{"product_id":"adastra-ks660-6-5-60w-in-wall-speaker","title":"Adastra KS660 6.5\" 60W In-wall Speaker","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003eThe Adastra KS660 is a 6.5-inch in-wall speaker built to give you good room sound from within a recessed fixture. It pairs a long excursion glass-aramid woofer with a titanium dome tweeter, working through a custom 2-way crossover. The result is a powerful yet balanced output with a deeper bass response than you might expect from a driver this size. Because the frame mounts straight into a wall or ceiling cavity, you use the building itself as the enclosure and avoid bulky cabinets or wall brackets.\u003c\/p\u003e\n\u003cp\u003eHigh frequency response can be tuned with a switch next to the tweeter, which adds a 3dB boost or cut. Use the boost for extra clarity or the cut for a smoother tone, depending on the room and the material you play. Power handling is rated at 60W RMS and 120W maximum, with an 8 Ohm impedance and sensitivity of 89dB at 1W\/1m. The frequency response runs from 45Hz to 20kHz, so you get useful low end alongside clear treble.\u003c\/p\u003e\n\u003cp\u003eInstallation is handled by six dog-ear clamps that grip the wall or ceiling board, and a frameless magnetic grille (grill in US English) that sits flush for a clean finish. Durable spring contacts make wiring straightforward. At 320 x 220 x 102mm and 2.20kg each, the KS660 suits background music, home theatres (home cinemas), and public indoor spaces where you want the detail of a larger cabinet without the clutter. It gives you a discreet result that keeps the focus on the sound rather than the hardware.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower handling : rms\u003c\/td\u003e\n\u003ctd\u003e60W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower handling : max\u003c\/td\u003e\n\u003ctd\u003e120W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLF driver\u003c\/td\u003e\n\u003ctd\u003e165mmØ (6.5”) Glass Aramid Woofer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHF driver\u003c\/td\u003e\n\u003ctd\u003e25mmØ (1”) Ti Dome Tweeter\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\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003e45Hz - 20kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity @ 1W\/1m\u003c\/td\u003e\n\u003ctd\u003e89dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e320mm x 220mm x 102mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e2.20KG\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\u003eWhat size is the KS660 woofer?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe main low frequency driver is a 165mm (6.5 inch) glass-aramid woofer, paired with a 25mm (1 inch) titanium dome tweeter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much power does it handle?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePower handling is 60W RMS and 120W maximum, with an impedance of 8 Ohms.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I adjust the treble?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
