The innovative Pinnacle Ring Radiator Tweeter expands high-frequency sound dispersion, creating an immersive cinematic audio experience no matter where you sit. The Turbine Cone Woofer enhances cone rigidity for improved speed and accuracy, delivering an unprecedented level of detail. The l800s are a lot better than the r700. but it's for reasons imo not typically said as to why one is better.. I'll try to do my best to explain. I have l800s up front and r700 side surrounds. This tweeter comes directly from Polk’s flagship Legend series, and its ring radiator design means no central dome to enter break-up modes, so here achieving lower distortion within the listening range and indeed beyond, as the Pinnacle is ‘hi-res certified’. Further relieving resonance in the floorstanders is a new internal bracing Polk calls Column Resonance Control. In the bookshelf models and the smaller floorstander of the Reserve range, Polk has applied the same principle to this torpedo-clutching new X-Port; this uses a set of closed-pipe absorbers tuned to the internal frequency of the cabinet, acting as an eigentone filter (the port itself is labelled ETF) to maintain the bass output while aiming to reduce traditional speaker distortions, clarifying the upper bass and midrange.

Reserve’s sleek cabinetry hides a world of audio innovation. Cabinets are carefully cross-braced to best eliminate unwanted interior resonances. Rounded exterior corners help disperse sound broadly around the room with minimal diffraction, creating an open sound stage. OPTIONAL HEIGHT MODULE The R200 proved truthful at both low levels and high, able to deliver a solid bass and a remarkable clarity of midrange assisted perhaps by that new X-Port, while the Pinnacle tweeter gifts an airy and open treble beyond the likely limits of perception. Option for freedom: Expanded sweet spot allows for exceptional acoustics from anywhere in the room. On top of the cone of the waveguide we build a ‘hollow pole’ with an opening that is halfway into the port, and tuning of this pipe is done to multiples of tuning of the port frequency,” says Polk. The effect is significant, notably reducing a large 14dB resonance peak occurring at 700Hz.Tl;Dr l800 has better deeper bass due to larger cabinet and 10in woofers. Soundstage is much larger and expensive and SDA effect is awesome. The acoustic instruments in the arrangement of Missy Higgins’ Nightminds became almost recessed, such was the prominence and crispness of her vocal. On Sweet Arms of a Tune it was the acoustic guitar which was thrust forward, with Higgins’ vocals almost too insistent; the R200s don’t forgive an edgy production. But when she is more truthfully captured, as on Greed For Your Love, the realism was tangible. Should you need to hide the drivers, for aesthetics or protection, the magnetic grilles are described as anti-diffraction and acoustically-inert, but for our ears they audibly tempered that open treble; we left them off, preferring the aesthetic and the response.

Unrivaled Sonic Performance: Striking audio clarity and authentic sound reproduction with two 8" woofers. But the L800has the obvious benefit of a roided out structure (r700 internals are very good though cabinet wise as well) and the imaging/soundstage on the L800 has no contest. It blows the imaging of any speaker I heard out of the water. It, when set up properly (which isn't hard. I don't even have any treatment and still worked ok. I can't wait for the day I can treat the room and see how much better the SDA effect is) can surround you and make it seem like your side surrounds are active when they really aren't and it can somehow project a 3 dimensional soundstage where, depending on the recording, can separate the instruments in a field to where you can tell ok, this violin is here and a snare drum here. You won't get this on all sources though, especially if the recording wasn't done well. Very hit or miss if a song will have a wow factor or sound 'normal' like on your old speakers. Songs with good stereo separation or binaural recordings shine on em. Moving in stereo by cars, surprisingly shoulder lean by young dro (he has random voices in entire song in random locations. Sometimes to side, front left, right etc. Wasnt expecting such good mixing on that rap song lol) While their response remained uniform across a wide sweet spot, their considerable imaging abilities were clearly best enjoyed sitting dead centre to within a few centimetres, to perfectly equalise the treble from those ring radiators.

Polk’s new Power Port 2.0 is the latest version of our successful Power Port technology. In addition to Power Port’s carefully engineered port design that smooths the flow of air as it exits the cabinet through the port, X-Port adds a set of closed-pipe absorbers that are specifically tuned to unwanted cabinet and port resonances. Together, these two technologies combine to function as Power Port 2.0 to deliver smooth, detailed audio. Combined with dual 8” woofers, you’ll get louder, cleaner bass while minimising turbulence and port noise. EXCEPTIONAL CABINETRY The Polk Audio - Reserve R700 - Flagship Floorstanding Speakers are the pinnacle of home audio, offering unrivaled sonic performance that will change how you perceive sound. With two immense 8" woofers, these speakers provide striking audio clarity and detail, breathing life into your music and movies. Personal Touch: Our commitment is to craft an audio experience tailored to you. Forget one-size-fits-all. The original PowerPort was all about bass performance and to avoid port noise,” Polk personnel apprised us at a special presentation to EISA editors. “The port on a loudspeaker helps to get more lower frequencies and to increase sensitivity of the speaker – but maybe nobody told you that this comes at a price.” The Polk Audio R700 is a beefy, three-way tower speaker sporting a one-inch Pinnacle Ring Radiator tweeter, a six and a half inch Turbine Cone midrange and two, yes TWO, eight-inch bass drivers –much of which is carried over from Polk’s costlier Legend Series. The speaker’s four drivers and bottom-facing port combine for a reported frequency response of 38Hz to 38kHz, with a sensitivity of 88dB and a minimum impedance of 3.6 Ohms, meaning this large tower isn’t necessarily impossible to drive, though a competent amplifier will give you the best results.

The Polk Reserve cabinets use precisely engineered braces and internal enclosures to minimise standing waves and eliminate unwanted resonances that may colour the sound of your music. Laser Doppler Vibrometer designed point to point bracing, combined with new Cabinet Resonance Control, eliminates any unwanted panel resonance within the cabinet. Magnet, acoustically transparent grilles are provided for a clean and attractive aesthetic to these speakers. Polk Reserve R700 Floorstanding Speakers features We kept them on light duties for a week to warm them through while deciding on positioning, settling on solid stands toed in slightly to keep their pointy tweeters at ear height and directly at our ears.Meet Stuart, Yvonne, Nathan, and Vaughan. But more importantly, meet the solution to your audio dilemmas. While in the larger Reserve models this driver is used for the midrange alone, its bass performance is, as we’ll see, still suitable for unsupported use in a standmount design, maintaining output fully down to 150Hz then declining relatively slowly to be 6dB down around 70Hz. The biggest and most annoying resonance of a floorstander is between the foot and the top plate,” Polk tells us. “Depending on the height of the cabinet this is usually between 150 and 200Hz. Our CRC construction clearly eliminates the resonance peak of the cabinet – the result is uncoloured bass and midrange.”
