What affects front to back depth in room/ system?

@dsnyder0cnn my room measures 15’x19’ (4.57m x 5.79m).

The front of the speakers are 4’6" (1.37m) from the front wall. Middle of tweeter left speaker to middle of tweeter right speaker is 7’8" (2.3m). side of speaker to each side wall is 4’11" (1.5m). Ear in the listening position to front of speaker baffle (tweeters are at ear level) is around 9’3 (2.8m)" -same for left and right. I have about 2’ (.6m) from ears to the back wall.

The speakers are about 1 1/2’(.45m) closer together than what it would take to make an equilateral triangle, but this is where they work best (keeping the biggest emphasis on best bass and the right size mouth I hear singing the song).

@wolf_garcia ​​​​and @tablejockey I was just spinning the UHQR Aja tonight (just got it after seeing them with the Eagles last week). Man, if everything sounded as good as that album does, I wouldn’t need to fiddle with all these fidly bits.

@skinzy I’m starting to think the same thing. I’m really curious to see what the difference will be after I treat the room though.

@axeis1 I have Robert Harley’s book (which is pretty great) and of course Paul McGowans- which was quite helpful at the beginning.

@labpro Thanks for mentioning Acoustical Sciences Corporation. I checked out their tube traps a while ago, and was seriosuly considering those.

While we’re here- I’ve been thinking about going with Acoustic Fields (Dennis is who suggested I move speakers from the short wall to the long wall instead...which was a great improvement. The only thing is I don’t see any posts on here about them, but see some of the others. Does anyone here have experience dealing with Acoustic Fields/ Dennis or opinions/ feedback?

I don't think this can be oversimplified. It is a combination  of things. 

* speaker placement

* room treatment

*speaker isolation

* recording styles or techniques

*cabling

*music service 

*low noise in signal

I believe it is a combination of things.  Each helps but it is the cumulative result.

@veerossi - thanks for those dimensions. I don't see any issues. You are kind-of close to the back wall, but that's way better than sitting in the middle of the room, where you would experience bass nulls. Your gear looks great to me, so next steps are probably room treatment, as others have recommended.

Working out how much treatment is needed and where to place it is not rocket science. A few measurements from your listening position using Room EQ Wizard and a calibrated mic (eg., miniDSP UMIK-1) will tell you just about all you need to know. Feel free to PM me if I can help.

I am fortunate to have a relatively large dedicated listening room which allows for proper distances from the walls, This, along with abundant acoustic treatment provides for an immersive experience. I also use a distributed bass array akin to the Audiokinesis Swarm and I find that it further makes an enormous contribution to soundstage and depth.

I think the speakers have the most to do with it. Mind you I don't have a high-end system but when pitting kef r11's non meta against everything in the room at magnolia, one thing I noticed was that the kefs had an unusually deep sound stage..I wasn't listening for it, I just noticed it, and it was the first time I ever heard a deep sound stage and as you probably know all of the speakers are very close to the rear wall in Magnolia I ultimately chose them over theB&W 702s2s I have them set up in-between 2 rooms with about 12 feet behind them, using a Denon 4308, similar to the Marantz that they use in Magnolia, so nothing special.. the recording has a lot to do with it I found that with live jazz I can easily pick out the location of the instruments. Some many feet back,The whole sound is very layered.. and as one other reader had said, shutting your eyes makes a big difference especially at night.
