The design features of subwoofer cabinet mainly include structural type, sound effect, manufacturing materials and debugging methods.
Structural type
Subwoofer cabinets mainly have the following design types:
Enclosed speaker cabinet: This kind of speaker cabinet is completely enclosed, with simple structure, good transient response, deep and clear listening, but the low-frequency dive cutoff frequency is high, usually requiring a larger cabinet volume and a larger speaker unit.
Phase-inverted speaker: This kind of speaker uses a phase-inverted tube or phase-inverted hole to enhance the bass effect, which can provide deeper low-frequency dive and greater sound pressure level, and is suitable for use in smaller spaces.
Bandpass filter speaker: This design uses a bandpass filter to enhance the bass effect in a specific frequency range, and is suitable for occasions that require a specific frequency response.
Sound effect
The design of the subwoofer cabinet directly affects its sound effect:
Deep and clear: The sealed speaker has a simple structure, good transient response, and a deep and clear listening experience.
Low-frequency diving depth: The bass reflex speaker enhances the bass effect through the bass reflex tube or the bass reflex hole, providing deeper bass diving and greater sound pressure level.
Specific frequency enhancement: The bandpass filter speaker enhances the bass effect of a specific frequency range through a bandpass filter, which is suitable for occasions that require a specific frequency response.
Manufacturing materials and debugging methods
The manufacturing materials and debugging methods also have an important impact on the performance of the subwoofer box:
Making materials: Commonly used manufacturing materials include wood materials such as MDF (medium-density fiberboard) and particle board, which have good sound absorption and vibration isolation properties.
Debugging methods: During the manufacturing and debugging process, it is usually necessary to fill the box with sound-absorbing cotton, such as glass fiber or long-fiber wool, to improve the flexibility and efficiency of the speaker. The correct filling amount can be determined by repeated audition to achieve the best sound effect.
