Stick it in your wall: Polk Audio has introduced three new subwoofers aimed at the custom installation market. The $600 CSW88 is a sealed in-wall model featuring dual 8" long-throw, shallow-basket woofers mounted behind a metal pressure plate. Its enclosure is constructed from MDF with 1/8" aluminum panels. It is designed to fit within standard stud-wall construction, measuring 60" (H) by 13.5" (W) by 3.5" (D). Rather than a grille, the CSW utilizes a vent, which, not at all coincidentally, measures the same as a standard 10" by 4" heating vent. Inputs on the top and bottom of the enclosure simplify wiring.

Will the future of audio distribution be dominated by discs or downloads? Will we always have both?

As the cost of data storage has continued to plunge, some industry pundits (well, www.stereophile.com's Jon Iverson) have predicted that the next step in adding value to them would be to give the devices away, but sell the music or data they contain. On March 10, online music label Magnatunehttp://www.magnatune.com">Magnatune; and Samsung spin-off Hana">http://www.hanamicron.com/">Hana Micron fulfilled that prediction with a product called the TunePlug: It's a reusable USB flash memory drive that comes loaded with 10 complete albums from Magnatune artists in MP3 file format.

Stereovoxhttp://www.stereovox.com">Stereovox; has introduced a more affordable Studio series of cables to complement its extravagant Reference products. (John Marks raved about them herehttp://www.stereophile.com/thefifthelement/742/index2.html">here;.) The new Studio HDSE (high-definition single-ended) interconnects are thin and flexible, but each cable is constructed from a single high-purity 0.008" thick copper tube, clad in a silver-plated copper woven shield, with pure tape-wrapped full-density PTFE Teflon dielectric and an FEP jacket. The Studio cables employ a new chrome-plated Xhadow™ Reference precision-machined RCA connector.

Depending on who you talk to, so far in the US, DualDisc has either been a success (according to the record labels) or a stumble (according to the press and manufacturers). Now Europe gets a chance to see what the fuss is all about.

Researchers at the International Center for Hearing and Speech Research (ICHSR) have found that age-related hearing loss may be all (or at least mostly) in your head rather than a problem with your ears.

Gunther Frohnhöfer, Acoustic Signature turntable designer and company owner, informed me last week that the business relationship between his company and Ballmann, the manufacturer of the German Behold line of electronics, which includes a headshell-mounted 768kHz/24-bit A/D converter (see my "Analog Corner" column in the forthcoming April 2005 issue of Stereophile), has been severed. Frohnhöfer has relinquished his position as Ballmann's general manager. "Doing both my own product and the Behold electronics line was too much for one person to handle," he told me. Instead, Frohnhöfer will focus on his core turntable business, while Mr. Ballmann will continue developing, manufacturing, and marketing his electronics line.
