Digital Room Correction For Speakers

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!

I want to thank everyone for giving me feed back and words of wisdom in regard to my bass boom. I did go the route of the DSPeaker X4 digital room correction device and must say it has worked miracles to my system. My room being 24 X 26 with 2 different or should I say opposing cathedral ceilings and much glass is an audio nightmare.  The X4 reduced the frequencies between 70hz and 150hz by as much a 10db fixing the problem. The good news is that is did nothing to the mid range and treble. It is not an inexpensive device but for what it does, it is worth the price. 

Case closed! congrats. The only way I would have suggested yo sell those speakers is if we were neighbors and I could have taken them off your hands for you.
