3. Nastavení a instalace

Správná instalace je klíčová pro výkon a dlouhou životnost vašeho subwooferu. Důrazně doporučujeme, aby instalaci provedl kvalifikovaný odborník.

3.1 Výběr krytu

The WDX8G2.4 is optimized for high-output vented (ported) enclosures but can also be used effectively in sealed enclosures. The choice of enclosure will depend on your desired bass characteristics and available space. Consult with an audio professional for optimal enclosure design and volume.

3.2 Montážní rozměry

• Montážní hloubka: 6.3 palců (16.0 cm)
• Průměr výřezu: 7.32 palců (18.6 cm)
• Vnější průměr: 8.78 palců (22.3 cm)

Ensure the mounting surface is rigid and free from obstructions. Use appropriate tools for cutting the mounting hole to the specified diameter.

3.3 Wiring the Dual 4-Ohm Voice Coils

The WDX8G2.4 features dual 4-ohm voice coils, offering flexibility in wiring configurations to match your amppožadavky na impedanci zhášeče.

• Paralelní zapojení (2 ohmy): Connect the positive terminals of both voice coils together, and the negative terminals of both voice coils together. Then connect these combined positive and negative terminals to the amplifier. This configuration results in a 2-ohm load.
• Sériové zapojení (8 ohmů): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then connect the remaining free positive and negative terminals to the amplifier. This configuration results in an 8-ohm load.

Vždy se ujistěte, že vaše amplifier is stable at the chosen impedance. Use high-quality, large-gauge speaker wire for all connections to minimize power loss and ensure optimal performance. Secure all connections firmly using the compression speaker terminals.

4. Návod k obsluze

Once installed, proper operation of your subwoofer involves careful adjustment of your amplifier and head unit settings.

• Nastavení zesílení: Nastavte ampsprávně nastavte zesílení lifieru tak, aby odpovídalo výstupní hlasitostitage of your head unit. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly. Never use the gain control as a volume knob.
• Nízkopropustný filtr (LPF): Use the low-pass filter on your amplifier or head unit to ensure the subwoofer only reproduces low frequencies. A typical setting for an 8-inch subwoofer might be between 80 Hz and 120 Hz, but this can vary based on your full-range speakers and personal preference.
• Podzvukový filtr: Pokud váš amplifier has a subsonic filter, enable it and set it just below the tuning frequency of your ported enclosure (if applicable) to protect the subwoofer from over-excursion at very low frequencies.
• Zesílení basů: Use bass boost sparingly, if at all. Excessive bass boost can lead to distortion and potential damage to the subwoofer.
• Doba záběhu: Předtím, než subwoofer otestujete na maximum, nechte jej zaběhnout přibližně 20–30 hodin středně silného poslechu. To umožní, aby se komponenty zavěšení uvolnily a fungovaly optimálně.

5. Údržba
