The triumph of Dynamic Balance

Two sets of gold plated fiveway binding posts are included, so bi-amping and bi-wiring options are available for even higher performance levels. The LS90s display an amazing combination of power, control, subtlety and agility. The LS90 can persuade you that you are hearing a live performance.

Polk Audio's LS Series represents the best of 20 years of groundbreaking research and design. Choose any LS model and enjoy the excitement that these products have generated among the critics and other LS owners. You will get the power, the accuracy and the impact of live music from loudspeakers of elegance and grace - a combination of value and performance made famous by Polk Audio.
