Peak output is calculated using "industry standard" techniques.
These calculation methods create theoretical specifications that are inflated over what can be achieved. BASSBOSS real-world output specifications are provided as "Maximum Sustained Output" ratings, which reflect actual measured, continuous output levels.
Sustained power is the rating at which your system can be run indefinitely. As a tuned and well-programmed system, BASSBOSS speakers are designed to operate at sustained levels for as long as you need to run your system.
