Tang Band W5-1138SMF 5-1/4" Paper Cone Subwoofer Speaker
Tang Band W5-1138SMF 5-1/4" Paper Cone Subwoofer Speaker is rated 4.8235 out of 5 by 17.
Rated 5 out of 5 by from Excellent solution for small subs in autosoundI'm using these in the lower dash enclosures in a 2015 Jeep Wrangler as subs. For something this small that can fit in the stock enclosures, they produce a LOT of good clean bass...even with the top down.

Rated 5 out of 5 by from "Alot of Bass for a small Sub"I bought these 5 1/4" Tang Band subs to make a set of bass heavy bookshelf speakers that would destroy all others that any company makes off the shelf. Well I pulled it off & I ended up with something really special. These little monsters can hit so much harder & far lower Hz than the silly Dayton Audio - B652 6 1/2" Bookshelf Speaker set, it just totally levels them. I play them on a Yamaha - R-S201 2 channel 200 watt stereo receiver & with a Optimus - 10 -Band Stereo Equalizer & they can take the power no problem all day long. Excellent small 4 ohm subs that work perfect for heavy bass. You will not be disappointed with purchasing these bad boys. Believe the hype, plain & simple.

Rated 5 out of 5 by from Great little subI built a two ported boxes for two of these.Powered by a single technics buyout amp. I am very pleased withe the output from these subwoofers.They go surprisingly deep for their size.Compared to my store bought Polk 10" subwoofer these sound better in my opinion. Great buy for the price.I like them so much I may buy more to put in the truck of my car.

Rated 5 out of 5 by from WOW!!!!!!!!!!!!!!!!I bought this to build Paul's Voxel! Wow, super impressed how this small of a woofer can produce so much bass. I have it corner loaded and this thing thumps! It's obviously not going to rattle the walls but, it packs a punch! Will be buying many more of these!

Rated 4 out of 5 by from Great little SubTang band is not the most common brand, but every speaker I purchase is amazing. Don't expect 5in to shake your house, but it is impressive and super clean. The male connectors are slightly chincy and the only reason I don't give a 5 star. Mounting wholes do vary so be careful and measure each speaker. They seem to do best in a ported or 4 order band pass. If you are having reservations, know this sub is a great buy.

Rated 5 out of 5 by from Quality ProductI'm impressed with the build quality of this little speaker. It sounds good for it's size when powered properly and was a great replacement for my factory woofers which were rotted out.

Tang Band W5-1138SMF 5-1/4" Paper Cone Subwoofer Speaker

What is the ideal sealed enclosure for this driver? Would also some sort of resistive pressure release in the cabinet benefit also?

Asked by: mattr
The ideal volume is 0.1 cubic feet, but 0.2 will work well and drop F3 a few Hz. The enclosure needs to be completely sealed.

I am designing a compact subwoofer for near field monitoring purpose. I can't find the right off-the-shelf port that will fit. If I use just one Dayton SD175-PR 6-1/2" Passive Radiator, what is the range internal volume necessary to work well?

Asked by: Seanychen
I would recommend a volume of 0.27 cubic feet for this combination. With 40 grams added to the passive you will have a tuning frequency of 40 Hz and an F3 of 45 Hz.

I just ordered the neodymium version of this speaker, and then realized the ported box design I have calls for this ferrite driver. Are they close enough to be interchangeable? 

Asked by: NateJ
Generally speaking, yes. There will not be enough of a difference between the two to need to make changes to the design.

How well will this driver work in a Band-Pass design? What kind of size and Frequency response might be obtained?

Asked by: cooljohn
This would not be a very good choice for a bandpass design, the recommended chamber volumes are around 0.1 cubic foot each. This will be better served in a small sealed or vented enclosure.

W5-1138SMF 5-1/4" Sub, what means A: 6-1/8", B: 4-3/4" ? My opening hole cut is 5.75 inch &abox hight inside 7 inch. Plenty depth. Can I use also W6-1139SIF 6-1/2" Sub, A: 7", B: 5-1/2", C: 4 ? How much cubic foot sealed enclosure do they need?

Asked by: Puhans
This is in the 5-1/4" woofer category but the actual frame measures 6-1/8" in diameter. With the dimensions you provided, the W6-1139SIF would be a better choice.

I am going to use this sub in a box 20"x10"x10" with 2 Dayton RS100-4's but in the description it says sub is best in enclosure of 0.26ft3 ported but above you say "This woofer needs about 0.75 cubic feet to really work well ported". Which is correct?

Asked by: scooter13
I recommend 0.75 cubic feet if you want decent extension from this driver.
