Here's an idea but you guys insist on doing the 682drums conversion kit so you probably won't like it.
Quit trying to convert them with that kit which isn't necessary. Do Hellfire's method. My kit has the deeper shells and the shallow ones as I added an extra 12" pad in my upgrade. HF's method worked great. I also dealt with the different quantity of foam layers between my stock dm8pro kit and the 12" add-on pad and all pads trigger great.
Why do you guys insist on spending money on a conversion kit that isn't wise for the build of Alesis pads in the first place?
If you sit and watch Hellfire's video, he clearly explains how to make the stock Alesis trigger system work if you are switching to mesh.
After you guys spend the extra money and bother with the 682 method, I will glady compare my set to yours and prove you are wasting your time with that nonsense.
I am not trying to be rude or disrespect anyone by my comments but I know HF's system works great and the only investment beside the mesh heads was 2 bucks worth of Funky Foam. I just don't want to see you guys and future members get caught up in wasting money on 682s kit. Their heads are great as I have them myself.
You guys need to really take advantage of the knowledge dmdrummer vets have and listen to them as so many are wiz's about e-drums and are happy to help others. That's why I'm a member here.
Good luck.

Sorry to bring up an old post but I figured I'd address what Greg says here and my outlook on the set so far with the 682 conversion in the interest of full disclosure on this topic. Overall, I think the 682drums conversion with the cones has been adequate, especially on the 8" and 10" pads.
However, it seems pretty clear that the cones are too large for the 12" pads as stated by Hellfire. Overall, I would agree with you, Greg. It's been a while since I performed this mod and I'm not even sure what drew me to this kit in the first place; I think the conversion process appeared so simple and there was also the perceived allure of having a lot of empty space to allow the mesh head to resonate and reduce noise. But the 682 kit, at least the rendition I received, was hastily designed.
Now that I've been playing my kit a little more lately, I would say that this conversion works fine and is simple (though overprice) for the 8" and 10" pads, but if I could go back I would've tried Hellfire's conversion first. One of the 12" pads works fine because the 12" head from 682drums actually fits correctly; the other head simply does not fit right, and took and endless amount of centering while tightening to get close, messing with the foam cone and making the pad feel and look cheap. It actually seems to trigger quite effectively and reliably, but the THWACK from a cone hit and the pressure the cone is putting on the mesh head is leading the head to wear prematurely, and I bet triggering could be even better with the simpler mod.
I would honestly recommend Remo Silent Stroke, Billy Blast, Hart, or possibly even Roland heads over the 682drums heads from what I've seen around these forums, ESPECIALLY for the 12" size. Take that with a grain of salt though because it's been a while since I've looked into this and I'm not sure if the quality or availability of some of those brands has changed.
As for me, I'm going to convert one of my 12" pads using Gerdy's mod and compare it with the 682 cone conversion pad. I just received the speaker foam I need, and I'm looking forward to doing a comparison soon.
