Pioneer TS-G170C 17 cm Component G Series 2 Way Speakers Review: A Long-Term User’s Perspective

Remember the frustration of driving your car, only to be met with flat, lifeless audio emanating from your factory speakers? It’s a common issue, and one that consistently left me yearning for a richer sound experience. The tinny highs and non-existent bass truly took away from the enjoyment of my favourite tracks. This pervasive problem needed a real solution, as continued listening to such poor quality audio simply detracted from every journey, making long drives less enjoyable and everyday commutes more mundane. Upgrading to a quality set of component speakers would have made all the difference.

Choosing Your Next Car Audio Upgrade: What to Consider

Many of us spend a considerable amount of time in our cars, making the in-car audio system a crucial part of the driving experience. A poor sound system can diminish everything from daily commutes to epic road trips, leaving music sounding dull and uninspired. This is precisely why one would seek to upgrade their car’s audio. The ideal customer for an audio upgrade like the Pioneer TS-G170C is someone looking for a significant improvement over their factory setup without breaking the bank. They likely appreciate clear vocals, well-defined mid-range, and a noticeable upgrade in overall sound quality, and are perhaps comfortable with a bit of DIY installation or willing to have a professional handle it.

However, this product category might not be for everyone. If you’re an extreme audiophile demanding competition-level sound pressure or earth-shattering bass that rattles the windows, a basic component set like this, without the addition of a dedicated amplifier and subwoofer, won’t fully satisfy those specific needs. In that case, you’d be looking at a more complex, multi-component system with separate amplifiers, digital sound processors, and a robust subwoofer enclosure. Before making any purchase, prospective buyers should consider several factors: the speaker size that fits their vehicle, whether they want coaxial (all-in-one) or component (separate woofer and tweeter) speakers for better sound staging, the RMS power handling of the speakers compared to their head unit’s output (or an aftermarket amplifier), and their budget for both the speakers and potential installation costs. Thinking about these elements will help ensure you choose the right upgrade for your specific audio aspirations.

Introducing the Pioneer TS-G170C

The Pioneer TS-G170C 17 cm Component G Series 2 Way Speakers with Separate Tweeters are designed to breathe new life into your car’s audio system. This component speaker set promises a clearer, more dynamic sound than standard factory speakers, delivering an immersive listening experience. When you purchase this package, you receive a pair of 17 cm woofers, two separate tweeters, and the necessary mounting hardware, including grills, making it a comprehensive solution for a front or rear stage upgrade. Compared to many basic aftermarket options, the G Series offers a balance of quality and affordability. While it might not compete with Pioneer’s higher-end P.R.S. series or dedicated audiophile brands in terms of raw power or ultimate fidelity, it offers a significant step up from standard factory offerings and even many coaxial speakers at a similar price point due to its component design.

These particular Pioneer speakers are ideal for individuals who want to enhance their vehicle’s sound without extensive modifications or a hefty investment. They are perfect for upgrading existing 17 cm (or compatible) speaker locations and for those who appreciate the improved imaging that separate tweeters provide. They are not, however, for someone seeking to build a competition-level sound system or those who demand extremely deep, earth-shaking bass without the aid of a dedicated subwoofer.

Pros:
* Significantly improved clarity and detail over factory speakers.
* Component design allows for better sound staging with separate tweeters.
* Good power handling (300W Max / 45W RMS) for a budget-friendly option.
* Well-defined mid-range and punchy, clear bass (for their size).
* Excellent value for money, a noticeable upgrade without a premium price tag.

Cons:
* Bass, while clear, doesn’t reach very low frequencies without a subwoofer.
* Tweeters can be a bit sharp or harsh at higher volumes, potentially requiring EQ adjustment.
* Installation might require minor customisation for the separate tweeters and crossovers.
* Some users reported missing sealing tape, a minor inconvenience during installation.
* Not suitable for those expecting deep, rumbling bass without additional amplification or a subwoofer.

In-Depth Look: Features & Performance

Having spent a considerable amount of time with the Pioneer TS-G170C component speakers, I can confidently delve into the nuances of their features and how they translate into a tangible listening experience. My goal with these speakers was to achieve a balanced, enjoyable sound in my car, far superior to the stock setup.

Power Handling and Output: Driving Clearer Sound

One of the first things that stands out about the Pioneer TS-G170C is its power handling capabilities. Rated at 300 Watts Max power and 45 Watts RMS (Nominal) power, these speakers are designed to handle a decent amount of input. In practical terms, this means they can cope with the output from most aftermarket head units comfortably, and even a modest external amplifier, without easily distorting. My experience has been that they perform exceptionally well when driven by a quality aftermarket head unit, delivering crisp and clean sound even at higher volumes. The 45 Watts RMS rating is particularly important, as it represents the continuous power the speaker can handle. This ensures that you get consistent, reliable performance for everyday listening, rather than just momentary peaks. This capability helps in preventing the sound from becoming muddy or breaking up when you push the volume, which is a common issue with lower-quality or underpowered speakers. The benefit here is a sound that remains clear and enjoyable across a wider range of volumes, allowing you to truly immerse yourself in your music without worrying about distortion.

IMPP Composite Cone Woofers: The Foundation of Good Bass

The woofers in the Pioneer TS-G170C utilise an Injection Moulded Polypropylene (IMPP) composite cone. This material choice is crucial for speaker performance. IMPP cones are known for their rigidity and light weight, which allows them to respond quickly and accurately to audio signals. This rigidity helps in preventing cone flex, which can cause distortion, especially in the mid-bass frequencies. What I’ve consistently noticed is the impressive clarity these cones bring to the mid-range and upper bass. Instruments like kick drums and bass guitars come through with a satisfying punch, rather than a boomy, undefined thud.

