Boxe PSB Alpha B1 bookshelf

Aceasta a fost prima pereche de boxe PSB pe care am cumparat-o. Başii redaţi surprinzător de clar şi de dinamic având in vedere dimensiunile compact se evidentiala de la prima auditie. Le am si acum imperecheate cu un amplificator NAD C 316BEE.

    For decades, the Alpha B1 has been trusted by audio experts as the reference model for monitor speakers, making it one of the most reviewed bookshelf speakers ever. Starting from scratch at Canada’s national acoustic labs, the Alpha B1 is a true two-way design that uses a 5¼” (133mm) woofer made of metalized polypropylene, paired with a ¾” (19mm) aluminium dome tweeter to deliver crisp full-range sound with accurate and detailed bass. It uses the Alpha Series’ patented bass reflex design that utilizes the rear-firing port tube to improve efficiency and bring the bass response down below 60Hz.
