User manual DLS BRXBASCL

[. . . ] Lådan limmas i fogarna och skruvas var 10 cm. Till DLS CLASSIC basar passar både sluten, portad låda och de flesta typer av bandpasslådor. Den slutna lådan kallas även tryckkammarlåda och fungerar bra om du vill ha en tight bas med bra konkontroll. Den slutna lådan är dock inte lika effektiv och ger ca 3 dB lägre ljudtryck än en portad låda. [. . . ] På samtliga DLS och GENESIS slutsteg är subsonicfilter (highpass) inbyggt. För råd om inkoppling på andra sätt än ovan, eller med fler än 1 bas, tag kontakt med din återförsäljare eller ring oss på DLS så hjälper vi till.

This manual will advice you in your installation. A correct installation is important to achieve the best possible sound from your speakers. The speakers are mainly designed for box mounting. When mounting the speakers "open air" the power handling capacity is reduced with 30% from the nominal value. Use high class speaker wires, min 2. 5 mm2. For example DLS SC 2x 2, 5. MOUNTING: IN THE HAT RACK OR BEHIND THE REAR SEAT. To avoid rattle use a baffle of MDF or particle board, min 19 mm, for speaker mounting. Attach screws to all screw holes and tighten them even to avoid the speaker basket to get inclined. CONNECTION: + Connected with a 6 dB passive low-pass x-over = 6, 3 mH coil in series. X-over frequency 100 Hz. BOX MOUNTING: A speaker box is normally made of MDF or particle board, min 19 mm. Use sealing compound in all joints and at the cable entry. Both sealed, vented and most types of bandpass boxes are suitable for DLS CLASSIC subwoofers. The sealed box is good for hard rock and disco music and gives a good control of the cone. The vented box is more efficient and gives a 3 dB higher level than the sealed type. In small vented boxes the ports can become rather long. You can angle the port inside the box or mount it out from the box, for example when the ports are mounted through the hat rack. There must be a free space of at least the port diameter behind the port opening inside the box. Use ports with conical openings to avoid noise at low frequencies caused by air turbulence at the port edge. + - Connected with a 12 dB passive low-pass x-over = 10 mH coil in series and a bipolar capacitor of 300 µF in parallel. X-over frequency 95 Hz. Active filter DIRECTION OF THE BOX: In a SEDAN-type car the best result is achieved when the box with both speaker and port is directed towards the rear seat. The port should not be directed up Mono bridge mode with an active low-pass filter before the through the hat rack if the speaker is directed towards amplifier. [. . . ] Most suitable for hard rock and disco type music.
