The Flagship of Bookshelf Speakers

The LSiM series loudspeaker is Polk Audio's best high-performance loudspeaker. Polk Audio designed the LSiM series loudspeakers to create a sound that virtually transports you to the scene of the recorded performance.


Dynamic Balance

Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response, & low distortion.

3-Way Driver System

The Polk Audio LSiM series bookshelf loudspeaker employs a 3-way driver system for crisp, detailed highs; natural, lifelike midrange; and accurate, dynamic midbass.

PowerPort Bass Venting

To eliminate bass-stealing turbulence at the mouth of the port, Polk Audio engineers designed the PowerPort. It's unique shape promotes "laminar" airflow even in short tube ports by mimicking the properties of longer, flared port openings. No turbulence means no wasted power, which means more efficient bass response.
