During the late 1950s, when high fidelity exploded into a multimillion-dollar industry, product advertisements bragged about bringing the orchestra into your living room. Apparently, no one realized what an absurd concept it was, but there are still many people today who believe that's what audio is all about. It isn't. There is no way a real orchestra could fit into the average living room, and if it could, we would not want to be around when it played. Sound levels of 115dB are just too loud for most sane people, and that's what a full orchestral fortissimo can produce in a small room.

PSB is a small, Toronto-based manufacturer that has been collaborating with Canada's National Research Council to try and take some of the guesswork, some would say magic, out of loudspeaker design.

The NRC, financed by the Canadian government, does basic research in many technological areas and makes its findings available to any firm wishing to use them. (Most other countries provide or encourage this kind of government/business cooperation. It is against the law in the US, to our great disadvantage.) The NRC's audio division, headed by physicist Dr. Floyd E. Toole, has devoted the last several years to the rather formidable task of defining, and assigning numbers to, the various aspects of loudspeaker performance that affect listeners' subjective assessments of their sound.

About 2200 years ago, a Greek writer named Antipater of Sidon compiled a list of the seven wonders of the world, which included a 100'-high statue of the Sun god Helios, erected next to the harbor of Rhodes on the Aegean sea. A of S called it the Colossus of Rhodes, for an obvious reason. Now there's a new Colossus, the derivation of whose name is a little less obvious, but which could justifiably be included in any contemporary listing of the seven wonders of the audio world.

I was so impressed by the Nelson-Reed 8-04/B loudspeaker's low-end range that I seriously doubted the add-on subwoofers could add enough of significance to be cost-effective.

I was wrong.

Two of the subwoofers were provided, along with the necessary electronic crossover unit. Each 1204 unit contains four 12" woofers in a very solid sealed enclosure, with two facing to the front and two facing the rear. The electronic crossover has three controls, besides the AC power switch: a hardwire (footnote 1) bypass switch, a stereo/mono switch, and a subwoofer level control. In the stereo mode, the low frequencies are kept separate, left from right; in mono mode, they are blended together for feeding to a single subwoofer. I will not resurrect the question of whether or not it is important to maintain stereo separation into the LF range, except to echo N-R's observation that there is no LF separation on analog discs to begin with; the lows are mixed together, to limit vertical excursions of the cutting stylus that could cause it to rise above the disc surface or, worse, dig into the aluminum base of the master disc.

If you read my article in these pages about recording the Cumbres and Toltec Scenic Railway steam trains (January 1987, Vol.10 No.1), you may recall the mention of Colossus. Colossus is the name of a new digital recording system which designer Lou Dorren claims to be different from every other digital system in several ways, none of which has ever been disclosed to us. I had a chance to listen to some tapes made on it shortly after writing the C&TSRR article, but since they were made with a completely unfamiliar microphone (Mobile Fidelity Productions of Nevada's own design) and featured mainly the sounds of trains, airplanes, and other sources of potential ear damage, I couldn't really tell anything about the recording system, except that it had the kind of low end I expect from any respectable digital audio. A sonic evaluation had to wait until I heard Colossus on more familiar terms—that is, with music recordings. Now, that time has come.

According to designer Bill Reed, the Nelson-Reed 8-04/B was not originally intended to be an audiophile speaker system, but was instead designed as a high-quality monitor for the critical recording engineer who wanted to be able to walk from the studio into the control room and hear the same thing from his speakers that he heard "live." The fact that modern studio mike technique ensures that this could never happen is probably beside the point. The point is that reproducing the original power and dynamic range of live music is a formidable challenge, which practically no audiophile speakers have met successfully. On the other hand, so-called studio monitors, which can do that routinely, have tended to be highly colored and otherwise generally lousy in all areas of fidelity except output capability. The 8-04/B was an attempt to combine the strengths of both kinds of speaker, while avoiding their usual weaknesses.

Every once in a while, and particularly around the first of the year, news writers (of which I am one) get the urge to play oracle, laying our credibilities on the line by attempting to divine what the coming year will bring. Since I am writing this at the end of January, the chances of my miscalling my shots have already been reduced by a factor of 0.083. But there are still 11 months to go, and some possibility that a prediction or two may be wrong. Nonetheless, I shall intrepidly grab the bull by the horns, the crystal by the ball, and the opportunity of the moment to take an educated guess at what the rest of 1988 holds for audio.

Now that Sony has bought CBS's records division, and the infamous Copycode bill seems to be dying in Congress, the way may be clearing at last for the US introduction of the new Digital Audio Tape system. This has sparked renewed speculation in the industry about the impact DAT will have on existing formats, particularly the fledgling CD. Some are convinced DAT will kill CD, because of its ability to record as well as play digital recordings. Others believe DAT won't even gain a foothold in the market, for the same reason quadraphonic sound laid an egg back in the '70s: The public can't handle more than one "standard" format. I feel that both views are wrong, and that—as is usually the case with extreme views—the truth lies in between. I believe DAT will catch on in the marketplace, but never in a big way, and certainly not the way CD has. Here's why.

When I attended the Audio Engineering Society convention in October 1987 (my first time in over eight years; full report in this issue), I was impressed by the incredible technology now available to composers of music. I was also dismayed, however, by the extent to which so-called purist audio, as well as "acoustical" music, have been consigned to oblivion by the pro audio community. It was clear, both from the exhibits and the many conversations on which I eavesdropped, that audio professionals are no longer concerned about fidelity, in the sense of trying to reproduce sounds accurately. A "real" sound has become to them merely raw material of no value except as something to be processed, manipulated, folded, bent, and spindled to produce any sonic effect except the original one. About a third of the products displayed at the 83rd AES convention were tools for doing that.

The Ortofon MC-2000 may just have been the most impractical cartridge to be unleashed upon the audio community for some years. With a high compliance (20cu) that made it ill-suited for most tonearms, it also had a preposterously low signal output of 50 microvolts, which gave new meaning to the terms hum and noise. Few MC preamps had enough gain to deliver adequate driving voltage to a system, and none of those that did had low enough noise to be usable with the 2000. If the problem wasn't hum, it was hiss; if hiss was acceptably low, there would be too much hum. At least Ortofon had the sense to be aware of the problem and to do something about it, in the form of their T-2000 step-up transformer, which is the only device I ever found that would allow the cartridge to be operated without a constant background of hum or hiss. Despite all this, I have used the MC-2000 as my reference cartridge for the last two years. Why? Because of all the cartridges I've tried, it is by far the most accurate.