While the bass isn’t “subwoofer-deep” – a common characteristic of most full-range or component speakers not paired with a dedicated sub – it is remarkably well-defined and articulate for a 17 cm speaker. This clarity means you can discern individual bass notes and textures, rather than a generic rumble. For genres like rock, pop, and electronic music, where clear, punchy bass is essential, these woofers deliver. The benefit is a more engaging and dynamic listening experience, where the low-end complements the rest of the sound spectrum without overpowering it or becoming a muddy mess. It provides a solid foundation for your music, making tracks sound fuller and more impactful than through stock car speakers.

Separate Tweeters: Precision High-Frequency Delivery

One of the most significant advantages of component speakers like the TS-G170C is the inclusion of separate tweeters. Unlike coaxial speakers where the tweeter is mounted in the centre of the woofer, separate tweeters can be mounted independently, typically higher up in the car’s interior (e.g., A-pillars or door panels). This allows for much better sound staging and imaging. By positioning the tweeters closer to ear level, the high frequencies sound like they are coming from the dashboard rather than from your feet, creating a more realistic and immersive soundstage. The result is a richer, more detailed high-end. Vocals sound incredibly crisp, cymbals shimmer with precision, and acoustic guitar strings resonate clearly.

However, it’s worth noting that, like some users, I found the tweeters could be a touch sharp or “bright” at higher volumes, particularly if the source material was already on the brighter side or if the head unit’s EQ was set aggressively. This isn’t necessarily a flaw of the speaker itself, but rather a characteristic that might require some fine-tuning with your head unit’s equaliser settings. A slight attenuation of the treble or adjusting the EQ curve can easily mitigate this. The benefit of these separate tweeters is undeniable: they elevate the listening experience by providing a level of detail and spatial separation that simply isn’t possible with most coaxial or factory speakers, making your music truly come alive in the car.

Wide Frequency Response: Hearing the Full Spectrum

The Pioneer TS-G170C boasts a frequency response range of 44 – 25,000 Hz. This wide range indicates the breadth of sounds the speakers are capable of reproducing, from the lower mid-bass tones right up to the very highest frequencies audible to the human ear. A broad frequency response is essential for a complete and natural-sounding audio experience. Without it, music can sound thin, lacking in detail at the extremes, or overly focused on a narrow band of frequencies.

In practice, this means the speakers don’t just reproduce the vocals and mid-range instruments effectively; they also handle the nuances of percussion, the subtleties of synth pads, and the airy quality of string instruments. The low end, starting at 44 Hz, ensures that you get a respectable amount of mid-bass presence, giving body to your music even without a dedicated subwoofer. On the other high end, extending to 25,000 Hz means that even the most delicate high-frequency details, like the shimmer of a hi-hat or the harmonics of an acoustic guitar, are rendered accurately. The benefit is a much richer, more complete audio experience, where you hear more of your music the way it was intended, with all its layers and textures intact.

Design and Build Quality: Durability Meets Aesthetics

From a build quality perspective, the Pioneer TS-G170C feels robust. Constructed from a combination of plastic and metal, these speakers strike a good balance between durability and weight. The woofers feature sturdy baskets, which are important for minimising resonance and ensuring reliable performance over time. The included grills are a nice touch, offering protection for the cones while also providing a neat, finished look if your car’s interior allows for their use.

My long-term observation confirms that these Pioneer speakers are built to last under typical automotive conditions. They withstand temperature fluctuations and the general vibrations associated with driving without any issues. The aesthetic design is understated yet functional, fitting well into various car interiors. The benefit here is peace of mind, knowing that your investment in improved car audio will endure for years to come, providing consistent performance and maintaining its appearance.

Installation and Compatibility: Getting Them in Your Ride

The 17 cm size of these Pioneer TS-G170C speakers makes them a popular choice for direct replacement in many European and Asian vehicles that use this common speaker diameter. For me, the installation was relatively straightforward, although it did involve a bit more work than a simple coaxial swap due to the separate tweeters and passive crossovers. Pioneer includes screws and some wiring, and crucially, the packaging itself can be used as a template for cutting speaker rings or adapters if needed, which I found incredibly useful. While not explicitly mentioned in the official description as “wall mount,” the implied “mounting type” for car speakers refers to their fitment within door panels or other car speaker locations.

The process of running new wires for the tweeters and finding suitable mounting spots for them (and the small passive crossovers) adds a layer of complexity, but it’s entirely manageable for anyone with basic DIY car audio experience. The benefit of this slightly more involved installation is a vastly superior soundstage. The ability to place the tweeters optimally for your listening position dramatically improves the stereo image, making music sound more open and as if the sound originates from further in front of you, rather than from below. This flexibility in placement is a core advantage of component systems, allowing for a tailored audio experience that truly maximises the potential of these Pioneer speakers.

Voices from the Road: Community Feedback

Having delved into my own extensive experience, I also scoured the internet for what other users thought about the Pioneer TS-G170C, and the general sentiment is overwhelmingly positive. Many users echo my findings, praising the significant upgrade these speakers provide over standard factory units, particularly highlighting the improved clarity and strong bass output for their size. One Audi A4 owner mentioned they looked great and provided excellent sound for a DIY arcade cabinet, requiring minimal amplifier power. Another user from Germany noted the first-class performance for the price, though they observed the lack of sealing tape. A BMW E46 Compact owner was genuinely surprised by the powerful lows and pleasing tweeters, citing the excellent value and build quality. Even with minor criticisms regarding the tweeters’ sharpness at high volumes or the bass not reaching the absolute lowest frequencies, the consensus points to these Pioneer speakers as a fantastic choice for a budget-conscious audio upgrade.
