Tang Band W5-1138SMF 5-1/4" Paper Cone Subwoofer Speaker
Tang Band W5-1138SMF 5-1/4" Paper Cone Subwoofer Speaker is rated 4.8125 out of 5 by 16.
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.

Rated 5 out of 5 by from Excellent service.I'm in the process of making a loudspeaker system with this Tang Band sub-woofer with a pair of small 3 1/2 " full range drivers and class D amp, which I had purchased a long time ago from Parts Express. Not yet started the project, but after I'm done I'll remark about my experiment.

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

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

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.

Will these speakera fit in the rear deck of a 99 bmw 740i

Asked by: Erwin
This is considered an oversized 5-1/4" and actually measures slightly over 6". You will have to measure the existing opening and compare dimensions, but chances are this will require modifications in order to fit properly.

Are there 2 of these speakers for the $27 price? Or is that price for 1 single speaker? And do I need to run these off of an amp or can they be used like normal door speakers?

Asked by: Taylork21
The regular price if you buy 1, 2 or 3 of these is $28.84 each. If you buy four or more, the price drops to $27.40 each. A second amp is not required but it is recommended since these have fairly low sensitivity.

Hi I'd love to use this little sub with one of knock down MDF speaker cabinets.  I was thinking the 0.23 cu ft #300-7062.  Can some one recommend a port size and configuration for this arrangement?  Thanks

Asked by: Jbrawl
In that volume porting is not practical. You will have to use a pair of our 6-1/2" passive radiators with about 60 grams added to each for a tuning frequency of 45 Hz.

Hi if I was going to build a small bookshelf speaker using this woofer what would be a good tweeter for this and crossover thanks

Asked by: rotel86
I would not recommend this woofer for a two way design, it has a very limited upper frequency response. Finding a tweeter that will cross low enough is possible but can be costly. One of the only options we have that would work with the proper filter would be the Dayton Reference Series tweeters.
