We wanted to dramatically improve imaging and mid-bass performance, so they redesigned the midbass driver used in the LSiM series, Gannon explained: This is the third generation of this cone.COVID-19 notwithstanding, summerwarmth, flowers, leaves on treeshas descended on Greenwich Village, my New York City home for the past 30 years.
For Polk Audio Computer Speakers Driver Used InWhat hasnt descended are tourists, belching motorcycles, behemoth sports cars, beer drinkers, and the usual summer hell-raisers, the sort that wouldve sent legendary Village bohemians Kerouac, Ginsberg, and Burroughs running back to their cold-water flats. With these absences comes something unique to my downtown experience: peace and quiet. As I write this, in early June, the streets are mostly empty, birdsong seems pleasantly amplified, and my neighbors seem more relaxed and convivial. The famous 93-year-old Caffe Reggio, whose customers have been moved out to the street in obeyance of the citys Phase 3 reopening rules, can breathe. This diminution of noise and increase in quiet makes high-fidelity listening a more relaxed indulgence. I can immerse myself in listening, for work and pleasure, to a degree that seemed impossible here a few months ago. Into this solace and sanctuary comes the Polk Audio Legend L100 bookshelf speaker (1199pair). When Polk Audio was founded, in Baltimore, Maryland, in 1972, I was barely a teenager, but I already considered myself an audiophile. My audio buddies lusted after (and occasionally possessed) brands such as NAD, KEF, Phase Linear, Bang Olufsen, and JBL, including its famous L-100 studio monitor. In those days, Polk Audios hyphenless L100 loudspeaker was still decades in the future, but company founders Matthew Polk, George Klopfer, and Sandy Gross (who later founded Definitive Technology and GoldenEar Technology) began their company by designing a PA system for a bluegrass concert. The first Polk Audio loudspeaker, the Model 9, arrived in 1973, followed soon after by the two-way Monitor 7 and Monitor 10. For Polk Audio Computer Speakers Drivers With RubberBoth of those featured 6.5 midbass drivers with rubber surrounds and passive radiators. Many followed. Polks design patents piled up, including the one for SDA (Stereo Dimensional Array), which fed a modified version of the left-channel audio to the right channel and vice versa and was important in later models. At one point, Polk almost bought the holding company that owned KEF. ![]() In 1999, they went private again and in 2007 were bought by Sound United, which also owns Denon, Marantz, Class, and several other brands, including one of Sandy Grosss other former companies, Definitive Technology. The L100 and its larger sibling, the L200 (1799pair), are part of Polks highest-priced Legend series, which the company describes as the Best Speakers Polk Has Ever Made. Its driver complement is a 1 Pinnacle Ring Radiator tweeter and a 5.25 Turbine polypropylene-cone midbass unit, crossing over at 2.9kHz via an Orth crossover, named for Polk Audios Scott Orth, an engineer who has been with the company since 2000. All Polk loudspeakers and drivers are designed and specd by Polk engineering, including entry-level products, in Baltimore, Maryland, and Vista, California, Bronson Gannon, Polks global marketing manager, told me in an email. A team of about 40 engineers also do all the companys mechanical and acoustic research, including crossover development, transducer design, development, and testing. The L100s Pinnacle ring-radiator tweeter is constructed of a proprietary material from Kurt Mueller in Germany based on an open polyester weave with special coatings and treatments; the tweeter has a center waveguidephase plug that resembles a small Hersheys Kiss, which is claimed to improve the tweeters dispersion for a bigger sweet spot. The tweeter is sealed in its own chamber, which is filled with damping material, suppressing a resonance at 2.5kHz, just below the crossover frequency. The L100s 5.25 midbass drivers foam-core polymer injection cone, which is imprinted with seven evenly spaced ridges, is described in a Polk white paper as having a chewy center and a crunchy outside.
