The American Black Walnut speakers are made in Portland, Oregon, and use the "superior acoustic properties of wood to create clear and nuanced sound," producing a 20-20,000hz frequency response with a full-range driver. The speakers have leather accents, stainless steel stands, and the carved horn shaped design of the wood boosts low frequencies without distorting them. The result? A clear and robust sound. The speakers work with phones, computers, and turntables. Plus they come with an amplifier and all the necessary cables: speaker wire, RCA to 3.5mm cable, and a power cable. $599.
