Design and Build
The Ultimea U2600 system adopts a multi-component design to achieve its surround sound promise. The main soundbar itself is constructed from metal and plastic, with dimensions that suggest a low-profile design suitable for placement in front of most modern televisions. It is wall-mountable, adding to installation flexibility. The system includes four separate surround speakers—two for the front and two for the rear—which connect via wired cables to the wireless subwoofer. This design choice allows for precise placement to create the intended sound field but requires consideration for cable management. The subwoofer features a 6.5-inch driver and utilizes Ultimea’s proprietary BASSMX technology, with bass levels adjustable through the app or remote. The overall aesthetic is described as sleek and versatile, intended to fit various room styles.
Performance and Features
Audio Performance and Surround Sound
The core promise of the Ultimea U2600 is a 7.1-channel virtual surround sound experience, an upgrade from the company’s previous 5.1-channel model. The system employs eight drivers in total: three 2.25-inch full-range drivers in the main soundbar and four more of the same size across the four surround speakers, plus the 6.5-inch driver in the subwoofer. This configuration is designed to project sound from the front, sides, and rear, enhancing audio spatiality. The system offers 13 adjustable surround levels to tailor the immersion to the room’s acoustics and user preference. It’s important to note that this is a virtual surround system and is not compatible with Dolby Audio, Dolby Atmos, or DTS:X formats. For optimal performance, the manufacturer recommends setting the connected TV’s digital audio output to PCM.
Connectivity and Compatibility
The U2600 provides a versatile set of connectivity options to suit various home entertainment setups. The inclusion of an HDMI eARC port is a significant feature, as it allows for a single-cable connection to compatible modern TVs, enabling audio return channel functionality and often simplifying control via the TV remote. Additional wired connections include optical and auxiliary (AUX) inputs. For wireless streaming, Bluetooth connectivity is supported, allowing users to play audio directly from smartphones, tablets, or laptops. The system is compatible with televisions, laptops, and mobile devices. The manufacturer specifies it is best suited for TVs 60 inches and larger.
App Control and Customization
This is the defining feature of the Ultimea U2600. The Ultimea Smart App provides extensive control over the audio experience far beyond what a typical remote offers. Key software features include six pre-tuned EQ modes (Movie, Music, Voice, Sport, Game, and Night) for quick optimization based on content. For advanced users, the app offers a 10-band equalizer for manual fine-tuning. The most unique offering is the 121 preset equalizer matrices, organized into four style categories: Bass, Pop, Classical, and Rock. This allows for deep, granular sound shaping. The app also facilitates Over-the-Air (OTA) firmware updates to ensure the system receives feature and performance improvements over time. The system also includes an upgraded multifunctional remote control for traditional operation.
Setup, Support and Ownership
Setup involves connecting the main soundbar to the TV via the preferred cable (HDMI eARC is recommended), positioning the wireless subwoofer, and placing the four surround speakers. The two rear speakers connect to the subwoofer with included 20-foot cables, providing layout flexibility. User feedback suggests the physical setup is straightforward, often taking just a few minutes. The app setup involves downloading the Ultimea Home app and connecting to the soundbar for configuration and updates. The product comes with a comprehensive set of accessories, including all necessary cables (HDMI, optical, AUX), a remote control (batteries not included), and a wall-mounting kit. The manufacturer provides an extended warranty, though the specific terms and duration are not listed in the provided data. The regular OTA updates via the app are a positive sign for long-term support.
What Owners Say
Owner feedback for the Ultimea U2600 is generally positive, with a high proportion of favorable ratings. Many users highlight the ease of setup, particularly when using the HDMI eARC connection, which allows the TV remote to control the soundbar’s volume. The sound quality is frequently praised, with mentions of clear dialogue, powerful bass from the wireless subwoofer, and a significant improvement over built-in TV speakers. The value for money is a recurring theme in reviews. Some users express satisfaction with the app’s customization capabilities, allowing them to tailor the sound to their liking. Critical feedback primarily centers on the wired nature of the surround speakers, which requires cable management, and some users note that the advanced EQ settings can be tricky to dial in perfectly. A few mention that while good, the sound may not match higher-end systems with Dolby Atmos support.
