DD 9518g upgrades?

[quote name='adulbrich']They are the stiffest subs I've ever felt. Ask @av83; how stiff they are.

Wayyyy stiffer than my Z. Can't even move the cones with your hands.

I asked them to be built to handle 7k+ free-air

Also, Shizzon said the amp does 20k on music, not the full 30k. It does 30k at .5 for burps[/QUOTE]

It's the tightest moving assembly I've ever felt. I can't imagine them failing due to mechanical issues on any amount of power before having a thermal problem.

Make sure all your connections are good. That sounds awful

Just me pushing the limits. I sat there and watched the volts drop. But took it to a shop that build alts and he showed me how when the bass dropped my pulley was jumping. So I replaced it and now I don't have that problem

So your belt was slipping under load?

Slipping? Yep. Now I wonder how the sx would sound with upgrades. As of now the and sub is in my as a tv stand. In a new apartment and I don't have an alarm "yet"
