Pros: A 12 inch ported subwoofer with output close to far bigger flagships, a strong used pick now that it is discontinued. 12-inch ported driver reaches 130.2dB CEA-2010-A average, nearly matching the class leader for about $1,000 less.

Cons: Ported design room interaction, 45 kg size, and $2995 cost. Discontinued.

Notes: Looks like “PA sub”
