Tang Band W8-740P 8" Subwoofer
I am confused by the recommended box volumes and the reviews, questions and answers on this page. It seems like the specs call for a very small box, while people are sharing stories of making much bigger vented boxes. What's the deal? Optimum box?
There is no such thing as an optimal box. The application and needs are what will determine the proper enclosure for a given woofer like this. Tang Band subwoofers are notorious for requiring tiny vented enclosures and very long ports rendering them not very practical. To combat this you increase cabinet volume to maintain a lower tun which enables the use of a shorter port.

Does there happen to be a part number for repair kits for these? I have 2 of them that need new dust caps.
Unfortunately there is not a specific repair kit or replacement dust cap for these woofers. You will have to measure the diameter of the existing dust cap and purchase a replacement that is similar or slightly larger in diameter.

I have a sealed box with .15 cubic feet of space. I want the deepest sound I can get from it. I have up to 270 watts available to drive it. What would be the best driver for this box? The W8-740P seems like it would be a nice choice.
This woofer will work well in that volume as long as you keep it sealed. Depending on application, this will play into the low 40's in a home and low 30's in a vehicle.

I need an 8" replacement speaker for my Polk Audio PSW120 Powered Sub Woofer. I think this one might fit the bill. Any thoughts or input would be greatly appreciated. THANKS.
I would recommend the Dayton DCS205-4 for a replacement in this subwoofer.

Can you please explain differences 740P vs 1363SBF. Both are 150W rms. Would a larger enclosure around .35 cu/ft work better in a car?(better low frequency output, and they are prefabbed) RE - ZTX800 bridged for 1 sub. Front Dayton comp. Thanks
Both of these woofers work in very similar enclosures and provide a very similar modeled response. I would usually recommend a woofer with a rubber surround for a car application. These are both notoriously difficult to vent in a small box without a passive radiator. A 0.35 volume will be best suited keeping these sealed, in which case you can expect in-car response into the 30's. A vented box this small is not practical unless you can use an external port, but for either woofer in that volume the port would need to be 3" in diameter minimum and 40" long for a decent tuning frequency.

I would like to know the diameter of the magnet. I want to install these in a Miata and I have limited space where I want to put them.
The magnet is 6-1/4" in diameter.
