Studioproject, below is the graph of an M60 with an EP500. The EP600 would add another 4 Hz to the low end response going flat down to 16Hz. This is an excellent combination for studio use if you can live with the size of the M60s. If the size is just too large then I would suggest the M22 instead with either an EP500 or even an EP600. A subwoofer cable of reproducing the very low frequencies of the EP500 and EP600 will ensure that you know what is going on way down there in your final recording.
The distinction between pro and hi-fi speakers for studio use has really nothing to do with performance. The usual difference is the pro studio speakers tend to have built in amplifiers for ease of connection to the board. The key to proper monitors is mainly linearity. Any colouration in the speaker will affect the mix in a detrimental fashion. Certainly the items mentioned in the article you posted re compression are also factors but there is no reason to think that compression is any less likely to occur in a pro speaker versus a hi-fi speaker. It really comes down to good speakers versus bad ones no matter their classification. Coincidently enough I measured some KRKs when we were setting up one of Aldo’s studios and they were appalling. The colouration was so bad that they were hard to listen to; this would certainly make for some poor end results in the recording. Hope all this helps you out.
