Hey, Z-man, Rob and others with BassBox Pro or similar. I could use some help sizing a box for a single E110 to take full (or nearly full) advantage of its lower frequency limit--its FAR is about 55. Use will be for keyboard, guitar and voice.

I'm also exploring using four of them in a single omni-directional enclosure. The drivers would be facing in the four directions with a slight upward tilt to their axes. I know the 4680 was about 5 cu. ft., but don't know what the porting was. Anybody have a notion what acoustic coupling would do with such a configuration?

Thanks,

David
