Tang Band W5-1138SM 5-1/4" Neodymium Subwoofer
Tang Band W5-1138SM 5-1/4" Neodymium Subwoofer is rated 4.2923 out of 5 by 65.
Rated 5 out of 5 by from awesome little beastI had been going through some of the builds in the project gallery when I happened across a couple portable boom box ides. As a full time audio tech and repair technician I spend most of my time designing cool stuff to build in my head. I often find myself in the wood shop with my cnc cutter building my latest sub-woofer idea or pa speaker design. Not being able to get the idea out of my head I set out to design my portable, slightly over the top boombox. I have built many sub-woofer cabinets of many different styles from giant horn sub-woofers for pa application to smaller font loaded home stereo subs. I have built many over the top car audio subs for sheer sound pressure...so my expectations of this little speaker were not high.I spent some time looking at component choices to build my portable boom box and this speaker met the basic requirements and size to fix my design. My design goal was for a battery powered portable with ample bass output for some back yard and in the shop use. Needless to say this little sub has put a big grin on my face. I am totally in my happy place. I am quite pleasantly surprised at this little marvel.I settled on a .5 cu ft box tuned to 44Hz. I am hearing some frequencies well below tuning and this little speaker sounds much bigger than it is. I turned it on and my jaw just about dropped to the floor. The bass is tight and articulate and hits well below 40 Hz. So happy with this thing I couldn't wait to post a review.Still have all the finishing to do. I still waiting for some parts... sounds good enough for testing with.

Rated 5 out of 5 by from Tang Band 5-1/4 Subwoofer in a Bandpass BoxThis little speaker is an unexpected surprise! I used this to replace the BA computer 2:1 sub in a bandpass setup. I had to square off two opposite sides of the speaker's basket to make it fit, so I knew I better like this. This completely surpasses ANYTHING that old BA 'Woofer' could ever play. This sub resides on the floor, and after adjusting all my boost setting lower, you can still hear/feel the surrounding low frequency with absolutely no distortion. Yea, it's a keeper.

Rated 2 out of 5 by from you get what you pay forI got this unit to replace a 5.5 inch sub that came stock in a Pontiac Fiero. I had to build a mounting plate to adapt the speaker to the enclosure opening. The speaker is ok for the money I guess but I was disappointed with the rigidity of the frame or centering of the voice coil in the magnet gap as received. The cone was not centered and the voice coil seems to rub at above low volumes. I'm not sure if the bolting distorted the frame or if it was just never centered properly. I have built several home speakers using JBL pro drivers and they are quite sturdy. Same thing for some Diamond Acoustics speakers I have mounted. I don't know of any smallish subs that are made that are really good units. I expected better from a $70 speaker though.

Rated 5 out of 5 by from Great bass driver for a 2.1 setupI originally wanted to use a similar 6.5" Tang-Band subwoofer, but the price on the 5.25" neodymium model sold the deal. WinISD suggested roughly a 0.36 cubic foot (10-11L) box, similar to PE's recommendation, but I ended up going with a slightly larger enclosure (12x12x12-inch external) and reducing the interior volume slightly with dense foam for about 0.50 cubic foot.Combined with a 2-inch diameter port at a rather longish (and folded) 20 inches, I get reliable performance from 35Hz on up, with a 1.5dB peak centered at 38Hz. Rather impressive to hear a driver that small go that low. I paired this driver with the Dayton 2.1 Class-D plate amp that PE also sells and ended up with a complete system that both looks and sounds quite nice at a very compact size.

Rated 5 out of 5 by from What an Excellent Subwoofer!!!I had blown out my stock Bose subwoofers in my Nissan Pathfinder. After hours of research and reading reviews I decided to purchase two of these subwoofers. I paired them up with a Kenwood 60x2 amp and I'm very impressed. These subs kick out some amazing bass in the stock Bose enclosure. The bass shakes the truck. I'm a big bass head and these are no 12" subs but for their size they are amazing speakers. They deliver the right amount of bass fill that I was looking for. I would definately recommend these. They are a little pricey but you get what you pay for.

Rated 5 out of 5 by from Low Sensitivity But Very Low EndI have bought this subwoofer previous year without expecting much.First I builded a 4th order bandpass it wasn't a great succes.when I read the Sheet again I saw that the "Le" was very high so i started to find out if the sheet was right. It wasn't, if requested the 10khz impedance to calculate the "Le" and then there was a totaly different number, so I contacted Tang band by email and i said that the specs aren't right so they remeasured the driver and indeed. in stead of 25mH it is 0.17mHwith the new specs i have build a ported box 8 liter tuned on 45Hz (very low group delay only 12 ms max) it became a Excellent music subwoofer but it didn't go low enough only 32 Hz (-10db)finaly i've got my perfect subwoofer it is a t-line box with a 1/5 taper tuned on 36-38 Hz with a good low end 30Hz(-3db) 24Hz(-10db) and i was like 0_0 is this the sub that i have build or is someone joking with me.after a half a year i'm still enjoying my subwoofer.my opinion about using a 25wrms amp that it isn't enough. this driver can put a amplifier like that on his knees. i'm using a plate amp from the klipsch sub8 100wrms bit overkill but it does the job very well.I'm combining this sub with a Klipsch HDT500.if you're not a SPL head but a SQ head this is the way too go

