HiVi M4N 4-Inch Aluminum Midrange Driver — Includes Install Kit

HiVi M4N 4-Inch Midrange — With Installation Kit.

While often compared to the popular B4N, the HiVi M4N serves a different engineering purpose. This 4-inch driver delivers the high stiffness and low mass needed for clean transient attack and great midrange reproduction. The M4N was designed for specific enclosure types. With a resonant frequency (Fs) of 69 Hz and a high total Q (Qts 1.08), this driver is perfect for sealed enclosures, or as a midrange driver in a 3-way speaker. In a small sealed chamber, it delivers a smooth, controlled rolloff without the peaky port behavior common to high-Q woofers.

The anodized aluminum-magnesium alloy cone has a unique copper/rose-gold finish that's a bit lighter than the B4N woofer. The overall look really catches your eye and blends great with wood finishes or painted cabinets. The cone is paired with a durable rubber surround and a damped spider to control edge resonances. It has a rigid stamped steel frame and a fully shielded ferrite magnet system, eliminating stray magnetic fields in tight AV or desktop setups.

To save you a trip to the hardware store, we include a custom-matched Installation Kit at no extra charge so you can start building immediately. Each M4N woofer you buy comes with a pre-cut gasket, two quick connect terminals, and mounting screws for free.

Highlights

• Rigid Metal Alloy Diaphragm: Lightweight aluminum-magnesium cone provides excellent response through the midrange with a standout copper/rose-gold look.
• Optimized for Sealed & Midrange Use: High Qts (1.08) and 69 Hz Fs eliminate the need for port tubes, excelling in small sealed enclosures or dedicated 3-way midrange sub-enclosures.
• Fully Shielded Motor Assembly: Ferrite magnet prevents magnetic leakage, making it safe for nearfield workstation setups and home theater center channels.
• Complete Installation Kit Included: Ships with the exact matching mounting screws and quick-connect wire terminals needed to start your build immediately.
