Polk Audio MM651
$200.00
Released June, 2008
The Pros:Sound outputting is clear and warm - mid and high ranges are reproduced without harshness/distortion. Functions well as a rear speaker in conjunction with a front component unit - versatile frequency handling is complimentary to multi-speaker configurations. High signal-to-noise ratio provides sensitive, powerful volume - most users will not require the speakers to go beyond the 85% level.
The Cons:Coaxial layout may not respond well to outboard equalization - may cause frustration amongst sound experts and audiophiles. Not compatible with shallower doors, despite what is listed on Amazon and official website - sporty, streamlined vehicles are likely to encounter door panel issues.
