I think the part about the power handling is pure BS. A single 2 ohm coil
will handle more power than a single 4 ohm coil, but they are deluded if
they think it will handle more than a dual coil sub.
Taken from the spec sheet on their own website, they list the power handling
and box sizes as being the same for the 2 ohm and 4 ohm version of their
subs. They can't even adhere to the crap they're spewing out.
The issue of wiring is not really a fair one, since personally it is easier
to wire two 4 ohm DVC's for a 4 ohm load than to run 2 2 ohm svc's in
parallel for a 4 ohm load since with the dvc's there is no need to run any
wiring between the two chambers.
So basically, I have no problem with a 2 ohm sub. It can make wiring easier,
but not always. If there was such a big difference in the power handling
then everyone would be using 2 ohm subs. Just my 2 cents

But that refers to single coil subs. A single 2 ohm sub and a
dual 4 ohm in parallel for a 2 ohm load will behave almost exactly
the same. There will be some differences because of the extra
resistance and mass of the second coil on the dvc sub, but they
will work the same and sound indistinguishable from each other.
Paul,
Please reread the snip from Boston Acoustics. In the very first
sentence, it states that it is comparing a single 2-ohm voice coil to
a dual 4-ohm voice coil. The key is that the 4-ohm is a dual 4-ohm
that when run in parallel will yield a 2-ohm load.
I could paraphrase what Boston Acoustics said, but I don't see the
point. If you would be so kind as to revisit the argument, I would
like to hear your take on it.

Well, I see that everyone seems to say that there is no
difference. I am not one to argue because I don't know, but I
did find this snip at the Boston Acoustic's web site:

2-Ohm Subs vs. Dual Voice-coil Subs
When comparing a dual 4-ohm voice coil wired in parallel
(yielding a 2-ohm load) to a single 2-ohm voice coil, the single
coil will handle more power. As previously stated, the windings
on a 2-ohm coil are of a larger gauge than a 4-ohm coil. This
fact does not change in a dual voice coil subwoofer. A smaller
gauge is a smaller gauge no matter how many coils are used or how
they are wired. Dual voice coils also increase inductance
compared to a single coil, resulting in higher distortion.

This make sense to me. Is Boston Acoustics simply blowing smoke
or is this true?
