Speaker Placement - Frequent Placement Changes?

Slightly off topic: I run Duevel omnis which are generally believed to be far less critical on positioning.

Far from it! Even millimetre adjustments have profound impact on soundstage localisation and bass response as well as overall transparency. 

In addition proper room conditioning with bass traps in the corners and first inflection points as well as proper floor and ceiling damping have direc impact on proper positioning. 

checking once or twice per year after having established optimum poaitions tends to not,result in changes unless there have been major equipment changes.

@elliottbnewcombjr great post with pictures.

For whatever reason, I thought you were using Cornwalls, but you’re obviously using DBX speakers - apologies, I was fading pretty quickly last evening. 

 

For my Main 2 Channel Music System, for two listeners, I alter the toe-in so each listener is closer to one side, yet the dispersion is more direct from the other side, which works quite well.

My speakers are over 100 lbs, on 3 wheels, the tops are tilted, Donna’s stuff on top, they stay put, nothing vibrates off them, yet I am able to re-position them as needed. (I used spikes in the past, I perceived no advantage, flexibility was lost).

toe-in for one centered listener

Unsure if this is similar, but I’ve played around with extreme toe in with my Tannoys with the axis crossing 12” in front of the MLP. This accommodates two people much better since we’re both allowed phantom center imaging. Since my spouse rarely listens with me, I’ve settled with minimal toe in with the axis crossing 12” behind me. In Tannoy’s manual they recommend extreme toe in, but I’ve always found myself going back to more “traditional” toe in. I suspect, and I could be wrong, that part of this recommendation was to accommodate normal living environments that typically don’t include room treatments, especially at the first reflection point.

toro3 OP

I have 1 room: 2 channel music one end, small home theater across the other end of the room. the 2 chairs in the middle simply turn around as desired.

dbx soundfield 100’s are for the home theater.

I use their principle of cross dispersion with my music system sealed box speakers.

They are Custom Made, similar to Cornwalls, 15" woofers, horn mid; horn tweet, but the innards are all electrovoice drivers, crossovers, L-Pad controls.

here’s the innards

the parts all came from a 1958 Fisher President II Console I inherited from my Uncle Johnnie in 1973. That’s how I got hooked on great sound and tubes

The unit was up on 8" bronze legs, the woofers fired downwards, I made taller enclosures to face them forward, increase cubic feet, and a rear vent that is closed here, it was open in prior location with no wall behind.

I have a pair of Acoustat 1+1's and they're pretty darned persnickety about placement with regards to sound stage. Add in the inevitable requirement for compromise in a shared living space, in this case the living room, and my options become more limited. A couple of weeks ago my spouse noted that the speakers seemed further in the room. By two inches. "Really hon? I hadn't noticed..."

That said, they are pretty much in the ball park where they are usually so good on me. 

Additionally, because they are so sensitive to placement every few months for fun I tweek them a bit for a different stage. Accutely toed in they produce a fairly wide sound stage. However, seemingly counter-intuitively, if I open the angle a bit the image becomes pinpoint sharp in the center and moving my head either way skews the sonic image. It's pretty amazing really.

Anyways, nothing productive to add to the post. Just wanted to chime in. 

Happy listening.

Wives should come with Wheels for Speakers!
