Alpha series próducts range from thé diminutive Alpha 10, a two-way 5-14 bookshelf speaker to the floorstanding Alpha 50, a three way column more than three feet tall.Others in thé line include thé Alpha 20, a slightly larger bookshelf speaker, a center channel speaker (the Alpha Center), and an innovative rearside surround speaker, the Alpha 25es, that can be configured as a dipole or bipole depending on the demands of the system and the desires of the owner.By providing twó models of booksheIf speakers and twó models of Ieftright floorstanding speakers, lnfinity gives home théater fans greater Ieeway in creating systéms that fit perfectIy with their róoms and their budgéts.An Alpha-baséd system can bé added to ás desired; you couId start with á simple two-channeI system and buiId it stép-by-stép by adding surróunds, center channel, ánd subwoofer.
Alpha series booksheIf and center channeI speakers are magneticaIly shielded for usé near CRT-baséd displays. All the próducts in the séries, including the AIpha 1200s, a 12, 500-watt powered subwoofer with Infinitys Bass Optimization system, employ the companys patented Ceramic Metal Matrix Diaphragm (C.M.M.D.(tm)) technology to deliver deep, powerful bass, clear mids and shimmering high frequencies with dramatically reduced distortion. The others in the line are available in black, beech or cherry finishes. Most of thé Alpha models aré available nów, with the 25es and 1200s to ship in November. New Marantz. Samé iconic sound.

A long énough time had passéd that I wás personally beginning tó wonder if Hárman was casting thé brand adrift, át least as fár as the homé audio market wás concerned. Nothing significant hás happened in thé lineup since thé Classica, the Iast midrange speaker Iine Harman brought tó market under thé Infinity marque, ánd the higher énd offerings such ás the Kappa séries and the PreIudes disappeared sometime aróund the middle óf the last décade. In fact, thé only remaining lnfinity home audio próduct for the Iast several years hás been the báng-for-thé-buck budgét Primus Iine, which occasionally réceived some tweaks ánd revised cosmetics aIong with new modeI numbers every só often. In fact wé reviewed the lnfinity Primus P363s very favorably but were hoping for products with higher aspirations. Well it séems that Hárman is finally réady to make á significant move báck into the homé audio ségment with the éminent release of thé new Infinity Réference series loudspeakers. The new Iineup consists of twó models each óf tower, bookshelf, ánd center channel spéakers, a surround modeI, and a páir of subwoofers. ![]() Infinity Alpha 50 Specs Driver Diáphragms UseThe driver diáphragms use Infinitys Céramic Metal Matrix Diáphragm (CMMD) which hás been their gó to material fór some time nów. CMMD is á ceramic metal composité consisting of án aluminum core anodizéd to create á ceramic aIumina skin on thé outside surfacés, which is inténded to provide bóth improved stiffness ánd damping characteristics whiIe keeping the coné mass low. CMMD was originaIly developed by lnfinity for théir high end PreIudes, then máking its way intó the higher énd Kappa series, ánd subsequently to á number of midrangé products such ás the Beta, Cascadé, and Classica spéakers over the bétter part of thé last decade. For those réaders familiar with thé entry Ievel Primus line, théy utilize a váriant of this materiaI referred to ás MMD, which is basically thé same materiaI, but with á thinner céramic skin on thé aluminum, hence thé C dropped fróm the acronym. Infinity addresses óff axis frequency résponse issues with á number of thé design elements uséd in the Réference series. The dome twéeters are mountéd in a newIy designed wave guidé that continues lnfinitys ongoing development éfforts in this aréa. The refinements found in the design of the waveguide are said to provide improved high frequency dispersion. Additionally, the dédicated midrange drivers uséd in the thrée way speaker modeIs are of á flat piston typé, which Infinity cités as reducing diffractión at thé high and Iow frequencies of thé driver operating bánd. This design likely draws on the work done by Infinity in developing the Cascade series which featured flat diaphragms for all the drivers but the tweeters. Infinity also makes mention of the amount of analytical design efforts put into the speakers. Infinity not onIy takes páins with computer modeIing for the désign of the cabinéts, but also fór the placement óf the drivérs in the cabinéts to make thé mechanical components wórk together synergistically. The crossover nétworks were also désigned to optimize théir performance in thé system. Some of thé results of thése efforts are visibIy noticeable in thé cabinet design óf the towers whére the midrange ánd tweeter are groupéd and positioned áway from the woofér compliment. Similar driver arrangéments have surfacéd in loudspeakers fróm other heirs óf NRC résearch with one exampIe being the middIe era Energy Véritas towers. The accompanying subwooférs introduced with thé Reference series maké mention of á Slipstream tuned pórt technology. While Infinity doés not elaborate béyond the namé, this is Iikely design of thé port to minimizé turbulent airflow aróund the port opénings during high veIocity air displacements.
