Rated 2 out of 5 by from Speaker purchaseThis is the second purchase of speakers that I am trying to replacement my existing towers. Neither of thjem fit. I was looking for a 4.5" nominal diameter and the description said so, but it was not 4.5".

Rated 4 out of 5 by from Top Notch For The CostThere is only one thing I wish this sub had and that is a little more punch to it. Over all I have to say this speaker is a great deal for anyone who is looking to replace a blown speaker or who just wants a good sounding inexspensive speaker.

Rated 4 out of 5 by from Decent Replacement for my BMWInstalled in the back of my 328 convertible. Didn't have the bass of stock speakers, but I was adding a sub so it didn't matter, worked great in the midrange.

Rated 3 out of 5 by from Good ValueI replaced the subwoofer driver in a Altec Lancing 3pc computer speaker set. This speaker works and fits well in the waveguide enclosure but doesn't have the same "punch" as before. But overall it's an excelent value!
