There are tonnes of SEOS builds.
Here's mine...
1) Link:
BassThatHz's 7 seos12's, 7 cel-15's, 6 dayton um's, build thread
2) 7 Cheap Thrills Kits, but in custom boxes and 6 UM-15's as woofers, and a mix of active/passive circuitry with what is essentially four quad-monoblocks (33,600watts @ 4ohms into the seven).
Impressions thus far: Requires EQ to sound most-optimal but DAMN impressive for the PRICE. On par with my B&W N803's for SQ but... more efficient, much higher power handling, and louder too.
3) Temporary Pictures of work-in-progress:
Rears:
Mains:
