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.

PCBs built by MTG Designs

Crossover Design

Heavy gauge air core inductors, precision audio grade resistors, high purity metallized polypropylene capacitors, precisely machined and soldered PCB

Smooth 12dB, 2nd order filters placed at 2 kHz

Tuned to be slightly revealing and solidly balanced in the mids and lows

High Output Woofer

Coated paper cone
‍
Excellent power handling!

Smooth, accurate, and extended response down to 40-50 Hz‍

Soft Dome Tweeter

Compact neodymium motor
‍
Ferrofluid enhances power handling and reduces unwanted resonance
‍
Provides smooth and flat high frequency extension

Cabinet Design

Elliptical cabinet interior shape is employed to reduce standing waves

Unified design merges port, cabinet walls, and internal bracing

5º rearward tilt on the front baffle better aligns the acoustic center of the tweeter and the woofer

FDMGeo Frequency Response

FDMGeo Impedance

Note: Measurement mic placed 39 inches (1.0 m) away from front baffle, on axis with the tweeter, atop a 36 inch (0.9 m) speaker stand, in a small bedroom. Frequency response plot is truncated below 200 Hz as this range tends to be room-dependent.
