Table of Contents

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.

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).
