Polk Audio® 6.5" Bookshelf Speaker-Midnight Mahogany-LSiM703-MIDNIGHT MAHOGANY

Polk Audio® 6.5" Bookshelf Speaker-Midnight Mahogany with 1" dynamic balance tweeter and orth crossover design


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.
