ESB Audio 4.G — 4000 Series 4.165 / 4.6C CNC Grille | HF Audio Labs

ESB 4000 Series — 6.5-Inch Speaker Grille

The purpose-designed protective grille for the 4.165 woofer and 4.6C coaxial. It is an optional accessory for installations where the speaker is exposed to physical contact or where a finished appearance over the driver is part of the build.

Key Design Features

Designed specifically for the 4000 Series 6.5-inch basket, the grille mounts cleanly, stays silent, and clears the cone and surround through the driver's full range of motion. A matched fit minimizes the acoustic footprint that any physical cover introduces.

System Application

Door and kick panel installations exposed to passenger contact or road debris, cargo-area placements, and builds where a finished surface is preferred over the exposed driver.

Specifications

Fits: ESB 4.165 and 4.6C (6.5-inch, 4000 Series basket).

HF Audio Perspective

If the speaker lives somewhere life happens — doors that get kicked, cargo that shifts — protect it with the grille designed for it. A matched grille does its job without becoming audible, which is the entire point.
