Q-sound and dipoles/boxes

Pan · 15th November 2003, 10:37 AM

I´m a little curious about your findings/results with Q-sound and different types of speakers.

Roger Waters "Amused to death" is a record I use for fun to test a speakers ability to recreate the Q-sound. It seems to me that traditional monitor type speakers (watt puppy for ex.) manage to do the job better than dynamic dipoles a lá SL.

Anyone with experience?

Thanks!

I've observed the same thing- and it's not surprising, given the phase manipulation behind the Q-sound effect. On my last speakers (point-source box speakers), the barking dog on the first cut came from the side and behind me, very distinctly. The chirping crickets surrounded me. With the dipole line sources I'm using at the moment, the crickets are in an arc in front of me and the barking dog is vaguely diffuse at the side.

Hi

I have the same experience , with dipoles the barking dog
stays firmly at the right speaker.
Doesn't matter to me , tho , the dipoles sound much better

cheers

I wonder if these differences is becasue the contribution from the back of the dipole reflecting on the wall behind it or if it is something with the dipole itself..

Some recordings I have listened to have had a very open and realistic soundstage on the dipole but less so on a box system I tried with. Funny it was the other way around with "Amused to death", which didn´t work at all on the dipole but very well on the box speaker. Makes me wonder if the soundstage on dipoles "always" are fake... sort of.

I´ll put together a small high quality open baffle and listen to it in a large room far from walls to see if the problem is in the dipole concept or the back wave reflection.

I have just listened to the 'Amused to Death' CD on my open-baffle speakers and concur that the dog is located only on the right channel.

Over all though, the album sounded great on the di-poles. I found that the wagon and horses seemed even more real as they swept from left to right and off behind my right shoulder.

BTW, my baffles are about one metre from the rear wall and about 0.6 metres from each side wall.
