I'm more concerned about the broadband dip from 150-1K or so. Broad dips (or peaks, depending on your perspective) of 1-2db aren't a problem for hifi speakers, but my objective is to have a fairly accurate reference for dialog.
I got the speakers today and have them set on my desk. The sound is very good, although there are some caveats -
1. Not atmospheric like good hifi speakers; sound is very specific in quality, center image is very solid. Image extends past the speakers but it doesn't sound like the room is involved. This is probably a good thing, but I tend to like more atmospheric speakers. These are the first narrow dispersion type speakers I've really listened to - my main speakers I made use a dome midrange, which I like for music.
2. Instruments have good texture, percussion is very dynamic for a small speaker. Things start to break down at very high volumes, but SPL is more than enough for desktop use.
3. Bass is exactly what I'd hope for this speaker - many small speakers have a pronounced bump around 60hz or so, but this measures and sounds fairly smooth here. Low bass is limited, which again is a good thing for my use.
4. Horizontal dispersion is really wonderful. If I put my nose up to my monitor (directly between speakers) the sound doesn't change much, center image is still there. Moving back things get a bit narrower, but I should probably toe them in a lot more or a bit less.
Sound exceeds expectations, but vertical dispersion is poor. You definitely want these things pointing up at you if you're tall like me - I have them on yoga blocks on an angled desk, so they're pointed down at my chin almost. When I crouch over sounds is much better. The other issue is noise - I wouldn't say it's a problem but it's there. I haven't played with all the different gain options though, and the speakers are quite close. I'm not concerned about it. Many good classical recordings have far more noise than these speakers. Pop/Rock/Recording Studio Music sounds great.
So, my one hour review - amazing value for the money, very usable for monitoring, but not high end either.
I suspect for the design to be significantly better you'd need much more expensive transducers (Wavecor-Rival-SB level) and charge about 2-3 times as much.
