Home theater

If you listen to music over your iPod or computer, it's safe to say you're listening in stereo.

Cars are a different story; they can have speakers in all sorts of places, so I'll grant that music in the car may not be in stereo.

But the music itself at least started out as stereo; MP3s and CDs are strictly stereo, so unless you listen to a lot of 5.1 channel SACDs or DVD-Audio discs, stereo is where it's at.

Most, but not all post-1980 films are available in 5.1. So if you have … Read more

The best of today's home theater in a box systems are excellent, but how do you find the one that's right for you?

First, read my CNET reviews; they're loaded with information about how easy the HTIB is to use and how well it performs. It may be a dubious honor, but I probably hold the record for testing more HTIBs for magazines and Web sites than any other reviewer.

Most HTIBs come with Blu-ray or DVD players, receivers, and five or more speakers and a subwoofer. Right, HTIBs also come with lots of wires and setup chores, so they're almost as complex to install as separate receiver, player, and speaker-based home theater systems.

If that's more than you bargained for, maybe you should be looking for something simpler: a single-speaker surround system? That would eliminate most of the wiring and setup hassles. Check my CNET reviews to see if one is right for you.

For small bedrooms or dorm rooms, a budget HTIB or single-speaker surround system may be ideal. Family-size home theaters may require larger systems with larger speakers and powered subwoofers.

Connectivity varies a lot in this category, so don't assume all HTIBs have what you need. If you don't want to switch inputs on your TV every time you select a different video source, say from a game system to a Blu-ray player, make sure the HTIB has enough HDMI and other video inputs. Some HTIBs don't switch video at all. Some have USB inputs and iPod-docking capabilities.

HTIBs tend to sound best with movies; music comes in a distant second place. I always refer to HTIBs' performance with movies and music, so if you plan on listening to a lot of music over your new system, definitely look for that in the reviews. Don't assume the sound will be equally good for music and movies; it rarely is. … Read more

Getting crystal clear sound never comes cheap, but Perfect8 Technologies' ultimate Perfect8 5.1 system shatters the price ceiling for glass-speaker systems.

The $566,000 ensemble consists of two Force tower speakers for the front left and right, a Force Center channel speaker, and a pair of Point speakers as surround speakers. If stereo is all that you need, a pair of Points go for a more modest $149,000. The advanced-technology designs represent the latest thinking in "see through," highly transparent sound quality.

Perdect8 Technologies is a Swedish manufacturer of high-end ribbon tweeters. dynamic loudspeakers, and subwoofers. The company was founded in 2005 with a mission: produce the world's most exclusive and best sounding loudspeaker systems.

Since I haven't actually heard any Perdect8 speakers, I'm in no position to judge their sound; however, the company is developing a buzz among adventurous and wealthy audiophiles.

I discovered Perfect8 Technologies' glass speakers on the Ultimate AV Web site.

You'll find more images of Perfect8 Technologies' glass speakers after the jump.… Read more

Sound bar speakers vastly simplify home theater setup and installation, but their sound quality always falls short of bona fide 5.1-channel speaker-subwoofer-based systems. The single-box Zvox Z-Base575 get closer to that ideal than most.

The problem with sound bars is they're too small. Even pricey bars like Yamaha's YSP-3050 ($1,199 MSRP) can't generate full-blown home theater impact. And it's a bit bigger than average (31.5 inches wide by 6.1 inches high by 6 inches deep), but films like "Mission: Impossible III" sound tepid over the YSP-3050. The film's explosive effects lack the excitement you'd get from a 5.1 system. Yamaha's technology is amazing, but it can't produce high-impact sound from skinny cabinets. I'm not singling out Yamaha here; Denon, Marantz, Polk, Samsung, and Sony sound bars all--to varying degrees--squash dynamic range of movies.

Stepping up to the YSP-4000 ($1,600 MSRP) won't make that big a difference; in my CNET review I noted that it stumbled with big special effect-driven flicks like "Mission: Impossible III." The explosions fell flat, the bass was rumbly, and the Yamaha couldn't play loud at all. Hooking up an Acoustic Research HT60 subwoofer to add extra muscle helped a little, but the YSP-4000 still lacked punch.

Part of the problem is that almost all sound bar speakers are too small. Zvox's Z-Base575 is big and very, very deep. How deep is it? Sixteen inches! So unlike other surround bar speaker systems that can either be wall-mounted or set on a shelf, the Z-Base575 was designed to be used as a base under your TV. Don't worry, the sturdy medium-density fiberboard cabinet can support heavyweight displays. … Read more

I remember listening to Ohm Acoustics speakers ages ago, but I've lost track of the company. Founded in 1971, Ohm Acoustics is still around and still building all of its speakers in Brooklyn.

