Dimension comparison
Design and build quality
Both the Bose TV Speaker and the Polk Audio Signa S2 are designed to fit seamlessly into modern living room setups without obstructing the television. The Bose unit is described as a compact soundbar that stands just over 2 inches tall, allowing for easy placement in front of a TV or wall mounting. Similarly, the Polk Audio Signa S2 is noted as a premium ultra-slim soundbar that also measures just over 2 inches in height. This low profile ensures that neither unit will block the TV's bottom edge or IR remote sensor. Both manufacturers prioritize a minimal footprint, making them suitable for smaller spaces or wall-mounted configurations where bulk is a concern.
Sound Quality and Drivers
The core audio architecture differs significantly between the two models. The Bose TV Speaker utilizes 2 angled full-range drivers intended to deliver a wide, natural sound and a more realistic spatial audio experience from a small enclosure. In contrast, the Polk Audio Signa S2 employs 5 powerful full-range drivers. This higher driver count generally allows for greater sound dispersion and volume potential. While Bose emphasizes the angling of their drivers for spatial effects, Polk focuses on the raw number of drivers to deliver rich audio. The presence of five drivers in the Polk model suggests a potentially fuller mid-range and overall soundstage compared to the two-driver configuration of the Bose unit.
Bass Performance
Bass response is a major differentiator in this comparison. The Polk Audio Signa S2 includes a wireless subwoofer in the box, which is dedicated to producing deep bass frequencies. This dedicated hardware allows the soundbar to offload low-end reproduction, resulting in richer audio for movies and music. The Bose TV Speaker features do not mention an included subwoofer, relying instead on the full-range drivers within the main bar. While Bose aims for natural sound, the lack of a dedicated subwoofer typically limits low-frequency extension compared to a system with a separate bass unit. For users prioritizing cinematic impact or music with heavy bass, the Polk system holds a distinct hardware advantage.
Connectivity Options
Both soundbars offer a standard suite of connectivity options suitable for most TV setups. The Bose TV Speaker supports HDMI, Optical in, and AUX in, allowing users to connect up to 3 devices. It also features Bluetooth for wireless streaming. The Polk Audio Signa S2 similarly offers HDMI ARC, optical input, and AUX connections, along with built-in Bluetooth technology. A notable distinction is the Bose feature where the first powered-on device automatically connects, which may streamline switching between sources. Polk specifies HDMI ARC support, which can simplify control via the TV remote. Both units support wireless music streaming from smartphones and tablets via Bluetooth.
Setup and Ease of Use
Simplicity is a central theme for the Bose TV Speaker, which is designed with simplicity in mind. Setup involves a single connection via an included optical audio cable or a separately sold HDMI cable. The system is designed to be up and running in minutes. The Polk Audio Signa S2 also emphasizes ease of setup, allowing users to set up the sound bar in minutes using numerous connection possibilities. Both units support wall mounting or placement in front of the TV. The Bose inclusion of the optical cable in the box may offer a slight convenience advantage for users who do not already possess one, whereas Polk users may need to source their own cables depending on the package contents.
Dialogue Clarity
Enhancing speech intelligibility is a key function for both devices. The Bose TV Speaker is explicitly designed to specifically focus on clarifying and elevating vocals and pronunciation. This suggests a tuning profile that prioritizes the mid-range frequencies where human speech resides. The Polk Audio Signa S2 features Polk's exclusive VoiceAdjust technology, which maximizes audio clarity and reduces voice delays. Both systems aim to solve the common issue of quiet dialogue in modern TV mixes. While Bose markets this as a primary design goal, Polk utilizes specific technology to achieve similar results. Users who struggle to hear TV dialogue will find dedicated features on both units to address this concern.
Price and Value
When evaluating cost against features, the Polk Audio Signa S2 presents a strong value proposition. It is priced at $249.00, which is $30.00 less than the Bose TV Speaker at $279.00. Despite the lower price, the Polk unit includes a wireless subwoofer and utilizes five drivers compared to Bose's two. The Bose model commands a premium price likely due to brand positioning and its specific dialogue enhancement tuning. However, in terms of hardware included per dollar, the Polk system offers more physical components, including the subwoofer and additional drivers, for less money. This makes the Polk option more competitive for budget-conscious buyers seeking a complete home theater upgrade.
Which one should you buy?
The choice between these two soundbars depends on specific audio priorities. If deep bass and hardware value are the primary concerns, the Polk Audio Signa S2 is the superior choice due to the included wireless subwoofer and lower price. It is better suited for movie watchers and music listeners who want a fuller sound profile. However, if the primary goal is simplifying setup and maximizing dialogue clarity without extra components, the Bose TV Speaker is a viable option. Its automatic device switching and specific vocal focus cater to users who want a straightforward improvement over TV speakers without managing a separate subwoofer. Overall, the Polk offers more features for the price, while the Bose offers a streamlined, dialogue-centric experience.
