The Best 5.1 Speaker Systems You Can Buy for $800 or Less

During our week celebrating precision audio, you guys asked about respectable but affordable home-theater audio. So we hit up CNet’s Audiophiliac, Steve Guttenberg, to clue us in to three exceptional 5.1 speaker/subwoofer combo packages selling for $800 or less.

Energy RC-Micro 5.1

Energy is big on small speakers. Their RC-Micro 5.1 system ($600) includes four satellite speakers that stand a mere 4.7 inches tall, and the center speaker isn’t a whole lot bigger. The wee 240-watt, 8-inch subwoofer is a seriously gutsy performer. The big catch with most little systems is they crush wham-bam dynamics, and their bass either booms or runs out of gas. No problem here, the RC-Micro 5.1 belts out bombast like a larger system. It’s simply one of the most refined sounding micro systems I’ve heard to date.

Mirage Nanosat 5.1 Home Theater

The Mirage Nanosat 5.1 Home Theater ($600) sounds unlike any box-type satellite system on the planet. Conventional speakers project sound forward, the Nanosat speakers produce a ratio of 30 percent direct and 70 percent reflected sound. The direct sound heads straight to the listeners, while the other 70 percent bounces off the room’s walls and ceiling before finally reaching the listeners. With the room lights turned off, the Mirage satellite speakers can literally disappear as sources of sound. The system comes with five identical satellite speakers and a rather potent mini-subwoofer.

Definitive Technology ProCinema 600

Definitive Technology is a high-end speaker company, but it is one that has learned how to sell its products for a lot less than high-end prices. Take the ProCinema 600 six-piece satellite-subwoofer system ($800). Clever engineering solutions make for an exceptional package. For example, the system’s injection-molded mineral-filled polymer speaker cabinets have more of a high-end feel than more typical plastic or fiberboard cabinets. The 250-watt, 8-inch subwoofer has a second 8-inch “infrasonic radiator,” in order to produce extraordinary deep-bass slam. The ProCinema 600’s resolution of fine detail, razor-sharp imaging, and dynamic kick are the stuff that make high-end worth it. Listen and you’ll see.

Stanford wants to roll its own paper batteries

It was only a couple of months ago that MIT was wooing us with the energy-preserving properties of carbon nanotubes, and in a classic act of oneupmanship Stanford has now come out and demonstrated paper batteries, which work thanks to a carbon nanotube and silver nanowire “ink.” We’ve seen this idea before, but the ability to just douse a sheet of paper in the proper magical goo and make a battery out of it is as new as it is mindblowing. Battery weight can, as a result, be reduced by 20 percent, and the fast energy discharge of this technology lends itself to utilization in electric vehicles. The video after the break should enlighten and thrill you in equal measures.

SmartSynch intros GridRouter for smart meters and the electric companies that love them

The last time we heard from SmartSynch it had inked a deal with AT&T to provide communications between its smart energy products and power companies. Now the company’s back with a little something called the GridRouter, an IP-based device based that connects appliances, smart grids, and utilities — no matter which communication protocol is used. The device is built on an open platform since the current grid is a mish-mash (or a hodge-podge, if you will) of proprietary hardware and software, and includes WiMax and Wi-Fi capabilities. Sounds like it just might be the thing for utilities struggling to catch up to the 21st century smarter energy revolution — and those of you who are really, really into Google’s PowerMeter beta. Want to give it a spin? Hit the source link to get in touch with the company. PR after the break.

Large Hadron Collider breaks energy record, still won’t power a toaster

CERN’s Large Hadron Collider just made the record books for something other than the cost of building a 27km-long circular tunnel. After achieving its first collision on Tuesday, the LHC roared beyond a trillion electron volts (1.18 TeV to be exact) literally smashing the 0.98 TeV energy record held by the Tevatron particle accelerator in Chicago since 2001. So far the LHC had been operating at a relatively modest 450 billion electron volts as it pushes up to full capacity of some 7 trillion electron volts. All that’s left now is the minor issue of unlocking the secrets of the universe when the real scientific testing gets underway early next year.

Spin polarization achieved at room temperature, elusive miracles now less elusive

Spintronics — much like Cook-Out milkshakes and cotton candy for all — seems like a pipe dream at this point. We’ve been beaten over the head with theoretical miracles, but we’re getting to the point where it’s put up or shut up. Thankfully, a team of Dutch boffins are clearly in the same camp, and they’ve been toiling around the clock in order to achieve spin polarization in non-magnetic semiconductors at ambient temperature. The amazing part here is that “temperature” bit; up until this discovery, spin polarization was only possible at levels of around 150 K, or at temperatures far, far cooler than even your unheated basement. If spintronics could effectively be enacted at room temperature, all those unicorn-approved phenomena we mentioned earlier would have a much greater chance of sliding into the realm of reality. Here’s hoping they get this stuff ironed out prior to 2012.

