Each speaker uses a hi-flex 5.25\" main driver for full range output with extended low frequency response, paired with a mylar tweeter that handles the high frequencies cleanly. A 2-way crossover network splits the signal between the two so each driver does its job properly.\u003c\/p\u003e\n\u003cp\u003eFitting is straightforward. The SL5 uses three 'dog-ear' mounts (the same as the SL6) that clamp the speaker against the underside of the ceiling once it is pushed into the cut-out, so you do not need access from above. Wiring is handled by gold-plated spring terminals, which grip bare speaker cable and resist corrosion over time. The flared baffle helps spread the sound across a wide area, with a dispersion angle of 160 degrees, so you get even coverage across a room rather than a narrow beam.\u003c\/p\u003e\n\u003cp\u003eWith an 8 ohm impedance, the SL5 works with standard hi-fi amplifiers and most multi-room amps, making it a sensible choice for kitchens, bathrooms, hallways and general background listening. The low profile sits close to flush with the ceiling once painted or left as supplied, keeping the room clean and uncluttered. As part of the wider SL range, the SL5 lets you match speaker sizes across different rooms while keeping a consistent look throughout.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (each)\u003c\/td\u003e\n\u003ctd\u003e1.30KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (each)\u003c\/td\u003e\n\u003ctd\u003e93mm x 203mmØ\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\u003eMounting depth\u003c\/td\u003e\n\u003ctd\u003e93mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCutout\u003c\/td\u003e\n\u003ctd\u003e178mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower rms\u003c\/td\u003e\n\u003ctd\u003e35W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003e50Hz - 20kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrossover frequency\u003c\/td\u003e\n\u003ctd\u003e4.5kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTweeter\u003c\/td\u003e\n\u003ctd\u003e12mmØ  (0.5\") mylar dome\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWoofer\u003c\/td\u003e\n\u003ctd\u003e130mmØ (5.25\") PP cone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImpedance\u003c\/td\u003e\n\u003ctd\u003e8 Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDispersion angle\u003c\/td\u003e\n\u003ctd\u003e160°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eAre the Adastra SL5 speakers sold individually or as a pair?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThey are supplied in pairs, so one order gives you two matching ceiling speakers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat amplifier do I need for the SL5?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe SL5 has an 8 ohm impedance, so it works with standard hi-fi amplifiers and most multi-room amps.
