Adam Audio Sub 10 Mk2

The 10-inch, 200 W subwoofer that partners naturally with A7V-class monitors. Front-firing driver, variable crossover with stereo through, and a wireless remote for level — adjust from the listening position instead of crawling behind the desk.

Add it when your mixes depend on the octave below the mains' reach: electronic music, film work, translation checks for club systems. It has enough headroom that it never sounds like it's trying.

One caution: in a small untreated room, a sub this size creates more problems than it solves. Treat the room first, then buy the low end.
