Man after my own heart. Room eq sucks the life of of decent kit. Better off matching kit up properly, placing it properly and cabling it properly.
If you play an acoustic guitar in your room, THAT IS HOW IT SOUNDS. You don't equalise it because cus it's to bassy in one seat.
We don't all sit in a recording studio, and when you go to a live performance you are at the mercy of where you sit.
Marketing is a wonderful thing.
I totally agree with Dav1dF most eq is poor, it's there because once manufacturer a offers it, manufacturer b has to to compete.
Nearly every time when I calibrate someone's tv I get asked to sort their av sound out. Every time the auto set up is used it's the same simple problems. Centre Chanel too low, rears too high and sub dominating. Audyssey sucks the life out of the sound IMHO and simple settings of Chanel distance and levels improve things dramatically along with correct settings of the amps crossover and doing the same with the sub controls.
Most people have not got a clue what proper bass is. The other mistake and yes this down room limitations is the main seat (usually) sofa is against the rear wall so you get room boundary bass.
To help here you place the sub in the main seat and walk round the room listening for bass nodes (places where bass rises, those are the places the sub should sit but you have to experiment to find a spot where the bass is likeable.
The other thing while we are at is is what is the correct distance to sit from a screen, the ISF trained answer is simple. Where do you like to sit. That is the correct place.
I do find it amusing that people spend a fortune on quality kit then destroy it with eq.
However, it's your kit, your ears and your personal preference, but I've yet to encounter anyone who did not think manual intervention did not improve the automated one.
With movies again I find it amusing. Take the film 2012. Does anyone know how the sound of the ground giving way with buildings crashing down around you while flying a plane through the middle of it SHOULD SOUND IN YOUR FRONT ROOM!
Your room is the room. Unless you build a bespoke one but that guitar will be a guitar where ever you play it and sound different in every room you play it in in your house or anywhere else.
