The SB Acoustics SB15BAC30-8-COAX is a 5-inch coaxial driver designed for high-fidelity audio applications where accuracy, clarity, and compactness matter. Featuring a robust aluminum cone woofer and a soft dome tweeter integrated concentrically, this driver is engineered for seamless frequency response and superior sound directivity, making it a versatile choice for both home and custom speaker building projects.
SB Acoustics SB15BAC30-8-COAX 5" Coaxial Woofer & Tweeter 8 Ohm
This coaxial driver combines a 5-inch woofer and a 19 mm soft dome tweeter, both engineered for precise sonic reproduction. The woofer utilizes a geometrically reinforced aluminum cone, which not only enhances rigidity but also suppresses unwanted resonances, resulting in clear and natural midrange. The low profile rubber surround ensures minimal diffraction, allowing for a cleaner integration with the tweeter and smoother high-frequency dispersion.
The tweeter, positioned at the acoustic center of the woofer, features a lightweight CCAW voice coil on a fiberglass former, paired with a neodymium motor and center cavity for increased efficiency and lower distortion. This design enables excellent control over high-frequency directivity and delivers crisp, detailed treble, making it an ideal solution for tweeter upgrades or new loudspeaker builds where imaging and clarity are priorities.
Designed with versatility in mind, the SB15BAC30-8-COAX excels in a range of speaker configurations, from compact two-way monitors to multi-way systems. Its vented cast aluminum chassis supports robust airflow and cooling, while the extended copper sleeve on the pole piece ensures low inductance and distortion for transparent playback. With a nominal impedance of 8 ohms for the woofer and 4 ohms for the tweeter, this driver is compatible with a wide array of modern amplifiers.
For DIY enthusiasts and custom audio designers, the SB15BAC30-8-COAX offers flexibility in cabinet design and crossover integration. The carefully engineered Thiele/Small parameters, including a 43 Hz free air resonance and 86 dB sensitivity for the woofer, allow for precise tuning in various enclosures. Its compact form factor and integrated design also make it a great fit for DIY speaker kit projects where performance and ease of assembly are important.
