TRIANGLE BOREA BR05 2-Way Bookshelf Speakers (Pair)

Experience the perfect blend of vintage-inspired design and modern Hi-Fi performance with the TRIANGLE BOREA BR05 Bookshelf Speakers. Designed for music enthusiasts seeking powerful, room-filling sound without traditional floorstanding speakers, the BR05 combines an oversized 21 cm (8.3-inch) midwoofer with TRIANGLE's signature 25 mm EFS silk dome tweeter. The result is a dynamic, engaging listening experience with deep, controlled bass, natural vocals, and detailed high frequencies. Ideal for rooms ranging from 15 to 45 m², the BR05 brings impressive scale and musicality to any stereo system.

At the heart of the BR05 is a custom-designed midwoofer featuring a cone made from 100% natural cellulose pulp. Carefully engineered to balance powerful low-frequency performance with accurate midrange reproduction, this driver delivers rich instrument textures, expressive vocals, and a natural tonal character. TRIANGLE's Efficient Flow System (EFS) tweeter features a 25 mm silk dome and phase plug to promote smooth high-frequency dispersion, precise imaging, and an expansive soundstage. Together, these drivers provide a balanced frequency response of 42 Hz to 22 kHz, preserving the detail and energy of your favorite recordings.

Engineered for exceptional acoustic control, the BR05 features a reinforced high-density MDF cabinet with panels measuring up to 21 mm thick. TRIANGLE's exclusive Driver Vibration Absorption System (DVAS) uses a high-density EVA foam gasket to connect the driver's motor to an internal brace, helping absorb mechanical vibrations and reduce unwanted cabinet resonances. Two additional internal braces further improve rigidity, allowing the speaker to deliver cleaner bass, improved clarity, and more faithful sound reproduction. A carefully designed passive crossover featuring selected components maintains accurate signal distribution between the drivers.

The BR05 incorporates dual front-firing bass-reflex ports that distribute airflow more efficiently, minimizing turbulence and improving low-frequency control at higher listening levels. Their front-facing placement also provides greater flexibility when positioning the speakers near walls. Dual binding posts support bi-wiring and bi-amplification, allowing additional customization of your Hi-Fi system. Each speaker includes a specially designed base that tilts the cabinet upward by 10° for optimized sound projection and listening alignment. For more traditional placement, the BR05 is also compatible with optional TRIANGLE S03 speaker stands.

Combining retro-inspired styling with contemporary acoustic engineering, the BOREA BR05 features an elegant two-tone cabinet design that complements a wide range of interiors. Available in Black Ash, Light Oak, Chestnut, Green, and Frosted White, these bookshelf speakers bring a distinctive visual presence to any listening space. Whether you're building your first dedicated stereo system or upgrading an existing Hi-Fi setup, the TRIANGLE BOREA BR05 delivers powerful bass, refined detail, and timeless style in a versatile standmount design.
