I have been researching LFE crossover settings and I am not sure whether I should pick 60Hz or 80Hz for my setup. I am fairly certain that I should be setting all 5 of my speakers to "SMALL." I realize it is more complicated than just the ratings on my speakers but these stats are a good place to start.
The lower extension (+-3dB) on my speakers are:
VR3 mains - 35Hz
VRC center - 70Hz
VRX surrounds - 80Hz
Cheap subwoofer (for now) - 25Hz
Setting the LFE crossover at 60Hz will help to diffuse the somewhat directional 60-80Hz frequencies by letting my mains take care of that range. This would also relieve my subwoofer of another 20Hz. As far as I am aware, the only downside that comes with the 60Hz crossover is the fact that my center and surrounds are only able to reproduce frequencies down to 70Hz and 80Hz, respectively. Due to this fact, how badly do you think the dynamic range / clarity of these channels will be affected by feeding them 60-80Hz frequencies?
Setting the crossover at 80Hz would avoid this issue, however, I am a bit concerned about the 60-80Hz range coming only from the subwoofer. I read that the 60-80Hz range is only directional to the human ear when the source is within a close proximity to the listening space. I am not sure how far away the subwoofer has to be before that range would be safe to send to the subwoofer alone. In my theater the subwoofer is about 11-12 feet away from the primary listening positions. Do you think this is far enough away to warrant an 80Hz crossover setting?