California Says Goodbye to Power-Hungry HDTVs

Panasonic's 150-inch plasma HDTV, shown at CES 2008

California’s Energy Commission voted unanimously today to set limits on the energy consumption of televisions.

The new TV efficiency standards, which go into effect on Jan. 1, 2011, limit power draw to a certain number of watts based on the total screen area. The bigger the screen, the more power it is allowed to consume. An even tighter standard will go into effect Jan. 1, 2013.

The standards apply only to new televisions sold within California. What’s more, they only apply to TV sets with 1,400 or fewer square inches (equivalent to a 58-inch diagonal screen). In other words, if you still want to buy that 1,700-watt, 150-inch plasma, go right ahead, Mr. Rich Dude! It’ll go very nicely with the polar bear rug in your den.

According to proponents, the standards will not significantly increase the sales price of TVs, and will save the average household $30 per year per TV set, for statewide savings of $8.1 billion per year. Yes, California apparently is home to 27 million TVs.

Despite that, some consumer electronics groups opposed the ban, saying it would increase costs and reduce selection.

As with emissions regulations for cars, the TV standards set by California should have a wide-ranging impact, because the state is such a big market that manufacturers are likely to make all of their products (at least the ones intended for a U.S. market) comply with the California regulations.

Dancepants: the music stops when exhaustion sets in

We’ve seen some pretty tortuous fitness wares in our day, but few are as cringe-worthy as this. The conceptual Dancepants Kinetic Music Player is a rather vanilla looking pair of exercise pants, but the internal energy makers generate juice only when the wearer is in motion. In other words, kinetic energy is used to power the connected MP3 player, and so long as you keep hustling, the tunes will keep flowing. Not like you’ll really notice that Mambo #5 has stopped right in the middle of the bridge when you’re laying on the ground nursing a wicked cramp, but hey…

Pavegen taps pedestrians for power in East London (video)

When we were kids, we assumed that in the future everything would be powered by tiny nuclear fusion reactors: automobiles, toothbrushes, time machines (apparently we read a lot of sci-fi from the 1950s). The truth, as usual, is more mundane than all that: some of the more promising advances we’ve seen in green energy has been kinetic, taking the movement of automobiles or the tides and converting it into electricity. Pavegen, for example, can be set in public walkways to generate as much as 2.1 watts of electricity per hour from the footsteps of grizzled pedestrians. Using marine grade stainless steel and recycled materials, just five of these bad boys distributed over a well-worn sidewalk should be able to generate enough energy to keep a bus stop going all night. If not put into nearby lighting, the units are equipped with lithium polymer batteries for storage. Currently being tested in East London, look for them throughout the UK in 2010. Video after the break.

US government lays out cash for wall-based, in-home ‘smart meters’

Google has its PowerMeter, Microsoft has its Hohm and Obama has his “smart meters.” Got it? Good. Around two years after UK taxpayers began footing the bill for in-home energy monitors, it seems as if America’s current administration is looking to follow suit. While visiting the now-open solar facility in Arcadia, Florida today, the Pres announced that $3.4 billion in cash that the US doesn’t actually have has just been set aside for a number of things, namely an intelligent power grid and a whole bundle of smart power meters. Aside from boring apparatuses like new digital transformers and grid sensors (both of which are designed to modernize the nation’s “dilapidated” electric network), 18 million smart meters and 1 million “other in-home devices” will be installed in select abodes. The idea here is to give individuals a better way to monitor their electricity usage, with the eventual goal set at 40 million installed meters over the next few years. Great idea, guys — or you know, you could just advise people to turn stuff off when they aren’t using it, or not use energy they can’t afford. Just sayin’.

America’s (newest) largest solar plant set to go live in Florida

If all goes well, this 25-megawatt solar plant in Florida won’t be America’s largest for long, but it’s not like we’d pass up the opportunity to let this $150 million facility bask in its own glory (and the sun, if we’re being thorough) while it can. The Desoto facility is just one of three solar projects that Florida Power & Light is spearheading, and judging by the proximity of this one (in Arcadia) to the 75-megawatt facility planned for nearby Charlotte County, we’d surmise that the two are linked in some form or fashion. President Obama is expected to show up rocking a set of Kanye glasses underneath a welder’s mask when the plant is fired up this Tuesday, and while it’ll only provide power to “a fraction” of FP&L’s customer base, it’ll still generate around twice as much energy as the second-largest photovoltaic facility in the US of A.

[Thanks, Yossi]
