Failure of a midrange panel in the SS-1A is an annoyance but by no means a disaster. If you have a mental image of pryotechnics reminiscent of starship Enterprise taking Klingon fire, forget it. Yes, there's 4000 volts DC on those panels, but it is only a static charge, with no more potential for violence than the charge you build up walking on a carpet in dry weather. When a midrange panel goes out, it may cause clicks or distortion in the sound, but in most instances, that's all there is to it. The panel is easily replaced, and you can even…

In a letter to his parents in 1930, a 17-year-old Benjamin Britten described his attendance at a London concert. The first half of the program consisted of works by Humperdinck, Mozart, and Mahler; but since the second half was to be "all Elgar," Britten and his friend left at intermission. This little anecdote vividly illustrates the clear division that had…
That was the question asked by a reader who was perfectly happy with his CD-based system. He was using the gain control provided by the variable output of his CD player and was apparently in no need of phono playback or greater flexibility. He asked us to answer this question, ignoring for the moment the obvious functions of switching, volume and tone control, and phono preamplification. With those hardly trivial qualifiers—and bearing in mind the high output available from many of today's line sources, CD players in particular—do you really need the added expense and complexity of a…
Thirty-one flavors may work for an ice-cream chain, but a speaker manufacturer who sets out to please every sonic palate ends up with a serious identity crisis, pleasing no-one. From its inception in 1985, Audio Physic, based in Brilon, Germany, has been an event-oriented speaker company. Founder and original chief designer Joachim Gerhard focused much of his attention on providing listeners with the sensation of "live" by emphasizing coherent three-dimensional imaging and soundstaging—though not to the exclusion of timbral accuracy. Except for the Medea, based on a Manger driver (a…
The crossover control's five positions adjust the woofers' low-pass frequency between 250Hz and 300Hz, allowing you to make subtle distinctions between bass that's lean and tight and bass that's somewhat warmer. You can also disable the crossover, if you want to insert an external crossover between the two modules. Also included are: a Phase button, to invert the subwoofer polarity; a Subsonic button, for LP playback, if needed; and three presets, for Small (25m2), Medium (40m2), and Large (>40m2) rooms. With the presets, you can set all parameters "in the ballpark," so you can have a…

Sidebar 3: Measurements
The Kronos offered a little higher sensitivity than the norm, at an estimated 89dB(B)/2.83V/m, though this is 2dB below the specified figure. Note that this is the sensitivity of the midrange-treble head unit, as the woofer section is powered. Similarly, the speaker's impedance graph (fig.1) shows the behavior of the head unit only. The magnitude stays close to 5 ohms throughout the unit's passband. However, the combination of 4.9 ohms and a -46 degree electrical phase angle at 250Hz will cause problems for amplifiers that can't deliver much in the way of current…
As often as not, it ain't the heat—it's the stupidity. When confronted by the smattering of self-referential dilettantes, acrimonious Internut wannabes, and obsessive-compulsive types who suck the air out of our aural fun-house, I find myself overcome with the desire to program my phaser for CLIP.
Snobs and slobs, I calls 'em, O'Boyle. The snobs patronize you with the notion that spending a lot of money is the only way to achieve audio nirvana, and make little effort to hide their contempt for your slobbish blue-collar gear. The slobs, being of a reactionary, pseudo-populist bent, assert…
