zcon or hdc4

[Slobalt]

ok, for the op.... imo it would be win win for either sub.... imo the zcon is cleaner than the hdc4 and is quite beastly, but the hdc4 is a monster on the lows... I had 1 12 on a kx2500 and the thing wanted to open my rear doors from the trunk....

zcon- clean and powerful.....

hdc4- not as clean but monster on the lows and loud as all hell, just not as musical....

either is a great choice... guess it depends on what your going for... im sure you would be happy either way... I regret to this day selling my hdc4....

oh and my box wasnt that big either had it in a 2.2cu or around there lol box was made for a sa12... lol tuned to 33hz and big krit wanted to tear my car to pieces....

I went with the zcon and can't wait to get it but I went with it for many reasons one being what you said.

Where can I find a pair of 12s HDC4 ???? Anyone know

3 second wonder cars have NOTHING to do with daily set ups/musical vehicles...

Yes they are very different but I would think that the efficiency of a sub would still play a big part in both

just so you know they rerated the hdc3 to 1500...

that is true, i forgot about they changed the rating

Not for the vehicles that were mentioned as those guys run crazy power. For a power limited class then yes it would make a difference...

In which 4" coil subs are more efficient than 3"?

Have one of the guys you mentioned play music for a few minutes, see which coil they prefer then //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

They don't have them yet does anyone want to part with theirs....?

I would if I can figure out how to ship the thing.

 

[a1mcalister1]

How many do u have?

Of course if your objective is just to see how much thermal power a woofer will take before burning up, a heavier coil is better. That seems to be what the market demands. How loud it is will be secondary to being able to brag about how much power to took you to get there. So the same exact sound pressure is better if it takes you 1600W to get there than if it took 1200W. I suppose if your goal is to brag about "how many RMS" my subs take, 4" coil sub that you could jump up and down on the cone is superior.

This response makes the guys you mentioned even more senseless. Do you know how much power they push to a sub????

It was just a hypothetical reference, that makes sense.

Precisely. Which is why I say that efficiency gains from the smaller coil outweigh the ability to throw more power at it.

In which 4" coil subs are more efficient than 3"?

Basically all of them.. Especially since everyone here runs 1.5-2k to most of their wooofers. Power compression is a ***** and the extra weight of the coil is more than offset by the extra coil in the gap creating more motor force. There is NOTHING magic about a 3inch coil. We could all go down to 2inch coils for better effeciency if smaller coils were really better.. They aren't, they make for lesser BL numbers all things equal and in the long term handle significantly less power.

3inch coils can be built to handle large amounts of power, but the tradeoffs they general make to do so arent' always acceptable. That's why most "big boy" 3inch coiled woofers sound like crap. Much easier to make a musical 3k handling subwoofer using a 4inch coil than a 3inch coil.

My current subwoofer uses a 6inch voicecoil.. Bl^re value of well over 300, so significantly stronger than any 3inch coiled woofer outside of a DDZ or something of that nature that sounds like crap and does nothing but burp and it's 96db/1w/1m at 1000hz (and yes it WILL play that high if you wanted it too)

Even companies like DD are moving to 4inch coils for their daily applications at the highest level, look at the 9900 series, IIRC, it's a 4inch coil.

The ONLY reason many big subs use 3inch coils is because with the proper treatements to the motor, (most of which make the woofer sound like **** for music) you can give a 3inch coil enough power for 3 seconds to run the suspension into xmax near tuning without frying the coil.. Once you hit that point, there is no point in using a bigger heavier coil. You just need very powerful magnet to make up for the lack of coil area compared to a 4inch coil, and a thick 3inch coil. Most companies top end line are comp oriented, or at least they mostly care how loud the woofer is below 60hz than anything else, so that's a perfectly fine application.. Doesn't make it ideal for daily though.
