User manual BLAUPUNKT GTW 1000 MK II

[. . . ] Do not install subwoofers on loose rear shelves (fastback vehicles) or at places open to the front. Before installing the housing, 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 between the front and rear sound components of a woofer. [. . . ] Fanerskivor och plywood av god kvalitet med en tjocklek på 18 till 25 mm passar bra till lådan. Genom att fylla lådan med akustiskt dämpningsmaterial (av ull eller polyesterfiber) till minst 50 procent av den inre volymen, utökar du lådans effektiva volym med 5 till 15 procent. Please read these operating instructions before using the equipment for the first time. We provide a manufacturer guarantee for our products bought within the United States of Amerika. Com To avoid vibrations, stiffening ribs are useful for large speakers. Acoustic insulating material (sheep's wool or polyester web) which fills the inside volume to at least 50 percent increases the effective housing volume by 5 to 15 percent. The cables from the amplifier to the subwoofer should be kept as short as possible and have a cross-section of at least 2. The finished subwoofer housing should be perfectly stable and airtight. If possible, use bass reflex channels with a diameter of 7 to 10 cm to avoid the air noises generally associated with smaller openings. PVC pipes are available commercially in different diameters, whereby the pipe sections can be routed inside the housing using appropriate joints and fittings. Use active (electronic) crossovers, such as those integrated into all Blaupunkt amplifiers. Installation and installation instructions Disconnect the negative terminal of the battery before carrying out installation and connection work.
