I'll bet you do (big cheezy smiling emoticon).
Let's agree that Chris as the CTO and founder of Audyssey, who partnered with Tomlinson Holman of the THX fame wouldn't say something bizarre. Indeed what he said word for word matched what I said: "For movies, the majority of the content is in the center channel. It requires the most dynamic range..."
Let's see, amirm wrote: "In movies, the center channel is dominant. It puts out massive amount of soundtrack energy. Ideally one would have 2X more power for the center channel. AVRs as such, need not apply."
Doesn't seem to match. Same topic, but I don't see anything in the former's statement indicating that the amp used to power the center speaker should have double the power due to a "massive amount of soundtrack energy," or that an AV Receiver isn't capable of getting the job done.
So if we apply your suggestion, double the power to the center channel, we arrive at what: a three decibel increase from the center channel. I'm sorry, but apparently I can't grasp the profoundness. If we're short of hitting the desired room SPL, then adding more power is one solution. Getting a more sensitive speaker would be the other (annoying emoticon with cocky smirk and black sunglasses).
But there is more. Here is Steve Guttenberg:http://news.cnet.com/8301-13645_3-10288323-47.html"Since more home theater speaker buyers watch movies than listen to music, I'll start there.
It's hardly an overstatement to claim movie-oriented home theater systems succeed or fail based on their center channel's performance and sound quality. The center speaker delivers virtually all the dialog and it can, depending on the mix, convey upward of 80 percent of a movie's soundtrack. The center speaker has a big job.
So invest 30 percent of your 5.1, 6.1, or 7.1 system budget on the center speaker, the Center Centric HT approach. As always, when it comes to sound quality, size matters. Bigger centers tend to sound better than small ones.
The subwoofer is the next most important player in a home theater sound system. [/b] "
He puts it even ahead of the subwoofer! Is it compelling enough now?
The argument follows: "the center channel is very busy during movies, therefore give the center channel more respect/money". Hardly a groundbreaking observation. I wouldn't rate Guttenberg's comment any higher than other vague generalizations concerning speaker systems, and most likely lower than any given advice on any given day.
You're very unlikely to improve dynamics by spending more money on a center channel speaker, whether staying within a speaker product line or moving to the next higher. So Guttenberg's advice isn't very pragmatic. In fact, center channel speakers aren't much, if at all, inferior to other speakers in the same product line when movie watching, with a subwoofer employed and speaker level adjustments made.
No, biamping or mono-block amping the center speaker for this guy. Keep working on those sales skills.
