{"product_id":"adastra-bp4v-b-100v-4-weatherproof-background-speaker","title":"Adastra BP4V-B 100V 4\" Weatherproof Background Speaker","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003eThe Adastra BP4V-B is a weatherproof 4-inch background speaker built for 100V line systems, and it's a water-resistant version of the well-regarded BC series PA speakers. The main driver uses a water-resistant polypropylene (PP) cone, while the tweeter has a polymer diaphragm, both chosen to keep working reliably in humid and outdoor conditions. It's supplied singly in black, so you can buy exactly the number you need for a given install.\u003c\/p\u003e\n\u003cp\u003eThe cabinet is a moulded ABS enclosure fitted with a powder-coated aluminium grille, giving an IP54 weatherproof rating. Connection from your amplifier is through a hard-wired 1m lead, which keeps the IP protection intact all the way back to a junction box or indoor area. A rotary selector switch lets you set the 100V line tapping, or run the speaker at 8 Ohms if you'd prefer low-impedance operation. That makes it easy to balance output across several speakers on the same 100V line.\u003c\/p\u003e\n\u003cp\u003eMounting is straightforward. A wall mounting bracket is supplied, and there are alternative M6 threaded points if you'd rather fix it another way. The operating temperature range runs from -5°C to +40°C, so it copes with covered outdoor areas, garden bars, patios and similar spots that see damp and cold. If you need clear, even background sound across a wider range of environments than a standard indoor speaker can handle, the BP4V-B is a sensible choice.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.63KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e150mm x 195mm x 150mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTappings\u003c\/td\u003e\n\u003ctd\u003e20W, 10W, 5W, 2.5W + 8 Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImpedance : 100V\u003c\/td\u003e\n\u003ctd\u003e500, 1k, 2k, 4k Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSPL @ 1W\/1m\u003c\/td\u003e\n\u003ctd\u003e88dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower rms : 8 Ohms\u003c\/td\u003e\n\u003ctd\u003e35W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower max. : 8 Ohms\u003c\/td\u003e\n\u003ctd\u003e70W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003e110Hz - 20kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTweeter\u003c\/td\u003e\n\u003ctd\u003e25mm (1'') balanced dome\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWoofer\u003c\/td\u003e\n\u003ctd\u003e100mmØ (4'') polypropylene cone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eMoulded PP cabinet with aluminium grille\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP rating\u003c\/td\u003e\n\u003ctd\u003eIP54\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating temperature range\u003c\/td\u003e\n\u003ctd\u003e-5°C to +40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection\u003c\/td\u003e\n\u003ctd\u003e1m hard-wired speaker cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/952813UK_1d6af554-15ad-493e-a792-377c0a1733ec.pdf?v=1785056061\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use the BP4V-B at 8 Ohms instead of 100V?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
