The Gladen Alpha 10 SB is an enclosed car subwoofer designed to add depth and richness to your vehicle's audio system. It features a 250 mm driver with a scooped paper diffuser and a 3D PP dust cap, all supported by a sturdy steel basket and a Nomex spider for stability. This setup allows the unit to handle power between 150 and 250 W with a 4 Ohm impedance. Its closed box design occupies a volume of 22 L and has a depth of 34 cm, making it a compact choice for those who want a balanced bass response without sacrificing too much trunk space. With a resonance frequency of 37 Hz, a sensitivity of 87 dB, and an Xmax of 3.5 mm, it provides a controlled and precise low-end performance that suits listeners who prefer a clean, tight sound over overwhelming volume.
