The 8" mid-bass drivers are 20 cm in diameter and the 1" tweeters measure 25 mm. Installation in the vehicle is straightforward as long as the existing speaker cutouts support these dimensions. Since no specific car brands are noteworthy, you should ensure before purchasing that your existing systems have universal mounting openings for such speaker sizes to ensure a smooth installation.
The Ref 8 - 2WAY speaker set from B2 Audio uses high-quality materials for its components. The 1" tweeters are equipped with neodymium magnets that provide high magnetic performance in a small space, while the 8" woofers use strontium magnets to ensure strong and even attraction. This selection of materials is crucial to ensure the high sound quality and performance range of the system. The combination of robust magnet types with solid voice coils and cabinet constructions ensures long-lasting performance and audio integrity.
In addition to the impressive sound range and performance configuration of the Ref 8 - 2WAY speaker set, it also offers additional technical features. The Thiele-Small parameters such as QMS, QES, and QTS provide deep insights into the mechanical and electrical behavior of the system. The VAS value is 21 liters for the mid-bass drivers, which is an indicator of the volume of air that the speaker can displace, while the BL value of 14 shows how strong the magnetic force is. These parameters are crucial for a detailed understanding of the performance and efficiency of the speaker system.
The installation of the Ref 8 - 2WAY speaker set from B2 Audio is a well-thought-out process thanks to the components included in the set. The two supplied 2-way crossovers ensure that the correct frequencies are efficiently distributed to the tweeters and woofers. Before mounting, you should check whether the placement of the speakers is optimal for the acoustic experience and that the mid-bass drivers fit properly into the designated cutouts. With the right calibration, frequency corridors can be optimized to fully exploit the auditory potential of the system.
The Ref 8 - 2WAY System from B2 Audio features voice coils with different diameters. For the 8" mid-bass drivers, the voice coil diameter is 2 inches (approximately 5 cm), while the 1" dome tweeters have a voice coil diameter of 1 inch (approximately 2.5 cm). These measurements are crucial, as the size of the voice coil affects the load capacity, thermal handling, and ultimately the sound fidelity of the speaker. The sizing is therefore optimized to ensure both efficient performance and durability in demanding audio scenarios.
The resonance frequencies of the two main components of the Ref 8 - 2WAY speaker set are crucial parameters that define the sound behavior. The 8" woofers have a resonance frequency (FS) of 45 Hz, making them ideal for the lower frequency ranges. In contrast, the 1" dome tweeters have a resonance frequency of 1250 Hz, which optimizes them for high-frequency audio content. These differentiated resonance frequencies ensure that each component efficiently covers its specific frequency range, thereby providing a balanced sound image.
