Okay so let me start this off saying these were project subs for my first recones. I picked them up dirt cheap and decided to give it a shot, now I'm asking for feedback from people who have reconed subs before.
Subs: HDC3 10"
Recone: Standard Dual 2 Copper Coil.
So basically I picked up two motors/baskets one for 20 local (CL guy was an idiot) and another on CACO for pretty cheap too. So I decided to give them a shot reconing. I watched a LOT of YouTube videos on reconing and did them step by step, cleaned basket/motor, shimmed, etc etc. Both subs play, coils read good, but the first sub I reconed has a tick audible roughly 900w or so. When really driving them it turns into a slap. The second sub is perfect no issues. My question is, what could be causing this noise? When I got the motor, it was not shifted, and I cleared the gap (could have possibly missed something but I doubt it). And when I press up and down on the cone I can't feel any rub. So anyone with any experience or educated guesses feel free to chime in. I plan on reconing this sometime in the near future and hopefully avoiding whatever might have gone wrong initially. Thanks guys!
