What to know before buying

Listing details to confirm

The listing is inconsistent about dimensions: one details field says 3.2"D x 3.2"W x 8.5"H, while a feature description says 8.59 inches (D) x 3.29 inches (W) x 3.29 inches (H). The same description calls for 60 watts and 360° stereo, while the title and details list 60 watts and stereo without confirming the 360° claim. IPX8 is claimed but its use conditions are not specified. The product description also mentions pairing two speakers for 120W, which is a two-speaker setup rather than a single-speaker output claim. Check the selected listing for the exact dimensions and operating conditions.

Who is it for?

A good fit for
