  • Rated 4 out of 5 stars

    smallest outdoor speaker i could find

    size and sound are both great, blends in pretty well under the eaves.

    Outdoor speakers

    The speakers sound great! Was not impressed with the mounting brackets that were included. You can purchase better brackets but feel they should be included, not an extra purchase

    Not worth the price

    I found these on sale, as a display model (open box). I was in love with the price for Martin Logan speakers that worked for my patio and a small form factor. Well they sounded awful. No mids or lows. I guess it’s not possible when the driver is 4” with a 1” tweeter. Had to return for a bigger speaker, with a larger driver.
