You are looking for speakers for DJing and you have a 600 Watt amp. What kind of speakers do you buy?

With 600 watts, you can't really go too big, and if you only have one amp, you can't go with separate mids/highs and a sub, so personally, I would try to find a pair of 200 watt speakers that have nice tweeters, mids, and lows, all in one. Don't go for anything over 200 watts each, because you want to leave room on your amp. You don't want to get two 300 watt speakers, because your amp will be working at full power, which isn't good for it or your new speakers. So all in all, a nice pair of 200 watt full range speakers is what I would be looking for.
