I did not know that. Is this a recent practice or has it always been so?
I rarely look at specs for anything audio beyond power ratings and then only to make sure I don't blast a VC across the room. Otherwise I don't care. Especially speakers. I use my ears only. I'll tell ya, it's saved my a lot of money over the years (but I'll admit, it's probably made me spend more as well).
As a fan of both tubes and solid state, specs just get in the way of having a good time. IMO of course.
I know a lot of people take specs seriously and use them in part to make purchasing decisions, and I'm not knocking that. Further, deceptive specs are just annoying and if they are lying about that, where else are they cutting corners?
All I can say is that the ones I have are bulletproof, built like tanks, and deliver a great non-fatiguing sound paired up with the Outlaw 750 5 channel amp. Before the Outlaw/B&K combo, the Pioneer VSX-D906S AVR made me think I had made a terrible mistake and they were as bright and shouty as the Klipsh or B&W but thankfully it turned out to be a Pioneer thing and not a DefTech thing.
Maybe the modern DT is a bunch of Ed Hardy clad douchebags that came over from Bose? I don't know. I'll never need another set of HT speakers. These are still doing fine.
