Josh do planars require a different measuring technique as far as with a microphone and software, etc? Is there sort of a different way you have to go about it?
I think we can make a pretty good case that MMG's don't behave as line sources. The transducers are only three feet high and the listening position is most likely in the acoustic far-field for most of the frequency range. Thus, the SPL drops at something closer to 6db/doubling of distance vice 3db/doubling.Anyways, we're not talking about a planar versus conventional speaker comparison here.
if I sat at the same distance from the rear wall as they were from the front, it would cancel all bass modes below that frequency, in effect acting as a single bass array. I don't think very many people are aware of that effect.
Thanks for that, Josh. I have my room set up like that because the bass sounded best. Didn't understand the reason, now I do.
Well, the bass modes exist regardless of where your ears are in the room. But I understand your point. This does somewhat highlight the whole fallacy of "room correction" via "correction" to the loudspeakers response. (Bass or otherwise.)Indeed, the whole concept is upside down.....in my opinion.It's one of those silly audio buzz-phrases that's ubiquitous now. So, I don't think we're going to change it. Anyways, I did some testing on this a few years back and found that with MMG's the SPL drops off at about a 6db/doubling of distance rate very similar to a "conventional" speaker.
Yes, the DEQX is sort of a two-step process where you initially place the microphone near your speaker to generate a "speaker correction" profile and then pull the microphone back to the listening spot to create a "room correction" profile. (I apologize if I don't have the exact wording/terminology correct.)Anyways, who's to say what the original speaker designers objective was in creating the system response. Maybe he wouldn't appreciate a gadget like the DEQX "compensating for the shortcomings" of his design?Much of the fiddling I see audiophiles performing nowadays with gadgets to correct this or correct that is to achieve a flat frequency response at the listening position....at the expense of worse response elsewhere in the room. Is that really a valid "correction?" Is "flat" frequency response the holy grail? Is Davey off his rocker? What would a "correction" curve for a set of Magnestands look like?
