Well two months on and wondering how these are working out.
Interesting little speaker.
Well, since they sit on my desk, I guess I'm best qualified to answer
My impressions now are much like I posted earlier. Ideally, they'd be positioned closer to ear level.
I did a little modification that seems to help my particular situation, but I can't speak as to why. I stood a CD case behind the upper woofer. I'm sure it introduces some reflection, but it gets them closer to the way they sound when my ears are in line with the top. I imagine I'm breaking some basic rule of speaker design, but the audio police haven't shown up, so life is good.
Don't get me wrong, they accomplished the goal, but I would be wrong to gush about their giant killer ability. I'm certain they perform better than any computer speakers I've heard. All in life is some kind of compromise, no? They would be better served in a bigger space, meaning less nearfield, but it is a desk after all.
Aside from the sound, I am really pleased with the way they look. Even cooler when paired with the reskinned receiver I posted about. So much do I like the crisp, contemporary style, that my next project will have the same look with a little twist...stay tuned.
If I were to build them again and had a little more space to work with, I might rotate them 90 degrees and center the drivers on wide side. I also think a rear mounted tweeter could add some sparkle, as Danny suggested.
Total dollar investment of around $100, I feel like I got more than my money's worth. I should add, though, that I already had the receiver and sub, so if starting from scratch that would be more.
