Polk Reserve R350C Slim White (piece)
The Polk Reserve R350 is a passive two-way centre speaker designed for home cinemas, with an emphasis on maximum dialogue clarity and precise mid-range sound reproduction. Its low-profile design and sealed cabinet allow for flexible placement without negatively affecting the acoustics. The speaker uses advanced technology from the Reserve series, including a Pinnacle Ring Radiator tweeter and four Turbine Cone mid-bass drivers, which ensure a detailed and dynamic sound performance with wider room coverage. Thanks to its Hi-Res Audio certification, the speaker supports the reproduction of modern lossless formats and offers a high level of detail. The design allows it to be used not only as a centre channel but also as a left or right speaker (L/C/R) within a home cinema setup.

Construction and Drivers
The Polk Reserve R350 speaker uses a two-way design with one 1” Pinnacle Ring Radiator tweeter and four 4” Turbine Cone mid-bass drivers. The tweeter is designed for wider dispersion of high frequencies and better coverage of the listening area. The Turbine Cone mid-bass drivers provide high diaphragm rigidity while maintaining low weight, which allows for more accurate reproduction of mids and bass. The crossover frequency is set at 2,700Hz.
Sound and Technology
The speaker is Hi-Res Audio certified and allows for the reproduction of frequencies up to 35kHz (-3dB). The sealed construction eliminates unwanted air turbulence and ensures accurate dialogue reproduction without distracting artefacts. The sound performance is optimised for home cinema, with an emphasis on voice clarity. The speaker is compatible with Dolby Atmos and IMAX Enhanced setups, allowing it to be integrated into modern multi-channel home cinema systems.
Connectivity and Compatibility
The Polk Reserve R350 speaker is equipped with a single pair of nickel-plated 5-way binding posts for connection to an amplifier or AV receiver. The minimum impedance of 3.9 Ohms requires a compatible amplifier, and the device supports amplifiers with 4, 6, and 8 Ohm outputs. The recommended amplifier power per channel is in the range of 25 to 200W. The speaker is supplied as a single unit and can be used as a centre, left, or right channel within a home cinema.
System Type
An active speaker is one that has a built-in amplifier, so all you need to do is connect it to a sound source, either wired or wirelessly, to listen.Passive speakers are more often referred to as speaker systems. They are intended for high-quality, loud, and dynamic listening in the comfort of your home and are not suitable for frequent transport. The main advantage of passive speakers is the ability to connect a variety of sources via a separate amplifier.
Number of Channels
The number of channels in speaker systems and home cinemas indicates the number of independent audio signals (speakers) and subwoofers, most often in X.Y format (e.g., 2.0, 5.1). It indicates how many audio tracks are reproduced simultaneously, which determines the spatial experience and bass depth of the system, from basic stereo sound (2.0) to surround sound (5.1 and higher).Specifications
