  • Who's using Room Correction EQ and what's your experience?

    My experiences are with Dirac Live DDRC-22D (hybrid filters) and the PC based Focus Fidelity (100% FIR filters with adjustable filter lengths). Both solutions have made massive improvements to my listening experience.

    The Jamo R909's and my Clearwave Symphonia 1's speakers with Accuton Cell drivers both saw significant increases in fidelity. In my opinion a budget speaker with room correction will surpass any premium speaker without it. Even the lowly DIYSoundGroup Fusion 10's were more pleasing with room correction than my other speakers without it.

    Everyone else have similar experiences? And have you tried it?

    I love it, forget which audyssey the big Marantz uses, and it is not a subtle improvement. It integrates my dual subwoofers exceptionally, as well.
    Don't listen to me - I have not sold any $150,000 speakers.

      My Denon has Audyssey XXXXIVIXXI or something and Dolby Atmos 49.29-I'm being facetious. It works, it sounds better with it set-up and on than with it off very subjectively in my little living room with furniture and bad spots and no wall treatments. It prevents the "boom" in places (don't ask me how) so I'm happy with it.

        While I do not use it, I can see there is merit and likely benefits in some applications.

        I have 10' ceilings, walls that are old plaster, and a double/French door/archway to the rear of the seating area. In the middle of the room is the bass sucking abyss, but if you are not in it, the bass is fine. Plaster with horse hair is less reverberant than gypsum drywall. The high ceilings help a lot, and the no rear wall really helps.

          I've noticed a clarity across the whole frequency band and not just the bass where the room really affects the sound quality. As for the bass, low distortion plus room correction will really make a person wonder where the bass is however it's all there when the right instrument plays.

            Mine's not fancy, but my living room HT speakers are crap. Like, really crap. The exception is the subwoofer which makes movies and casual doing other stuff music listening enjoyable. For this crap setup I used the Yamaha YPAO calibration for the room, which is likely not as fancy as a Dirac setup but did a great job with tonal balance making the crap speakers tolerable. I've done REW measurements ungated in the room at the listening position and was impressed with how well the adjustments did. If you didn't know any better, and weren't listening critically you'd think the setup is awesome and it generally impresses whomever listens.

            Being a studio guy, I still hesitate to do an automated adjustment like that on my main critical listening spot or my studio monitor setup. I prefer to keep those flat without processing and focus on good speakers and room setup. But for less than ideal setups, correction seems like a really good option.

              I have what think is an room (just the main living room) kinda long and narrow so no side walls and plenty of furnishings but I'm a bit limited into how far I can pull my speakers from the rear wall. So yeah I'd like to play around with this as it sounds like Dirac is worlds better than earlier implementations of room correction.

              I don't entirely get how this is supposed to work, what is the best way to do this for strictly two-channel playback? My still working on building up my electronics but right now my source is a passively cooled Intel NUC HTPC running Windows 10 with a JDS Labs USB DAC. I also have Raspberry pi 4 that I thought about using as dedicated streamer to the DAC, but it looks like that Focus Fidelity software is Windows based? Would a Pi streamer work in that case or would Dirac need to run there instead?
