monitors: horizonal vs vertical

[ds21]

Apples and oranges. Apparently, "power response" (in the sense you are using it) is a new term to describe integrated response curves in the entire room and using eq's to compensate for various response anomolies. It seems to be a home theater term to describe the integration of speakers in a 5.1 surround sound system.

Ok here's an apple:

A nearfield speaker (by definition) should be close enough so that room responses are not considered, because the listener is close enough to the speaker to not have the first reflections unduly alter the sound. Unlike your definition of the THX power response effect, the room is taken out of the equation.

After doing many acoustical measurments in my own speaker designing, and knowing that you have to use have a gated signal to get rid of the room response/reflections, I have to disagree with you here.

what matters is the environment and how they will sound in it. They might even sound good upside-down as the Mission studio monitors are designed.

Totally I agree with you here

If you want to find out more, I would suggest looking at some of the DIY speaker design forums online, some of which have MAJOR pro designers drop by, and some of the members are published in mags and AES. In fact you could help me shed some light on the recording process to them!

Nope, it's still an orange; they're talking about studio monitors, not nearfields.

Yes, if you're doing impulse testing of loudspeakers, you have to limit the window by gating; has nothing to do with this discussion, since nearfields are intended to take the room out of the equation.

Actually, I've designed quite a few speakers (and speaker systems) in my younger days. A few of them are still pretty well regarded, even today, more than 40+ years later.

As I said, we've drifted off the original question, and I certainly don't want to get into an argument here.

Do you have any idea who you're talking to here?

as the link above shows "Power response" applies to other speakers besides 5.1 surround, you'll also find it for regular consumer stereo speakers and pa speakers, but if you beleive it doean't apply to nearfield, oh well...

since nearfields are intended to take the room out of the equation.

Key word being intended.

I'll say, intended to minimize the rooms effect.

Yes, but I haven't seen anything to backup his statements, and no I won't just take his word for it (as nobody should just take mine), , harvey's right this is not the place to teach/discuss about such things. But you, Harvey or anyone else are welcome to chat with others with alot more knowledge then me.

Well, hopefully, the original poster got his question answered, and probably a lot more than he bargained for.

As far as visiting the speaker groups, I'll pass on that, since there's more "religious" fervor there than I can take these days. I only drop in on the JBL and Acoustic Control forums about once a month now, just too damn old, I guess.

The only thing I'm doing these days in the way of speaker design, is a nearfield monitor for one of the major manufacturers, then I'm out of the design business. I've been working on this thing for a couple of years now, and hopefully, it's gonna turn a lot of heads, if I can work out the final design and get the patents in place. The days really do get shorter as you grow older. I hope to see it hit the market while I'm still around.

Ds21, thank you for an interesting discussion, and we'll just hafta "agree to disagree" on some of the points raised.

I'm sure we could both find things out there to backup or dispove, but then if everyone agreed and there was only one-way of doing things sure would be boring. All this technical mumbo-jumbo aside, no matter how it's tested or what it's called, I think we can all agree it's the sound that matters.
