Towering Fidelity

The Monitor 70 Series II BLK is the hallmark of the Monitor Series. Combining multiple drivers with Cascade Tapered Array technology, this floorstanding speaker offers classic Polk Audio sound quality with powerful efficiency.

Dynamic Balance® Tweeter

1” (25mm) silk/polymer composite dome tweeter with neodymium magnet structure delivers realistic vocals and instrumentals.

Dynamic Balance® Drivers

Dual 6.5” composite drivers are lightweight and stiff with better damping for lower distortion, excellent midrange clarity and high efficiency bass.

Critically-Tuned Port

Flared port minimizes “chuffing” to reduce distortion for rich, natural sound and deep, full-bodied bass.

Superior Materials

Crossovers with Mylar bypass capacitors provide detailed high frequencies, while 5-way binding post connectors offer secure connections.

Solid Construction

Non-resonant, all-MDF enclosure with 0.75” thick baffles ensures cleaner, clearer, more lifelike sound quality.

Efficient Design

Small-diameter drivers deliver wide dispersion, better mid-range and detailed bass response for open, three-dimensional sound.
