I'd like a pair of high quality (good sounding) small speakers to be used as desktop monitors. Something with 5 to 6.5 woofers, but not too big physically. My current set of monitor speakers are $30 5" woofer/poly tweeter cheapies. The lowest quality stuff purchased in a rush when my other ones lost tweeters. I've had to go crazy with the equalizer to make these sound OK. I'm powering them by an external amp w/sub. But I could use powered speakers too, if they sound awesome. Thinking of a set of Polk speakers to match my home system. Thoughts?
