Update: PSB Alpha PS1 Bookshelf Speakers
The Alpha PS1s are PSB's first powered speakers, and are bookshelf in size. Driven by built-in Class D amplifiers, they feature 3.5" metalized polypropylene main drivers and 0.75" aluminum dome tweeters in elegant ported enclosures. These speakers are the latest member of PSB's Alpha line which has been very popular and well received by the audio press and consumers alike. Late last year, PSB announced they would be releasing a super compact powered subwoofer. This new sub was designed to go along with PSB's incredible little PSB Alpha PS1 ($299) desktop speakers that I reviewed in July 2013. So I promptly requested a review sample as I wanted to write this quick follow-up to my earlier review.
