Not taking the personally destructive nature of a room's acoustics, based on a subwoofer's placement, into consideration.....of course.
(and then, in real terms vs the ideal of a ground plane test, does one live with only ONE subwoofer in their life or do they eventually give into the darkside?)
The original, in room graphs of two RW12 II's; EQ'd with Audyssey, MultEQ XT.
The red graph is our latest in room measurement (EQ'd with Anti-Mode, 8033S II & XT) with three subwoofers (2 SW-12 with upgraded drivers and 1 RW-12d, all subs have poly-fill added) vs the blue graph, two SW-12 subwoofers with original drivers, no polyfill added. The point of the graphs is to highlight the difference of ground plane vs in room. And in this case, two similar subwoofers vs three subwoofers, two with upgraded drivers all modified with poly-fill added to the cabinets.
(room is a very active room with no added room treatments allowed)
The point, unfortunately, for comparative purposes, the equalizing ground plane test won't tell one what their room acoustics is going do to these beautiful (ideal?) ground plane graphs......enters the need to have the ability to measure one's listening venue.
