Dipole setup tweak

This was posted on AA's Planar board and I thought some here might have missed it.
I tried this with my DIY open baffle dipoles and I like the results.
WAF went through the roof.
This makes large baffles a lot easier to implement and it sounds more "real". I'm still dialing them in but it's very promising.

How far out from the side walls do the baffles have to be? And did you notice if there was any difference between the drivers facing each other or away from each other?

It looks easy enough to try anyway so I'll be doing a bit of baffle shifting myself!

There was a large Wharfedale model based on this idea,
off-axis performance has to consistently good to work well.

Rather interesting. Basically, doing what this article describes you practically eliminate direct sound from the speakers (especially if angeling the dipoles at you where you sit directly in the speakers "zero" where no output occours) and maximise the rooms diffuse soundfield. I think Dr Amar Bose has a patent on that kind of thing.... Maybe he was right all along and we need ton's off diffuse sound and no direct sound to hear music well?

OK, well I'm still recovering from a nasty dose of flu so I can justify sitting down listening to music for most of the day.

I have tried my open baffles parallel to the side walls and the results are very good, certainly much better than I have heard from many so-called hi-end systems!

One thing I did notice was that the results were better with the listening position nearer to the baffles. In my case this meant moving the chair forward a couple of feet or having one of the baffles immediately in front of the fire.

The results are very musical although I found at the (small) cost of detail and soundstage definition.

I find my baffles are acoustically invisible most of the time but turned sideways, it was hard to realise that the music was coming from them at all.

I also tried swapping the phase around but it didn't seem to make a lot of difference.

One CD I listened to was the 'Amused to Death' album and was surprised to hear all the little sounds in their usual positions scattered around the room. However, they were not quite a clear as usual.

In conclusion, I prefer the more usual positioning for the baffles but if it was a case of getting rid of them or turning them 90 degrees to satisfy an unreasonable SOH, I would opt for the latter (or consider separation ).

I know you are being sarcastic but as you often say, give it a try.
This method is quite a bit different than the "direct reflecting" that Bose uses.

I agree they should be close to you and close to each other. I like them toed in toward me and facing each other.