Ohm speakers feature radical technology, and it's not just that they're omnidirectional designs.

Quoting from the Ohm Web site, here's how the technology works: "The Ohm CLS Driver is a vertical line source that combines inherently perfect time and phase alignment and uniform polar frequency response....At the source, the sound originates simultaneously from the face of the super tweeter and the top of the inverted cone driver..." Translation: they sound good.

The CLS Driver looks like a downward-facing cone, but its sound radiates up and out, in a near 360-degree radiation pattern. In all Ohm designs a single CLS Driver produces bass, midrange, and most treble frequencies; no wonder it sounds nothing like speakers that use separate woofer, midrange, and tweeter drivers.

During my recent factory visit I listened to a set of Ohm Micro Walsh speakers ($1,000 a pair). They're skinny towers: 36 inches high, 6 inches by 6 inches wide, and deep. Even within the huge factory space, the wee towers sounded huge. Bass wasn't super deep, but it was rich and warm. There's no need to add a subwoofer for stereo systems; and larger Ohm speakers sound much the same but can play louder and make deeper bass.… Read more

Whether it's a two-hour Grateful Dead concert or a 45-minute DJ mix, we all have an MP3 in our music collection that gets skipped for being too long. Tragically, there's usually one or two great songs in these recordings that would otherwise be in heavy rotation if they weren't tied to such a tediously long file.

Well, today we're going to show you how to cut these songs loose by opening up and editing your MP3s in Audacity. The whole process is relatively painless, and if you set it up correctly, you can easily drag and … Read more

Recession? What recession? New York City's venerable fixture of high-end audio and video, Stereo Exchange, celebrates its 25th anniversary this weekend. It's running a sale through Sunday, November 8 with substantial discounts on select products from several manufacturers. The opening night party on Thursday was jam-packed and there were no shortage of customers!

For the opening night party, many of the participating companies were demonstrating their wares. Featured products on display include: Panasonic's new 85-inch plasma HDTV; NAD's new M2 Direct Digital Amplifier; McIntosh Labs' MEN220 Room Correction System; and Grado's PS 1000 headphones, which … Read more

The Audioengine P4 is a cheap speaker.

Correction, it's an audiophile speaker that sells for $249 a pair. But that hasn't stopped it from getting raves from audiophiles who live with speakers that sell for a whole lot more.

I use Audioengine A2 self-powered speakers ($199 a pair) with my computer, so I thought I had a handle on what to expect from the P4.

I did not; it's a whole new ball game. First, the P4 is a "passive" speaker, so you need to hook it up to an amplifier or receiver. The A2 is an "active" self-powered design that can be connected to a computer or MP3 player via a headphone jack.

I started listening to the P4 with my computer, with the speakers hooked up to an old Jolida hybrid tube/solid-state amplifier. The A2 is a sweet sounding little speaker, but the P4 was dramatically clearer, cleaner, and more vibrant. The P4 blows the A2 away--it's not even close.

At 9 inches tall by 5.5 inches wide by 6.5 inches deep, the P4 looks like a larger A2 (the A2 is 6 inches high by 4 inches wide by 5.25 inches deep). The P4 comes in satin-finished black or gloss white paint for $249 a pair, or in bamboo for $325 a pair. The wood isn't merely a veneer over medium-density fiberboard; no, the P4's cabinet is made out of solid bamboo, it's gorgeous!

Audioengine offers a nifty tabletop stand, the DS1 ($29 a pair), that cants the speaker back at an angle to project sounds up. The rubbery stands also isolate the speaker and prevent it from transmitting bass into your desk. Want to wall mount it? No problem, use the threaded inserts on the speaker's rear-end.

The P4's three-quarter inch silk dome tweeter and 4-inch Kevlar woofer appear to be of very high quality. Both drivers are made by Audioengine. … Read more

Today's receivers are so jam-packed with features they can be a hassle to set up and use. Even entry-level models boast features that flagship models from even just five years ago never had.

Is that a good thing? No manufacturer offers a receiver that's dead simple to use, sounds great, and has adequate connectivity to hook up a cable box, Blu-ray player, and one or two other sources.

Do you base your buying decision on the features lineup? Does the one with the most features win? Does your receiver really need to be THX Ultra2 Plus-certified, with four … Read more
