Passive vs Active...Again!

I am with you, I want to listen in a lovely room, yours sounds to be so. 

1. Toe-In will definitely make a difference, especially in your case, very similar to mine.

2. Tilting the speakers back will help in two ways,

a, most important, it alters the angles of reflections primary and subsequent relative to the floor, ceiling, side walls.

b. aim the tweeters so they project their narrower sound waves at seated ear height, primary listening position.

3. fabric, draperies, in the corners behind the speakers can help, any side windows that will cause early reflections

4. any large table(s), soft fabric tablecloth

5. Avoid glass on artwork on the side walls

we use tacky stuff on the bottom back corners to keep wall mounted art both level and vibration free.

6. tons of small cork/rubber/felt feet for small stuff hither and thither

You probably don't have a dining room table setup like mine, but have a peek at my setup.

My table, close your eyes, it's not there. as long as L & R get to your ears properly, your brain will make the phantom imaging which happily is excellent here. 

My Vintage Speakers have L-Pads, one for mid horn, one for horn tweet. Many in those days included them, for the purpose of adjusting to the room they ended up in: less attenuation for dull rooms and more attenuation for live rooms. And, your personal taste (or the wifey’s).

Are you finding current makers that provide for adjustments while listening in the space?

You are thinking modern software correction, and of course you can get a high quality multi-band parametric equalizer.

Sorry @high-amp I got carried away. I thought they were up for active discussion.

Room treatment purchased is expensive. Room treatment made is inexpensive and can be exactly the aesthetic your wish.

Sonos has many happy customers :-)

By the standards of this website, swarms are not expensive, but I don't know your budget.

But let's go back to those Spires. Floor to ceiling arrays, ESL, ribbon, etc. (or close to floor to ceiling) are more immune to floor and ceiling bounce. Why not look into those again. You do fix the response with DSP. Don't look at DSP as complicated, look at it as an extension to your hobby. Something to have fun with.

Final Thought, My Latest Kick

Buy an inexpensive SPL Meter, and a Test CD

meter doesn’t need to be perfectly calibrated, it gives answers, at ___ location this 1/3 octave is more or less than the prior and subsequent one, up and down the line. Move the speakers, adjust the toe-in, tilt them back, move furniture,

PATIENCE.

this test cd has selectable 1/3 octave bands, so easy

they come with holes for tripod, put in listening position/height, see what you get and see effect of changes.

not looking for perfect, just the best you can

elliottbnewcombjr - Great pics of your place and great suggestions as well. +1 on the PATIENCE thing...Thank you!

cindyment - Hey, no need to apologize, Kii 3s are up for discussion, I'm even negotiating as I write with a dealer 2 hours south that may let me have a demo! By the time you add up all the separate components and room treatment on top of that, I'm sure things would even out price-wise. Spires? Loved them but they need space off the back wall. I would probably go open baffle if I had the room again?
