It is my understanding that to cover the widest seating area with reasonable imaging quality, you need to toe speakers in more, not less. More so the axes cross in front of the central listener and allows some flexibility in lateral listener positioning. This also produces the least wall bounce when walls are to either side of the listening space.The only reason to orient the speakers so you as a solo listener are on the frontal axes is if that's necessary to produce the flattest or most pleasant tonal response, otherwise there's no reason not to leave the speakers that way all the time.I never cease to be disturbed seeing big-buck systems (you know—the statement systems with the 1" machined faceplate pre amps and amps, the turntables with 50lb platters all on massive footers and carbon fiber equipment racks and $50,000 speakers looking like Darth Vader or some gigantic snail) with the speakers facing squarely out into the room—even near side walls. This is so wrong, and so easily proven to be. You don't need scientific proof—although that is plain and simple—you simply need to listen. A mono signal tells the tale. If you are not getting a coherent, tight, narrow phantom image in the centre with a mono signal, something is amiss and you are not hearing what the engineer intended when listening in stereo. If your speakers are close to side walls and pointing straight out from the back wall you don't need to ask 'what's wrong'. That is what's wrong.
There's more than one way to skin a cat... I do prefer a lot of toe-in with my horn speakers though. On the OP, I think the Pure Audio speaker is very dependent on the quality of the full range driver. If you like it it'll be a great speaker, if not it will suck. Most full range drivers aren't that great, but there are some out there that are amazing. Voxativ has always sounded ok but not amazing to me. Not on the level of AER, Feastrex or Omega imo... And after listening to a lot of coax designs they have their pros and cons too. Personally, I like the Ozone designs speaker better than either but I'd never own an OB speaker anyways.
Hi Dave, is Ozone actually a brand or design philosophy? Have you ever heard the Omega in an OB? That's something that I've haven't heard yet, but since I think Louis's designs are excellent I have no doubt they would sound as good as the Voxativ.
Did you build those? They look like some nice OB!How about if a speaker does not have a wave guide as in the Spatial and PAP offering?
Poseidonsvoice, thanks for the link to the Setup Speakers pdf. That is inspiration to experiment with more toe in with my M3 Turbo S. Right now I have them aimed right at my listening position, but the pdf encourages more toe in than that.
Ok I've learned a few things from it.I thought it was a true dipole but now I see its only from 800 down.I realize that the two 15" drivers are identical making this a two way, not a 3 way as I thought.So I guess this is an OB from 800 down and a point source from from there up in a wave guide......got it.
I have a pair of M3 Turbo S with a pair of GR Research dual 12" servo OB subs. I am pretty sure the M4 would sound about the same with these subs. That is to say, very good.
I'm wondering, since I use a subwoofer, if I could get by with the less expensive M4? As an aside, looks like the prices for the Spatials went up a bit. Better get 'em while they are cheap!!
you can build for cheap as the beta12cx are 50$ each the compressor driver P.audio BM 65$
