  • Page 30: Power Amplifiers Selection

    user’s manual user’s manual 6 - POWER AMPLIFIER SELECTION When selecting a power amplifier, don't go for "just enough power". An underpowered amplifier will provide no performance advantages, not even in terms of reliability (indeed, loudspeakers are more prone to failure when driven by an underpowered amplifier), and the dynamics of the whole system may be compromised.

    user’s manual user’s manual Two-ohm operation. Many professional power amplifiers may operate on very low loads and some of them are specified for continuous operation on 2-ohm loads. It would therefore seem possible to employ one of these "low-impedance- capable" amplifiers to drive two parallel-connected RAB1815 subwoofers (one channel for the two 18", the other for the two 15"), or 4 parallel- connected RA16 enclosures (one channel for the four LF sections, the other for the four HF sections).
