Tang Band W3-1876S 3" Mini Subwoofer is rated 3.875 out of 5 by 8.
Rated 5 out of 5 by from Lil sub with a Lil punchI bought 2 of these with 2 tang band 3 inch drivers and hooked then up to a amp (200 watts) quite shocking the bass from them but the box has to be.pretty much perfect otherwise they will sound horrible.

Rated 4 out of 5 by from Caught me completely off guard.I picked up a trio of these from a member on the TechTalk Forums. I have always been intrigued by these drivers, but hesitant to experiment given the price. So when the right deal came along I picked them up.Once I got the drivers, I took a look at them and was pleasantly surprised by their sturdy construction. I boxed them up and forgot about them while I moved.Tonight I was unpacking some other parts when I realized that I had a shipping tube about the same diameter as the driver. Turns out it was 1mm smaller than the cutout diameter of the driver. I quickly soldered some leads to one of these Tang Band drivers and stuffed it into the tube, using some putty to seal up the hole where the wires went. The tube is capped on the end with a hard shell and stuffed with foam at the end. I estimate internal volume at ~.12 cubic feet.I hooked it up to the only thing readily available (a lepai 2020) and fired up some music. My jaw hit the floor, the amount of bass is incredible when you keep in mind how small it is. Even in a humble shipping tube this has usable output down to 50hz. It is definitely good enough for near field applications. I was so impressed I had to stop what I was doing to get on here to write this review.I have to echo the comments of others; there are more cost effective ways to get bass if you can spare the space, but when size counts, this will certainly fit the bill. At the same time though, don't expect tactile levels of bass, just a smooth presence of the low end.

Rated 4 out of 5 by from Good for small stereo in a small roomI bought this to suppliment a small stereo I had made previously. I used a .15 cu ft(260 cu in) enclosure and tuned it to around 47 hz and put a pair of FMOD 50hz high pass filters on he RCA jacks which ended up being imperative. Without the filters, when lower frequencies were played , the little sub would flutter violently and make helicopter sounds blowing air across the room through its ports trying to move enough air to make the unobtainable hz below 55 or so. The filter calmed the little sub right down and improved the sound of all the woofers. I tested its volume in this enclosure without the other speakers playing with only the 25 watt subwoofer amp(Dayton Audio SA25) playing the 3" sub and I got decibal readings at a meter away from the sub between 75 and 80 db which is fine for our small room application.

Rated 5 out of 5 by from Big Bass, Compact SizeI looked at these for some time as I have been working on a long term car audio project. Basically, I have built a MONSTER 12 speaker, 8 channel car stereo into a very small sport's car. It's taken almost 10 months to get to this point. The final piece of the puzzle was getting the low frequencies into the system.These tiny monsters were just what I needed and I learned allot along the way. First and foremost, due to their tiny size, you have less of a margin for error when it comes to building a proper speaker enclosure. I read some of the other reviews where people think these are rubbish, which basically means they didn't get their cabinet tuned properly. The spec's say this speaker need's 0.03 of Vas and they mean it. Not 0.0299 and not 0.031. When you have a speaker cabinet with a 15" woofer you can be off a some but not with these. There are lot's of websites with programs that will help you figure out how to calculate speaker box dimensions. Since I was building two tiny non ported wedges for under each car seat it was tough to get the numbers right on. But I managed to get the volume dead on at 0.031 and then found that a 0.5" x 0.5" x 2" piece of MDF board equals 0.005 of Vas. So I was able to step them up till the Vas was PERFECT and once you hit that sweet spot you know it. If you want to make it easy, make a box where every side is 4" x 4" x 4" interior space and you'll be dead on!0.001 off and the speaker sounds BLOWN. One small screw hole in the cabinet, the speaker sounds BLOWN. Once your cabinet is sealed and in spec the speaker performs like a Demon Midget. I also put batting out of an old pillow in side. I had to mess with the quantity to tune it a little tighter. I used a medium amount, not packed.I'm using two of these sub's in a small two seat car and it's punishing. Downloaded some speaker tests that go from 20Hz to 200Hz. They do their job, no problem. The Xmax on these are crazy! They're real sub's!

