2 K12’s would be OK, I use a pair of DXR 10’s as monitors and for smaller low or no paying gigs. Personally I find that 10’s and 12’s don’t tend to have much low bass. *****Boxes with 15’s do a lot better.**** So if you go with the non sub option you should really consider that. QSC K series and Yamaha DXR’s are both nice speakers imo, yamaha has a better warranty and a clearer tone imo. Don’t forget to check craigslist! If you’re in a big city you can find great deals on CL sometimes, larger production companies and event rental places replace their gear frequently for tax reasons and sell used gear at a loss, so sometimes you can get a good deal that way. BUT REALLY LOOK FOR 15’s over 12’s for dance music if you’re not gonna get a sub.
I caution against buying cheaper speaker brands for many reasons: they’re not as simple or elegantly designed, they are either really heavy or are made of really cheap materials that sound like shit, they tend not to be as reliable and don’t tolerate abuse as well. If your gear is heavy and hard to transport you’ll dread doing it, trust me I know from experience. I’ve been doing sound and logistics for over a decade and DJing nearly as long. ATM I own yamaha DXR10’s, 10 yamaha club 12’s, 2 club 218, 2 QSC GP218’s 2 B-52 ACT 1550’s, and 2 JBL MP418’s, as well as a slew amps, lighting, processing, etc. etc.
Try to get road cases or padding of some kind, I’ve seen more gear get fucked up in transport than any other way.
