Many users appreciate the clear, well-balanced sound that this product delivers, especially at higher volumes. The soundstage is wider than expected, providing an immersive experience for casual listeners and audiophiles alike. Buyers also mention the smooth transition between mid-range and high frequencies, which makes the overall audio more pleasant and rich.
Some users report that the sound quality can be a bit too sharp for certain car environments. Specifically, those with smaller or more acoustically challenging spaces may feel that the highs are too pronounced, leading to slight discomfort at higher volumes. A few also note that tuning the speakers may require adjustments depending on the car's interior.
Bass Performance
92%
The bass response is one of the standout features of this audio upgrade. Users are consistently impressed with the depth and punch that these coaxial speakers provide, especially considering their size. Many note that the bass feels rich and full, even at mid-range volumes, which greatly enhances the overall listening experience in their vehicles.
However, a few users note that while the bass is deep, it can sometimes overwhelm the mid and high frequencies, leading to a somewhat unbalanced sound in certain setups. Those with more sensitive ears may find the bass-heavy performance distracting, especially during extended listening sessions. Additionally, some cars may require further adjustment to avoid muddiness.
Clarity of Highs

For users who value clear treble, the PEI balanced dome tweeter on these speakers is a highlight. Several reviews emphasize that the high frequencies come through crisp and clean, enhancing the overall clarity of vocals and instruments. These speakers shine particularly in acoustic music and genres that rely heavily on high-end details.
That said, not all buyers agree on the high-frequency clarity. Some find that while the highs are clear, they can also be a bit piercing at higher volumes. In certain cars, the tweeter may be too pronounced, leading to a harsh listening experience if not properly adjusted. Some users also mention that the treble lacks warmth, making it less suited for softer genres.

Installation is relatively straightforward for those familiar with car audio setups. The speakers come with a solid mounting frame, and many users report being able to complete the process without much hassle. The compact size makes them versatile for different car models, ensuring a good fit in many systems.
However, installation is not always a breeze for everyone. Some buyers mention that the instructions provided are sparse, which can be frustrating for first-timers. Additionally, certain cars may require additional adapters or modifications to ensure the speakers fit properly, leading to a more time-consuming setup than expected.

The overall build quality of these speakers is highly praised by users. The injection-molded polypropylene cone provides excellent durability, even in harsh conditions. Users also appreciate the sturdy construction of the vented basket frame, which contributes to better airflow and reduced distortion, making these speakers more reliable over time.
A few users have reported concerns with the outer frame being slightly less rigid than expected.
