Room correction room system vs ears….

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.

soix , good question. Those front L-C-R speakers are ported and when I tried placing panels behind them it absorbed too much high frequency info and sounded flat.

I always assumed that rear ports were not carrying a lot of high frequency content.

holmz , I assumed that rear ports were for low frequency but just found in my room the high frequencies sounded flat when I had the an absorption panel right behind the speaker

@kota1 - I still do not understand what you mean?

What do you mean… and how do the ports apply to the statement:

1. The panels decreasing the distance, causes the port to reinforce gthe bass more?
2. The panels suck out later reflections, and the ports have nothing to do with the brightness?
3. Or something else?

im wondering if I simply messed around and found the sweet spot without a room correction system how much of a difference this would make. I’m far from savvy with audio and try to keep things simple for my simple brain, so, on a scale of 1-10 how much difference would I percieve by splashing out on a room correction system?

• If the room is troublesome then the room correction would make a big difference.
• If there is passive absorbers and bass traps then the effect of a s/w correction is less.
• Ideally one would do both
• Much of the problem is in the lower frequency room modes.

There are also the Dirac systems, which do impulse response and phase correction… so one can envision them as doing some EQ of the room, and some EQ of the speaker.

@thomastrouble are you talking about:

1. Room correction and frequency EQ?
2. Or impulse response EQ 

Maybe consider something like a TDAI 3400 or 1120 amp, which comes with a microphone and tunes itself up.

And there are probably cheaper options from NAD and others.

… going slow is often wise.
