    Re: Measurements on the Mackie HR624 mkII

    You'd be amazed at how little that top octave comes into play--or at least I was/am. I plan on doing some more measurements in a few days. Below 200Hz, it's room influence(dominated really) anyway esp far field. Today I'm building bass traps.

    I'm surprised that the general consensus seems to be polar response is useless for near field. I do a fair bit of recording and to me it seems at least as important as for any other distance. Interesting.

    Well, the Mackie just loses it over 10kHz off axis. The Behringer retains a smoother and more consistent off axis treble response, by a substantial margin.

    Again, for the typical (near-field) use of these monitors, this is irrelevant. But quite a few people seem to be using the Behringer as a budget mid or far-field speaker now, so this dispersion does become a factor in that application. From your FR graphs, there really is not much difference in overall smoothness of response between the Mackie and Behringer B2030P/B2031P.

    I would have liked to see a waterfall with 3msec time window, and 27-30dB actual resolution from the floor of the graph. Also, I would like to see a mid or far field response so I can see the actual lower mid-range to bass range curve.

    Chris, I'm sort of surprised by your response. Other than the top octave--the one that matters least-- the Mackie is considerably smoother and has much less diffraction. At least from your measurements on it and mine on the 2031p. Unless you just like the radiation angle of the 2030p.

    MSaturn, I agree. That mic does sound nice. My cousin has one and I used it for a year. Now it's back in his hands. Too bad for me.

    I'm not surprised; I use the Behringer C-3 microphone for recording live and in the studio, and it blows away stuff I've used at three times the price.

    Interesting, indeed. The Behringer B2030P has a superior response/better waveguide design.

    The Mackie is $480/ea. The 1030A is $100/ea. The 2031P I got for $152 a pair but you'll need amps. Watts are cheap, but the former are both biamplified with active crossovers. IMO, the 1030A is the screaming deal in this crowd, but when they release the 1031A, I might have to say that would be.

    Say you are 6ft from the monitor, the the reverberant field becomes important as well--even in the live end/dead end studio environment. At 3ft, head movement will be an issue--if you want to lean back, stretch your legs, lean forward to adjust some sliders, etc... There's no way to really avoid a smooth off axis response if fidelity is a concern. There's a reason most studio monitors are doing it. Certainly not d/t cost.

    As far as the Yammy's forward sound, that's why I wouldn't use them for mixing/mastering or even listening. YMV--no worries. I know many studios have the older version around, but that's part of the circle of confusion.

    It's amazing to me that even though that top octave looks nasty on the graph, I'd never know it if it weren't for the graph.
    Pretty sure that is because the top octave really doesn't matter, at least to the extent that a flat FR across the midband does matter. The lower and higher you go, linear distortion becomes less and less of an issue.

    As far as the "head in a vice" etc, I believe that "near field" in most studios is more like several feet - a degree or three is probably all the off-axis deviation one need worry about in a monitor design. At least, from the pictures I have seen of professional studios it looks like they are limited in how much they get off axis being surrounded by a bunch of little sliders

    In any event, what is the cost difference between the two (Mackie and Behringer)?

    I've never heard the 1030A.
    I've been waiting several months for the 1031A with a 8" kevlar woofer.
    Apparently, production for that newest model is way behind schedule.

    I had the 2031A's for several months, but sold them on eBay when I heard the Yamaha HS80M's.
    I've never been a fan of anything Yamaha, but their more forward sound was more to my liking.

    Don't know, but it does say the frame is magnesium. Seems Vifa did say that as well.

    Do these use Vifa drivers?

    Re: Measurements on the Mackie HR624 mkII

    In a subjective mood........I'd be happy with a fleet of any of them. I gotta tell you that I really wish that 1030A didn't have a defective amp on the tweeter and the rattling on the sweep. Even though the rattle wasn't heard during music. That broad polar response makes for nice listening. This is the most audiophile approved type speaker in the group--lush, detailed, spacious, etc... Their bass is a bit weak, but they are cheap. I imagine the Blades would sound similar. The Mackie feels like it's built the toughest and has remarkable bass. In fact, the bass is too heavy but it can be turned down with a flip of a switch. The Mackie or 2031P are great for imaging, but the Mackie do seem smoother an they measure the same way. It's amazing to me that even though that top octave looks nasty on the graph, I'd never know it if it weren't for the graph.

    Interesting stuff,

    I agree with everything you wrote. What's interesting to me is that it doesn't look like a better speaker than the much cheaper Behringer for its intended purpose. And, more interestingly, it doesn't look like a better speaker than the much cheaper Behringerfor use in a home audio or home theater system.

    Now maybe it is equal or better, due to virtues not captured in these measurements. Maybe, for instance, it goes lower, or its midbass has more throw or less dynamic compression. I don't know. But based just on polar response, I'd pick the Behringer.

    I'd actually say that for the near field, smooth off axis becomes more important as slight movements equate to a larger variance in listening axis compared to far field. Plus, if you're sitting at a console for hours, who wants their head in a vice.

    Where it actually matters, they are very nice. Studio monitors, do they necessarily need to exhibit perfect off axis response? You have a guy sitting there in one place, throwing little sliders up and down listening for stuff.

    Also, is the region above 12kHz extremely important? I think people place way too much importance on flat FR in regions that are composed almost entirely of harmonics. Kind of like in the bass region, a little raggedness isn't anything to worry about.

    Looks like a nice speaker for its intended purpose.

    Not just the top octave, but the vertical window is sort of narrow as well. Funny that the top octave doesn't play into my subjective impression. Look at these close ups of the tree monitors I've measured. The B2031P is the one I modified for a smoother less diffraction.




    Much of Dr Toole's book rings true as far as how these sound to my ear. Well actually all of it does.
