Notes about installing a subwoofer in enclosure:
Before installing the subwoofer in an enclosure guidelines, please observe some fundamental design instructions:
- Subwoofers with infinite baffle can be installed in a vehicle by simply using a wooden board trimmed to size which ensures an acoustic separation bet ween the front and rear of a woofer. The wooden board is affixed in the boot under the rear shelf or at the back of the rear seat bench. Any existing air gaps should be sealed with sealing material .
- The shape of the enclosure plays a major role with respect to the playback of low frequencies. However, try to avoid unusual shapes which require extensive work with respect to trimming and gluing .
- MDF boards or high-quality ply wood made out of birch with a thickness of 18 to 25mm are perfectly suited for building woofer enclosures .
- All abutting housing walls should be glued, screwed together and sealed to a void detachment due to vibration & external environmental influences in a vehicle
- To avoid vibration, stiffening ribs or bracing are used for large woofer enclosures .
- Acoustic insulating material which fills the inside volume to at least 20% increases the effective enclosure volume by 5 to 15%.
- The cables from the amplifier to the subwoofer should be kept as short as possible & have a cross 2 section of at least 2.5mm .
- The finished subwoofer enclosure should be perfectly stable and airtight.
- If possible, use bass reflex ports with a diameter of 7to 10cm to avoid the port noise generally associated with smaller openings. PVC pipes are available commercially in different diameters. The pipe sections can be installed inside the enclosure using appropriate joints and fittings.
- Use an active (electronic) crossover, such as those integrated into all Blaupunkt amplifiers. The use of passive crossovers is not recommended.
