Just got my AT8117 windscreens and thought I'd post some more info. They are serious in size, though I have still to do some tests to determine how well they work. Here's the size comparison AT8102 vs AT8117.
AT8102: 2" long, 1" diameter, mic opening, 3/8", mic insertion depth over 1"
AT8117: 3" long, 2" diameter, mic opening 5/16", mic insertion depth 2 1/2"
The foam material of the AT8102 is softer than the stiffer AT8117. The AT8117 is oval in shape vs the cylindrical shape of the DPA 0896.
The Audix 1290 fits nicely in either of the AT windscreens, but I won't know how well they attenuate wind rumble until after I do some field testing. Thought I would pass along some of my legwork to other micros owners.
Price from Full Compass is @ $7.74 (special order), B&H and SP are both higher.
