IntroductionPolk Audio is a company that has been around for a long time. In the 80s, I used to look at Polk speakers with a sense of awe, as many of them were large units with multiple drivers making them look quite complex. Over the years, Polk went quite a bit down-market, and established relationships with several mass market chain retailers. The volume of speakers sold increased, but Polk no longer appealed as much to the more discriminating buyer. Polk is now trying to go a bit up-market again with the introduction of the LSi series. The LSi9 is one of the “bookshelf” models in this lineup (second up in the series), and its quite the unique loudspeaker. The DesignThe LSi9 is deeper than the average bookshelf speaker, and has a rear port with a baffle that diverts the air to the sides. This baffle, called the Power Port, is designed to allow the speaker to be placed close to a wall.The speaker is a 2 ½ way design, as the bottom woofer works up to 200 Hz, the top woofer to 2.4 kHz, and from there on the center mounted tweeter takes over.The speaker is constructed of ¾ inch MDF sides, and has a layer of either ebony or cherry veneer over it.Rapping on the speakers shows that they are fairly well built and inert. The tops and bottom have a shiny black polished surface, and the front grille is black.On the front are two small ports that are termed Acoustic Resonance Control Ports, and are supposedly designed to help midrange performance by increasing vocal clarity, image stability, and image depth.The gold-plated binding posts on the rear are set up to allow bi-wiring, but the posts were too thick for my spade terminated speaker wires, so I would recommend banana plugs.Polk states that the sensitivity of the LSi9 is 88 dB, and impedance is 4 Ohms.This would indicate that an amplifier should be carefully chosen for this speaker, preferably one that pushes quite a bit of current.Because of the large size and heavy weight (33 pounds) of the LSi9, it was a bit difficult to place on the speaker stands I had on hand, so I would recommend that stands also be chosen carefully for this speaker.The LSi9 was tested on two separate systems. The first, my friends, consisted of a Plinius integrated amp and preamp hooked up to a Theta Miles CD player, with Joseph Audio RSi25 speakers.The second, mine, had the front B&W Nautilus 804 front speakers replaced by the Polk LSi9s, and was hooked up to a Classe CAV-150 amp, a Sunfire Theater Grand II processor, and a Marantz DV-8300 player as the source. • Drivers: One 1 Ring Tweeter, Two, 5 1/4 Mid/Woofers; Ported Enclosure• MFR: 38 Hz - 27 kHz• Nominal Impedance: 4 Ohms• Sensitivity: 88 dB/W/M• Size: 15 1/2 H x 8 5/8 W x 15 1/4 D• Weight: 33 Pounds Each Jolida JD-1701 u0026 JD100 Stereo Tube Amplifier u0026 CD , Polk Audio LSI-9 Speakers Combination Video will open in a new window Using the eBay App?

Product DescriptionThe Polk Audio LSi9 bookshelf speaker is a bookshelf speaker that delivers superior linearity, definition and imaging, as well as bass response thats rich, deep and satisfying. Its superior musical accuracy equals serious theatrical impact. Like the whole LSi Series, it is highly accurate and intensely musical. Its dual driver and Ring Radiator Tweeter (rare in a speaker of this price) present a large soundstage without sacrificing pinpoint localization. The Mylar bypass capacitor in the high pass crossover extends and flattens high frequency response. Hear musical details youve never heard before. Listen to the LSi Loudspeakers with SACD and DVD Audio sources to reveal higher accuracy and resolution, with more dynamic response and superb focus; true three dimensional imaging and remarkable reproduction of even the finest details. Items are lightly used as they were my Grandfathers. Let me know if you have any questions on this listing.

The Polk Audio LSI9 Audiophile Speaker is a wired front left speaker with a weight of 34 pounds. It is designed for high-quality audio performance and is part of the LSI9 model series. This particular listing is for the left speaker only. Works great even as a single speaker mono..

The Polk LSi9 speakers are a marvel of audio engineering, designed to deliver a captivating auditory experience. At their heart, they feature a dynamic duo of a 5.25 mid-woofer and a 1 ring radiator tweeter. This combination is meticulously crafted to produce a harmonious blend of sound that is both warm and clear, capable of capturing the subtlest nuances in your favorite music or movie soundtracks. The design of the LSi9s is not just about aesthetics, but also about optimizing the sound projection. The vertical presentation of these speakers is specifically engineered for a listening height where your ears align with or slightly above the tweeters axis. This alignment, which is approximately 11 from the base of the speaker, enhances the speakers imaging capabilities, both vertically and horizontally, creating a more immersive and realistic soundstage. At lower volumes, the LSi9s operate within their sensitivity rating of 88dB. This ensures that the sound they deliver is pleasing yet not overpowering, perfect for those quiet nights when you just want to relax with some soft music. However, when you feel the need to crank up the volume, these speakers are more than ready. Their power handling of up to 200 watts comes into play, transforming their sound into something more resolute and warm, filling your room with rich, robust sound. The LSi9s frequency response of 38Hz-27kHz is another testament to their superior design and engineering. This wide frequency range enables them to move large amounts of air with no noticeable compression, revealing subtle differences in soundtracks with a high level of resolution. The crossover frequency of 2.4kHz ensures a seamless blend of high and low frequencies, creating a balanced and coherent sound. When used in a quintet for a surround sound setup, the LSi9s create an immersive environment that transports you right into the heart of the action. The speakers nominal impedance of 4 ohms and recommended amplification of 20-200 watts per channel ensure that they maintain their unique sonic personalities as sounds travel from speaker to speaker, creating a cohesive and enveloping soundscape. In the competitive landscape of in 2003 dollars $2000 ($3200 in 2024 dollars) a pair category, the Polk LSi9 speakers stand tall. Their combination of superior design, wide frequency response, and powerful performance make them a standout choice for any audiophile. Their exquisite sound reproduction and immersive capabilities make them not just a purchase, but an investment in a rich and rewarding auditory experience. The extraordinary value is there for you to enjoy. Don’t miss out there won’t be many cleaner pairs available. Per eBay rules the following terms are agreed to by both parties. We agree these are vintage speakers and while they do perform as intended, no promises or warranties are made or offered. Returns will require a picture of the damaged shipping box, a picture of the damaged speakers that is not in the pictures, and a list of lost functionalities. Thank you and good luck!!!!
