Add deep, powerful bass to a compatible Bose home theater system with the Bose Acoustimass 300 Wireless Bass Module in White. This premium powered subwoofer combines a powerful 10-inch driver, Bose QuietPort® technology, wireless connectivity, and an elegant tempered-glass top to deliver impactful low-frequency performance for movies, television, music, sports, and gaming.
The Acoustimass 300 was originally introduced for the Bose SoundTouch 300 soundbar and is also supported with a range of compatible newer Bose soundbars and home theater systems.
Used – Very Good
This pre-owned Bose Acoustimass 300 has been inspected and is in very good cosmetic and working condition. It may show minor signs of previous use that do not affect normal performance.
Please review all actual product photographs carefully for the exact cosmetic condition and included accessories.
No other accessories are included unless specifically shown in the actual product photographs.
The Acoustimass 300 is designed to add greater depth and impact to compatible Bose home theater systems.
Its powerful 10-inch driver enhances low-frequency effects in movies, music, sports, games, and television, providing bass performance that a soundbar alone cannot reproduce.
Bose QuietPort technology works with the bass module's ported enclosure to deliver strong low-frequency output while helping reduce unwanted distortion and port noise.
The Acoustimass 300 can connect wirelessly with compatible Bose soundbars and home theater systems for flexible placement and a cleaner installation.
If wireless interference is a concern, supported Bose systems can also use a shielded 3.5mm audio cable between the soundbar or host device and the bass module.
Bose currently provides support for using the Acoustimass 300 with compatible products including:
Some compatible Bose products may require a wired connection rather than wireless pairing. Please verify compatibility and connection method for your specific Bose system before purchasing.
For best performance, place the Acoustimass 300 on the floor along the same wall as the television and soundbar with access to an electrical outlet.
Moving the bass module closer to a wall or corner generally increases perceived bass response, while moving it farther away may reduce bass output.
This is a Used – Very Good Bose Acoustimass 300 Wireless Bass Module.
This listing includes the bass module and power cord unless additional accessories are specifically shown in the actual product photographs.
The Acoustimass 300 is an add-on bass component and is not a standalone Bluetooth or Wi-Fi speaker. It requires connection to a compatible Bose host product.
