1. Full-range / Parallel – Is the amplifier power required to optimally drive this speaker system when used in
full-range (passive) mode. In the case of dual-driver subwoofer models, this is the power required to drive
both transducers at the same time.
2. HF – Is the amplifier power required to optimally drive the high-frequency section of this speaker system
when used in bi-amp mode.
3. LF – Is the amplifier power required to optimally drive the low-frequency section of this speaker system
when used in bi-amp mode.
4. Discrete – Is the amplifier power required to optimally drive an individual transducer in a dual
transducer subwoofer.
5. ± 1 or ± 2 Pass-Thru - This allows for the convenience of a single conductor cable from the amplifier rack to
the speakers stack, this configuration supplies separate amplifier power to the subwoofer (ie ± 2) and to the
mid-high speaker (ie. ± 1 Pass-Thru).
The following table shows the recommended amplifier power for SR-X models. For applications in which
the ability to reproduce brief, high-power transients is important, an amplifier capable of up to twice the
power listed below may be used.
