Adept Audio IO80

Adept Audio’s surface-mount loudspeaker line up is tough-as-nails and voiced for tremendous sound in small or large outdoor installations as well as indoor.

Product Details

This speaker can champion most any custom install challenge! Need to cover a large indoor or outdoor installation? No problem!  Thanks to our front-mounted, 70-volt/4-ohm adjustable transformer tap, you can mount the IO80 and then configure it any way necessary later on, without removing it.

The IO80’s solid drivers can handle the power required for diverse out-of-doors listening scenarios. This speaker’s specially tuned slot port pumps out enough low bass to get a crowd of people dancing — with no subwoofer needed!
