Diffraction From Monitors?

[Chauvin]

I have got 2 sets of monitors in my studio which are placed next to each other?

For example purposes say 1 sets Yamaha HS80m and the other set is Yamaha NS10's. HS80's on the outside and NS10's on the inside with both faces flush/in line.

If I play music through the HS80m, would I get diffraction from the NS10 & vice versa?

Any help would be much appreciated as my brains going into overload trying to work it out

They will of course affect each other. Not automatically either a good or bad thing. I would just try them each way for a while. I would keep a fully open mind. You may find that either on their own sound better than with partners. Or not.

This is what I was thinking, just 1 set of monitors would be better as there would be no interaction with the other set. BUT, I like to have the 2 sets of monitors.

So what is the best way to place 2 sets of monitors?

By the way my room is fully treated, including desk reflections. I will put up a pic of my setup if needed.

the hs 80's mimic some of the characteristics of the ns-10 ... it'll be hard to tell ... a jbl/ ns-10 setup you would notice the Diffraction instantly ... like above .. move em around ...

The situation is too complex to make simplistic guesses.
If you are used to making sonic decisions, then listening is your best bet.
You could try measurement, but it will be complex.

I've moved the inner speakers around, back & forth etc. I can easily hear differences in the sound. I prefer when there flush with the outer monitors, but this might be because there is a slight boost in some of the frequencies due to reflections/diffraction

All I want to know really is, what is the best practice when placing second/inner set of monitors, so that it reduces any kind of diffraction or reflections to a minimum from my outer monitors?


Thanks for the help so far

If I had to make a guess I would say flush but with one speaker directly above the other. The flush bit would have a ver very slight similarity with soffit mounting. The vertical bit keeps interaction to a minimum. I could make up some other possible reasons to justify your preference, but as recording engineers we make sonic choices all the time. Best to trust that. The 'rules of thumb' often don't apply.

Thankyou very much for your help.

I'm going to try that out, give it a trial and see how I get on

have you measured for diffraction? any early-early energy present on the ETC response?

[Chauvin]

No I havent, YET. I have got my monitors set in place now, where I feel they aren't adding much diffraction (if any). I will do the test in the near future, just so I know exactly whats happening.