Rated 4 out of 5 by from L'il Bass-Boogers!This pocket-hercules does what it's supposed to- make bass in small enclosures. What bass it makes and how deep it goes depends on a series of tradeoffs:Power handlingXmaxVolume of boxLength of port or usage of PR'sI would honestly start with a 2 ltr box if you want to go vented, as that port gets long FAST. We're talking 11+ inches if the diameter is 1.2". And that only gets bass to about 55-60 Hz. This has a small bump for emphasis, and ~15-20W is ample power on tap.As you go up in volume, you can use larger ports, and/or the power handling will actually go down due to less air-spring from the box and easier mechanical excursions. I would think that if you're output careful, 4 ltrs would be the biggest I would go.(The Vas spec is not the size box you build.)It's a little insensitive meaning you need power, but it also won't take loads of it. It will work in the smallest of applications like no other bass-driver will. This is a one-of-a-kind piece. It does not distort as the vids online show- this is due to microphone compression or overloading. Value I gave a 3, as it depends on your goals. If you can't use a bigger box- THIS IS YOUR ANIMAL, and it's then worth the price. If you can go larger, there are other drivers that will apply. It will do bass and do bass well to about 45-50 Hz before things get more complicated, and it does what it is meant to do.Special apps and niche specs make this a great product for a distinct area of operation- good bass in a tiny space.

Rated 1 out of 5 by from DisappointingI bought this product with high hopes knowing that most tang band products are very high quality but such was not the case here. Although the sub looked very stylish it couldn't handle anyyy power so to speak of. So little power i don't know what this could even be used for. Defiantly would not buy again.

Tang Band W3-1876S 3" Mini Subwoofer

I was trying to put this subwoofer in a 3" sealed tube enclosure, what would be the recommend length of the tube, should i adjust for the volume taken up by the subwoofer, thanks in advance? 

Asked by: Snowboarder
If the inside diameter of the tube is 3", it would need to be 9" long for the proper volume.

Can anyone suggest a passive radiator (or 2) for a ~.07 to .1/ft volume enclosure on these? No larger than 4" on the PR(s). I'd be happy with 60hz f3. Part # 900-W3-1335A or # 264-1060 maybe? 1 or 2? Weighting on the PRs?

Asked by: loudvegas
One of the 3-1/2" Peerless passives would work well in 0.035 cubic feet. With no weight added you will have a tuning frequency of 60 Hz and an F3 of 66 Hz. In-room you can expect response into the 50's.

Is the .03 cubic foot ported suggestion in the specs accurate?  I see other suggestions for .1 and grater.  If .03 is accurate what length of .75" porting will achieve 60ish hz. If possible?  This is going in a 3" tube design.  

Asked by: loudvegas
Yes 0.03 is considered optimal, although this driver really works best in a larger volume. With a 3" ID tube, i would recommend a length of 11". W 3/4" diameter port would need to be 8" long for a tuning frequency of 60 Hz. This will reproduce 60 Hz depending on placement, but the model shows just over 90 dB output with full RMS power.

What full range drivers go well with this sub for a 3 channel system in a single enclosure? What kind of amp board and filters would work well - in what dimensions?

Want to build sub box with (2)W3-1876s, (4)Peerless PR 3.5", Dayton SA25 Amp all in 0.169ft^3 slim rectangular box made with 0.5"MDF. 2 W3 infront, 2PR in back, 1PR on left, 1PR on right, and Amp on bottom. Any weights on PR? Enclosure size too big/small?

Asked by: AE74
This should work well. The placement of the PR's will not matter and you will not need to add weight. This will result in a tuning frequency of 50 Hz and an F3 of 58 Hz.

"In order to get the published F3 in that volume the port would have to be external. The recommended port dimensions are 1" diameter and 28" long." CAN THE TUBE BE FOLDED BACK AND FORTH?
