Adastra KS660 In-wall Speaker 6.5" 60W
KS660 has been designed to provide premium quality room sound from within a recessed fixture. Powered by a long excursion glass-aramid woofer and a titanium dome tweeter with a custom 2-way crossover, the output is powerful yet balanced with a deep bass response that belies its size. High frequency response can be adjusted using a switch next to the tweeter to add a 3dB boost or cut to the tweeter for extra clarity or smoother tone as required. Mounting the frame into a wall or ceiling cavity takes advantage of the building and negates the need for bulky cabinets or wall brackets. For background music, home theatres, and public indoor spaces, these in-wall units deliver their sound with the detail and clarity of larger speaker cabinets in an uncluttered and discreet installation.
This is a practical option if you need a low impedance with clearly specified features and straightforward compatibility. The details below come from AVSL's current product information, so you can check the connections, size and performance before ordering.
