Q: Is the JBL Concert A704 suitable for powering both front and rear speakers?

Q: What kind of speakers pair best with this amplifier?

A: The amp excels with a wide range of speakers — component systems for clarity, coaxials for a compact upgrade, or bridged pairs for higher-power sub/satellite setups. Use the adjustable HPF/LPF for optimal matching.
