Tunex Zen 12" 1000rms Subwoofer TX1210-D4

TUNEX ZEN 12 TX 1210D4 DUAL 4 OHM SUBWOOFER

DEEP BASS. CLEAN PERFORMANCE. BUILT FOR EVERYDAY SYSTEMS.

The Tunex ZEN 12 TX 1210D4 is designed for car audio enthusiasts who want a strong bass upgrade without needing an extreme competition style system.

With a 12 inch cone, Dual 4 Ohm copper voice coil, high grade Y35 ferrite magnet, Tunex tuned suspension and ±13 mm Xmax, the ZEN 12 delivers the low frequency impact that factory audio systems are often missing.

Whether you are upgrading your daily driver or building your first proper subwoofer system, the ZEN 12 gives you a balance of deep bass, controlled performance, durability and value.

A PROPER BASS UPGRADE WITHOUT MAKING THE SYSTEM OVERCOMPLICATED.

WHY CHOOSE THE ZEN 12?

Not everybody needs the biggest subwoofer or the highest powered system.

For many vehicles, a properly designed 12 inch subwoofer system gives an excellent balance between bass output, enclosure size and everyday usability.

The ZEN 12 is designed for customers who want:

• Deep and powerful bass

• More impact than factory audio

• Clean everyday performance

• Flexible amplifier wiring options

• Strong cone movement

• Reliable construction

• Excellent value for money

• A system that is enjoyable every day

MORE BASS. MORE IMPACT. WITHOUT NEEDING AN EXTREME BUILD.

12 INCH BASS FOR EVERYDAY LISTENING

A good 12 inch subwoofer is one of the most versatile ways to add serious low frequency performance to a vehicle.

The TX 1210D4 provides approximately 475.35 cm² of effective cone area and ±13 mm of linear excursion, giving it the ability to move considerably more air than other subwoofers.

For you, that means:

• Stronger bass lines

• Harder hitting kick drums

• More low frequency depth

• More physical impact

• A fuller sounding audio system

Instead of turning your factory speakers up harder trying to create bass they were never designed to produce, let a dedicated subwoofer handle the low frequencies properly.

±13 MM XMAX

Bass requires air movement.

The TX 1210D4 has a maximum linear excursion of ±13 mm, allowing the cone to move substantially while reproducing low frequencies.

That excursion works together with the 12 inch cone area to give the ZEN 12 strong bass capability when installed in the correct enclosure.

MORE CONTROLLED AIR MOVEMENT MEANS MORE BASS YOU CAN FEEL.

DUAL 4 OHM VOICE COIL

The ZEN 12 uses a Dual 4 Ohm copper voice coil configuration.

This gives you useful flexibility when matching the subwoofer to an amplifier.

A single TX 1210D4 can be wired to:

2 Ohm Parallel

or

8 Ohm Series

For most single subwoofer car audio applications, the 2 Ohm configuration can be useful when matching the subwoofer with a compatible mono amplifier.

Always check the amplifier's impedance capability before connecting the subwoofer.

CORRECT IMPEDANCE MATCHING HELPS YOU GET THE RIGHT PERFORMANCE SAFELY.

COPPER DUAL VOICE COIL

The TX 1210D4 uses a copper dual voice coil designed for reliable electrical performance.

The voice coil forms an important part of the subwoofer's motor system and works with the magnet and suspension to control the movement of the cone.

Correct amplifier matching, gain setting and enclosure design all help the voice coil and subwoofer perform as intended.

HIGH GRADE FERRITE MAGNET

The ZEN 12 uses a high grade ferrite magnet as part of its motor structure.

The motor provides the force required to drive and control the moving assembly during demanding bass playback.

Combined with the copper voice coil and tuned suspension, it gives the ZEN 12 the foundation required for strong everyday low frequency performance.

TUNEX TUNED SUSPENSION

A subwoofer should not simply move.

It needs to move with control.

The ZEN 12 uses a Tunex tuned suspension system designed to support the moving assembly and maintain consistent cone behaviour.

This helps provide the balance between:

Output

Control

Sound quality

Reliability

The result is bass designed to sound powerful without simply becoming loose or uncontrolled.

RIBBED FOAM SURROUND

The ribbed foam surround provides the flexibility required for the cone to move through demanding low frequency passages.

It works together with the suspension system to help maintain cone control as excursion increases.

DUAL TENSILE LEADS

The TX 1210D4 uses dual tensile leads to provide a durable electrical connection to the moving voice coil assembly.

This is important because the leads repeatedly move with the cone during bass playback.

Strong construction helps support reliable performance during real world use.

BUILT FOR REAL WORLD CAR AUDIO

The ZEN 12 is a great choice for:

• Daily driver bass systems

• Factory audio upgrades

• First car audio builds

• Single 12 inch subwoofer systems

• Dual 12 inch systems

• Budget conscious enthusiasts

• Customers wanting more bass without sacrificing excessive boot space

• Performance focused everyday systems

GOOD BASS DOES NOT HAVE TO MEAN AN EXTREME SYSTEM.

THE ENCLOSURE MAKES A BIG DIFFERENCE

Putting a good subwoofer into the wrong enclosure can leave a lot of performance on the table.

The enclosure affects:

• How deep the bass plays

• Overall output

• Cone control

• Bass character

• Sound quality

• How the subwoofer responds across different frequencies

The ZEN 12 should be installed in an enclosure designed around the subwoofer and the type of bass you want.

Some customers want deep and smooth bass.

Others want harder hitting and louder bass.

The enclosure should be designed accordingly.

DO NOT CHOOSE A BOX JUST BECAUSE THE SUBWOOFER FITS INSIDE IT.
