Optimized Center Channel


Many years ago, I bought a seven channel AV receiver and speakers and voila!  home theatre.  No matter that my room layout is far from optimal or the equipment was more mainstream than high end.  Pop in a Blu-Ray and the system came to life.  My system is now 7.2.4 with very good electronics, and despite technology improvements and investment in better equipment, my home theatre experience leaves me wanting just a bit.  Don’t get me wrong, my system is very, very good, and I can hear Atmos at work much of the time, albeit limited by the audio track and ability of my processor to enhance it.  However, it’s not like sitting in an IMAX theatre and having your visual and auditory senses titillated.  But hey—my space isn’t the best and can’t change, my screen does not go from wall to wall, and I don’t have megawatts going into mega speakers and subwoofers placed all around the listening space to bombard me.

 

As DVDs have effectively disappeared, my HT entertainment is brought into my home via streaming.  I attempted to maximize the process with ethernet to fiber converters, a high-end network switch, a highly modified Apple TV-X streaming box, and quality electronics and cables.  Not the best money can buy (that’s not me or my budget) but pretty darned good.

 

HT constitutes 85% of my entertainment time, the remainder is audio.  The audio side of my house has dramatically improved since I first dipped my toe into those waters.  My latest and hopefully one of the last improvements on the audio side is a new amplifier, a Coda 16, which replaced a McIntosh MC152.  I really enjoyed the Mac, but the Coda is another level altogether (at triple the price, it better be).  The clarity, soundstage and power of the Coda puts a smile on my face every time I sit down for a listen.  It has also added considerable weight, punch and presence to my HT experience driving the front L/R speakers.  The dramatic improvement on the audio side made me wonder…

 

My hearing is nowhere near what it used to be, actors don’t enunciate, I watch too many shows from the UK (I suspect the problem is reversed when they watch American shows) and the dialog is not optimally recorded.  As a result, I have subtitles on all the time.  Surely there is a better way.  Thus, and finally, my question to you in the Audigon HT community: how to overcome the dialog dilemma.  Is a dedicated high-end/ audio quality amplifier to drive the all-important center channel the answer?  My Marantz AV10 processor is by no means shabby, but do the Storms, Trinnovs or Lyngdorfs of the world smooth dialog’s rough edges?  My center speaker is a Focal Kanta 2 connected to one of the three 300-watt outputs on an Emotiva XPA-11 Gen 3 amplifier.

 

I appreciate learning how others live with, or have overcome, the dialog issue.  Thanks for your time and input,

Robert

I’d still try disabling the center speaker and trying a phantom center, because if that sounds clearer/better it might indicate a problem with the center speaker.  Worth trying to rule it out I’d think.  Best of luck again in finding a solution — I know it must be very frustrating. 

First, that Focal sells a $4300 center speaker as a simple 2-way MTM design is an embarrassment — any center at that price should have a dedicated midrange driver.  Second, you have the center positioned with the tweeter well below ear height that cannot be helping.  You should try putting it on the top shelf below the TV or at least try angling it upward so the tweeter is aimed more toward ear level.   It also looks like it’s positioned off center so with a MTM design maybe there’s some comb filtering happening that’s further sucking out some clarity.  It’d also be interesting to hear if you disable the center speaker and configure the system for a phantom center if you still experience dialogue clarity issues.  Just some thoughts and some things to try FWIW — hey, it’s free — and best of luck.
