Polk Audio MM691
$240.00
Released July, 2008
The Pros:Installation is quick and straight forward, no special considerations. Sound is full and resonant. Lows are detailed and clear, no boom or distortion.
The Cons:Some harshness in the highs. Need to mount the crossover for the tweeter and woofer separately. Speaker wire on the cross over is short, makes tucking everything away difficult.
The Polk Audio MM691 is a high performance 3-way 6" x 9" speaker that is designed for sport vehicles such as Jeeps and boats. These speakers are based on the flagship SR Series but maintain a competitive price.
