Adastra AB-5 Bookshelf Speakers 4 Ohm - Pair
A pair of passive low impedance bookshelf speaker cabinets finished in black woodgrain vinyl with M6 mounting points at the rear. Each speaker provides maximum power conversion with most stereo amplifiers which can operate down to 4 Ohms, and is fitted with a 5.25" main driver and a 1" silk dome tweeter for balanced, full range output. A perfect match for Adastra and other low impedance amplifiers for background music, radio and voice announcements.
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.
