Classic L4³ – meeting pod for 8–10 people | SoSilent - Black / Plus (32±3 dB) / 2x glass wall + 2x soundproof solid walls

SoSilent Classic L4: The XL room for team collaboration and workshops

The SoSilent Classic L4³ is a spacious XL solution that offers space for up to 12 people, making it the perfect replacement for permanently installed conference rooms. It was developed to offer large project groups, multifunctional workshops or boardroom meetings an acoustically shielded place in the middle of the office - flexible, modular and without structural interventions.

As the heart of our 3rd generation, the L4 impresses with its striking external height of 2350 mm and its solid construction. A decisive advantage of the Classic Line: We manufacture this box exactly to your individual special dimensions. This allows you to make optimal use of your available office space, while the integrated castors ensure mobility that conventional drywall walls could never offer.
