AsciLab A6BBookshelf Speakers 500W 4 Ohm 82dB Black (Pair)
The AsciLab A6B 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 6.5” Purifi aluminum woofer, all housed in an enclosure with two Purifi passive radiators. The Purifi 6.5" passive radiators provide a considerable boost at low frequencies. The frequency response of the A6B goes down to 32Hz (-6dB). Their design allows for lower crossover points and reduced distortion, for an extremely clear sound reproduction. The A6B feature a fourth-order crossover at 1kHz, optimized via Klippel NFS, and support up to 500W of amplification. These premium loudspeakers are ideal for demanding audiophile or professional studio use.
AsciLab A6B: Tweeters optimized for controlled sound dispersion
AsciLab A6B 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.
AsciLab A6B: 6.5" Purifi woofer with aluminum cone
Despite their relatively compact size, the 6.5" Purifi woofers of the AsciLab A6B speakers are capable of sounding spaces of up to 25m², thanks to their powerful, well-defined bass. The aluminum cone ensures perfect low-frequency reproduction. It provides exceptional rigidity for faithful, distortion-free reproduction, even at high volume, thanks to a strong limitation of cone deformation at high sound pressure. Powerful and dynamic, these Purifi woofers deliver near-perfect performance.
AsciLab A6B: two 6.5" Purifi passive radiators for deep bass
AsciLab A6B speakers feature a passive radiator at the rear. These limit 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 two passive radiators to maintain a relatively compact speaker design.
AsciLab A6B: non-magnetic crossover system and precise adjustment
The materials used in the A6B crossover system are non-magnetic, to avoid any hysteresis effects that could cause energy dissipation and distortion. Furthermore, each loudspeaker is tuned using a Klippel NFS system, for precise rendering.
