I used to own a Def Tech system: flagship BP7000SC for fronts, CLR3000 for center, BP7001SC for surrounds, and Triniy for sub.
I really loved that system. I thought they sound awesome for music and movies, even when compared to Revel Salon2, B&W 802D, Linkwitz Orion, RBH T3, DALI MS5, and everything else I've auditioned. Okay, maybe they didn't sound as great like 100% of the Salon2 or Orion or KEF Reference. Maybe they were 90% of those speakers. But I thought they sound every bit as good and detailed as anything else. My setup sounded amazing to me even when I
compared them to all those world class speakers. In comparison subjectively.
They measured about +/-3.7dB on listening window on HTM review. So they were (are) NOT considered to be ultra-accurate speakers like Revel, KEF, PSB, Paradigm, Linkwitz, TAD, etc.
But they measured more accurately than a lot of other speakers like some B&W, Legacy, Wilson, Klipsch, Mirage, Martin Logan, Magnepan, etc.
If I had never been a member of AH or AVS or A-V-Revolution, etc, I would probably still own those Def Tech speakers and still enjoy the heck out of them.
Of course, I don't regret owning all the speakers I own now either.
That's my experience.
If AH measures the new Legacy and gets a FR of +/-6dB from 200Hz-10kHz, they will be continued to be labeled as "inaccurate" speakers for like forever.
If that does not bother you one tiny bit for the next 10 yrs, then there's no reason not to buy Legacy speakers. If you like them and enjoy them, that's what matters.
