Amazon is now offering the Marshall Kilburn II Portable Bluetooth Speaker for $199.99 shipped. Also matched at Best Buy. Regularly as much as $300 at Amazon and more like $250 at Best Buy, this is up to $100 off and at least $50 off the going rate for the lowest total we can find. Alongside the classic guitar amp stylings here, you’re looking at 20 or more hours of playback per charge with “a clear midrange, deep bass and extended highs that are unrivaled for a speaker this size.” Multi-directional sound, Bluetooth 5.0, a water-resistant design, and the ability to connect two Bluetooth audio sources at once round out the feature set. You can learn even more in our hands-on review. Rated 4+ stars from hundreds at Best Buy. More Marshall speaker deals below.
