Infinity RS 2.5 speaker placement

Hello all,

I've been trying to find the perfect spot for these old behemoths. I have tried the Cardas website, but the formula doesn't seem to work perfectly for these, maybe because they are a mix of cone woofers and the mylar? mids and tweets. He suggest toe in for all speakers while the infinity set up manual says to keep them parallel. Room is approximately 11'x20'x8' rectangle. Big window in front that has been covered and also some crochet blankets on the walls to try and soften things up a bit. I'm looking for the best imaging and soundstage I can get out of these. Any help is greatly appreciated. Btw, it's not bad by any means, just trying to find the best way to set up these speakers.

Wow. I actually owned a pair of those years ago. Great speaker in their day...

I agree with Elizabeth. Start with them about four feet out from the front wall (wall behind the speakers).

BTW, they are not a dipolar design. They are a bipolar design having a rear firing EMIT tweeter in phase with the front firing EMIT. Anyway, they require tons of power to "wake up" so feed them lots of good, clean watts! Of all the speakers I have owned over the years, they were the most power hungry. And I own / have owned Magnepan and Apogee!

Be patient. Good luck.

They get about 450 watts a piece from an edge nl-10, so no current problems. I have them 5'2" to the center of the woofer from the back wall and laid out by the cardas formula. I will just have to fine tune it by ear. Thanks for the responses

I had a pair of 2.5's for quite a few years. I replaced their vintge tweeter & midrange capacitors with modern polypropleans.
They image better when not too far from rear wall due to rear tweeter; I had mine 41" (wall to front).
Lower bass was great, but upper bass was weak due to crossover design (an equalizer would benifit here).

Don't set them too far apart either.
