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

The HiVi M4N-B is a 4-inch midrange driver featuring a stealth black anodized aluminum-magnesium cone and a fully shielded motor. With an 8-ohm nominal impedance, a 70 Hz resonant frequency, and a high total Q (Qts ~1.0), it is purpose-built for sealed enclosures, compact desktop satellites, or dedicated midrange duty in 3-way designs.

Product Highlights
  • Alloy cone in a low reflective matte black finish.
  • Ideal for sealed box alignments and dedicated midrange chambers.
  • Fully shielded prevents stray magnetic fields in desktop workstation and AV setups..
  • Free Installation Kit included.

Frequently Bought Together

HiVi M4N-B 4-Inch Midrange — With Installation Kit.

The HiVi M4N-B expands on the proven architecture of the M-series, but with an all-black appearance. The matte black anodized aluminum-magnesium cone fills a cosmetic gap for builders who like the acoustic profile of the M4N but prefer the non-reflective black look on their front baffle. In a small sealed chamber, it delivers a smooth, controlled rolloff in the critical vocal range without the peaky port behavior common to high-Q woofers.

Electrically and mechanically, the M4N-B is designed with a resonant frequency near 70 Hz and a high total Q for sealed and isolated-chamber alignments. In a modest sealed enclosure or dedicated 3-way midrange chamber, it delivers a smooth, gradual roll-off on the low end without any boomy exaggerated bass. This allows for simple crossover design between 150 Hz and 5,000 Hz.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-B woofer you buy comes with a pre-cut gasket, two quick connect terminals, and mounting screws for free.


Highlights

  • Rigid Metal Alloy Diaphragm: Matte black aluminum-magnesium cone provides excellent response through the midrange with an all black appearance.
  • Optimized for Sealed & Midrange Use: High Qts (1.08) and 69 Hz Fs excells in small sealed enclosures or dedicated 3-way midrange 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.
