Choosing the right subwoofer depends on your room, main speakers, listening habits and whether the system is primarily used for music, home cinema or both. Driver size and amplifier power are useful specifications, but they should not be considered in isolation.
Room size
Room size has a major influence on subwoofer choice. Smaller rooms generally require less acoustic output and can often achieve excellent low-frequency extension with a compact subwoofer. Larger rooms require greater output capability and usually benefit from larger or more powerful designs.
Choosing a subwoofer with sufficient headroom is important, but bigger is not automatically better. The goal is controlled, effortless bass that integrates naturally with the main speakers and the room.
Music or home cinema
Different subwoofers can be optimised for different priorities. Music-focused designs place particular emphasis on speed, control and seamless integration with stereo speakers, while home cinema-focused models prioritise deep extension, dynamics and high output for demanding low-frequency effects.
Many subwoofers are designed to perform equally well with music and movies. Our Recommended use filter distinguishes these versatile models from products with a more specialised focus.
Integration with your speakers
A well-integrated subwoofer should not draw attention to itself. Crossover frequency, level, phase and positioning all influence how naturally it blends with the main speakers.
Compact bookshelf speakers may benefit from a higher crossover frequency, while larger speakers can usually be crossed over lower. Systems with advanced bass management or room correction can offer additional flexibility when integrating one or more subwoofers.
One or more subwoofers
A second subwoofer is not only about achieving more output. In many rooms, using two properly positioned subwoofers can produce a more even bass response across the listening area and improve consistency between different seats.
The optimum solution therefore depends on the room and system rather than simply on the maximum output of a single subwoofer.
Finding the right match
Use the Recommended room size and Recommended use filters to narrow the selection. These recommendations are practical starting points rather than absolute rules, as room acoustics, placement, listening level and integration with the main speakers all influence the final result.
