AudioCircle SL-C6.2 – 165 mm Separate Speaker Set
AudioCircle SL-C6.2 is a 2-way car separate speaker set with 165 mm mid-woofers. This model belongs to the Stuttgart Line series by the German brand AudioCircle.
Stuttgart Line is the entry-level AudioCircle speaker series, designed for easy installation and a significant improvement in sound over many factory audio systems. The set works well with car stereos, as well as with external amplifiers of moderate power.
Stuttgart Line – simple installation and solid materials
AudioCircle SL-C6.2 is perfect for users who want to replace their standard speakers with a better, durable, and easy-to-install separate set. The 165 mm DIN mid-woofers fit many standard car mounting locations.
The mid-woofer membranes are made of polypropylene, while the upper suspension is made of rubber. This combination ensures good resistance to the working conditions in car doors and stable sound for a long time.

20 mm silk dome tweeters
20 mm silk dome tweeters are responsible for the high frequencies. The silk dome provides a pleasant, smooth, and detailed top-end sound.
An additional acoustic diffuser helps improve the high-frequency response in the car. This allows for a more spacious and less point-like sound, especially when mounting the tweeters in their factory locations.
165 mm Mid-woofers with a polypropylene cone
The mid-woofers have a diameter of 165 mm and use a polypropylene cone. This material is valued for its durability, resistance, and stable operation in automotive environments.
The mid-woofers are responsible for the midrange, lower frequency range, and the foundation of the entire system's sound. The rubber upper suspension supports the proper operation of the cone and helps maintain good sound control during everyday listening.
The steel basket in the DIN 165 mm standard facilitates installation in many cars. Additionally, a rubber cover on the magnetic system protects the magnet from mechanical damage and corrosion.
3.2 Ohm Impedance – Good Interaction with Radio
The system's impedance is 3.2 Ohm. This allows the speakers to work effectively with low-power factory car stereos.
The AudioCircle SL-C6.2 can be used as a simple upgrade to the factory audio system. However, when connected to an external amplifier, the system can offer better control and greater dynamics.
In-line crossovers for tweeters
The set includes two passive in-line crossovers. They act as 12 dB/oct HP filters for the tweeters.
The crossovers protect the tweeters from excessively low frequencies and help achieve proper frequency response. Their compact design facilitates installation in the car.

Important installation information
Before purchasing, it's worth checking the diameter of the mounting location and the mounting depth in your car. Mid-woofers require a mounting depth of 62 mm.
Tweeters should be connected via the in-line crossovers included in the kit. Proper high-frequency filtering is important for the sound quality and safety of the tweeters.
When mounting mid-woofers in the doors, it's worth using solid spacers and soundproofing. This will allow the system to better utilize its potential.
