we've been talking about doing it for some time now, now why don't we do it!

What i thought, was we could introduce a question, or misconception, or something, and then each post a few posts discussing it... then we'd move on to another subject when the first was covered (and agreed on by everyone taking part). then i'd edit this post, and post a link to the page number of where the "second" topic starts, and what the second topic is.

To start out, i thought we could introduce the big hazy area of: What sub's better, a DVC or SVC (single or double voice coil) subwoofer, and in what regards?

since i introduced it, i'll let someone else start us off :)

Thats the Spirit ICE :D
These are my opinions Only> I am no expert on subwoofers. I have used more single voice coil subwoofers in the past than anything, all had 4ohm single 2inch voice coils and worked fine for each application i used them in.
The single 4ohm coils Limited my amps output to some degree but worked and sounded very well. The power handling on the SVC Subs was also limited.

I really like the 12inch DVC Dual Voice Coil subwoofers with dual 4ohm coils.
This allows me to use them in a variety of applications from Home Stereo systems to Car Audio.
I can wire the subs at 2ohms or 4ohms or 8 ohms, I use 8ohms for home stereo use, 4ohm setups for street use in car audio "continuous play" and 2 ohm for competition applications.
Changing the ohm load on your subwoofer "Tells" the amplifier how much power to shove to the sub, so the higher the ohm load that is applied, like 8ohms for instance, the less power the amp will push to the sub.

Matching your subwoofers to your amplifer is Very important, By matching i mean finding the Right combination of subwoofers and amps that will work well together. Mismatched sub/amp combos don't work well, you have to look at the "RMS" Power Rating AND "ohm" rating on both the amp and the sub for a good combination.

Enclosure design is another subject but it is also the 3rd factor and also a very important one that will decide how good your subs perform.

So I prefer DVC Subs over SVC Subs for the reasons i stated above, again this is just my opinion and it is what works for me. Great Thread :bouncy:

right. the only main reason (other than perhaps an efficiency of like 1 dB) is that DVC subs give more wiring flexibility

... as far as i know :)

I agree with the point that SOUND made. DVC definately allows more flexibility with regards to applications. Matching power is also important, which it is always to your advantage to have plenty of power in reserve.
