I just purchased these speakers for an N1R I bought off of eBay. (I know, they're cheap, but keys aren't my main instrument.)

Each speaker (I bought a pair) has 4 jacks. 2 1/4" and 2 XLRs. The ad states "high powered crossover network" as a feature. Does this mean that a "crossover" is built in to the speakers? Sorry, I'm a total noob to this stuff.

Also from the add it looks like the specs read 400 watts PEAK and 200 watts continuous. So does this mean, in theory, that I should get a 800 - 1000 watt power amp to power these (about 450 to 500 watts per channel)?

I'm currently using a 500 watt solid state GUITAR power amp (ADA G500S), picking a jack to plug in to on the speaker (they're not labeled) and feeding one channel from the power amp to each speaker in mono. I can crank the power amp and the Korg N1R to max without getting anything close to an extreme amount of volume so I fear I might ruin my speakers and/or power amp since it's probably clipping before the speakers even get what they're asking from the power amp. I tried taking both R/L outputs from the stereo power amp into just one speaker and it didn't seem to make much difference.

What kind of power amp should I get to power these speakers? Dual stereo (if they make those)? I'd like to "think big" in regards to sound level in the case that I should choose to use this setup as a PA on occasion.
