This is a rare pair of Infinity Beta 50 speakers that have been fully tested. They are designed as bookshelf speakers with a rectangular shape and a sleek black color. The system configuration is 2.0 channel with banana jack audio inputs and wired connectivity. The RMS power is an impressive 200 W, providing amazing sound quality. These speakers are a great addition to any home audio system and are sure to enhance your listening experience.

But Infinity certainly makes a case with its updated Beta series, a line that ranges from the Beta 10 bookshelf monitors ($165 each) to the Beta 50 tower speakers reviewed here. At $998 a pair, the Infinity Beta 50s arent cheap, but they are a treat to listen to--for both movies and music. The Infinity Beta 50 is a big speaker--41.3 inches tall, 10.4 wide, and 14.6 deep--and when we unboxed it, we didnt doubt its listed 62.5-pound weight. If that heft doesnt convince you of its robust build quality, a knuckle rap on the cabinets side flank will. The monolithic tower is available in black and cherry vinyl finishes, and its form-fitting metal grille is a distinctive styling touch. If the Beta 50 is just out of your price range, check out the $399 Beta 40; its a near twin of the 50 but uses slightly smaller woofers.We imagine most Beta 50 buyers will match the towers with a full set of Beta-series speakers and an Infinity subwoofer. For our Beta review package, we selected the Beta C360 center speaker ($399), a pair of Beta 20 monitors as surrounds ($199 each), and the CSW-10 subwoofer ($999). The entire system retails for $2,794, but when you stop and consider that this ensemble can easily fill even a fairly large home theater with high-impact, feel-it-in-your-guts sound, the price is pretty sane. Its more affordable than most plasma TVs, and it will blow your socks off when you listen to music. Alternatively, you could pick up five Beta 10 satellites and the $799 SW-12 sub, which drops the price to $1,624. Feel free to mix n match among the Beta-series models and build a system that fits your needs.8.0Infinity Beta 50THE GOODSensational-sounding full-size tower speakers; three-way design; high-tech drivers; form-fitting metal grilles; all-metal connectors.THE BADTheyre large (dubious spousal acceptance factor).THE BOTTOM LINEIf you have the room to indulge your home-theater fantasies on a grand scale, Infinitys Beta towers merit serious consideration.The Beta 50 is a beneficiary of Infinitys patented Ceramic Metal Matrix Diaphragm (CMMD) speaker-driver technology originally developed for its high-end Prelude MTS models. CMMD drivers are said to be lighter and stronger than conventional paper, plastic, or metal drivers. According to Infinity, CMMD drivers produce lower levels of distortion for a more transparent and detailed sound.The Beta-series tweeters have recently been revised to extend their ultra-high-frequency response out to 40KHz to enhance their performance with SACD and DVD-Audio discs. The tweeter is mounted in a special waveguide to ensure improved high-frequency dispersion throughout the listening room. We also noted that the engineers positioned the tweeter unusually close to the midrange driver, and that close proximity further improves the speakers sound quality and imaging precision.The infinity Beta 50 is a three-way, four-driver design featuring dual 8-inch woofers, a 5-inch midrange, and a 1-inch dome tweeter--the lot of them are CMMD drivers. The rear of the speaker houses a biwire set of all-metal connectors.The Betas sound quality is significantly improved over that of the Infinity Primus models we tested last year. The new speakers are more detailed and live-sounding overall, and the tweeters treble range has more sparkle and air. The new sound is more articulate and precise, so we heard more three-dimensional space in our DVDs and CDs, and when we doused the lights, the big speakers all but disappeared as sources of sound.With the Alien vs. Predator DVD cranked up to a satisfyingly loud volume, the Beta system was a force to be reckoned with. The ungodly shrieks, ongoing carnage, and massive explosions made us jump, and the movies ominous atmospheres were well served by the all-Beta system. If you love big special-effects movies, the Betas wont let you down.The Ray Charles biopic DVD Ray presented an opportunity for the Beta system to rear back and shout. Rays voice sounded absolutely fabulous--it was big and warm--and his trademark growl will send shivers up your spine. The scene where Ray Charles first improvises what turned out to be a megahit, Whatd I Say? best demonstrates what makes the Infinity Beta 50 so special. The tune starts with Ray laying down a funky groove on his organ, and the band slowly comes in. Even the crowds applause sounded right--few speakers in the Betas price class sound as convincingly realistic. Later on in the film, theres a recording session with a roomful of violins, and the Betas sounded like a set of high-end speakers.We ended our auditions in two-channel mode, listening to the Beta 50s on their own. Radioheads Kid A CD projected a near holographic soundfield--the Beta 50s stereo was so remarkably three dimensional, we thought we had accidentally turned on our receivers Dolby Pro Logic II surround processing. On some tracks, Radioheads highly textured sound hovered just behind the plane of the speakers. The bass was deep enough to convince us that some buyers might be able to forgo a subwoofer.We guess you can tell we were blown away by Infinitys Beta 50s, and we didnt want to send them back. Theyre that good....As you can see from the above article, the original price back then was $998 for a pair. Obviously, I will not be asking for a similar price although I will be using that as a reference price. Note that there are no grills and the slot where the grills are supposed to be attached are stuffed with the part that holds the grills.
