340SE center

I am 14' away

Sorry for the delay, I have been swamped.

At 14' back with a +8dB boost in the 125Hz range, your amp will be clipping at anything over 89dB in this frequency range. Considering the dynamic peaks in home theater sources, I strongly suspect that this is what you are experiencing. Cutting the amplifier boost in half (from +8 to +4) will probably still sound quite good and give you much more available headroom.

The large dip at 125Hz is most likely floor bounce. If possible, you might try changing the vertical height of your center speaker and then re-running Audyssey. This might help considerably.

Just an update to this......I lowered the 125hz Eq band from +8 to +5dB and changed the receivers crossover from 80Hz to 100Hz. This seemed to take care of most of my problem Dialogue sounds more natural now through the 340SE. Kinda weird that it helped.

This makes a lot of sense actually... Changing the boost from +8 to +5 gives you twice as much available headroom in your amplifier.

Do you think that changing the crossover from 80Hz to 100Hz would have helped as well?

Possibly, because I suspect that you are getting a lot of floor bounce in this frequency range and moving the crossover higher will send more of those frequencies to the subwoofer.

^^Interesting, thanks Dave and Happy New Year!

Pioneer SC-05 receiver... does no additional processing just passes the audio thru to my 340's

it would have to do some processing to decode the dolby stream from hdmi and dish it out to the speakers. have you had any luck with your issue? have you considered running it without any eq present? mcaac disabled does not necessarily mean an eq is disabled, does it? i don't know, i never used this avr before

It is a bit better with the 125Hz band lowered to +5dB from +8dB. Also, I upped the crossover to 100Hz from 80Hz.

The Pioneer receivers actually pass the audio "as is" from the source and apply not additional molesting of the signal to the speakers. I cannot say enough about these Elite receivers with the class D amps, they are great!
