Combining the latest QR series, QR9 series, along with Tweeter and amplifier to enhance sound performance
If you have higher demands for car audio, considering the QR series would be an excellent choice. These speakers stand out in performance and are affordably priced, offering you an exceptional sound experience.
The power range of QR series speakers extends from the QR422's 30W/75W to the QR693's 60W/150W RMS/Peak Power (Each), with an SPL range between 87dB to 90dB. Compared to factory speakers, the QR series significantly enhances both sound quality and volume and can be safely connected with your car's original stereo or amplifier.
Just find the speaker size that matches your vehicle, without changing any original wiring or amplifier, you can quickly enhance the sound quality of your car audio system.
The QR series offers a complete range of sizes: 4", 5-1/4", 6-1/2", 6-3/4", and 6"x9", making them suitable for upgrading various types of vehicles.
Coaxial and triaxial designs place different audio frequencies on separate speaker units, letting each focus on specific frequencies for a more pure and separated sound.
If you have higher requirements for sound quality, the QR9 series would be your ideal choice. Compared to the QR series, the QR9 series has a larger magnetic circuit and a higher grade of Voice Coil material, making the music sound more solid and powerful; more durable drum paper and edge material also allow your speaker to better resist various adverse environments of low and high temperatures and humidity.
The QR9 series also includes a Component Kit design, including a 6-1/2” Woofer, Cross Over, and Tweeter, allowing you to arrange the bass and treble in the most appropriate positions to achieve a better sound field.
Whether it's the QR series or the QR9 series, coupling them with an amplifier specifically designed for these speakers can provide more powerful driving power.
In addition, introducing high-pitched speakers, such as Tweeters, is also a good choice. Tweeters can clearly play high-frequency audio, allowing the details of the music to be fully displayed, thereby providing a more comprehensive audio experience.
By arranging the Tweeter on the A-pillar or other suitable locations, high notes can surround the entire environment while enjoying music, enhancing the spatial sense of music.
If you want to further enhance the sound effect, consider upgrading your existing amplifier. A quality amplifier can provide more driving power to the speakers, improving the overall performance of the audio.
Paired with the QR or QR9 series' dedicated amplifier, its powerful output power and excellent sound quality elevate your car audio system to a new level, as if you owned a personal luxury music hall.
Finally, if you want your car audio to be more unique, the unique design of the QR series and the larger RMS and Peak Power of the QR9 series, enabling your audio to handle larger amplifier power outputs, producing larger and undistorted sound quality, are good choices.
In conclusion, whether it's the QR series or the QR9 series, along with the combination of Tweeter and a dedicated amplifier, all can effectively enhance your car audio performance and sound quality, filling every moment of driving with captivating melodies and musical enjoyment.
