Product Overview
Factory dash speakers have a major influence on what you hear from the driver's seat.
Because they're mounted high in the vehicle and relatively close to ear level, they can play an important role in vocal clarity, instrument detail, high-frequency presence, and overall soundstage height.
The DS18 PRO-ST takes advantage of those factory locations with a high-efficiency compression tweeter built into a mounting assembly designed specifically for many Toyota and Subaru applications.
Rather than purchasing a universal tweeter and fabricating a bracket to make it fit, the PRO-ST is designed to bolt into compatible factory speaker locations.
That gives you the benefits of a high-output aftermarket tweeter with a much cleaner installation approach.
98 dB Sensitivity – Big Output from a Small Speaker
One of the standout specifications of the PRO-ST is its 98 dB sensitivity rating.
Higher sensitivity allows a speaker to produce more output from a given amount of amplifier power, which is particularly valuable in a small factory dash location.
That makes the PRO-ST an interesting option for compatible systems using factory amplification or a head unit, while still providing the power handling needed for properly designed aftermarket systems.
The goal isn't bass—the PRO-ST is built to reproduce the frequencies responsible for clarity, presence, vocals, cymbals, and high-frequency musical detail.
Neodymium Compression Tweeter Design
At the heart of the PRO-ST is a compact 1-inch compression tweeter.
Neodymium Magnet
A lightweight, powerful neodymium motor helps provide high efficiency while keeping the overall assembly compact enough for space-restricted factory locations.
PEN Diaphragm
The PEN diaphragm is designed for responsive high-frequency reproduction and clear musical detail.
1" CCAW Voice Coil
The tweeter uses a 1-inch CCAW voice coil wound on a Kapton former for a combination of lightweight construction and thermal capability.
Together, these components allow the PRO-ST to deliver the aggressive clarity and projection associated with DS18's PRO Audio products from an OEM-style speaker location.

BRZ / FR-S / 86 Applications
DS18 also notes that Scion BRZ and Toyota FR-S / 86 applications can replace the factory 3.5-inch midrange and 1-inch tweeter configuration with the PRO-ST.
Always verify your specific vehicle, trim level, factory audio package, mounting location, and wiring before ordering.
OEM-Style Mounting Without Universal Tweeter Fabrication
The mounting design is one of the biggest reasons to choose the PRO-ST.
The complete assembly measures approximately only 1.33" of mounting depth, allowing it to bolt into many of the compatible factory Toyota and Subaru locations listed above.
This can eliminate the need to fabricate a custom mounting plate simply to secure an aftermarket tweeter.
Wiring requirements may vary by vehicle and factory audio system. We recommend verifying the factory connector before installation rather than assuming every application will provide a completely plug-and-play electrical connection.
Recommended 4kHz High-Pass Crossover
DS18 recommends a 4kHz high-pass crossover for the PRO-ST.
This is important.
The PRO-ST is a dedicated tweeter—not a 3.5-inch full-range or midrange speaker. It should be protected from lower frequencies so it can concentrate on the high-frequency information it was designed to reproduce.
When building an actively amplified system, proper crossover configuration is essential for both performance and reliability.

Will These Fit My Vehicle?
The DS18 PRO-ST is designed for select Toyota and Subaru applications, but vehicle-specific audio systems can vary by trim level, model year, and factory sound package.
Before ordering, verify:
-
Vehicle year, make, and model
-
Factory speaker location
-
Factory audio package
-
Factory speaker impedance
-
Available mounting depth
-
Wiring connector style
-
Whether your vehicle uses a factory amplifier
The PRO-ST uses a vehicle-specific mounting design intended to simplify installation in many supported Toyota and Subaru locations.
Wiring requirements can vary by application, so do not assume every installation will be completely plug-and-play electrically.
Factory Radio or Aftermarket Amplifier?
The PRO-ST is a high-efficiency 4-ohm compression tweeter, which makes it versatile for a variety of compatible systems.
Factory Radio Systems
Its 98 dB sensitivity allows the PRO-ST to produce strong output from relatively modest power.
