How much power are you feeding them and what are your crossover settings?

That's odd. That's pretty conservative power.

How do they sound? My first thought is just a fad of mass production. Then I also thought they got wet and when played they stretched the woofer paper. when played. Contact GZ, send them this pic and see what they say.

I have to pretty much tune any kind of mid bass out to get them to not pop at higher volume. Other than that still loud and clear. Thought it was maybe dirty power from the b54 so I swapped it out with a sd800.4 and it was the same result. Contacting HKI and GZ is my next step.
