Audioengine Announces Audioengine P4

DALLAS, TX - June 25, 2009 - Audioengine today announced the release of the Audioengine P4 Premium Passive Bookshelf Speakers.

The Audioengine P4 (AP4) is a high-performance bookshelf speaker pair with the same great looks and sound as Audioengine’s award-winning powered speakers. Beautiful, small, and affordable, AP4 is the perfect choice for your living room, bedroom or office and an ideal surround speaker for use with other Audioengine speakers in your home theater or stereo system.

“The goal was to design a small but powerful bookshelf speaker for people that already have receivers or amps and are looking for the same Audioengine sound and quality in a passive loudspeaker." explained Dave Evans, Audioengine co-founder. “The AP4’s work great with Class D desktop amplifiers, stereo receivers and tube amplifiers.”

The AP4 passive speakers are full-sounding bookshelf speakers in a small satellite-sized package. The AP4 has excellent bass response for its size, which is obvious when it's used either as stereo speakers or satellite surrounds. AP4 sounds great sitting on stands, bookshelves and tabletops.

“We designed the AP4 to share a similar voicing and tuning with our active speakers so you’re assured a matched system no matter which speakers or our wireless products you add to your system.” said Brady Bargenquast, Audioengine co-founder.
