I've never had such even, impacting, punchy, and clear bass.

The A21’s never sound harsh and it is great to work on these speakers during a long day’s session.

"In one short afternoon, I went through all of my songs and fixed all these covert frequency problems like it was a promenade"

More than once I heard people exclaim they sound so honest

“They sound like something I have never heard before. Everything was clear and upfront but neither silky or harsh!”