Tang Band W5-1138SM 5-1/4" Neodymium Subwoofer

Ported vs. non-ported enclosure

Hi. Aiming to get the best bass possible out of a very small .172 cubic foot enclosure volume and wondered whether you would recommend this 5.25" sub with a ported or a sealed enclosure (or is my volume just too small to get good bass out of this?), or should I go the route of the 3" tang band sub with ported or sealed (assuming it requires less air space/enclosure volume)? If going the sealed route, I will of course use polyfill. If you recommend ported with either, what size port do I need? Thanks for any help.
Asked by: nitsudg
The Tang Band W5-1138SM 5-1/4" Neodymium Subwoofer is an amazing product for it's size and cost, making it an even better value.Your question of a sealed or ported enclosure is truly subjective. If you are building your cabinet and have good woodworking skills, I prefer a ported and tuned enclosure, but if not, then you will receive good sound from a non-ported or sealed box of proper size.A sealed cabinet will be strong and provide a tighter low end with solid transient responce while a ported enclosure will go a little deeper and be punchier with less applied power than a sealed box. I have a DIY system that is actually 2- sub woofers in 1 box with 2 chambers. One chamber is a similar speaker to the Tang Band W5-1138SM and it is sealed, the other is ported and contains an Eminance 15" down firing with a front tuned port. I added a good sealed back mid and ribbon tweeter for clean mids and highs. This speaker has punchy deep slammin bass, smooth mids and transparent highs. The point is that I designed around my taste and I love it. HOWEVER, an audiophile friend feels it is not as accurate as it should be. Well accuracy for him bores me. I like everything from metal to jazz fusion and even big band music recorded well. I like it exciting.Build to what you want to hear and you will always enjoy your DIY, don;t consider other's ears because you are the expert.ENJOY! Good Luck

Would this be a good choice to take a MTM w/ 5-1/4" mids and make a MTW with a three-way crossover instead of two? Pros, Cons, anyone?

Asked by: Psykodad
I've used the 6.5" and 8 inch versions of these neo motor woofers and they are absolutely amazing!the 6.5s are particularly incredible as they have very clean and clear midbass (up to 500hz or even higher) and I've even used them in 2 different ported applications and with the right tuning they're able to reach 30hz with plenty of authority!if you want some killer 3 ways I suggest using these as the woofer. I suggest use sealed if there's a subwoofer planned for them to go with, use ported if they're going to be on their own. for the 5 1/4 port to maybe 43hz, for the 6" port to 33 or so. you won’t be disappointed.as for using them in an MTM that's going to be tough maybe. if you look at their spec sheet there's some pretty back breakup happening before 2khz which is about as low as any tweeter will go. its doable but there will be noticeable peaks and valleys up in the 1-3khz area which could bother some people.these are primarily meant to be mini subwoofers or used in 3 way applications.

enclosure design

i have an enclosure built that is .41 cu. ft. for a single driver. i would like it to be ported, but i dont know what size to make the port or if my enclosure is too big. i have the ability to add a "devider" to section off the sub chamber if it is too big. i am trying to get it to play the absolute lowest freq. possible.
Asked by: rap700r
When I plot this driver in WinISD, it gives an optimal sealed enclosure for one driver at .222 cu. ft. with a frequency response curve all the way down to 10 hz. It appears to max out at about 200 hz. The vented enclosure ratings are completely unreasonable for this driver from what I'm seeing. Your best bet would be to go with sealed. It's calling for a 51 inch vent at 4".

put these in the back doors... smart idea?

HI allI am looking to add some low end to my car stereo system.One idea is to put the TB W5 speakers in the back doors of my car. These are the dimensions:Diameters:Front: 16.5-17cm (6½")Rear: 13cm (5¼")Depth Restrictions:Front: 60mm (2¼") *note this can be increased to 76mm (3") see fitting guide below.Rear (3-door): no restrictionRear (5-door): 70mm (if factory plastic rear cover is removed)It is already a small car so I do not want to spend space on a box anywhere. I have not seen anyone build a sub in a door... is there a good reason to not do that?What kind of amp would be suitable for this? I am not looking for any earth shattering bass, just some nice addition in the lower end. I could imagine as well treating the door would be more important with this use.. right?Input and or alternatives appreciated!Tnx!
Asked by: ErikB1971
Unless they are in a small enclosure the doors are nortoriously bad for getting low end. I would recommend putting a pair of these in the trunk in about .3-.4 cubic feet sealed. This will help the bottom end and not take up much space at all.

I would love to have two of these in one ported enclosure, I wouldn't mine if it was tuned a little bit higher, perhaps around 45-50hz, and really push the size to be as small as possible. Can someone help me with interior volume, and port size?

Asked by: torclausen1
I would recommend 0.7 cubic feet total with a 3" diameter port that is 10" long for a tuning frequency of 49 Hz.

Hi I am planning on building a subwoofer with this model and I was wondering if the 70w amp sa-70 is too much for this woofer.  

Asked by: Steph1985
The SA70 is a perfect match for this woofer.
