The Alpha P5 delivers an even more robust and controlled bass than the Alpha P3  Bookshelf Speaker , thanks to a custom-designed 5.25" woofer and smart engineering. The woofer, crafted from textured polypropylene with a rubber surround and dual-layer voice coil, minimizes distortion and provides deep, impactful bass. Combined with a rear-firing port tube, the P5's bass response is extended to size-defying levels while maintaining precision and tightness for an immersive listening experience.
