Tang Band W3-1876S 3" Mini Subwoofer
Tang Band W3-1876S 3" Mini Subwoofer is rated 3.7143 out of 5 by 7.
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.

Rated 4 out of 5 by from Cute Little Monster!I bought one just for the novelty, but it's better than I expected, so I made the design for a computer. I built a sealed 0.027 cu. ft. box with heavy fill and an active bandpass filter from 55Hz to 150Hz and a 15W amplifier. It fills in the bass from a set of RS75-4 nicely without adding a high-pass filter to the RS75-4s.

Tang Band W3-1876S 3" Mini Subwoofer

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?

Want to build Tube Sub w/3" dia tube. How long does the tube need to be while using a Peerless 3-1/2" Pass Rad at other end? Same question w/4" dia tube. Powered by Mini Hi-Fi High Power 2.1 Class D Audio Amplifier Board 2x15

Asked by: ChrisRC
A 3" ID tube would need to be 8-1/8" long using that passive. A 4" ID tube would need to be 4-1/2" long for the same volume. This will tune the enclosure to about 60 Hz and provide an F3 of 66 Hz.

if I used the .03 vented box design could I run the port externally? and if not how would I determine the additional size of the box that would need to be added to install internally

Vented Volume 0.03 ft.³ Vented F3 52 Hz Is this right? F3 of 52hz in only 0.03 cubic feet of volume? Whats the vent diameter/length that gets me that? Is there a PR combo (say 2 peerless radiators)that can do that as well?

Asked by: jtciti
Yes it is correct, but the catch is the port length. In order to get this tuning frequency and F3, the port would have to be 1" diameter and 29" long (yes, 29"). In this case, the Peerless passive radiator would be a great choice. In the same volume with no weight added, it will provide very similar results.

This only plays bass right? And is there an amp that would work with this?

Asked by: Raul_G
This will work best for low frequencies only. As a small subwoofer I would recommend our SA25 subwoofer amplifier.
