Subwoofer Not Hitting All Notes

yes it is a DVC 4ohm. in have it wired as 8 ohms and it is running off my 4ohm stable amp. I tried to wire it different way but it still doesnt sound good. My friend has the same sub wired to 2 ohms running off a 2ohm amp and his does the same thing as mine. I just tired a L7 in there today and it hit everything high low and mid. it was amazing. I was 10 times louder than the pioneer. So i just think that these subs are crap.

If the amp is bridged on the sub and it is moving on certain notes, it is not wired out of phase.

subwoofer is not the problem...enclosure is 90% of the sound.

i tried 3 different enclosures all different sizes and they all sounded the same.  Its the subs

i bet all of the enclosures were prefab...still enclosure would be the problem...doesn't matter how many prefabs you try. Prefabs are not one size fits all...some subs require different volumes and tunings to sound the way you want.

if you have another system set up the same way with the same subwoofer then you could be correct that they are crap.  But I've personally seen the pioneer you speak of and it hits low, loud, and is pretty impressive for a pioneer.  Disconnect one voice coil and test it out.  Then try the other voice coil by itself.  You may have a bad coil.
