Key Features 

Here is a brief overview of what all the speakers in the 3G line share.

Monitor Audio Platinum 3G Tweeter

3RD Gen MPD III Tweeters: These high-frequency transducers employ a Micro Pleated Diaphragm (MPD). Using a square radiating area, this design reduces distortion, widens pass-band capability, and flattens frequency response for a wider, cleaner more consistent, and lifelike Sound.

Monitor Audio Platinum 3G Woofer

RDT III Cones: Used in the midrange and bass drivers, the RDT III Cones produce piston-like control even with the most extreme performances, providing a more precise, lifelike tonal balance and lower distortion. 

Midrange Drivers: In addition to the cones, the midrange driver construction is optimized to ensure a completely smooth frequency transition with the tweeter. This is ideal for AV/Theater applications.

Crossovers: The crossovers are engineered to support the most exact and controlled sound performance across the full frequency spectrum.

Monitor Audio Platinum 3G Loudspeaker Rear Terminals

Bi-Amp/Bi-Wire Connectivity: This provides the ability to connect the HF and LF drivers to separate amplifiers if desired.

Rear Port: The 300, 200, and 100 models include a rear-facing tuned port for added low-frequency response. The C250 model is a sealed cabinet design that does not feature a port.
