Does anybody have an idea on dimensions of a room where the studios would not do well medium/larger size rooms?
I know the studios are made for near field/smaller room applications
I just want to get an idea of what i may expect once my family outgrows our current house and need more space.
It really depends what you want out of them. They may have acceptable bass in a very small room but in large rooms they will need subs to fill out the low end. As room size increases the power and dynamics will diminish somewhat. Larger speakers with more or larger drivers will energize a larger room much better. Its just physics, move more air. However if you can resist the urge to spread the speakers and listening position further apart in a large room, in other words keep a more near field set you will still be fine as long as you have subs, and keep the speakers out from the walls somewhat. But like always it will require experimenting with placement and setup. You can still get great imaging and sound stage performance in a large room you just may lose some dynamics and punch. This applies to all small speakers really. Of course by the time you move you maybe ready to move to larger speakers.
I'm about to find out first hand myself. I will be comparing the NX Studios I'm building to my open baffle Emerald Physics EP 2.7's (compression tweeter, 12 inch mid, two 15 inch woofers per side) very soon in a medium size room with cathedral ceiling. I will report on my findings in a couple weeks with any luck. Should be fun!
