## Description

Product Description The Lsim705 fills your world with its wide, dynamic soundstage and its capability to effortlessly achieve truly staggering volume levels. The Lsim705 features the same component complement as the larger Lsim707 loudspeaker, on a slightly smaller scale. It includes a 5 1/4 inch Mid Woofer of lightweight super cell Aerated polypropylene for smooth blending with its dual 5x7 inch Cassini oval subwoofer radiators enhanced by Polk's patented power port bass Venting. Its 1 inch ring radiator tweeter, a feature usually found only in exotic speakers, reveals Pinpoint details for realistic imaging. Use the Lsim705 in mid sized rooms where you want the full on impact of the legendary Polk sound. From the Manufacturer The ultimate statement of Polk's mission, the LSiM707 is like no other loudspeaker in its price range. Experience realistic, transparent midrange reproduction, pinpoint detail and the deepest bass with the LSiM 707. Engineered into a sculpted, state-of-the-art enclosure and finished like a beautiful piece of furniture, there is simply nothing like the LSiM 707.key featuresPolk's exclusive dynamic sonic engine design optimizes the midrange driver and the ring radiator tweeter in separate interior chambers for improved transient response, superior imaging and greater horizontal off-axis response.Cassini oval subwoofer, with more surface area than round drivers, dramatically improve low-frequency response for deep, well-blended bass.Our innovative overhung voice coil design augments the excursion length for subwoofer drivers, increasing their power-handling capabilities and enhancing bass response.Extended linear motion voice coil design allows lots of movement in a limited space, eliminating impedance and extending mid- and high-frequency response.Lightweight, rigid cast aluminum baskets are designed for precision motor alignment with unobstructed linear movement and ample venting. take a look at this product technology Dynamic Sonic Engine This is a molded enclosure within the cabinet that houses the super-accurate ring radiator tweeter and the extended motion midrange driver in their own separate, tuned compartments. This aligned, optimized array contributes to wide, uniform dispersion in the critical 200Hz - 2kHz range. The dynamic sonic engine, in turn, lives in a separate, rigidly braced enclosure-within-the-enclosure. This separation and specialized tuning measurably reduces performance-robbing back wave reflections. The result is astonishing detail and realistic imaging, with improved transient response, exact timbre-matching, and greater horizontal off-axis response.Enhanced Ring Radiator Tweeter Our engineers took the ring radiator tweeter, usually seen in only the most exotic speakers, and found way to improve it. They reshaped the tweeter's bullet-shaped phase plug to eliminate horn-loading and improve dispersion. Redesigning the tweeter faceplate and the diaphragm added efficiency. Finally, they gave their new ring radiator tweeter its own tuned enclosure within the dynamic sonic engine. This enhanced ring radiator boasts higher power handling, extended dynamic range, better dispersion and extended top-end responseSuper Cell Aerated Polypropylene Cone MaterialThe perfect cone material is lightweight (for faster, more efficient action) and stiff (for less distortion-causing flex), with enough internal damping to suppress and offset any limitations of its lightweight stiffness and our super cell aerated polypropylene cone material is about as perfect as it gets. It's the ideal balance of lightweight stiffness with high damping, along with good resistance to moisture, UV and temperature extremes. Our drivers are fast, linear and nearly resonance free.Extended Linear Motion (ELM) Voice Coils Allowing lots of movement in a limited space, ELM voice coils power the LSiM midrange and mid-woofer drivers to extend their higher frequency response with much less impedance. (LSiM subwoofers use overhung coils, which allow the larger excursions and greater power handling necessary for big subwoofer performance.)The LSiM Enclosure The enclosure is an integral part of the sound design of the new LSiM Series. All LSiM cabinets are made of 1.0" MDF on the sides, 3/4" on the back and bottom, and wide radius baffles of robust 1 1/4-inch MDF. Substantial internal cabinetry, each driver with its own separate asymmetrical chamber, increases efficiency and banishes internal resonances and standing waves, for high power handling and incredible smoothness. The narrow baffle with its wide radiuses enhances the imaging for a very wide, deep and well-defined soundstage. why you should consider this productThis is the pinnacle of home audio performance. It's the place where recorded sources are accurately revealed, where their true dynamic qualities are fully experienced. It's the place where movies reach off the screen and envelope you. This is the reason we got into this business in the first place: to ignite your entertainment with realistic audio impact, lifelike details and deep bass thrills.

Review: Greatest speakers I have ever heard - Finally I got these beautiful speakers! Delivery was very fast! Only 2 days. Good job desertcart. Packaging is very good as well, good protection and easy to open. Speakers itself have a nice finish! They look awesome! As my wife said this is now the best part of our furniture :) The only minor negative think is what happened in the first day when I start listening them. The small piece with Polk Audio brand name which you see at the bottom of the front panel has fallen apart. Not enough glue probably. Should not see such things in the expensive speakers, but could happen some time. Not a big deal for me. Sound quality is excellent! I was blown away by the bass and stereo image! It's something you need to here yourself! I have another pair of Klipsh RP280 speakers, so I have compared Polk and Klipsch and this is like white and black. Polk 705 is my favorite speakers now for the stereo music and Klipsch working for the home cinema. Good job Polk Audio!
Review: Almost perfect - Clarity and imagine is probably the best I have ever heard from a pair of tower speakers. I compared these with the svs ultra towers and the choice was difficult. The ultra has a much better base response and also the Twitters seems more pronounced and overall more musical generally. However what stands out with the lsim 705 is the overall warm tone and clean stereo musical separation . It makes for a pleasant relaxing well balanced nuteral listening experience you may need a Subwoofer to supplement the sub 35htz frequency but it is well worth the extra cost. I ended up keeping both ultra and lsim 705. I got thr lsim 705 for less than 800 for the pair , the ultra full price. I give the ultra a slight edge simply because it does everything well. The polk however is a stereo master, not a party speaker. Overall for the price I paid, I give it 5 stars, if I had paid full price I would have given it 4 for weak base response.

### ⭐⭐⭐⭐ Sound Great
*by M***L on April 19, 2020*

There was some minor box damage from shipping, but I didn't notice any damage to the speakers. The speaker base/platform had loose screws on both speakers upon delivery. The LSiM 705's sound and look great. I have them paired to a Rotel 100w per channel receiver. They seem a little more power hungry than my previous Polk Audio RTA 11TL's, but they play loud and clear.
