Update: PSB Alpha PS1 Bookshelf Speakers


Best of 2013 Awards

Introduction to the PSB Alpha PS1 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. This information is now on the last page of this review - See Update in ARTICLE INDEX on the upper right side of this page.)

PSB speakers celebrated their 40th Anniversary in 2012. This means they have a 40-year history of producing high quality loudspeakers of all kinds. PSB's marketing byline is "Real Sound for Real People". I personally find this to be apropos based on my first hand experience with PSB speakers: their speakers are high quality, affordable, accessible and have positive audible traits that everyday listeners can enjoy. The big question is, "Will the Alpha PS1s be able to sustain the family's image?" Go to Page 2: Design and Setup
