Indiana Line Lira 2 The Indiana Line Lira 2 is a two-way bookshelf loudspeaker that combines sonic precision with a compact footprint. As the smallest model in the Lira series, it serves as a coherent addition to the lineup. The implementation of a highly efficient 150 mm midwoofer ensures that, despite its modest dimensions, the Lira 2 surprises with the sheer scale and depth of its sound reproduction. This model redefines versatility in modern audio systems. It performs exceptionally well whether deployed as a surround loudspeaker in expansive home theater setups or as the primary monitor in compact stereo configurations. The Symbiotic Drive concept The Lira 2 merges decades of Indiana Line engineering expertise with an innovative design approach. It was developed based on the proprietary Symbiotic Drive concept, where the cabinet, drive units, and crossover network are engineered in parallel as a single, cohesive electroacoustic system. The construction uses carefully selected materials, including woven polypropylene (Curv), a custom aluminum-magnesium alloy (Al-Mg), rigid MDF boards, and natural bamboo. The minimalist aesthetic of this model is highlighted by a trim ring that elegantly conceals the woofer’s mounting screws, creating a sleek, seamless front baffle. Form in the service of sound A slight rearward tilt of the Lira 2 cabinet ensures better time alignment for the transducers, resulting in superior spatial sound projection. The asymmetrical, upward-tapering side panels lend visual lightness to the design while simultaneously mitigating the risk of internal standing waves. The enclosure of the Lira 2 is crafted from MDF and finished with multiple coats of durable, matte lacquer to protect the surface from scratches. Internal bamboo bracing, combined with a massive 21 mm front baffle, effectively reduces unwanted cabinet resonances. A loudspeaker akin to a classical instrument The loudspeaker comes with a magnetic grille covered in an acoustically transparent fabric. Once attached, the Lira 2 gains an elegant, unified appearance. The unique profile of the enclosure is accented by a sharply defined frame that highlights its distinct side lines. Visually, the product evokes the harmonious curves of the ancient lyre, successfully blending classical beauty with the latest design trends in the audio market. Advanced Al-Mg tweeter A key component developed under the holistic Symbiotic Drive philosophy is the state-of-the-art 28 mm tweeter, featuring a modern aluminum-magnesium (Al-Mg) alloy dome. It has been meticulously optimized for seamless integration with the midwoofer. The tweeter is set within a 3D-Guide waveguide equipped with an EQ-Ring phase plug, improving off-axis sound dispersion. Behind the dome lies a hybrid damping chamber that prevents resonances generated at the rear of the diaphragm. The driver’s motor assembly relies on a powerful neodymium magnet, while a copper cap in the magnetic gap protects the system from overheating and minimizes distortion. The result is crystal-clear, smooth, and spacious high frequencies, offering a level of sonic refinement that is exceptional in this price class. Natural midrange, precise bass The base for midrange and low-frequency reproduction in the Lira 2 is a 150 mm driver featuring a Curv cone, housed in a proprietary die-cast aluminum basket. This is one of the most advanced midwoofers in its class. Its motor system uses a ferrite magnet and a set of three shorting rings (two aluminum and one copper), guaranteeing absolute control over inductance. The second-generation Dual-Wave surround allows for the smooth handling of demanding transient signals and protects against distortion even at high excursion levels. This translates into a natural, highly detailed midrange alongside dynamic and tightly controlled bass. Meticulously designed crossover network The crossover network, positioned behind the loudspeaker terminals, features a highly refined topology utilizing premium air-core inductors, non-inductive resistors, and polypropylene capacitors. It incorporates specialized LC-Trap correction filters that maximize the potential of the loudspeaker’s drive units by damping their natural resonances, thereby enhancing sonic clarity. Following the Symbiotic Drive concept, the crossover ensures perfect phase synchronization across the entire system. This results in an exceptionally coherent and fluid sound signature, giving the listener the illusion of experiencing a single, flawless full-range point source. Versatility and dynamics The Indiana Line Lira 2 features a carefully tuned bass-reflex system with a rear-firing port. This allows for optimal low-frequency extension by leveraging room acoustics and wall reflections, guaranteeing a solid bass foundation. These engineering solutions ensure that Lira 2 will meet the expectations of even the most demanding audiophiles. The loudspeaker impresses with its transparency, mature presentation, and incredibly dynamic, well-defined bass. Its high sensitivity and versatile nature guarantee seamless pairing with amplifiers from a wide array of brands, making this loudspeaker an excellent choice for diverse audio systems.
