I've recommended no speakers... All I've said is that they're most like the Pro10s and therefore would be most interesting to compare with, imho... Btw, one of the Geminis have wood cabinets, so if that's your thing you can get them too... But plastic vs wood, it's not a huge deal. Like so many things in speaker design, it's mostly about compromise, so that one thing doesn't mean they won't sound good. If you've heard some of the pro monitors, some have 'plastic' cabinets and sound quite good.
Here's what they say about the C200:
THINKING INSIDE THE BOX
Anyone with a factory can build a box and stick some speakers in it (and that's just what many do). But low-frequency transducers in square boxes can create resonances that reflect off the rear wall and pass through the woofer cone out of phase, and ready to mess up your sound. The C200 enclosure is an asymmetrical monocoque design with no parallel surfaces, causing mid and high frequency resonances to be reflected at angles into internal damping materials, instead of interfering with the woofer doing its thing.
BUILT FOR SERIOUS ABUSE
Designed for use with existing speakers and power amps (and optimized for use with the Mackie PPM Series), the C200 loudspeakers are passive versions of our industry-standard SRM350 portable active loudspeakers. These speakers' injection-molded composite chassis is built for the rigors of the road. And they shrug off impacts that would turn those cheap-o, fuzz covered wood box speakers into toothpicks.
Have you heard any of these speakers? I wouldn't knock them just because they don't seem good to you, for example, because they use an injection-molded composite chassis... Again, "asymmetrical monocoque design with no parallel surfaces, causing mid and high frequency resonances to be reflected at angles into internal damping materials, instead of interfering with the woofer doing its thing."
. Does the Pro10 has that? No? Does that mean the Pro10 are an inferior speaker? No? Well there you go... They use different drivers, different horns, different cabinets, different crossovers, so crossing one out just because it doesn't use wood is a bit silly imho... Also you'd have to consider bracing, the width of the material, box design, etc...
