Question: Any recommendations for speaker wire?  I noticed some speaker has different gauges.  Thank you.
Document: The keyhole is a bit tight for the speaker mounts that I have... it works, but takes some tweaking.- The speaker wire connection could stand to be larger to accomodate large gauge wiring. I use two 16 ga. wires in a twisted pair for each connection and they just barely make it... again, not a big drawback, but would be an improvement.- The subwoofer is good, but will not rock the house... not out of the box.
I spent a lot of time looking and listening to different speaker systems. I just couldnt find more bang for my buck. These sounds great in my house. I have no problems. I would recommend buying this product. These are a new line made by Klipsch.
Again, I'm no audiophile but there's a lot of helpful information on the web and I also called the manufacturer, Energy, on a couple of occasions for technical help and they were fantastic. Don't be intimidated by this. Tweaking settings really matters but Energy will guide through the process and it takes only minutes. Never hesitate to call Energy's tech help. You'll get a real person right away, friendly and helpful.Monoprice is an excellent source for speaker wire.
General good quality sound but do not expect to surprise you if u have floor stand speaker cos they are very different in term of stage sound. However, they give good quality sound considering their size.
The satellite speakers are small (smaller than Bose satellites for a comparison), look really nice, and sound great. The sub has plenty of power, great range, and can pump out as much bass as you'd like. I found this system for $500 cheaper on a different website (crutchfield), so shop around.I boughtAtlantic Satellite 77305018 2 Speaker Stands (Black)for the satellites, and they fit the speakers perfectly.
Mediabridge cables and wire. In a 15x14 room.So I spent just under $700 for everything. I'm happy as I have ever been with any purchase, ever. I set my bluray player to bitstream and turned "ADC" on for my receiver under options and other than that, set it up by the book.It's bliss. Quality is second to nothing in its class or price range and neither is the sound IMHO.
I am very satisfied, the only  encounter was a week or two after receiving them and I was changing them to floor  stand and realize that one of the spring connectors stuck and will not open all the way for wire to go in. Since the proplem was not that big and I was able to force the wire in, I decided to sent an e-mail through Amazon to the seller Sound Seller telling them about the defect.
Even after the Energy speakers were broken in, they were never "warm" enough - I really noticed the lack of low midrange.
These are average at best. Would recommend listening to these prior to purchasing, sound is always subjective , others may have a different opinion.
The best bet is wall mounting or as close to the wall as your can, as it uses the wall to reinforce the sound. I set the mains to 120 hrz which seemed to be the best blend with the sub.FYIMy listening space is 10 from the tv with the couch against the back wall with a sliding door on the left, dining room and kitchen 20 feet away on the right. With a coffee table 3 feet away from the sub  with the driver pointed at it. Every room is different.
Answer: RCA 16 gauge works quite well
