Well, here I go again! After a long worthwhile audition of the Dayton DVC 12", I have now decided to go on the hunt again. Not that I am dissatisfied with it's performance, I do however prefer the musicality of smaller subs.
This subs low end performance is impressive even though ran in a 1.2cft/Qtc=.85 sealed enclosure. Impact is great as well as overall volume. I do suspect that I couldn't push it to it's limits with the USB 2150, but that definitely didn't seem to be a problem. Even when fed up to 2 volts on the inputs; I actually had to turn the gain down so as not to override the rest of the system. Overall, a loud, clean, sub well worth having.
My next project will include another of the Dayton Loudspeaker family. As of now, the Titanic MKIII 10" is on sale for $125. What primarily draws me to this one is the 400rms (which should mate well with the USB 2150's 450 @12.9 volts), along with 18.7mm of throw (one way!).
The use of micro enclosures is another plus that I am looking at (.40 for sealed f3 @ 53hz/ vented .70 f3 @ 32hz). The sealed is impressive with a .707 Qtc, which size is usually reserved for 8" subs. This was not the case for the 12 DVC. Even though it is a excellent performer, it is rare to get a 12" to perform in a smaller than a foot enclosure. I want a more stealthy install and so I opted for one even smaller.
I'm talking with some potential buyers and as soon as the deal is sealed or before the MKIII goes off sale, I will order one. I will give my reviews of that one as well. It is possible a custom fitted fiberglass enclosure will be in the plans for it, as I have long thought about building one to save even more space. I just needed a space-saving sub to use. No promises on that one though!
I'll keep ya updated.

Good info and a very qualified review on your part too... CLAP
That Titanic MKIII 10 looks like a very good steath sub option. Power handling is remarkable for an SVC type sub, but what the hey, it's 2.5" in diameter. That's getting close to what we see in Pro Drivers used in small wedge monitors.
Like the small box needs of this one too. Just remember it's 6-1/4" deep and may need some venting space too. Wonder how this sub would be in slightly larger sealed??? (.65 cf)
Comments on that one if you run a WIN plot for me?

Ok, I guess you should have a look at the specs of this 10" sub...

Ran through Win in a .65cft shows a 1hz f3 difference with almost similar group delay and phase plots. At 30 hz, still only a 1 db difference with the larger box having that gain. Not much of a tradeoff unless to control upper bass range. Still, in my eyes that is good since a small enclosure can be used with similar results.
As for vented, Win recommends .85 vented & tuned to 28.99hz. Of course port length will be a problem. You could get away with a 3" port, 24" length, with only a vent mach of .12. A slot vent would be better as well.

Looked at the CV V-max series sub and it definitely has potential in a small, ported box.
The F3 in sealed is pretty high... (~50 Hz.) A larger box will probably drop that closer to 40 Hz and this is always good.
Ported, this sub has and F3 of about 33 Hz. It seems to have a very linear slope below F3 and "flat above the knee". Not bad at all.
This sub can be had for about $100.00 USD. It is also a pretty strong sub in terms of design and materials used and only 5-5/8" deep. However, the vent hole is in the magnet too. So we need to allow some air space behind it too.
Thanks Victor,
