Grace ★★★★★

Installed these in the boat and the resin treated cloth surround really handles the humidity without any issue. Clear highs from the dome tweeter cut through wind noise nicely.

Olivia A. ★★★★★

These have been blasting on the lake all summer and the 6x9 polypropylene cones still sound crisp with zero distortion at high volume. The dome tweeters really cut through wind noise, which I didn't expect from a marine speaker at this price.

Thomas ★★★★★

Swapped out my old boat speakers for these and the difference on the water is night and day — the 6x9 polypropylene cone pushes way more low end than I expected. Even at cruising speed with wind noise, everything stays crisp.
