Thivan Labs Grand Open Speaker 3-Way Open Baffle

The advantage of these Open speakers is to reproduce very natural and life-like sound, close to that we often hear in reality, without exaggeration, especially in the context of an open spacious stage. This is also why we chose these Open speakers to develop our high-end product line. Following the Open 100, Grand Open appears as an even more premium choice for the most difficult listeners.

Grand Open is a synthesis and refinement of successful research results regarding technique and design perfection, which has been achieved by ThivanLabs for over 15 years in the business. Such results come not only from our research process but also a lot from our visits to audio equipment fairs, experiencing real products, and testing with specialized equipment with exact specifications.

The Grand Open uses British drivers, consisting of three drivers on each side. We continue to exploit paper drivers’ advantages for the middle and bass sections, which is an optimal solution to reproduce thick and velvety, yet authentic sound. For the Grand Open, the combination of its drivers and design were tested and refined to create a harmonious synchronization between high, mid and low sound bands in order to create rich, detailed, and rhythmic sound.

The 10-inch midrange speaker is free from any crossover components to fully convey the sound nature. The high and super high range is supported by a treble speaker with a horn throat design for best sound spreading effect. This allows the loudspeaker to express sophisticated and high-pitched sound in love songs, string instrument performance, etc. The 18-inch Bass Speaker is controlled by a 400W Class AB power amplifier that creates deep and powerful bass.

A complete set of the Grand Open high-end loudspeakers includes: a pair of Grand Open loudspeakers and a separate amplifier to control bass range. Users can adjust the bass speaker’s volume according to their interests. Therefore, choosing an amplifier to pair with these speakers for mid and high range becomes simple and easy, as long as its capacity is within 15-40W. The speakers’ sensitivity is up to 98 dB, and they thus can work with any amplifiers available on the market. The setting up is also easier as a result. When setting them up in a room, users only need to adjust the high range. Next, the bass section will be accordingly adjusted, increased or decreased to reach sound balance, which helps simplify the whole setting up process.

The Grand Open is suitable for medium and large listening rooms, from 30-60m2. They own the flexibility to perform a wide range of music genres as they can convey the depth and sweetness in love songs, the warm rich voices of vocalists, and also the majestic sounds of heavy instruments such as drums or orchestra instruments. Those elements are often found in sophisticated symphonies, heavy bass pieces, and complex parts in classical choral performances.

Was it to be set up with a tube amplifier, it will bring out more natural life-like sound which is smooth, soothing, sweet, and warm, often found in lyrical music, Bolero, orchestral, and folk music; the details and sophistication of each instrument such as guitar, piano; and majestic sound with fast and strong rhythms.
