Someone on the Asylum -- can't remember whom at this point -- uses a Lineaeum tweeter on his MMG's.
Quote from: josh358 on 29 Feb 2012, 01:58 pmNow, if you want a *real* blast, try turning them so they're edge-on to you, e.g., in a "V" with you at the point. If it works (it does in some rooms, not others) you'll be amazed at and blown away by what happens.Funny, I was thinking of trying that very thing out.

Funny, I was thinking of trying that very thing out. Not to interrupt the supertweeter discussion, but an update on the above. I didn't work. I guess I have one of the rooms it doesn't mesh with because it was more than terrible. I could see how it could work somewhere as the images outside of the speakers were great, but there was no center image, I mean none anywhere between the speakers, just a mush of sound. Because I was moving them anyway, for comparison I went through all the usual suspects using toe in's that have worked before and the "Perpendicular Placement" ™ is by far still the best. In response to JohnR's supposition, there is a slight reduction in HF energy, approximately like using the tuning resisters. Maybe I'll add a Linaeum supertweeter.
I'll be curious to know what you find. BTW, you could consider trying HP's rule of thirds......but my current room isn't big enough to allow it.
Just a thought. Is your phase correct?
Yes.And actually I appreciate the question. I have a zillion test discs both CD and vinyl, and correct phase is one of the first tests on all of them. But your question made me recheck, thinking how can I excuse myself out of this one if they're hooked up backwards, but the oldtimers hasn't got completely a hold of me yet, my system is connected correctly. However please don't take offence at the next paragraph.Which begs a larger question. As well meaning and polite as your post is, it brings to fore the idea that something must be wrong with me or my system, our long held audio beliefs cannot be wrong, speakers must face forward, at least in a general way. As mentioned by others, anything else is Bose reflected sound fields or you should be using headphones. So while donning my asbestos suit, I suggest anyone with planar's in a small room that doesn't experiment extensively is crazy. Caveats are I haven't tried this in larger rooms or with direct radiators. Okay, suit on, flame away, no offence will be taken.
Same problem, with the added problem that I can't read a calendar. So with the actual St. Paddy's day I was able to achieve some measure of success. I had thought the same thing about the thirds or something along those lines and with the speakers much closer together and closer to the front wall and the LP further out into the room the edge on worked pretty well, not the most preferred, but good. So with that success I continued experimenting and hit on a position almost edge on, but tilted in maybe 10° so you can just see the fronts of the speakers. Much better depth and realistic instrument placement with unbelievable width. Borne out in the Stereophile #3 Test Disc where an imbalance in the far right section of the 2nd cardioid mic test was now normalized.What I'm taking from this is that with dipoles in a small room, you can pretty much throw out any standardized placement rules used for direct radiators. I don't know if anyone out there is still taking this thread seriously, but everyone, toss your old ideas and experiment. It's free, it's fun, and what this hobby is about.
Interesting. We're still learning about this. Did you try various placements, e.g., moving the speakers closer to you? I found that it worked well (in the room in which it worked) with the speakers quite close to me -- in the rear half of the room. No center image problem when I tried it. The backwave was pretty much aimed at the center, which I guess provided center fill.And........Glad you found something that worked. A surprising number of people end up adopting edge-on when they try it. Also, parallel to the side walls can work, in my room it's the second-best configuration (after a conventional one).BTW, edge-on isn't the Bose effect! It's basically a reflected image of the speakers as far from the side wall as the speakers are. Then you have the rear wave reflection from the front wall, about where it is in a conventional setup. The effect psychoacoustically is to make your room twice as wide as it is.
I don't remember now which forum or what post, I think it was medium jim, but somebody mentioned Rooze placement to describe edge on. It got me on a search through the Asylum's threads (damn they're hard to navigate) and I found a bunch of posts describing several strategies. I understand more about the theory and have had some excellent success with it approximating the one thirds placement without measurement, just by ear and sight, but ran out of time last night. Now I have questions.One thread's diagrams show what I have now, out into the room about a third, LP the same from the rear wall, which would seem to use the front wall as first reflection point. Another thread, Rooze's original, seemed to say way further out, beyond halfway, and the LP centered between like headphones, using the rear wall as first reflection point. Another seemed to show almost in the corners of the front wall, using the side and front walls as first reflection points. Of course I'm going to try them all, but what has anyone still reading this thread had the most luck with?Presently the placement is on the long wall. However looking at the diagrams and comparing to my room, it looks like short wall placement may work best. Any thoughts from anyone about this?This is getting to be almost like a new topic, any thoughts on me starting a new thread, or is that overkill?
