First impressions: not a lot of it, and kind of a weird mid bass bump. I could live very comfortably with an early drop off like my Chapman monitors. I'm not happy with the texture of these yet. I need to play with positioning a lot more, and there's a pretty good chance these will find themselves in a ported cab eventually too. I really want the Audio Nirvanas to work. I love the design concept, and their efficiency would pair well with a 300b amp in the future.
