If by comparable you mean similarly nearly-as-linear-as-an-active-speaker, then probably none. But plenty of examples with quite good linearity. I just think sacrificing dynamics for nearly straight-line linearity is the wrong compromise to make, unless it's solely for use in near-field use or will never be turned up very loud.
I'm not saying it's a bad speaker by any means, it's plainly very good. Just not my cup of tea. I understand not everyone values a speaker's ability to play dynamics without undue compression or distortion. And that's okay; it's okay to be wrong.
Like I said, I imagine the MTM version will do much better in these metrics. Hopefully it will have both incredible linearity and dynamic ability.
