Introduce exceptional vocal clarity and premium mid-frequency dynamics into your vehicle with the BMW 4" Speaker Upgrade Type 2. Centred around the highly acclaimed Helix COMPOSE i3 Series, this vehicle-specific retrofit midrange driver completely transforms your factory acoustic layout. Engineered under the philosophy of "developed inside the vehicle, for the vehicle", this premium upgrade delivers studio-quality midrange tracking without requiring any destructive modifications to your vehicle's physical interior lines, retaining a perfect factory appearance.

Key Benefits

Smart 3-Ohm Technology: Specifically engineered to bridge the gap between traditional impedances, squeezing extra efficiency and power output out of your factory system or upgraded Match/Helix DSP amplifiers.
Cenosphere Coated Paper Cone: Incorporates hollow micro-spheres embedded into a polymer layer on the membrane, creating an extraordinarily light yet stable cone for high-fidelity sound reproduction.
Resonance-Free High-Tech Basket: Crafted from a polymer composite reinforced with glass beads, ensuring maximum mechanical stability and low thermal expansion while completely minimizing chassis resonance.
Shallow Neodymium Layout: Compact magnet system architecture allows a minimal mounting depth, solving tight space issues common inside luxury vehicle panels.

Installation
Please Read Before Purchasing
Our Plug & Play (PnP) upgrade packages are listed primarily for professional integration, but some may also suit confident DIY users, particularly those based on MATCH or drop-in speaker configurations.

Who These Packages Are For
These packages are:

Designed for specific vehicle models
Mostly Plug & Play in design
Intended for experienced installers or trained professionals

While MATCH systems and direct physical speaker retrofits are generally more accessible for DIY installations across Australia, high-end HELIX packages typically require advanced tuning skills to unlock their full acoustic potential.

🔧 Installation & Tuning
Notes
Most packages install easily utilizing the included vehicle-specific speaker adapters, but minor modifications may be needed depending on your vehicle’s exact year and trim.

Please note:

Installation fees are not included in the product price.
Local Sydney clients can contact our Rockdale workshop for a complete quote including supply, professional door card removal, installation, and tuning.
MATCH & HELIX DSP amplifiers in particular are premium tuning products and will deliver exceptional results when tuned by professionals.
