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.

Coincident stereo miking (footnote 1) has two advantages and one disadvantage. Its advantages are that it gives the most stable, specific imaging of any mike technique, and its outputs can be summed for mono reproduction without loss of quality. Its disadvantage is that, in most of its configurations, it tends to produce an overly narrow, shallow soundstage.

Tandberg of Norway has a rather ambiguous corporate image among audio perfectionists. Long considered to make some of the best tape-recording equipment around, the firm has never been seen as a leader in electronics, despite some bold—and reportedly good-sounding—forays into the realm of $2000 preamps and $3500 power amplifiers. Perhaps this is why, when Tandberg started making CD players, high-enders were uncertain how to respond.

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.
