Got the Clarus drivers installed and I have to say ... I am very impressed with the sound quality.
The "Clarus" line retails for $550 per set, but the drivers were compared to the HSK 165 set from Hertz, which retails for $499 per set. It is an even comparison for speaker class. I would choose the Clarus drivers over the Hertz. The only downside to the Clarus drivers is weight - they are VERY heavy speakers. No way I would install them w/o the stock speaker brace. They are probably twice as heavy as the Legatia Pro SE divers, and the Legatia drivers are a 7.1" while the Clarus are 6.5". SQ on the Clarus is EXCELLENT - which makes me even more impatient to mount the Legatias!!
Eventually, the Clarus drivers will be moved to the lowers, which is where I moved the Hertz 165 drivers, so wieght will no longer be a concern. The Legatias will replace the Clarus in the fairing.
Not sure the if the same results hold true for the Imagine line, but I would not hesitate to get a set. I don't see how you could go wrong with either the HAT Imagine speakers or the Hertz HCX-165 speakers.
Hope this helps ... as always, speakers are VERY subjective so I would try and listen to both with your own ears and decide which sound better to you.
