Several companies, such as TacT, SigTech, and Perpetual Technologies, are offering products that can digitally equalize your speakers to counteract problems in your listening room. Is this of interest to you?

They don't really work. Remeber Bob Carvers Hologram generator!I keep telling consumers all the time not to waste their money. Buy the greatest speaker you can possibly afford then back it up with an even greater amplifier. Put less and less between the original recording and the ear and you will achieve the best results. Try to use some room treatment and enjoy. How can these machines compensate for glass, relective walls and box like rooms. I know, they say they can do it. Bull!

It is not posible to have a truly high-end system without something like a SigTech. It's every bit as important as calibrating a video monitoring system.

Love my TacT Audio RCS 2.0. An equalizer is only half the story—you also need a device that can show you what's going on.

device would have to allow hand tweaking of results

Only for subwoofers though. Most rooms I've heard could use a little eq in the bass region.

have you reviewed these friends, your expert guidance is needed for if these equalizers work well and are sensibibly priced...inexpensive...who would not reach sucg magic wands.

More appealing is CD upsampling but once the "heart beats better", will consider this

I like to own one, but is little expensive. I can't afford it.

My analog 1/3-octave EQ worked miracles with my old speakers. I can only imagine what's possible now!

I'm constantly torn between single ended triodes vs. high tech high power new stuff. currently run SET with Lexicon surround...would add room correction if cheap enough & compatible with low power

I'm all for anything that can help my room. Just waiting for the cost to come down to my world.

I think this is a more interesting process than multichannel audio/video. Going this route continues to support high-quality audio products. Let's face it, unless your wallet is bottomless, how will you ever put together a decent setup with five or more speakers, amplifiers, cable, stands . . . On top of all that, DSP is getting more and more cost-effective, so the reality of room-correction will not be that far-fetched for the masses.

I wonder what digital correction would sound like when used in a cathedral? I guess the boys of the choir would sing out of tune!

The room is so much more important than cables, amps, etc. Moving speakers even a few inches changes the sound more dramatically than new cables or electronics. Taking the room out of the equation is eye/ear-opening. This has to be addressed to get sound reproduction even close to the real thing.

HINT, hope to see some digital EQ at the Montreal AV Show

I'm interested in room-correction, but I'm EXTREMELY interested in a digital equalizer that goes between transport and DAC for under $500.

The SigTech produces a sonic improvement that far outweighs any other electronic upgrade. The room is our biggest enemy, and the SigTech deals with the room better than any other electronic device or passive room treatment. Shame on anyone who spends big bucks on wires and electronics before purchasing a SigTech.

Andrew Johnson's picture

Where does the high cost of these products come from? I mean, most computers are FAR cheaper than any SigTech/TacT product, and since it's all digital manipulation, can't the costs come down?

I attempted to tame a few room mode peaks with a Z-systems rdp-1 digital equalizer-preamp. While not anywhere near as sophisticated as the products mentioned & not strictly a "room correction" device,I found taming the offensive modes problematic. Specifically, the modes weren't offensive until the volume reached a given level & you could hear the "dips" easily until the "optimum" level was reached. I felt you needed to set EQ curves (presets) for various volume levels to deal with the gradations of various room modes being "excited". All in all it was way to much tweaking involved & I moved on to dealing with the modes with room treatments. I would wonder if these devices can, with out a microphone constantly attached, deal dynamically with the changes in volume in the program material & the corelated excitation of modes. If the devices only "measure the room" during set-up & set filters based on set-up @ a given volume I would think the filters would be audible @ volumes which didn't get the modes "worked up". So I may only be demonstrating my ignorance of how these room correction devices work,but I have learned to be a "doubter" of digital magic when it comes to rooms & speakers that don't behave the same way @ differing SPL's.

First of all, I would have to digitize the output of my LPs. Second, there would be another set of digital connections to go through, which would presumably be some form of degradation. Third, for the price of all of this, the rest of the system could probably be upgraded to give the same level of improvment. The last point doesn't necessarily have to be true, but the audiophile implementation of just about anything ends up costing $$$$.

DSP holds incredible promise, but I fear we'll never have access to the hi-rez data on the latest formats.

I want both loudpeaker- and room-correction.

Hey TONY ESPORMA, curious to talk to you about your non-cd audio system. Please email me.

Dave W.'s picture

There are some room problems that cannot be overcome with room treatments. In those situations, well-done equalization might be an alternative.

Glynn Wilson's picture

I am always interested in anything that promises to bring me closer to the audio truth.

Gregg Collins's picture

I think this is just the beginning of the "equalization" revolution. I have a $50,000 system, and this type of room correction is going to take it to the next level.

As soon as it's "within reach," I'm there!

Michael J.  Rodriguez's picture

I still believe that the more you add to the playback chain, the more distortion you introduce into the sound. Even if the device in question is perfectly neutral (which is highly unlikely), the circuit path it travels—be it through interconnects, hard wiring, or circuit boards—will degrade the sound to one degree or another. Let's not lose sight of how quickly we abandoned these devices in the analog domain when we encountered that the sound degradation they imposed was greater than the benefits they offered.

Tip Johnson's picture

I would have bought one already if it was not for the uncertainty in the next digital format standard. The current systems are 16/44.1 while the next generation of digital is 24/96 (or greater)or maybe DSD (i.e., SACD.)
