I had this speaker less than 4 months and it stopped working. Ill never buy this type of speaker again. I couldn't get a refund because its been over 30 days. Harmon Kardon products are usually above standard. Unable to return this speaker so I had to eat this one. A lost of $160.00

About Harman Kardon

At the start, engineer Sidney Harman and his boss, Bernard Kardon, were innovators in public-address sound systems. But the company they worked for wasn’t as interested in broadening its horizons and crafting sound systems for homes. So they created their own company, being among the first to offer a simplified receiver for radio signals with high-fidelity reproduction. That model, the Festival D1000, was a huge hit with music lovers, and in the decades since the company hasn’t looked back. Today, it produces an entire range of home audio equipment, including home-theater systems, sound bars, headphones, and Bluetooth speakers.
