Designed For Immersive Home Theatre
The PLATINUM LCRS v.4 is designed for home theatre systems that demand convincing dialogue, detailed effects and dynamic musical reproduction without requiring conventional floorstanding speakers in every position.
Its three-way architecture assigns high-frequency, midrange and bass reproduction to dedicated drivers. This design supports clear dialogue and vocal detail alongside the scale and impact required for cinematic soundtracks. The model’s LCRS configuration also offers flexibility for system designers planning front-channel or surround-channel installations.
With support for horizontal and vertical mounting, the speaker can be positioned to suit the room layout, screen placement and listening area. Correct placement and calibration remain important for achieving balanced coverage and seamless integration with the other speakers in the system.
Detailed Highs, Natural Midrange And Controlled Bass
At the top end, the 25 mm TPTTD-I titanium dome tweeter works with TAGA Harmony’s TWG-I waveguide to support detailed high-frequency reproduction and broad sound dispersion.
The 133 mm TPACD-II aluminium-cone midrange driver is designed to provide smooth, articulate reproduction of dialogue, vocals and instruments. Two 165 mm TPACD-II aluminium-cone bass drivers extend the system’s output into the lower frequencies, helping deliver weight and impact for action sequences and music.
TAGA Harmony specifies a frequency response of 38 Hz–40 kHz and sensitivity of 90 dB. With a recommended amplifier power range of 20–220 W and a published power-handling rating of 150 W RMS, the speaker is intended for use with a suitably matched amplifier or AV receiver.
Engineered Enclosure And Precision Crossovers
The PLATINUM LCRS v.4 uses TAGA Harmony’s third-generation TLIE-II enclosure design. The manufacturer specifies an 18 mm front baffle and 15 mm cabinet walls, together with internal damping material intended to reduce standing waves and unwanted resonances.
Its Ogrodnik crossover sections are designed by Polish loudspeaker designer Arek Ogrodnik. Carefully selected components are used to support driver integration, tonal neutrality and precise reproduction.
The internal wiring uses multi-stranded oxygen-free copper, while gold-plated speaker terminals accept bare speaker cable up to 10 AWG and commonly used connector types. These construction details complement the speaker’s driver and enclosure design.
Flexible Installation And Refined Design
The PLATINUM LCRS v.4 is intended for installations where high-performance sound must work with the room’s interior design. Its wall-mounting arrangement supports horizontal or vertical positioning, and the magnetically mounted grille helps maintain a clean appearance.
The enclosure measures 70 × 30.5 × 15 cm with the grille fitted in the specified vertical orientation and weighs approximately 12 kg per speaker. Before installation, confirm wall strength, mounting clearances, cable routing, speaker orientation and the intended listening position.
For the best results, professional system planning is recommended to ensure suitable amplifier matching, consistent placement and effective integration with the other channels in the home theatre.
