Tang Band W4-1720 4" Underhung Midbass Driver
What would the recommended volumes for sealed and ported enclosures be, as well as port width and length?
Looks good in .25 cu ft with a 2" port 7.75" long. Tunes at 60hz. It does come with a price though with a sharp rolloff below Fs. I would recommend a very sharp crossover slope if trying to play it below 100hz. Overall the response simulates very smoothly in my programs though.

can two of theses used per speaker with the Dayton Audio XO3W-700/5.6K 3-Way Crossover 700/5,600 Hz
In order to use two of this speaker with the Dayton crossover, you'd need to wire them in series to present an 8 ohm load to the crossover (and the amplifier). The low-pass section of the crossover can be used with 8 ohm or 4 ohm woofer setups, so your only options would be the series configuration for an 8 ohm load, or using only one driver per side for a 4 ohm load.

How about the smallest sealed enclosure for this driver? I will be using this in an outdoor portable system.
According to BassBox Pro, you'll want approximately 0.06ft³ sealed for this driver, which will put your F3 frequency in the neighborhood of 120Hz. For a more satisfying low-frequency experience, I'd suggest a 0.20ft³ enclosure with a 1" diameter x 3" long port, which will put the F3 closer to 60Hz.

how might this woofer perform in a setup similar to "The Stentorians" diy project?
how might this woofer perform in a setup similar to "The Stentorians" diy project? also, how do they perform at high volumes?
This woofer would be a good candidate for a similar project, however, I wouldn't suggest using this woofer as a "drop-in" replacement for the Stentorians. The differences would require a re-work of the enclosure and crossover. This product performs well at high volume; using six units per cabinet would be very effective at producing high volume.
