Incredible Sound. Affordable Price.

This high efficiency, multiple-driver design allows the Monitor 70II floorstanding loudspeaker to better reveal the classic Polk sound (open, spacious and clear), even when driven by modestly-powered amplifiers and receivers. This is a hallmark of the classic Monitor Series speakers. Cascade Tapered Array technology delivers big bang for the buck, with maximum bass, detailed imaging and clear midrange.

Monitor70II Features:

1-inch (25mm) fabric/polymer composite Dynamic Balance® dome tweeter with powerful Neodymium magnet structure delivers clear and detailed high frequency response for realistic reproduction of vocals and instruments.

6 1/2-inch bi-laminate composite Dynamic Balance drivers are lightweight and stiff with good damping for high efficiency, excellent bass and lower distortion.

Multiple small-diameter driver design delivers wide dispersion, better mid-range, and more detailed bass response for an open, "box-less" three-dimensional sound.

Cascade Tapered Array (2-1/2-way) design. Both drivers play bass frequencies but only one driver (the upper one) plays upper-midrange frequencies. This method provides maximum bass output along with precise imaging and detailed midrange response.

Non-resonant all-MDF enclosure construction with 3/4-inch thick baffles and front to-back and side-to-side internal bracing ensures cleaner, clearer, more lifelike sound quality.

Crossovers use Mylar bypass capacitors for more detailed high frequencies.

Dual 5-way binding post connectors, allowing for more secure hook-up options, as well as bi-wiring and bi-amping flexibility.

Monitor Series speakers are "modern living accessories" that make a stylish statement in either black or cherry wood grain finish, with titanium faces.

Bold, fat stabilizer feet that ensure stability on carpet or hard floors for more precise bass response and superior imaging.

Slim tower design has a footprint of less than one square foot.

Critically tuned flared port minimizes port noise ("chuffing") for good low frequency extension with low distortion, resulting in natural, full-bodied sound with rich bass.

All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.
