The AsciLab C6B are passive bookshelf speakers offering precise, powerful sound reproduction in a compact format. These 2-way speakers feature a 1“ alumina-ceramic dome tweeter with custom waveguide and phase tapping, combined with a 6” woofer with alumina-ceramic cone, all housed in an enclosure with passive radiator. The 5x8" passive radiator provides a considerable boost at low frequencies. Their design allows for lower crossover points and reduced distortion, for an extremely clear sound reproduction. The C6Bs feature a fourth-order crossover at 1.1kHz, optimized via Klippel NFS, and support up to 250W of amplification. They are ideal for demanding audiophile or professional studio use.

AsciLab C6B tweeters feature a waveguide and internal phase plug designed to precisely manage sound dispersion. These elements avoid phase interference, reduce internal resonance and improve off-axis dispersion. The advantages of this type of configuration translate into a more linear frequency response, reduced distortion and better spatialization of sound, offering a more coherent soundstage.
Despite their compact size, the 6" woofers in AsciLab C6B loudspeakers are capable of delivering powerful, well-defined bass in spaces of up to 25m². Alumina ceramics provide exceptional rigidity for faithful, distortion-free reproduction, even at high volume, thanks to a strong limitation of cone deformation at high sound pressure. High-performance and dynamic, these woofers also come with an aesthetically pleasing protective grille, combining performance and design.
AsciLab C6B speakers feature a passive radiator at the rear. This limits unwanted resonance while optimizing low-frequency reproduction. This solution also helps reduce distortion at high volumes, unlike a bass-reflex port, which can generate turbulence. AsciLab has also chosen to integrate a passive radiator in order to maintain a relatively compact speaker design.
