Subwoofers under $2,000 have the driver size, amplifier power, and enclosure engineering to handle larger rooms and more demanding material without strain. Drivers are 12 inches or larger with long-throw excursion for deep extension. Built-in amplifiers deliver enough clean wattage to pressurize a room on sustained low-frequency passages, not just momentary peaks. Room correction at this price goes beyond basic level matching to address phase alignment and room modes that cause uneven bass response at your listening position. That last part matters more than most people think.
