  1. Jesse

    Great product! Makes speaker building much easier!

  2. Lars

    Big WOW. Coming from plug-and-play class D amplifiers, this is a whole other thing! The AIO4CH works & sounds 10x better than my previous setups after easily/quickly applying some filters in the useful configurator app.

    Seller is also super helpful, answered my question within 10 minutes. Would buy this product again without doubt for other projects in the future.
