Description
You are looking at a beautiful pair of cherry wood finish Polk Audio RTi A1 HiFi Bookshelf speakers. These are in great condition and in perfect working condition order. Tested completely before listing. There are good pictures of 5 sides of each speaker. Please see the pictures for your best view of the quality and condition of these speakers. The bottoms do not have feet so there are some light scuffs on the bottom surfaces from sitting on a bookshelf. The grills have no rips or tears. These sound as good as they look. Details From soundstagehifi.com “Technically . . . . . . the RTi A1 is a magnetically shielded, dual-ported, two-way bookshelf speaker with a 1 silk/polymer-composite dome tweeter, a 5.25 polymer/mineral-composite mid/woofer, and two ports: one each on the front and rear panels. Housing all of this is one of the most impressive cabinets I’ve seen on a stand-mount offered at this price or even quite a bit north of it. To my knowledge, Polk Audio is currently the only manufacturer offering real-wood veneers (Natural Cherry or Black Oak) on a $340/pair minimonitor -- the RTi A1’s look is one of luxuriously high quality. Looking under the impressive skin of this cabinet, I discovered that it’s built using Polk’s Damped Asymmetric Hex Laminate Isolation (DAHLI) design technology, which is used throughout the entire RTi line. DAHLI -- basically, six layers of MDF separated by five layers of viscous damping material -- is said to create optimal sheer damping (OSD) to help eliminate cabinet colorations. In addition, the RTi A1’s cabinet is internally braced, and has tapered side panels to further reduce internal resonances. The front port, just below the mid/woofer, uses a technology Polk calls Acoustic Resonance Control, which takes advantage of the cabinet’s internal resonance created by the back wave of the driver. Polk matches in frequency this form of cabinet resonance with the front port’s tuning frequency. Since the port’s and the cabinet’s internal resonances are out of phase, peak resonances within the cabinet are canceled, resulting, it’s claimed, in a more natural sound with reduced midrange distortion. The rear port, behind the tweeter, uses what Polk calls their PowerPort technology. Essentially, it’s a long, flared port with a dispersing cone mounted just past its end. This reduces turbulence in the air exiting the cone, thereby diminishing port noise, or chuffing, while providing deeper, cleaner, more authoritative bass. In designing the mid/woofer and tweeter, Polk used a process called Dynamic Balancing, in which a laser is used to study the components of the speaker at a microscopic level, in order to reduce or eliminate behaviors or artifacts that color the sound. Finally, another process, Klippel Optimization, was employed to ensure that the RTi A1 offered balanced yet dynamic sound at both low and high volumes. All of these technologies came together to help this little bookshelf -- it measures only 12H x 7.38W x 11.5D -- reach as low as 60Hz, -3dB, while maintaining an efficiency rating of 89dB. Such performance somewhat belies this minimonitor’s small size and affordable price.”
