It is plenty of power for mids and tweets. This notion that all speakers must be powered at or over their rms is getting silly. There are loads of tweeters that are not meant to even take 35 watts let alone 50. To add to that the Orion's tend to be under ratted by a little. Active is a little more work and harder to dial in, but the end result is superior.going active with that amp would only give each channel 50 watts and thats not enough for the rsd's....may work tho
