Planar speaker placement

Here's one for ya !  I bought a pair of Quad 2905 last week . I also bought a bigger Torus power conditioner and some cables at the same time . I placed the quads on the inside of where i have my king Sound King speakers . Been listening to the Quads since i got them home . 2 days ago i started listening to the kings again and i was impressed by something i had done . I was not sure if it was the bigger Torus or the new cables that was making the improvement . I started to isolate the changes to see what is causing the improvement in imaging and bass . Turns out it was the Quad speakers being next to the Kings ! Expensive room treatments !! I will be mimicking the quads with either a absorption or diffuser the same size of the Quads .
Anyone care to venture why the improvement ?

one speaker is driving the other

So much so good for the speaker industry !! Now audiophiles may buy an extra pair of speakers for placing next to the working speakers !

Multiple speakers (even idle) in the room affect the sound in a couple of ways. If large enough based on the room size, they will affect the acoustics just by placing them in the room. An idle (not connected) cone speaker driver will resonate from the sound waves from another speaker playing the room. It will affect the sound.

^^^^^
What does this tell you about dealers that have 6 speakers set up in a listening room ?


couple questions.

Is your phenomena being observed when the Quads are plugged in and when they are not?

What happens when the positions are reversed. Quads on the outside.

I can take a guess but this info would help.

@cleeds Well that is interesting and it made me want to check out your system page, but :-( yet another guy who hasn’t shared. Come on dude, let’s see it and maybe I can learn something.

Take a look at the Sound Lab site, I read it all and spoke with them, and at least with their speakers, they recommend treatment behind the speakers.

I’ll also helped multiple friends with Maggies and in each case they preferred having some absorption, diffusion or both on the front wall. Hey, if you get better results without, that saves you expense, cool. But has anyone ever seen instructions from a planar manufacturer advise the owner to NOT use absorption or diffusion behind their speakers? I haven’t. Cheers,
