Meet Stuart, Yvonne, Nathan, and Vaughan. But more importantly, meet the solution to your audio dilemmas.

As far as how each 'sounds', they are near identical in the fact they timbre match NEAR perfectly. Hell to me even the r200 vs l200 sound near the same with the L200 sounding a touch cleaner and sharper. More refined is best I can describe it. But not enough to make a timbre difference with mix matching in a setup. Keep in mind, these differences only popped out when I was doing very critical side by side testing and they are minor. Day to day use I have never noticed a timbre difference in my reserve and legend surround mix of speakers. All flows perfectly. But it doesn’t matter how good a cabinet looks or how carefully is designed and crafted if the hardware that renders the sound is not capable enough. And here the Reserve series makes things a whole more interesting. Although for rear speakers we had for use were a different brand, the R700s had no problem creating a 360 degree bubble that felt cohesive and complete and worked harmoniously with the rears. Sound imaging was noteworthy and all sounds had remarkable accuracy in space making them an excellent choice if you are looking for some quality speakers for your home theater. The R700 offers uncompromising sonic performance. This full throttle loudspeaker adds two 8” woofers to deliver massive impact with striking audio clarity and detail. Perfect for use as a reference stereo pair or as the cornerstone of the ultimate home cinema.These speakers are both very accurate and neutral, no listener fatigue from boosted mids and highs but no loss of detail or focus either. The bass is tightly controlled and powerful and the overall impression is that the speaker is just effortlessly cruising along totally unflustered by even a full symphony played at high volume. They are a massive improvement on my previous B&W DM603 series 2 (22 year old version). Before buying I auditioned similarly priced B&Ws and Klipsch and the Polks were clearly better especially when listening to symphonies at high volume. I recommend these highly especially if you value accurate and effortless reproduction. Reply 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 R700 surely are big speakers as we measured them 12.6 x 45 x 16.9 in (320.7 x 1143.8 x 428.3mm) including the feet while they weight a mind blowing 79.1 lbs (35.9 kg) making them the second heavier speaker from Polk Audio that we have tested (the first place still goes to the LSiM707) and far heavier than the RTiA speakers that these are supposedly replacing.

For our first test we decided to try out Battleship in 4K UHD that comes with an explosive DTS:X mix. You can say whatever you want about the film’s quality but when it comes to its technical merits I think we all agree that they are flawless. 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. and should be viewed using a good sound system. Polk Reserve R700 Floorstanding Loudspeaker Measurements & Conclusion

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 minimizing turbulence and port noise.

The Polk Reserve R700 floorstanders deliver a bold sound, performing equally well with both 2 channel stereo and home cinema surround sound setups. A one inch Pinnacle dome tweeter provides crisp highs for detail, while the 6.5 inch Polk Turbine cone delivers clarity in the all-important midrange. The turbine cone combines a foam core with moulded turbine geometry to dramatically improve stiffness and damping, without adding extra weight. The Turbine cone lets you experience a smooth and detailed midrange and bass. Reserve Series: The Polk Reserve Series offers modern styling combined with Polk's premium Pinnacle tweeter and Turbine midrange/midbass driver that deliver high-resolution detail and imaging. Plus, Polk's new X-Port and Power Port 2.0 technology help to deliver deep and effortless bass for a more immersive experience. The Polk Reserve Series consists of three floorstanding loudspeakers ( R700/ R600/ R500), two bookshelf loudspeakers ( R200/ R100), two center-channel speakers ( R400/ R300), a LCR loudspeaker ( R350), and a Dolby Atmos height speaker module ( R900) - all sold separately. Option for freedom: Expanded sweet spot allows for exceptional acoustics from anywhere in the room.Our pioneering turbine design delivers a significant increase in cone rigidity without increasing mass. This innovation means the woofer can move with increased accuracy and speed to deliver enhanced sound resolution, enabling you to experience a breathtaking level of detail in your music and movies.
