Tang Band W6-1139SIF 6-1/2" Paper Cone Subwoofer Speaker
whats the optimum enclosure for 2 Tang Band W6-1139SIF 6-1/2" woofers?
i'm extremely new to building speakers and i want to build a new subwoofer for my computer. im looking for some decent punch from a small package.
If you used reflex box (ported) with two drivers, the optimum box is about 0.8 cu ft, and you have -3db frequency at 41Hz. The port diameter 2", with 4-5/8" long. You may also use 1.5 cu ft box, then the -3db frequency can be down to 35Hz. Port dia. 2" with 2-1/4" long.If you use sealed box with two drivers, I recommend the box volume 0.5 to 0.8 cu ft. -3db Frequency will be about 65Hz.

Would this be a good replacement driver for use in an old 6.5" Bazooka Tube?
I own this product and I have put it in a series of enclosures. I have found that the best type of enclosure is in a conical form. For example PVC piping works great for an enclosure in any speaker, especially this woofer. So I do think it would be a good replacement. By the way this is a great driver if u have sufficient power and/or crossover. It can really perform.

Would this speaker work for The Boogieman DIY subwoofer with Bash 500W Digital Subwoofer Plate Amplifier?
No. The thiele-small parameters are completely different and the DIY kit would not meet the specs. Use the 264-832 (The Voice Coil Inductance (Le) is different and will effect the performance outcome - search "thiele small parameters box calculator" to plug in the different drivers to see each response curve.)

would these work as a woofer in a 3 way 0.5 cubic inch book shelf speaker?
I think it would be possible but it depends on the efficiency of the other two speakers in the system. This sub is very efficient and only runs off of 4 ohms so maybe your best chance is using resistors to dampen the output from the tweeter or maybe the sub (depending on the wattage of the tweeter). Resistors are very cheap and I would suggest getting pairs of many different loads and just testing each out and how they sound. Also keep in mind if you use a 3 way crossover it most likely runs at 8 ohms, so you will need a 4 ohm resistor to put on this sub for it to work in the 8 ohm crossover. This is fantastic product and I think if you pull it off it will sound great.

Optimum sealed enclosure for the W6???
What is the ideal sealed enclosure size for the W6 ???Can I go smaller than ideal and still get decent bass(50Hz-100Hz@ +/- 90 db) ???
Using WinISD Pro I found that the optimal sealed enclosure for this woofer is 0.25 - 0.3 cu ft. With that size you'll get a -3dB frequency of 67Hz, and a maximum SPL of 100dB with 50W input (its maximum rated input). To give you an idea of lower bass levels, 35Hz will be at 90dB with 50W. Also note that cone excursion will be well within limits with this box. It would take 110W to go beyond excursion limits at 20Hz.Under-sizing the box slightly won't have a huge effect. A 0.2 cu ft box will still have a -3dB freq of 67Hz, but there will be a 0.4dB resonance at 200Hz (which would barely be noticeable). A 0.15 cu ft box will have a -3dB freq of 69Hz and a 0.6dB resonance at 170Hz.If you want bass extension down to 50Hz, as you implied in your question, then you'll either need to use a ported box with this subwoofer, or you'll need to use a larger subwoofer.

would these work as a woofer in a 6.5in speaker cabnet?
Yes they would, as their response reaches far enough up in frequency and is fairly smooth, but the reduction caused by the shelving of the response above 1KHz will make them sound "distant".The real problem is their efficiency, which is quite low. You will likely find you have to reduce whatever tweeter you use with it by a great degree, maybe as much as 12db depending on the tweeter used.I think there are better alternatives.I'm making the assumption you mean to use them as the midwoofer in a 2-way system, thus my response bears directly at that assumption.
