Conductive Speakers – Loudspeaker transducers which affix to walls or ceilings have been around for many years. So have “butt-shaker” transducers to fasten to seating for the very lowest frequencies, down into vibrations more felt than heard. But now at least one firm is offering full range conductive speakers which use surfaces such as drywall, glass or even concrete to conduct and distribute sound. Their frequency range is said to be from 70Hz to 15kHz, with the range below 70Hz handled by normal speaker enclosures. The transducers can be mounted inside the walls to be completely hidden and without having to alter a room’s design. The company is Induction Dynamics and their web site is www.soliddrive.com
Heifetz Box 45rpm Vinyl Boxed Set – Classic Records has introduced the ultimate holiday gift set for the vinyl-centered audiophile: 33 single-sided 12-inch 45rpm stereo discs of the nine Jascha Heifetz RCA Living Stereo albums which Classic had previously reissued in 33rpm form. They come in a deluxe road case, and include the famous violin concertos by Brahms, Beethoven, Tchaikovsky, Prokofieff, Sibelius, Mozart and others. Each disc is a heavy 200 gram Quiex SV-P vinyl pressing, one side only for total freedom from groove echo and resonance and a better interface with the platter. In AudAud comparisons of previous Classic 45rpm reissues (180g, recorded both sides) with standard LP, standard CD, 33rpm reissue and even prerecorded open reel tape, the 45rpm format always came out on top. But be prepared to get up and change discs every eight minutes or so. Price of the new Heifetz Box Set is $600.
