Its IP66 protection applies to the front when it is built into a sealed enclosure. This white 4 Ω version handles 20 W, gives 85 dB (1 W\/1 m) and is rated for −40 to 80 °C.\u003c\/p\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOutdoor PA systems\u003c\/li\u003e\n\u003cli\u003eSolariums and damp rooms\u003c\/li\u003e\n\u003cli\u003eBoats, ships and open vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKey selection facts\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNominal size: 10 cm \/ 4 inch\u003c\/li\u003e\n\u003cli\u003eImpedance: 4 Ω\u003c\/li\u003e\n\u003cli\u003eRated power: 20 W\u003c\/li\u003e\n\u003cli\u003eCut-out: 101 mm\u003c\/li\u003e\n\u003cli\u003eSensitivity: 85 dB (1 W\/1 m)\u003c\/li\u003e\n\u003cli\u003eResonance: 120 Hz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eInstallation and compatibility\u003c\/h2\u003e\n\u003cp\u003eAllow for a 101 mm panel opening. The round flange is 132 mm in diameter with four 4.5 mm fixing holes, countersunk to 8 mm, on a 120 mm circle; mark them from the unit itself rather than assuming the spacing. Behind the panel allow about 41 mm for the 100 mm basket and its 70 mm magnet cup, plus room for the terminals and the wiring; the domed grille stands about 15 mm proud of the panel, so allow for that behind any fascia or trim and keep the grille clear.\u003c\/p\u003e\n\u003cp\u003eThe IP66 protection applies to the front of the driver only, and only when it is built into a sealed enclosure; the rear is open to the enclosure. Seal the joint between the flange and the panel, for which a matching gasket, part 2112, is available, and protect the rear from water and dust; bonding the driver in and fitting a front cover or grille may be needed to complete the protection. Fit the gasket dry and tighten the fixings evenly so the flange is not distorted. Run the cable so that water cannot track along it into the enclosure, and leave a drip loop where it is exposed. Operating temperature range −40 to 80 °C.\u003c\/p\u003e\n\u003cp\u003eConnect to the 4.8 x 0.8 mm (+)\/2.8 x 0.8 mm (-) blade terminals with matching push-on connectors and observe polarity; the blades differ in width, so the wider blade identifies the positive. Use an amplifier suitable for the 4 Ω load and keep the drive within the 20 W rating (30 W maximum). For a 100 V line system, connect through a suitable line transformer; do not connect the driver directly to the line.\u003c\/p\u003e\n\u003cp\u003eThis is the white version; the black version is part 2130.
