Expert and User Opinions


Sound Quality: Reviewers often praise the M2s for their excellent stereo imaging, impressive dynamics, and deep bass extension that is unusual for their size. Some users note a "precise and forward" sound, which might be a "love it or hate it" experience for some listeners.

Performance: The active design (integrated amplifier and electronic crossover) offers technical advantages, such as matched components and protection against driver overload, resulting in a cohesive sound.

Compatibility: The M2 speakers were typically designed to pair with the Meridian 101 preamplifier, though users suggest that a high-quality pre-amp is essential to realize their full potential.

Maintenance: Due to their age (introduced around 1979-1981), the internal capacitors may need upgrading or servicing to perform optimally.

Positioning: Several users and experts recommend using tall stands to position the tweeters at ear level for the best high-frequency response and soundstage.
