AMPLIFIERS – RECOMMENDATIONS
Martin Audio MA Series two channel power amplifiers are recommended for use with CDD Series
loudspeakers and CSX Series subwoofers. These amplifiers work well down to 2 ohms, making
it possible to power up to four cabinets in parallel from each channel. Models are available with
power ratings from 700 W/ch to 4000 W/ch (into 4 ohms).
Other manufacturers' power amplifiers may be used provided they are capable of delivering
the necessary power into the combined impedance of the cabinets in use. Note that many
amplifiers suffer sonic degradation when driving low load impedances or, worse still, shut down.
Always check your intended power amplifier's specifications and conduct listening tests before
committing to a very low impedance system design.
The table below specifies the recommended minimum amplifier rating for each model of
CDD Series and CSX Series cabinet. The "Recommended models" column lists the Martin Audio
MA Series amplifier models suitable for each speaker model.
