The choice of subwoofer box structure depends on the specific usage scenario and needs. The following are the characteristics of several common box structures and their applicable scenarios:
1. Enclosed box
Features: The box is completely enclosed, the structure is simple, the transient response is good, and the sound is clear and deep.
Advantages: The low-frequency performance is accurate, suitable for music lovers with high requirements for sound quality.
Disadvantages: The low-frequency dive frequency is high, requiring a larger box volume and a larger caliber speaker unit.
Applicable scenarios: Hi-Fi system, music playback that pursues pure sound quality.
2. Phase-inverted (port-type) box
Features: The low-frequency diffusion and extension are enhanced through the phase-inverted tube design, and the low-frequency performance is stronger.
Advantages: The low-frequency dive is deeper, suitable for high-volume playback and home theater scenes.
Disadvantages: The transient response is slightly weak, which may affect the clarity of the music.
Applicable scenarios: Home theater, movie playback that pursues shocking sound effects.
3. Labyrinth cabinet
Features: The complex internal structure prolongs the sound wave path and enhances the low-frequency effect.
Advantages: Excellent low-frequency performance, suitable for mid-to-high-end audio systems.
Disadvantages: Complex technology and high cost.
Applicable scenarios: Mid-to-high-end car audio systems.
4. Bandpass filter cabinet
Features: Combining the characteristics of closed and inverted types, the low-frequency output is optimized through a bandpass filter.
Advantages: Balanced low-frequency performance, suitable for a variety of scenarios.
Disadvantages: Complex design and high debugging difficulty.
Applicable scenarios: Multi-functional audio system.
Summary
Music lovers: Give priority to closed cabinets to obtain purer sound quality.
Home theater users: Inverted cabinets are more suitable and can provide more shocking low-frequency effects.
Mid-to-high-end car audio: Labyrinth cabinets are a good choice, but the cost needs to be considered.
Multi-function requirements: Bandpass filter cabinets provide balanced performance, but require professional tuning.
When choosing, you also need to consider factors such as room size, playback content, and budget.
