Stereo Integrity M3 Carbon 3.5" inch 4 Ohm (M3 Series) Midrange Car Speaker 100 Watts RMS (Pair)

Our M3 Carbon 3.5″ loudspeaker is a no-compromise wideband solution for use in any high-end audio system. Many months were spent on the development of this unique 3.5″ driver where we started with various motor platforms (multiple-gap, single gap, etc), surround geometries, cone materials, etc, all while using Finite Element Modeling along with data from Klippel USA 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 excellent cone stiffness. The Carbon Fiber cone is mated to a specific custom tooled synthetic copolymer surround which aids in smoother midrange and excellent durability. Inside the motor cup lies a high-strength shielded neodymium cup 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 500 Hz with a 24 dB/octave slope.
