I replaced my old speakers which had a subwoofer with these new Kanto ORAs as I needed a higher quality speaker to better adjust voices in Premiere Pro, especially now that Premiere Pro has AI speech enhancement. My old speakers were too flat, and I required more dynamic range to get a true representation of voices with AI speech enhancement enabled. They call these “Reference” speakers, and they truly are for my application. I haven't purchased a subwoofer yet as I thought I'd see how they perform first, but after listening to music on Spotify, I decided that their bass is good enough that I don't require a subwoofer. For those with a sit down to stand up desk, the power adapter cable is five feet long. That is long enough for the power adapter to sit on the floor and the desk to rise to a high height without extending the adapter cable to its maximum length. My only gripe is that given the high price, you need to provide your own USB cable.
