12 Inch Subwoofer Driver with
135mm Double Magnets
Bring articulate, low-frequency authority to your sound system with the 4D Furnishers 12 Inch 135mm Double Magnet Subwoofer Driver (Model: S-135). Specially engineered to bridge the gap between high-SPL automotive bass and refined home theater performance, this versatile 12-inch driver reproduces tight, chest-thumping sub-bass without harmonic distortion or dynamic power compression.
Constructed around a heavy-duty 135mm double-stacked ferrite ring magnet engine, a high-temperature voice coil, and a reinforced composite cone with perimeter colored accent stitching, this driver is built for custom DIY enclosure builders and audio enthusiasts demanding uncompromised sound quality.
Key Acoustic Features & Driver Engineering
Dual-Stacked 135mm Ferrite Magnet Assembly
The foundation of this driver’s transient performance is its dual-stacked 135mm ferrite ring magnet engine. By creating a dense, highly focused magnetic field gap across the voice coil, the dual-magnet assembly keeps cone excursion linear and controlled during sudden dynamic peaks, preventing bottoming out or mechanical distortion.
High-Roll Rubber Surround with Green Accent Stitching
To manage long-stroke cone movement, the woofer incorporates an anti-aging rubber surround double-stitched directly into the cone matrix with high-tensile colored threading. This structural bonding prevents surround decoupling, dampens unwanted harmonic flex, and ensures long-term suspension endurance against heat and humidity.
Dual-Purpose Acoustic Design (Car Audio & Home Theater)
Unlike single-purpose car woofers that sound overly boomy indoors or home theater subwoofers that lack mechanical stiffness for car trunks, Model S-300 is tuned for broad acoustic adaptability. Its balanced mechanical parameters allow it to excel inside small automotive boot spaces as well as home living room acoustic setups.
Enclosure Compatibility & DIY Box Guidelines
This 12-inch driver adapts seamlessly to various custom enclosure volumes:
-
Sealed Enclosures (Tight, Accurate Acoustic Bass): Recommended for critical music listening and home studio setups where speed, punch, and flat frequency response are critical.
-
Ported / Vented Enclosures (Maximum SPL & Movie Bass): Recommended for high-output car audio or deep cinematic home theater low-end extension.
-
Amplification Matching: Pair with a mono-block power amplifier, bridged stereo amplifier, or home theater subwoofer plate amplifier delivering 200W to 350W RMS at 4 Ohms.

Frequently Asked Questions (FAQ)
Q1: Can I use this 12 inch 135mm double magnet subwoofer driver in both my car and home theater?
A: Yes. The motor structure and voice coil suspension parameters are engineered to perform efficiently in both sealed/ported car subwoofer boxes and custom residential home theater cabinets.
Q2: What is the advantage of a 135mm double magnet structure over a single magnet?
A: Double-stacked 135mm magnets generate higher magnetic flux density. This gives the motor better magnetic control over the voice coil, resulting in punchier bass, faster transient speed, and less distortion at higher volume levels.
Q3: What amplifier rating is best for driving this 12-inch woofer?
A: We recommend pairing this driver with an amplifier capable of outputting between 200W and 350W RMS at 4 Ohms.
