Tang Band W5-1138SMF 5-1/4" Paper Cone Subwoofer Speaker
Tang Band W5-1138SMF 5-1/4" Paper Cone Subwoofer Speaker is rated 4.7778 out of 5 by 9.
Rated 5 out of 5 by from Great little subs!I built a 65 pound jam/party/tailgate box with a pair of these and a pair of ND91-4's. It's powered by a Pioneer head unit that allows low pass switching directly to the rear speaker outputs (CEA2006: 12Watts p/channel). The ND91's run high passed @ 125hz. I'm amazed, my son is amazed, and my friends are amazed at the deep penetrating bass produced by these drivers on only 12 watts! I had a 4 channel 40 watt amplifier driving these speakers for a while, but the switching power supply I was using caused too much interference and drowned out the entire FM band. As soon as I can find a quiet power supply, the amp will go back in.The chambers for the subs are .46ft³ tuned to 35 hertz.These little subs are great! Couldn't be happier.

Rated 5 out of 5 by from Great Price for a Great SubThere is no going wrong with it at this price, especially for a Tang Band. I have it in a 0.43 cubic inch box tuned to 35 Hz with a 1.5 inch port and it sounds great. The amount of bass you get for such a small driver is amazing but i have to say, you will get port noise from a 1.5 inch port. Maybe its because i used a sewage pipe as my port but i think this sub is better of with a larger port.I have it on my desk for music and i think that that is what its made for. Movies good too because it does go low enough but something bigger won't hurt. Overall, a good buy.

Rated 5 out of 5 by from The perfect bass in a tiny package!This subwoofer is a serious bargain for the price, and boy, does this thing pack a serious punch for such a small subwoofer.I've had the Logitech z523 a few months now, but I was never really satisfied with the speakers, especially the subwoofer (can I even call it subwoofer in its stock form?). At first, I opened up the speaker, took out the grill, and put pillow stuffing. The speaker sounded amazing after that. Thinking to myself, what about the sub? I opened that up, stuffed it with pillow stuffing as well and tuned the passive radiator to about 38Hz. There was still room for improvement though, that's when I looked into the W5-1138SMF. When I received the sub, I immediately swapped it out, and noticed an immediate improvement in the accuracy of the bass. Best of all, the bass sounded punchy, but still didn't sound "impressive". Though, at this point, the speaker cabinet had a noticeable amount of flex. So I opened it back up, hacked up a few 2" wooden dowels, fitted the sub cabinet a good amount of bracing. When I assembled it back together, including the pillow stuffing, oh boy has the sound improved greatly. The bass was clean (sounds flat throughout 100-37hz to my ears). No distortion (unless if I turned it up loud enough to make the passive radiator bottom out), and last but not least, the bass goes down to about 33Hz. I never even knew a 5 1/4" subwoofer can achieve that low without a t-line enclosure! Keep it up Tang Band!

Rated 5 out of 5 by from ExcelentI just bought for of these to upgrade my outdate and worn out subwoofers in my 2000 740 e38, With a bit of fitting work and modifying the stock subwoofer enclosure and some tunning, I got these installed. I was originally looking to install 2 10inch jl audio woofer in the trunk, but these have more then fit the bill, mirror shaking bass when powered properly. I have 600 watts rms feeding 4 of these units.Great product, unreal performance from a 5 1/4 woofer, nothing else like it in the market at this price point

Rated 5 out of 5 by from Goes very low for its sizeI had very tight physical restrictions for the sub design. It was to fit under the seats of the 2nd row in my Honda Element. That meant rough 4.1"x16.6"x13.1". The real limiting factor after the tiny box volume was the height of the driver. There aren't a lot of drivers that are <4".That lead me to this sub. I put it in a .32 ft^3 vented box tuned to about 37hz. I originally took apart the stock sub and swapped the 6.5" for a Tang Band 6x9 sub, but it still didn't hit as low as I wanted. I put everything into WinISD to compare and this 5" driver was able to play much lower, just not that loudly.I am amazed at how low this driver plays for its size. It definitely outdoes the stock 6.5" driver in the OEM cabinet. I might take out the 6x9 and put another W5-1148SMF in the stock location.

Rated 5 out of 5 by from Good little beastIn a 0.5cu ft^3 slot ported box tuned to about 35hz. It picks up down to 25-27hz and has more than enough bass for my apartment. Hooked up to a Dayton 2.1 plate amp puts out 50rms at 4ohms more than enough since the box is a little on the big side for this sub. Its like a mini version of my RE Audio SEX in my car.

What size box would i need for three of these drivers in a single box tuned to around 30-35 hz for auto application 

Asked by: SubGuy21
I would recommend a 1.6 cubic foot box for all three with a 3" diameter port that is 8" long for a tuning frequency of 34 Hz.
Answered by: MattP
Date published: 2014-07-03

Do these need a break in period in order to reach their maximum frequency range?

Asked by: JKHill
All drivers require a break in period before the suspension settles.

need box size for two with port with f3 at 35hz thanks

Asked by: jason72
I would recommend a 0.835 cubic foot box before displacement with a 3" diameter, 15" long port for an F3 of 34 Hz.

I would like to use this sub in a .25 cu/ft enclosure, tuned to somewhere around 40Hz. What would be the best port dimensions?

Asked by: BobbyL
In order to tune to 40 Hz in that volume, the port would need to be 2" in diameter and 21" long. Obviously this is not practical unless you have space for an exterior port, so If you can bump the volume up to about .45 cubic feet and shorted the port to 11" for the same tuning frequency.

2 questions,

this is a subwoofer so why is it under woofers and how do i wire 2 of these and keep them 4 ohm?
Asked by: speaker freack
The word "subwoofer" is used for speakers intended to reproduce the frequency range below that covered by the woofer.There is no simple wiring scheme that will combine two 4 ohm drivers and stay at 4 ohms. The result will be 2 ohms (from parallel wiring), or 8 ohms ( from series wiring).

What size sealed box?

What size sealed box would be best?
Asked by: derek82
I would recommend roughly 0.2 cubic feet as a sealed volume for these woofers. This will provide an F3 of 73 Hz and an in room response into the low 40's or upper 30's.
