I used this speaker to replace a blown one in a small guitar amp. It sounds awesome! It sounds way better than the original, when it was new. The lows boom instaed of flap and the highs sound clear and full.The price on Overstock was lower than anywhere else and I received the speaker promptly.In terms of ease of operation, I did need to change the housing to fit the speaker, but it was a minor change. There is not much to say abou the features, it has two leads to connedt to, pretty simple. Overall this was a great find and purchase.
