Since the advent of discrete multi-channel audio reproduction, along with subwoofers and the requisite multiples of required satellite speaker systems that followed, the proper set-up of surround systems in consumer's homes has quickly become the primary stumbling block to achieving a theater experience "as the director intended". Of the world's 60,000 theaters only 3000 have been set-up properly so as to earn the coveted THX certification.
With the introduction of the new Audyssey MultEQ set-up and calibration room correction system, home theater sound for the rest of us can automatically bring us much closer than ever to "as the director intended" while ensuring “every seat is a good seat” in the house.
I have never heard such a monumental improvement in the sound of an audio system as I heard with the Denon AVR-5805 with Audyssey’s MultEQ engaged.
1. Dynamic Frequency Allocation. What is the frequency range MultiEQ effects with a subwoofer, if any? Does MultiEQ equalize Subwoofers?
2. What other systems, other than Klipsch, were used to demonstrate the capabilities of MultiEQ? Can you provide them for review/discussion?
I read the attached article with GREAT interest. I have wondered for some time when ( and how ) someone would solve the problem of mathematically averaged processing to eliminate standing and reflected soundwaves through the entire listening area. I'm a firm believer in signal processing and wave cancellation. Heck, I go back to Bob Carver's rudimentary attempts in the early 80's with his 'sonic hologram generator', which I have in my old Carver C4000 pre-amp. While I am very anxious to experience the Audyssey MultEQ in real-world conditions for myself, my enthusiasm is somewhat tempered by the fact that it is currently only available in VERY expensive products, such as the Denon. Plain and simple, while I LOVE the concept, and will CERTAINLY love the result, I just can't afford to spend $6000 on a receiver right now. Hopefully, the technology will filter down to mid-fi in the next few years and/or they will market it as a stand alone component. In the meantime, however, if you need a volunteer to help you TEST one...
This sounds like a great piece of gear but the article doesn't mention the timeframe for availability or the price. Does anyone know?
Currently Denon has implemented this technology in their new AVR-5805 flagship ($6000) and it will also likely show up in their AVR-4806.

Yes is does equalize the subwoofers, independently infact! It will optimize the crossover setting, phase, splice between sub and center channel, 512 tap equalization for each sub in the system!
Klipsch speakers were used as an example of what this system could do with a well known speaker with a signature sound. Genlec were also used. Bottom line, is the better the speaker, the less correction the system will have to do.

Reading that article made me want that new Denon reciever. Badly. But Gene, do think that the reciever has enough power reserves to drive all of the channels with decent speakers? Or would it be a better idea to use separate amps? Not that I'm going to be buying one in the near future, but if I were to come upon a lot of money...

this new system sounds terrific and makes me want the denon AVC-A1XV all the more now!It even sounds like it may actually outdo the very complex and high perfomance room equalization system found on the lexicon MC12 v4...Gene what do you think?
I would like to see this as a stand alone piece that could be used with seperates, then I would be a serious player for it, but if I had to buy a certain reciever to get it I would't be interested
Whew...heavy reading for the holidays (for us non-techies, anyway)! Maybe that's why the lag in response.
Anyway...although the details are beyond me, it seems like a serious, scientific and cutting-edge approach to what really is the "final frontier" in audio: dealing successfully and systematically with the speaker/room interface. Beats the he** out of cables and expensive amps.
I'm sure we can expect it to appear in expensive "flagship" units like the big Denon at first but eventually filter down to the mid/mass market. I'll be waiting! I too would be interested in a stand-alone unit to insert into an existing system.
Ain't *real* science and technology grand?
