1721h local library, keeps growing almost every week when new stuff that’s good comes out.

I’m sure there is but again, can’t help you since I have my PC hooked up in my living room with the TV and the speakers so I just use local files for playback.

Sorry, can’t help you there. I just run Dirac from my PC, have no experience with anything else.

Dirac does indeed do timing-correction so I assume it’ll help massively in your situation.

Might have a nasty room-mode or room-mode(s) in play. Might want to measure your frequency-response and even out the modes. My room, for example, is on the second floor and the house is from the 50s so it’s made of paper.

Used to get comments from downstairs neighbours at the time, ended up finding a +15db room-mode at 45hz.

Cute setup!

Turn down the bass, get a chunky carpet to reduce the echo in the room.

I know. A lot of people seem to just not care about room acoustics at all and just enjoy buying new stuff to get that high of a new thing to play with. Someone buys a new 5000€ amp looking to get a wider soundstage when all they could’ve done is set their speakers apart a few inches more for free.

Not ideal but better than a singular sub still.

I don’t think there’s any right or wrong answer when it comes to toe-in. Two different speakers will most likely end up having different toe-in depending on placement, driver dispersion, frequency-response and such so as long as you find the sound good it’s really all there is to it IMO.

But what you can do is try and write down the differences that you hear and describe them the best you can. I know it can be very difficult, I’m still in the same boat where I can hear a difference but can have a hard time telling if it’s a good or a bad difference. I just take my time with any change that I make, use it for a day, a week, a month, then change it up again and see how I like it.

Need to see some pictures of the setup to help out.

Rule #7.

But receivers tend to have a high output impedance (or at least they used to) on the headphone-jack that can indeed affect bass, making it more bloated and boosted. Some people like this, some don’t.

Changing to a dedicated headphone amp would surely clean this up, make the bass tighter but at the cost of less quantity.

I’d get some basic 100€ amp from a reputable manufacturer (Schiit Magni, JDSLabs Atom etc.) and test to see if you like it more. If not, then I guess a new pair is due.

I’d push the TV up against the wall as much as possible to ease the reflection from the TV. Then I’d add a rug, the thicker the better.

Next would be treating the back wall behind you. And if you can, add some sort of a possibly movable panel to the right in front of the glass door to kill the first reflection there if the left is open.
