Tang Band W4-1720 4" Underhung Midbass Driver
I plan to use these units in an MTM configuration with a Dayton electrostatic tweeter. Would you recommend a sealed or vented cabinet What would be the optimum size? What is the recommended crossover.
Cabinet volume would need to be 0.55 cubic feet for both with a 2" diameter, 6-1/2" long port for a tuning frequency of 48 Hz. A crossover cannot be recommended without knowing which tweeter you plan on using. Please email or call us with any further questions about the design.

Would these work well with Part # 270-018 tweeters crossed at 4500hz with a dayton two way Part # 260-148? I want to build a small sealed two way system for use with a 25w x2 t amp, will the tweeters have to much sensitivity?
This combination will work, although the tweeter will be a bit more sensitive. I would recommend padding it 4-6 dB overall for a smoother response.

My plan is a 2.1 speaker config, use semi portable system easily moved outside. 2 Tang Band 4” W4720 paralleled in each box, box pref not partitioned, + Goldwood GT-510 1" Tweeter, crossover 120-2500hz. Enclosure volume/ports what would you suggest?
I would recommend an enclosure volume of .65 gross, with a 2-1/2" diameter port that is 8-1/2" long for a tuning frequency of 47 Hz. Bear in mind two of these drivers in parallel will yield a 2 ohm load.

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.

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.

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.
