Design and Build
The ZVOX SB500 distinguishes itself with a premium, low-resonance cabinet crafted from anodized aluminum, not plastic. This choice of material contributes to cleaner sound reproduction by minimizing unwanted vibrations. Its slim profile, at just 3.3 inches deep and 5.7 inches high, allows it to fit gracefully under most wall-mounted or furniture-placed televisions. The 43.9-inch width makes it ideally suited for larger TVs, from 50 to 90 inches. The design emphasizes versatility, supporting wall mounting, upright placement, or a flat position on furniture to complement any room layout.
A notable design feature is the disappearing four-digit display. It shows settings like volume, bass, treble, and PhaseCue level when active, then vanishes after a few seconds of inactivity to maintain a sleek, modern look. This attention to aesthetic detail ensures the soundbar enhances your entertainment setup without visual clutter, aligning with its goal of a powerful yet clean audio solution.
Performance and Features
Audio Performance and Core Technologies
The heart of the SB500’s performance is its 140-watt Class D digital amplifier, driving three high-performance speakers and two built-in, powered 4-inch MegaBass subwoofers. This configuration is designed to produce warm, natural sound with surprisingly powerful bass, reportedly down to 42Hz, all without the need for a separate external subwoofer. The PhaseCue virtual surround system aims to create a theater-style three-dimensional soundstage from the single cabinet, simulating an immersive experience without rear speakers.
The standout feature is the AccuVoice dialogue enhancement technology, derived from hearing aid research. It offers six levels of voice boost to make vocals crystal clear, a function activated by a dedicated button on the remote. This is particularly beneficial for viewers who struggle with muffled dialogue in movies and TV shows. Complementing this is the Output Leveling (OL) feature, which automatically tames sudden volume spikes from loud commercials, providing a smoother, more consistent listening experience.
Connectivity and Control
The SB500 offers multiple wired inputs for connectivity, including optical digital, RCA, and a 3.5mm auxiliary input. This array of inputs facilitates easy integration with televisions and other audio sources, and supports adding a multi-zone streaming audio receiver. The manufacturer states it works with Wi-Fi for connectivity protocol, though specific streaming apps or Bluetooth functionality are not listed as built-in features. Control is managed via the included multifunction remote. A key setup step involves programming the soundbar to work with your existing TV or cable/satellite remote, enabling seamless operation without needing multiple controllers.
Setup, Support and Ownership
Setup is designed to be straightforward, with a simple one-wire connection to the TV being a highlighted benefit. The package includes an optical digital cable, RCA cable, RCA to 3.5mm cable, power cord, remote, and programming guides. The requirement to program the unit to work with existing remotes is noted as a step for full integration. The soundbar comes with a limited warranty, though the specific duration and terms are not detailed in the provided data. There is no mention of firmware update processes or a dedicated support app, indicating a focus on plug-and-play functionality with physical controls.
What Owners Say
Owner feedback, reflected in the product’s rating, is generally positive. The consensus highlights the soundbar’s exceptional performance in delivering clear dialogue and powerful, room-filling bass from its compact form factor. The AccuVoice and Output Leveling features receive particular praise for their practical utility in daily viewing. The premium build quality of the anodized aluminum cabinet is also a frequently appreciated aspect. The overall sentiment supports the editor’s summary that it offers outstanding voice clarity and deep bass that rivals more complex systems.
