Has any one heard this thing before? I am sellin my hdc3's to get higher power handling subs. This monster caught my eye. I'll use it for daily on 2000 watts each with a comp every month or 2. Let me know what you guyz think?

Ive heard 2 hdc4 12's and i loved them. Got very loud and sounded very smooth not punchy like the hdc3's ive heard. Depends mostly on the install

I might be up to buy one of your hdc3s if you decide to get the 4s.

Well that's good I hope to have some more comments like this!!

I switched from 3's to 4's over the winter.

I've only played them loud on songs in the mid/upper 40's so far. Was good enough to take out another windshield a few weeks ago.

Seem to have plenty of punch to them on the rock/metal stuff I've played. I'll see how they do on the low stuff next weekend at a comp.

I run a 3500 at .5ohm on each one and they seem to take it just fine.
