I gave them all the ADA-1000-2 had. It was ridiculous for my 1920 cu ft living room but not for my 4200 cu ft space. My living room was quaking like I had 800xfour subs in it. Then I baked them good with the ADA-1500-2 in my main 4200 cu ft room. I kept turning it up more and more...I could smell voice coil adhesive and cross-over...LOL! I was worried I'd ignite them. Ian told me to keep on going. I got worried and stopped. By that time, the HP woofer was fibrillating and the dustcap was 7 degrees above ambient. I'm sure it was a few hundred degrees at the coil. This was all without a sub. They sounded totally normal after all that.
Just like every other Axiom, I tried ripping the woofer and mid-woofer apart by playing well below the rated frequency. I am talking Bassotronics. And LOUD! I could make them sound bad due to port noise and driver distortion but I couldn't damage them. Once I kicked the 800 in, they sounded totally normal.
