Room correction room system vs ears….

Like most things it depends. With the right speakers and calibration software I've gotten a  flat FR from 30hz to 20khz with no special room treatments. Genelec 8351b using GLM and Dutch and Dutch 8c using their boundary settings and REW. I'd like to see what Kii3 can do, maybe someday. Anyway in your case I'd get a calibrated mic and REW since you're doing stereo. That can help with placing treatments. 

Room correction may make the sound better to your ears or it may not.  

One issue is the target frequency response curve it is trying to achieve may not be to your preferences.  

Another issue is that it will most likely try to fill in the valleys in bass response by boosting the frequencies.  Boosting bass frequencies can quickly rob an amplifier of dynamic power and cause early strain and clipping.  

I personally do not use it and if I did I would use it to eliminate peaks.  However proper speaker and sub positioning can do that quite well.  

Thanks guys , I’m about to start room treatment when I get back, heavy long curtains, bass traps, plenty of soft furnishings etc. what I’m gathering so far is over $1000 on a correction system is not necessary if I complete the treatment. I know that will tame the bass to a great extent but I thought the idea of a room correction system is that it does a lot of math and everything is fixed “before” it leaves the speakers - is that right?

Haye to spend $1000 only to hear very little difference.

I am not sure.

• Some passive treatments usually provide dampening of the sound after it is in the room.
  • One may want to dampen things out more where there are problem.
  • or diffuse things.
• Active approaches (EQ) gets the sound energy into the room at a more consistent level initially.

It is not clear that passive is better than active or visa versa.
A combination is more likely ideal.

And if passive is not an option for a variety of reasons, then active does make a difference.

I would think one might want to start with the microphone and measurements, rather than pillows, rugs, curtains and traps.

I had the DAC3HGC with the AHB2 once so I know the way it sounds. I now have the LA4 preamp and the DAC3B.

I use this system in my 12 x 11 x 9 office. So that is a small space but I have my closet filled with my desk and 6 monitors hooked up to 1 computer. Sounds like a recipe for bad sound.

However, I made the room sound great by calling GIK Accoustics and they helped me setup acoustic panels to tame the room. That is all I use now with my KEF LS50 Meta + KC62 sub. However, when I had a bigger speaker in the small space, a Thiel CS3.7 I also used DSP via convolution filters running on ROON. I do not need any audio hardware to run this DSP. I used a cheap computer running ROON in a room far away from the office.

If you are getting fatigue from the sound then look at your room. Acoustic panels could be all you need, but they are intrusive into the space. I did not care in my office. If the panels cannot be used in your circumstances or they are not enough then DSP will solve the rest.

Using the panels or DSP is always better than getting fatigue in a room that is not playing nice.

Something interesting on room accoustics

While I’m at it, I might as well include the latest measurements of my room / system. As always, these are collected using Audiolense and the help of @mitchco from Accurate Sound, who designs my 65,000 tap, frequency and time corrected, convolution filters. This isn’t your father’s DSP, to say the least.

Mitch also did the DSP for my office. That dude is a star at this and can do anyones room remotely.

Splish, splash you're taking a bath!

Might as well jump in with both feet

and buy the Professor's system as demo'ed

at Axpona in Janszen's room. Only $23k

as I recall. Tiny sweetspot. But yes jaw dropping!

Or buy a TigerFox enclosure for $500!!
