## Description

Polk Reserve R400 Powerful Center Channel Speaker for Immersive Audio Performance. Polk's Reserve R400 Center-Channel Speaker is a high-performance loudspeaker that delivers ultra-clear and crisp highs, smooth and detailed midrange, and effortless bass. It features a 1" Pinnacle Ring Radiator Tweeter and dual 6.5" Turbine Cone Woofers with Hi-Res Audio Certification, Dolby Atmos, and IMAX Enhanced support to produce high-quality sound with pure detail. Whether you're listening to music, watching movies, or playing video games, the R400's bass reflex cabinet with a rear-firing port and Polk's Patented X-Port Technology with Eigentone Filter (ETF) ensures tight, distortion-free bass for an immersive audio experience. The premium, large 5-way binding posts ensure an easy, efficient setup with a lossless connection. Place this powerful center speaker on a stand, shelf, tabletop, or any flat surface, or mount it on the wall using integrated rubber feet. Pair with two R200 bookshelf speakers, and two R700 tower speakers or with two R350s as L/R surrounds, and add an R900 height module for depth (all sold separately) to create a multichannel surround sound system. The R400 is compatible with the latest file formats like DSD, FLAC, WAV, ALAC, and MQA, so you can experience superior audio performance at home.

Review: I have tried several different studio monitor setups (with and without subwoofers) and several other prosumer FrankenPatches (including floor standing speakers with subwoofer in the space you see here) for my bass guitar practice. None was able to reproduce a non-clipping, saturated, moderate level bass guitar signal without buzzing or otherwise clipping at the drivers. What you see here substitutes for a $10k+ mid-field 3-way monitor/subwoofer setup at one-tenth the price, brilliantly. When I finally went off the deep-end and mounted these two (on-sale!) Polk R400s on Pyle stands, as you see, everything changed. My basses have never sounded better reproduced, at any price. Now I'm set with a DBX Venue 360 handling low-latency room EQ and crossover, with the low-end out to a Zu Undertone in the corner and stereo to two Schiitt Vidar monoblocks powering the Polks. Thick, chewy, loud bass shakes the house! The Polks breath bass like its just air.
Review: The product is just beautiful to look at.
