INTRODUCTION & FEATURE
OVERVIEW
Open Baffle speaker is one of ThivanLabs’ loudspeaker designs that have been very early researched and developed because of the rare natural sound and a capacity of unlimitedly extending the soundstage. Not many other speaker designs can reproduce the sound with these outstanding typical characteristics. The strength of the open baffle design is non resonant sound that often occurs with the vent box speaker enclosure. Because of the open structure of the speaker cabinet or it can be understood to be no speaker enclosure, the buzzing sound, especially in the low frequency, is completely reduced. In a vent box speaker enclosure design, if the resonance is not optimally solved, the low frequency often is influenced first. There are two negative results that are often seen in the designs of the vent box speaker enclosure such as the bass is compressed to control the bass better but this makes the sound lose its naturalness. The other situation is a badly controlled and noisy bass. In the new generation of ThivanLabs open baffle speaker, thanks to an innovation of crossover and speaker cabinet structure solution, ThivanLabs’ designers utilizes the strengths of this design to completely improve all negative resonance and naturally reproduces the sound while all ranges are extremely excellent controlled.
The new generation ThivanLabs open baffle speakers have a very well controlled, very deep, full and clear bass with a wonderful extension that makes the stage of the sound extremely open and airy. The beautiful bass is the new generation Grand Open’s outstanding achievement. The bass is truly real, not exaggerated. Fast bass will be reproduced fast, slow bass will be reproduced slow. How the music is, the speakers will exactly reproduce the same. Therefore, the overall sound of the ThivanLabs Open Baffle speaker is very natural, relaxing and comfortable to listen to for a long time.
It is not simple and easy to succeed with the open baffle speaker design as well as get the best design to exploit the naturalness of the sound. GRAND OPEN X-Series is the version marking the next success of the ThivanLabs R&D team after many Open Baffle Speaker designs have been researched and tested by ThivanLabs since 2012 until now.
