As of 2015, subwoofers for home stereo systems typically cost between $100 and $500, with high end models costing as much as $2,000 or more. Automobile subwoofers range from as little as $15 to more than $1,000, with mid-range models generally costing between $50 and $300.
The subwoofer size plays a significant role in the price, with most home models falling between 6 and 12 inches in diameter. Differences in wattage and decibel range also greatly affect the cost.
Many auto subwoofers come bundled with installation kits that also include amplifiers and other equipment. Likewise, home subwoofers packaged with speakers often cost less than stand-alone models.
