Digital Room Correction For Speakers

Any room EQ can fix some problems but might degrade the sound on other areas because every component that implement equaliser manipulate the sound and harm the original recording .You should be very careful once you decide to buy room EQ it's better to check it in your system and in your room what is exactly its affect on the sound and if you like it or not.

Please take a moment to research how these EQs work and then ask yourself if this method sounds like something that makes sense and will not degrade your sound. Look in detail at how these EQs address the offending frequencies from the ones that dont have problems and how subsequent changes are made. A bit of research and a small amount of money will fix the problems permanently and without any downside. I think that the problem is not the equipment but how the equipment interacts with the room. 

I use a DSPeaker X4 in my system but only for the subs without any interference above 79Hz where it is crossed over. I simply wanted the best bass correction solution without interfering with the pristine signal to my main speakers from my own DAC regardless of cost. The X4 has done a stellar job, my bass has never been better. My DAC is an EMM DA2 and my preamp a Merrill Audio Christine. I did not want to interfere at all with the signal coming from these amazing components and going to my Pipedream speakers, so I run a second full signal to the X4 from the second output on the preamp (luckily Merrill Audio Christine has two outputs available!). The DSPeaker X4 allows a million adjustments, and I let it pick the crossover (79Hz) and had some golden-eared friends (thank you Merrill from Merrill Audio and Larry from Distinctive Stereo!) make the fine adjustments. So now I have 2 full signals going from the preamp to two sets of amps, one to the Pipedream's amps untouched by the X4 and it's DAC and the other full signal to the X4 for processing and then on to the subwoofer amps. It's perfect.

samgar,

In my prior post I asked which sources you used. This is important because if you had analog sources then a good solution becomes more complex. But I see you are only talking Roon, so that simplifies things.

As noted above, "solutions" can be as simple as implementing a parametric eq by ear on Roon to the DEQX-HDP4 soma mentioned. Of course with varying results.

The DEQX is probably the best solution, and also the most expensive.

But you have Roon that can convolve digital filters that were taken to correct for the room. Their effectiveness is directly connected to how those filters were developed.

I use a software called Acourate. Quite sophisticated and time consuming to learn, as it's super flexible. You need a mic and and mic pre, and analog to digital conversion. I generate the correction filters, then run them through HQPlayer in my audio computer. And have Roon in another computer feeding HQPlayer the music. Sounds amazing. The solution I think is on par with DEQX, depending on what hardware you use. Dirac is another good software solution, easier to use than Acourate, but less flexible.

But then someone mentioned there are services doing the measurements for you, so they could bring mic, pre and ADC, take the measurements, do the corrections, and provide you with the filters for you to convolve in Roon. That might be a good first step for you.

In my view well implemented digital room correction is hard to beat. I wouldn't live without it. As usual, implementation is the key/tricky piece.

Hi Sam,

    Try Room EQ, just remember your dealing with a multiheaded hydra. EQ is only part of the answer. The room is the problem and you may need more speakers to offset the standing waves in the room. 

Good Luck!
