Stereo Integrity M3 Carbon Midrange Speaker (Pair)

Stereo Integrity M3 Carbon Midrange Speaker (Pair)

Our M3 Carbon 3.5″ loudspeaker is a no-compromise wideband solution for use in any high-end audio system. Smooth midrange fluidity, broad bandwidth, and low inductance are the key design elements on our M3 Carbon loudspeaker. Extensive Finite Element Modeling along with critical analysis data from Klippel USA was used to fine-tune the driver into what you see before you.

The M3 Carbon has a Carbon Fiber cone and dust cap for lightweight moving mass to keep sensitivity as high as possible while providing exceptional cone stiffness. The Carbon Fiber cone is mated to a specific custom tooled synthetic copolymer surround which aids in smooth midrange and excellent durability.

The dominant suspension damping force is provided by a Nonex spider between the spiral cut aluminum voice coil former and cast aluminum frame. Inside the motor cup lies a high-strength shielded N45 neodymium motor structure providing high motor force across a single gap motor structure. Inductance is kept low to increase the high-frequency extension up to 20,000 Hz which can negate the need for a tweeter when used on-axis.

While we call the M3 Carbon our midrange it is actually a wideband loudspeaker capable of playing from 125 Hz up to 20,000 Hz. We recommend a highpass crossover point equal to or greater than 300 Hz with a 24 dB/octave slope.
