FDMGeo Loudspeakers

The "Geos" are edgy, literally 😎

We've combined the sugary sweetness of the FDM5 top-end with an accurate and punchy mid-section and bottom end. If you're into critical listening, or even mixing and mastering, the FDMGeos are for you!

The FDMGeos will party all night long and wake you up in the morning with a fine cup of Espresso.
