Frequently Asked Questions
It’s designed to work with any keyboard, but you’ll only get the custom EQ profiles if you have a compatible Yamaha model.
It's good for the price, but lacks the refined clarity and extended low-end response of higher-end subwoofers – expect a more 'budget-friendly' sound.
Technically yes, but you'll miss out on the dedicated EQ profiles, and the power output might not be ideal for professional studio setups.
