I agree with wid and NH.
For the price of the Studios, the M50s or M60s are worth listening to.
The M60s will have a greater midrange clarity based on what i've heard with the M40s, but both are excellent speakers.
You might want to consider going to a full tower since your room is rather large, unless of course you plan on enjoying the sound in a smaller area, say only a 12x14 area in front of the setup (approximately).
