The Bose L1 Pro range is the new generation of L1 portable line array systems. Just as the L1 Model II eventually replaced the Model I and Classic, the L1 Pro system will replace the Bose L1 Model II, L1s, and L1 Compact.
The Compact is and always will be a reliable, powerful and super portable little speaker. Great for small venues, smaller crowds (up to 50 guests), and perfect for DIY wedding hire systems, etc.
