Basically any speaker system that has flat response across the same range you'll be using the room for. In other words, if you record all types of music, from classical to extreme heavy metal, then a speaker system that covers the full 20 Hz to 20 kHz. It probably doesn't need to be so broad for most home studios, and there are quite a few good speakers that cover from, say, 45 Hz. on up. As long as the response of the speaker system you use is flat across the range that you are interested in for the final room, that'll work.You mention a 'full-range' speaker for the testing via REW; is there any particular 'cal speaker' you'd recommend for the tests
