign the dedicated center sounds to both sides equally so that center content’s imaging is still center (but phantom center created by L/R), and still coming from the front.

And no ’other sounds’ from the surround/rear speakers which may be affecting what you hear (your cupped hands are blocking side/rear/reflected sounds).

Sometimes, in a noisy space i.e. restaurant, theater lobby, ... I hear sounds from a distance better than those right in front of me, seems like the other sounds are a precedent, fill my ears so to say..

" a 4.4.4 system, using the two front channels to create the phantom center channel image".

do you have a link to 4.4.4 so I can understand how it gets dedicated center channel info to the sides, that is a nice solution, especially for this OP.

for simplicity, let's say center channel is dialog.

I understand your method, HOWEVER,

that does not solve 5.1 movies/music videos, streaming. 5.1 has DEDICATED center channel content (mono) as well as dedicated L/R rear/sub out. The 5.1 center channel content does not exist in the L or R channels, thus, for 5.1 content you NEED a center channel speaker.

When you tell your AVR to use 2 channel/stereo mode (as I often do), it then reassigns the mono center channel content to the L and R channels  (dual mono) so a phantom center image exists as it does with our 2 channel music systems. The L and R are also making phantom imaging (a bit left/a bit right/center) like 2 channel stereo does. The rear and sub out are also moved to the front L and R, directional cues lost, but content present.

I see you can do that IF the particular AVR offers it.

I just checked a few Denon AVR’s on Crutchfield, manuals do not mention 4.1, perhaps the ’no center’ choice is there but unmentioned.

"Try setting it up for 5.1 and then go to SETUP MENU > SPEAKERS > MANUAL SETUP >SPEAKER CONFIG, and set Center to None (instead of Small or Large). I have the same model, and just tested this out with the first scene of the Godfather, which is all dialogue. With 5.1, the dialogue is all in the center, with faint echoes in the L/R channels. With the Center disabled, the dialogue was evenly split between the L and R. Can’t guarantee that it’s true 4.1 with all the center channel data folding into the L/R channels, but it certainly sounded that way to me. Good luck!"

HOW would this help OP understand dialog better? Seems to exist to omit buying/fitting a center channel, why else would you do it?

IF he is cupping his ears, then he is blocking the rear surrounds and reflections from them.

Perhaps they need to have their volume reduced in the menu, speaker adjustments

OR, go to 3.1 mode, omitting the rear sounds he is blocking with his hands

the issue is the OP, not me. Presently he needs to cup his hands at his ears to get ’better’ dialog.

It could be that he needs to get in the AVR menu and properly adjust his speakers. He could raise the center channel volume a bit more than the front left and front right. His rear speaker level ought to be generally ’non-apparent’ until he turns rear off. i.e. ready to do their job: Apparent for Black Hawk Down helicopter; Jurassic Park ...... in his case LOW.

Also, OP should try turning the REAR SPEAKERS OFF, by:

a. in the menu

b. change AVR to 2 channel stereo mode

......................................................

Me: I have 5.1 balanced, use it for ’true 5.1 source’, i.e. BluRay movies, Music DVDs.

 

Cable content: Some is good at 5.1, I often check ’Direct’, and may change to MUSIC 2.0 which frequently is better, coming from the stage. I think there is a lot of Pseudo surround, poorly done.
