Tang Band W5-1138SM 5-1/4" Neodymium Subwoofer
Would it be possible to use four of these speakers in an isobaically mounted 4th order bandpass box but instead of using ports i could use passive radiators? When i say isobaric 4th order I am refering to the style of the polk C4
Unfortunately we have no way of modeling this type of enclosure using passive radiators instead of port tubes. Based on the model using ports, this is not a practical design using these drivers, as the box volumes are very small and port lengths are astronomical, with two 2.5" ports needing to be over 200" long. A standard vented box would be much better suited for these woofers.

When I model this in various tools the most consistent result for a sealed box is 5-6L F3 was in the low 70s. I'm trying to keep the box small (so sealed) but would like to get another 10hz our of it. Possible? Or do I need to go to vented?
The F3 will only tell you so much when it comes to what you can expect from a driver. Depending on application, I will generally look at the F10 number for a more realistic bottom end when room or cabin gain is applied. With an F3 of 70, you can expect the actual extension to reach the mid 40's.

Does it have dual voice coils?
This is a single coil driver.

which driver (probably full range) would you suggest in combination with this one in an 2.1 system?
Just about any full range driver we offer will work for this application. There are a lot of things to consider to make a decision, I would recommend contacting our tech department for further help. 800-338-0531 x1 or firstname.lastname@example.org.

Hi I am planning on building a subwoofer with this model and I was wondering if the 70w amp sa-70 is too much for this woofer.
The SA70 is a perfect match for this woofer.

I would love to have two of these in one ported enclosure, I wouldn't mine if it was tuned a little bit higher, perhaps around 45-50hz, and really push the size to be as small as possible. Can someone help me with interior volume, and port size?
I would recommend 0.7 cubic feet total with a 3" diameter port that is 10" long for a tuning frequency of 49 Hz.
