PSB Alpha P3 - Bookshelf Speakers -

The Alpha P3 is a small two-way bookshelf speaker that brings hifi pedigree to your stereo or home theatre system to fill the room with crystal-clear sound. Featuring a custom 4” (102mm) woofer and aluminium dome tweeter that uses a waveguide to perfectly match the low and high frequencies for a smooth transition, the P3 delivers natural sound, at an affordable price. It also leverages specially textured woofer cones and a unique port tube design to add back energy and extend the bass frequencies even lower without any distortion.
