Advice on room placement of Paradigm 100 v3 ??

I switched from B&W N805's (fronts), CDM CSE (center), and Leisure Monitors (rears).

I got tired of trying to get my subwoofer to fill in the midbass and bass. The 805's were incredible...and disappeared--they did MANY things very very well, but lacked some things too.

I fear I may have made a terrible mistake. I now have Paradigm 100 v3's in the front, 570 in the center, and adp 470's in the rear. My home theater is now rocking (NAD T762 Receiver--We can talk about an Anthem upgrade another day).

But I use the Fronts for "double duty" for two channel music as well (and here is where the problem begins). I have Rogue M150's, VPI TNT IV, CAT Preamp.

Anyway, the problem.... I have the 100's about 4 feet off the rear wall, 3 feet off the side walls. They are about 10 feet apart. Traditionally, I have sat at the apex of an equalatteral (sp) triangle for imaging and locking the center in two channel music. I CAN NOT GET THESE 100's to focus :(

I have moved my litening position further, closer--I have moved the speakers further--closer...still not locking.

Is it just that these things will never focus?

Can anyone give me some suggestions (besides "quit whining")

Thanks in advance.

or the more expensive digital version.

Get a Stereophile test cd2, or the better yet, the Rives test cd. Read the room acoustics basics on rives.com on how to measure the listening room(including the adjustment factor chart for the rat shack meter).
You basically play test tone cd, while reading volumes at the listening chair w/the meter. Each track has a different frequency recorded at the same volume. Chart your results on the graph you can print off rives.com.
What most rooms do is make the bass region way too loud at certain frequencies, vs. how it would be ideally. Speaker placement and room treatments address the problem. It's much easier than it sounds, and will probably shock you at how much your room affects your sound. Cheers,

I just tried these out at the local dealer. When I had the speakers firing directly at me, the focus was good. It was only when I decreased the toe-in that I lost that focus and high frequency air.

I know your post was back in September but, I hope this helps.
