As far as I knew, these have been off the market for some time.
Maybe they found some hidden in the back section of a warehouse somewhere?
RC-10 bookshelf
Crank it to eleven for your own Spinal Tap reunion tour right from your own living room and you'll swear you're listening to speakers twice as large. Space at a premium?. Try the RC–10…they're big in sound only.

RC-LCR Center (and L&R)
The RC-LCR-it works like magic. Place it upright and it rocks out as a left or right front speaker for music. What’s the secret?. An Energy exclusive diagonal tweeter/midrange design that disperses sound identically in both planes.The RC-LCR disperses sound evenly.

CF-50 Tower:
This speaker is priced and sold EACH (single speakers) only. ENERGY CF-50 BLACK. Rigid, low-distortion cross-braced MDF enclosure with attractive Black Ash Finish and Black High Gloss trim. For this reason we are unable to provide price protection on orders once they are placed.

I am not recommending these as the design is getting a bit too old to be competitive and there is also some question of whether quality was sacrificed after Klipsch bought Energy and started wholesale clearance pricing them while otherwise killing off the brand (same was done to Mirage which was (I believe) a sister company to Energy.
It is interesting that they have resurfaced, and I wonder if any of you have any idea whether or not Energy might have had another production run just to see how it fared.
