Martin Logan Dynamo

Compact and well-built ; speedy, tuneful delivery ; goes deep considering size

Doesn’t have enough grip or volume on movie soundtracks ; audible rattle when troubled

A valiant effort from Martin Logan, but class-leaders won’t be losing any sleep

Superior construction quality, compact packaging and unusual flexibility, A refined performance with a good perception of bass depth and speed, Good for stereo and multichannel systems alike

The 13-watt 'standby' power rating is unimpressive, Forward-firing option should be avoided for best results

Compact, powerful and well controlled, this is a classy and well-designed subwoofer that delivers a solid performance in mixed-purpose systems (hi-fi/AV), though arguably it's at its most impressive with compact, quality stereo systems
