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
This got me thinking about the volume I listen to when my partner is awake in a room on the other side of the house. So last night I measured. Quiet dialog is about 45db and I can differentiate it virtually every word. In the natural flow of dialog it gets to 50 db... occasionally peaking at 55. Any quieter and I start loosing words. |
@joeycastillo, your info motivated me to get a microphone for REW. Once it arrives, I have to work out how to use the software Robert |
@traubr I only have used UMIK for REW. maybe there are others, but I only use UMIK and using REW, I was amazed what i saw on REW when placed on my sitting position. in my case, the frequency response had a lot of Dips and cancellations. i just had to play around the DSP settings of auddesey and re-positioning the center channel and doing some room treatments and viola, the Diaglog became clear and i guess more dynamic. and REW showed me the changes.. i guess i just luck out and my problem was an easily fix.
again, YMMV. |
My speaker manufacturer recommends toe-in and I started that way. As the front L/R speakers are the mains for both HT and audio, I found toe-in was limiting the audio side. I got a very helpful CD from PS Audio (there are others out there) to dial in the sound for stereo. In my less than ideal space, where more toe in focused sound in the center, less toe in, e.g., facing more forward, created a wider and deeper stereo sound stage. With changes in equipment and cables, my speakers now face forward, and sound as good as they ever have with stereo. Go figure. Audyssey room correction helps to offset any imbalance for HT. There's always room for improvement, and I'm working on that. |
. I plan to also use the microphone for when I get Dirac, as they typically offer a Black Friday discount. Thanks,
