Q: What amplifier power is needed to properly drive the D 590?

Nominal power vs dynamic power The D 590 has a nominal power of 150 W and a maximum power of 200-280 W continuous according to IEC 268-5 standards. This latter measurement is the true capacity of the speaker, not a peak power. Why this distinction? Many technical specifications confuse dynamic power (very short peaks) and continuous power (in steady state). For example, an amplifier rated "220 W dynamic at 4 ohms" may only provide 100 W of continuous power at 8 ohms - these are two different measurements that do not have the same technical meaning. Recommended amplifier To fully utilize the D 590 according to its true capabilities, an amplifier offering at least 150-200 W continuous power at 4 ohms (the impedance of the D 590) is required. The technical specifications of an amplifier should always specify the continuous power at 4 ohms, not just the dynamic or at 8 ohms alone. An amplifier rated at 100 W continuous at 8 ohms remains compatible with the D 590 at moderate listening levels, but does not fully exploit the technical specs of the speaker.
