Benefits of Polk Audio LSiM 707 Floorstanding Speaker (Pair):

Polk's Dynamic Sonic Engine

Polk has an exclusive dynamic sonic engine design that optimizes the midrange driver and the ring radiator tweeter in two different interior chambers for an improved transient response, superior imaging and superior horizontal off-axis response. The enhanced, re-engineered ring radiator tweeters extend the top-end response for unbelievably incredible details and life-like imaging.

Newly designed Cassini oval subwoofer drivers

The brand new Cassini oval subwoofer drivers which come with more surface area than round drivers drastically improve low-frequency response for deep and well-blended bass. The overhung voice coil design is extremely innovative and it augments the excursion length for subwoofer drivers, increasing their power-handling capabilities and enhancing bass response. Also, the extended linear motion voice coil design allows for plenty of movement in a small space, removing impedance and extending mid and high-frequency response. They have lightweight, rigid, cast aluminium baskets have been designed for precision motor alignment with unhindered linear movement and lots of venting space.

Polk’s proprietary, patented Dynamic Balance® technology


Polk’s proprietary Dynamic Balance® technology allows for engineers to design out distortion-causing driver and system resonances so you can experience only clean and good audio. Klippel motor optimization uses laser measurement technology which ensures a smooth excursion path at either end of the volume spectrum for a consistent performance at both low and high volumes.

High quality, heavy duty LSiM enclosure construction


The LSiM features 1.0” MDF on both the sides 3/4" MDF for the back and bottom and 1 1/4-inch baffles, with substantial internal bracing and separate interior cabinetry for each driver which makes it heavy duty. All these incredibly robust and sturdy materials help remove cabinet resonances and standing waves for less distortion and more dynamic transparency. The LSiM is a chic piece of audio aesthetically, it has furniture-grade hardwood veneer cabinet finishes with sleep trim accents and no visible screws. Additionally, the ultra slim zero-diffraction grilles lock in place magnetically, and don’t hinder the sound that comes from the speakers.

PowerPort bass venting

The lower side of the speaker’s front baffle has a dual 6”x9” oval-shaped woofers. The oval shape helps them in producing tight low-frequency music and movie sounds while maintaining a narrow cabinet width. Moreover, each woofer comes with its own Power-Port which is a proprietary Polk design that positions specially designed “cones” at the mouth of the bass ports to direct moving air to remove turbulence that hinders the bass and to ensure ideal bass reproduction

Timbre-matched with all Polk Audio LSiM series

Speakers that are matched tonally deliver excellent surround sound and the LSiM floorstanding speakers are timbre-matched within their series, created with the same components throughout to achieve effortless speaker-to-speaker blending effects in multi-channel systems.

Advanced driver material for even more realistic sound

The super cell aerated polypropylene cone is the ideal balance of lightweight stiffness which is used for efficient action with less distortion-causing flex and superior damping properties. Computer-modelled, injection-modelled butyl rubber which is extremely durable in nature suppress unnecessary cone resonances for reliable and clean sound. The patented Orth crossovers elevate lower-order power handling and smoothen the impedance curve resulting in better high frequency response.

Gold-plated , professional-grade, 5-way binding posts

These floorstanding speakers come with dual gold-plated, professional style 5-way binding posts which allow for a secure connection. The dual binding posts ensure high-performance audio and the innovative no-tip hex-head floor spikes make speaker-levelling extremely hassle-free on any flooring.
