Generally speaking, the materials required for water resistance make sonics tricky. Speaqua has somehow circumvented those limitations to good effect.Sure, the top-end isn’t quite as sparkly as bookshelf speakers, but it’s not bad. The mid-range is reasonably well-defined, and there’s bass. Not tons of it, but even sub-bass was rendered at times, though it tended to fade more quickly than the actual signal. Apparently it’s a marginal thing.As mentioned, the Barnacle X has two audio modes: indoor and outdoor. I didn’t have a users guide for my testing, so I don’t actually know which mode is which. But when it flashes pink/purple there’s more bass with a slightly scooped mid-range, and when the RGB flashes blue, there’s less bass with more pronounced mids and highs.
