this is to physically compare two fairly popular shallow 8" midbasses.
c8 specs - http://illusionaudio-america.com/downloads/CarbonC8.pdf
w800neo specs - http://www.audio-development.eu/uplo...O_INGL_web.doc
you can see the c8's mounting flange is a bit larger than the w800neo.
laying the w800neo on top of the c8, you can see the outer diameter of the w800neo is smaller than the c8.
however, inside of the flange and outer part of the surround are about the same size, indicating the surrounds and cones are about the same size:
magnet structure of the c8 sticks out a bit, but the overall frame for both drivers have a similar shape. however the w800neo has the full magnet structure behind the cone.
offsetting the c8's magnet, they've both got a very similar depth, sans terminals.
the w800neo's terminals stick out quite a bit more than the c8's terminals. both can be replaced with bolts, nuts, and ring terminals to minimize depth.
