Greeting everyone.
Welcome to one more subjective discussion where I ask for your subjectivity.
Do I really need room correction? I have recently listened to the room correction (after callibration) of the entry level lyngdorf
(tda 1120 if I am not wrong). The calibration was done by a professional.
I could hear some differences but I have found those to be smallish. I also learned and I can confirm this that room correction does not improve staging. Staging is more affected by room and speaker placement and I have done indeed as much as I could for that regard.
My room measurements also show that I have kind of ok room and frequency responses is not all over the place.
Can I just survive with a more "normal" amplifier where room correction is not there or am I missing some important elements in my understanding.
Regards,
Alex

I use 'room correction' which prefer to call 'room adaptation'.
You are not correcting a room.
Okay so I use it only below about 500hrz and often just 20-150ish hrz with limited manual tuning above. I am very selective about what gets adjusted between about 150-500hrz limiting it to a balance of changes and letting the room affect the sound to some degree. Changing the vocal range so it doesn't match the room can sound canned and very unrealistic. Very. The room acoustics are often part of the mastering plan to create a sense ambiance. Especially studio recording. They have no space of their own. You room becomes the space via its own idiosyncrasies.
You also have to be aware of
SBIR from all walls and any very, very large items in the space. You prolly don't really want to adjust frequencies affected by that much.
Nothing comes close to properly adapted bass. 20-150hrz. I can't imagine at least a few key adjustments. Essentially no system has highfi bass without dealing with major room modes and to some degree SBIR(for which placement is very important)Also around 300 any big peaks or dips really affect vocals.
Above 300ish hrz I am focused on
speaker corrections. Which are in fact corrections not adaptations. These are based solely on anechoic data and personal taste. Not in room data which is not generally helpful as above the bass you do not hear the in room steady state.
That curve is not what you hear. If it was we would not need the anechoic chamber and the Kipple machine at all.
The curve is made up of everything all at once and not granular enough to be useful. It is a side effect.
The 400-500hrz zone might be SBIR/Comb filtering if anything is very close to a boundary @1foot or less(such as the speakers being close to the wall behind them or a side wall) It could be a character of the room or it could be issues in the speakers design. I would manually adjust anything there and take note any 'correction/adaptaion' might not sound better.
Just because you get a flat or smoothed line in a single in room steady state doesn't mean it sounds good.
I can put a tweeter in one corner, two woofers on the floor and a midrange hanging from a string in the center of a room and I might be able to tweak it so I get a nice curve at the listening possition. Will that sound good?
Not hearing enough bass through your monitors? The distance between your room boundaries and speakers has a huge impact on your bass performance. This tutorial will show you specific strategies for placing your speakers to get a balanced bass response.
