My family were the original owners of these speakers. We actually had the entire Energy Encore 5.1 surround set, minus the integrated stands. Slowly, the rear speakers were sold. I kept the subwoofer to use with my sound bar, and the center channel broke. All that remained were these little guys sitting on the same shelving unit for the past 15ish years. I used them for a bit for my computer setup but, opted to use my Mirage Omni 350 instead.
While these are considered "big box store" speakers, they are still great little speakers. These were made in Canada. Used their hyperdome aluminum tweeter that made Energy famous from the Pro22 days (thank you Burhoe!). A super nice black piano finish and sealed box, with a 4" long throw woofer.

With the right amplification, I used a nice Crown D60, they sound pretty good for their size. I think they are better than the Realistic/RadioShack Minimus 7, and their Canadian to boot!
They are no bass monsters but, they have a very nice mid and lovely airy highs. Very clean and transparent sounding.
