C-TIP: Although it’s beyond the scope of this manual to test and rate the many specialty
loudspeaker cables sold in audio shops, studies conducted by skilled engineers have
conclusively shown that the majority of such cables offer no real performance advantages
(and in some cases, notable disadvantages) over that of good quality industrial grade wire.
SELECTING AMPLIFIERS
Amplifiers are a vital part of any sound system’s performance capability. As such, they
should be carefully selected for appropriate power output, as well as for other attributes
(more on this later). A table is provided below to help you size your amplifiers’ power
output capability to the various models in the S-Series.
Model Recommended Power
S-1296
S-1596
S-3294
S-3594
Full-range (Passive Mode): 400 to 625 WRMS at 8Ω
S-1296
S-1596
S-3294
S-3594
Bi-amp Low-frequency: 400 to 625 WRMS at 8Ω
Bi-amp High-frequency: 100 to 150 WRMS at 4Ω
S-215S Subwoofer 800 to 1250 WRMS at 4Ω
S-218S Subwoofer 1200 to 1875 WRMS at 4Ω
Note: “WRMS” = “Watts RMS” = “Watts Root Mean Squared”
A WORD ABOUT CLIPPING
Clipping occurs when an amplifier is driven to the point where its output can no longer
accurately reproduce the waveform presented at its input. When driven hard enough its
output voltage can’t swing any higher, so the resultant waveform is said to be clipped (see
Figure 10 below).
