The miniDSP runs a set of big (6.5 cubic foot sealed) speakers with 15" drivers, 6" mids and ribbon tweets that are suspended from the ceiling. All drivers are high efficient 94+ db sensitivity. The room is a 16x20 with 11' ceilings with the mains on the 16' wall, no room treatments to speak of (yet) but plenty of books on the walls. There is a sealed 15" home built sub under the left speaker and a small 10" Sony sub in the corner under a built in desk 20' away on the long access of the room. As it is a workspace full of equipment I don't have many (any) options on speaker or sub placement so I have to work with what I can. The speakers are hung equal distances 16" from sidewalls and 25" from the back wall, 7' from the floor, 10" to ceiling and are 6' 10" apart from one another. They are angled down and toed in to the listening space. There is precious little on the net about flying speakers for home audio, plenty for event sound reinforcement and stage work though but little of it translates to high fidelity listening environments.
As I said though, it's a work in progress and incomplete build. Things move slow in the winter here so I'm not inclined to be in the woodshop and build new boxes and baffles when it's 30 degrees out so these new mids and tweets I'm auditioning are in crude little "satellites" flying off the main boxes. Ugly as sin and hardly ideal so when I measured them for tweaking I was pleasantly surprised despite the 10dB peak to peak variations. A lot of it will get ironed out with proper boxes so I haven't dug in deep with too much analysis beyond these frequency response measurements and a glance at the waterfalls until I finish the complete build. The room problems have been consistent from many measurements over the years. They sound amazingly good though as is. A picture or two is worth a 1000 words so:
Edit: The measurement from the post above is the average taken from 17 mic positions around the room from which I created separate EQ for the left and right channels in REW. The "sweet spot" measurement has 5dB peak to peak variations and quite a bit better even at 1/12th smoothing but the room modes are still apparent (and exceed that +/- 5dB).
