Dynamic Bass EQ:
As the human ear perceives frequencies differently with variations in output, Klipsch R51PM Bookshelf Speakers will dynamically match the ear’s ability to hear lower frequencies. Typically, only available with audio/video receivers, dynamic volume is a first for Klipsch-powered monitors. What you get is powerful bass whether the listening volume is low, cranked up or somewhere in between.
 
Custom-tuned Amplification:
Klipsch R51PM Bookshelf Speakers leverage independent, ultra-low noise amplifiers that are custom designed to maximize system performance and eliminate the need for external amplification. That means that world-class Klipsch engineers have full control of the signal path. We've tuned the components to be a perfect match, making the system sound incredibly immersive and filling your room with incredible acoustics.
 
TRACTRIX® Horn Technology:
Klipsch's exclusive 90x90º Tractrix® horn technology ensures that the speaker's high-frequency energy is aimed at the listener and reduces artificial reverb or filtering caused by indirect sound bouncing off of walls. Using this proprietary focused technology gives you the best clarity, dynamics, and detail from your movies and music.
