I purchased these as "open-box" from Best Buy's eBay storefront, as the local BB didn't have the OB units in stock. My intent for these speakers is a little different than most folks', I imagine - I wanted to use these as external add-on speakers for my two amateur radio transceivers, since the built-in speakers on both units leave much to be desired. I didn't want to spend a lot, and while I had tried CB radio speakers, they didn't quite have the tonal quality I was looking for.
I connected the Insignias with some spare speaker wire hooked up to 1/8" stereo plug-to-screw-terminal adapters (the + side of the wire goes to the L terminal, the - side of the wire goes to the ground terminal).
Lo and behold, they work great! It's much easier to discern voices over the air that I was having trouble with before; I was concerned that the tweeter might introduce too much background hiss, but these speakers sound great. As I only needed one speaker for each radio, the set of 2 was a great value, especially as an "open-box" buy - these are just like brand new.
Just to test them, I did hook them up to my Insignia mini shelf system, and while they didn't have the fullness of the system's original speakers, they sounded pretty good - nice crisp highs and warm mids, albeit with less bass response. I can only wonder how they would do after a break-in period.
I can't comment on how they would stand up to the outdoor environment, but they are pretty solidly constructed.
All in all, if you're looking for an all-around decent-sounding utility speaker, check these out!
