Harwood Monitor 13 is a speaker with Harwood magnetostat and bass driver. The bass reflex design ensures an astonishingly wide frequency range and the kit is excellent value for money.

Excerpt of the Hobby HiFi review:

... "placed solidly, the small Harwood Monitors succeeded in projecting a clear and tight sound, with lots of air and without the commonly displayed super high frequency exaggeration. The vocals' tonal balance and realism were absolutely enthralling. Even the bass by these slim 2 way monitors was tight and clear. The double bass was quite authentic. Just the lowest bass, more guesswork than audible, was somewhat of a compromise. The Harwood Monitor 13 showed an exceptional three-dimensionality with excellent width and depth and precise placement of vocals an instruments. Besides, they handled higher volumes surprisingly well. " ...
