Phoenix Gold ZDBMW4CS 120W BMW Speaker Upgrade Kit – Premium Plug & Play Audio Enhancement
The Phoenix Gold ZDBMW4CS is a high-performance 2-way component speaker upgrade kit engineered specifically for BMW vehicles. Designed for plug-and-play installation, it dramatically improves clarity, midbass response, definition and overall sound balance—solving the limitations of the factory BMW Basic Audio System.
Engineered for Clarity, Precision & Realistic Sound
- 4” Aluminium Midrange Driver – delivers tight, punchy midbass and accurate vocal reproduction.
- 1” Silk Dome Tweeter – produces smooth, refined high frequencies with zero harshness.
- Dedicated 2-Way Crossovers – ensures seamless transition between drivers for balanced sound.
Smart Bass Blocker Technology (BMW Basic Sound System)
In BMW Basic Audio systems, the door speakers receive deep bass frequencies they are not designed to handle. This causes distortion and muddy sound.
The ZDBMW4CS includes an integrated Bass Blocker Filter (120Hz, -12dB/Oct) which:
- Blocks unwanted low frequencies from reaching the 4” speakers
- Improves clarity, loudness and midrange accuracy
- Allows underseat woofers to handle bass properly
- Delivers a clean, balanced, distortion-free audio experience
Precision Fitment – True Plug & Play Installation
- Dual aluminium BMW mounting brackets for perfect fitment across multiple BMW platforms.
- No cutting, no coding, no modification required.
- Includes for a direct replacement install.
