.... aaaaaannnndddddd.... Part 3.

@7:45

I separate Directivity and Dispersion.

Dispersion: How wide the off-axis is.

Directivity: How the off-axis is in relation to the direct sound; the EQ-ability, what the Directivity Index of the Spins show us.

So, the Klipsch RP600M is a narrow dispersion speaker, and even though the frequency response is poor, it has good directivity:

I refer to dispersion as radiation. Mostly. Sometimes I interchange them. Again, just another point toward the video; how we mix and match subjective terms even with objective things.


Notice I also made a point to talk about directivity meaning the handoff of one driver to another in a speaker.

As long as we can agree the soundstage isn't chocolatey :)

Part two is up if you need 15 minutes to kill today.


A slight tangent but the "heard it from the kitchen" (or from another room), reminds me of some blind testing I did, which I've mentioned before, between some CDPs and a DAC. I found the signatures so distinct that I was also able to identify with essentially 100 percent accuracy which was playing, from another room! (Which, to me, actually makes some sense. If they were changing the sound as audibly as it seemed in the room, the sound should change if you are outside the room too, to a degree).

My wife didn't take part in the test, though. :)
