The Bose L1 Pro range is the current generation of L1 portable line array systems. Just as the L1 Model II eventually replaced the Model I and Classic, the L1 Pro system replaces the Bose L1 Model II, L1s, and L1 Compact.
The Compact is and always will be a reliable, powerful and super portable little speaker. Although it’s no longer produced or sold new, it’s great for small venues, smaller crowds (up to 50 guests), and perfect for DIY wedding hire systems, etc.

The newer Bose Pro8 portable line array has even more features: 3 input channels, Bluetooth, wireless control via mixer app, T4s and/or T8s input, and of course more bass, and more power.
