Sonically, I can't find fault with these speakers for their price and configuration. They have wooed me to the touchy-feely world of in-wall speakers and made me a convert.
Noble should put stickers on the front of the speakers for those who don't read the manual so they know not to over-tighten the grills as that is an easy mistake for a newbie to make.
While more of a warning than a downside, Noble Fidelity speakers offer audiophile performance, but you need to consider positioning and upstream electronics to get the most from them. Sticking a pair of these speakers in the ceiling is certainly something you can do, but to get the most audiophile performance, you will want to get them more dialed in to an ear-level position if possible.
In-wall speakers have come a long way and are narrowing the gap with traditional box speakers. Considering the environmental challenges that the $699 Noble Fidelity L-82s were confronted with, I was very pleasantly surprised by just how good they sounded in my walls. Can they compete at an absolute level with full floor-standing loudspeaker systems? No. But then again, I have yet to hear any in-wall speaker that could. Compare these Noble Fidelity L-82s with some of the best in-wall offerings from the likes of Sonance, Speakercraft, Paradigm, B&W, PSB and RBH. The RoHS compliance is nice icing on the cake for those looking to support companies who take the time to be a little bit more environmentally conscious.
If you are a music enthusiast who is looking for an open and detailed speaker that can also pump out substantial low-frequency information, then the L-82 is a speaker you should absolutely consider. A system with five or seven of them would make an outstanding home theater system, which can blend seamlessly into even the most highly decorated living rooms. You certainly can spend more on similar in-wall speakers, but I'm not convinced you will get sound significantly better than the Nobles by laying out those extra dollars.