However, factory systems can use unusual impedance, equalization, crossovers, and amplifier configurations.
Always verify that the PRO-ST's 4-ohm impedance is appropriate for your specific factory system.
Factory Amplified Systems
Toyota JBL®, Subaru premium audio systems, and other factory amplified setups may use dedicated crossover networks, DSP processing, or non-standard speaker impedance.
The PRO-ST can be an excellent upgrade in the right application, but factory amplified systems should be evaluated carefully before replacement.
Aftermarket Amplified Systems
The PRO-ST is especially well suited for custom systems where crossover frequency and amplifier output can be properly controlled.
For best performance, use clean amplifier power and follow DS18's recommended high-pass crossover.
Recommended Crossover Setup
DS18 recommends a 4kHz high-pass crossover for the PRO-ST.
Recommended Starting Point
High-Pass Filter: 4kHz
This helps prevent lower-frequency energy from reaching the tweeter and allows it to concentrate on the upper frequencies it was designed to reproduce.
Proper crossover setup is especially important when using aftermarket amplification.
Do not run the PRO-ST full-range.
Popular Upgrade Applications
Toyota Tacoma Dash Upgrade
The Tacoma is one of the most popular applications for the PRO-ST.
Upgrading the factory dash location can bring vocals and upper-frequency detail forward while maintaining a clean OEM-style mounting location.
Toyota 4Runner Audio Upgrade
For 4Runner owners building a stronger front stage, the PRO-ST provides a high-efficiency solution for compatible factory dash locations.
It pairs especially well with upgraded front door speakers and properly tuned amplification.
Toyota Tundra & Sequoia
These larger vehicles can benefit from additional high-frequency presence, especially in systems using upgraded door speakers and amplifiers.
The PRO-ST helps create a more energetic front soundstage without requiring custom tweeter fabrication.
Subaru WRX / STI / Forester / Crosstrek
Subaru owners looking to improve upper-frequency clarity can use the PRO-ST in compatible factory locations while maintaining a clean installation.
Installation Notes
Before installation:
-
Verify your exact vehicle application.
-
Confirm factory speaker impedance.
-
Confirm available mounting depth.
-
Check factory connector style.
-
Determine whether wiring adapters or termination changes are required.
-
Observe correct speaker polarity.
-
Use the recommended high-pass crossover.
-
Test the system before reinstalling factory trim panels.
Because the PRO-ST is a dedicated tweeter, crossover protection should be treated as a requirement rather than an optional tuning step.
Pro Audio Center Tip
A common mistake with dash tweeter upgrades is assuming louder automatically means better.
The goal should be better balance.
The PRO-ST is very efficient, so it can add significant high-frequency presence to a system. That is a major advantage, but it also means careful tuning matters.
If the tweeters are too dominant, vocals can sound overly forward or fatiguing. Proper crossover, amplifier gain, and overall front-stage tuning help the PRO-ST blend naturally with the rest of the system.
Complete Your Front Stage
Depending on your vehicle and system goals, consider pairing the PRO-ST with:
-
Upgraded front door speakers
-
Component or midbass speakers
-
Multi-channel amplifier
-
DSP or signal processor
-
Vehicle-specific speaker harnesses
-
Sound deadening
-
OFC speaker wire
-
Dedicated subwoofer system
A well-balanced front stage typically performs best when the tweeters, door speakers, amplifier, and crossover settings are planned together.
Expert Recommendation from Pro Audio Center
The DS18 PRO-ST is a strong option for Toyota and Subaru owners who want a more aggressive, high-output front soundstage without fabricating custom tweeter mounts.
What makes it especially useful is the combination of:
-
Vehicle-specific mounting
-
98 dB sensitivity
-
4-ohm impedance
-
Compact neodymium motor
-
Dedicated compression tweeter design
We especially like it for customers upgrading the rest of the front stage at the same time.
If you're keeping an entirely stock audio system, take extra care to verify factory impedance and crossover behavior. If you're building an amplified system with proper tuning control, the PRO-ST becomes an even stronger option.
