I was looking for a microsub to fit under a side table to go along with a pair of Aperion bookshelves (4b's). I came across the Energy ESW-M6 at NE for $179.99 and free shipping. I won't need a ton of deep bass as this is just a small system in our kitchen/family room and will be for music only. From what I've read this sub has good punch and the footprint is perfect. I'm also thinking about ordering another one to go in the living room as a second sub for our theater. For those looking for a 2nd sub for theater this may be perfect. Or, they have the 8" model for $279.
