Tang Band W8-740P 8" Subwoofer
I am a newbie when building speaker boxes and will be building a sealed enclosure for this sub. It states that the sealed enclosure should .11ft3, does include the volume of the driver already?
Hi, I want to build 2 boxes. One sealed, which you answer a question about, and one ported. I know the ports must be long with this sub, but what port size would you recomend if I built a 9x9x20" (0.60 cu ft) box and which PE port would you recommend?
The port for this volume would have to be 3" in diameter and 20" long. Unfortunately we do not have any ports that will work for this unless you purchased a Precision Port kit and added an extension tube. This port would have to be external.

I'm trying to get as close to 0.11 ft^3 as I can with a sealed box. What is the displacement of the sub (I assume that's not taken into account for optimal enclosure)? Also, what would be the response in a 10'X10' room in a 0.11 ft^3 box. Thanks.
This woofer displaces about 0.056 cubic feet. I cannot model it in a given room, but I can say that in that volume you will have an F3 of 80 Hz and an F10 of about 48 Hz.

I have a Vizio S5451W‑C2 54" soundbar 5.1 surround sound home theater in a box. Would this make a noticeable improvement in the sound of the 8" subwoofer included in this setup?

Can this sub be run in free air configuration? If so does the power handling change?
It can, but you will want to watch excursion. The power handling won't change but the driver will reach its mechanical limits with as little as 100 watts.

Thinking of this in a tower design in the sealed box portion low passed at 80-100Hz with TB W8-1808 in OB for the remaining ranges above. Would like to cross higher for the sake of the full range driver, but don't want to get boxy. Is this high enough?
The crossover point will have to be determined by listening tests. Generally when you get above~100 Hz the sub can be localized unless it is within close proximity to the full range driver. It will handle a higher crossover without a problem, but determining the final crossover point will be up to you.
