The design has been around for over ten years with a few minor upgrades I heard the speaker several times and liked themIf you heard them and liked them, that is probably the most important aspect in selecting a speaker.
Not sure by what you mean about the design being around 10 years? Its a ported 2 way speaker - a design has been around for over 50 years and will most likely be used for another 50 barring any significant breakthrough in how we listen to speakers. I think the Usher and MA's you site are ported 2 ways too.
Now the drivers used in the other two are different but not the design. And just because they are more recent models, doesn't mean they will outperform the Hawks. They could actually sound worse to you than the Hawks. I would suggest you listen to these and judge for yourself rather than get hung up on how long a speaker has been around.
