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.

Rated 5 out of 5 by from wow, wow, wowbpught this for the Paul Carmondy Voxel sub build-google it. Just about all the bass you could want and in a small foot print too. Lots of punch and can handle a good deal of output due to its large xmax.

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

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.

This SW in a 6x6x12" (ext dim) box (.123 cu ft with .75" thickness). Sealed or ported? Know its specs prob better sealed, but want max low extension at sacrifice of SPLs. Suggestions for porting? Could possibly go to 6x7or8x12" box, but no larger.

Asked by: fstop7
This woofer needs about 0.75 cubic feet to really work well ported. In the volumes you have I would recommend sealed.

Will this speaker work in isobaric setup front - to front?

Asked by: Zero
Yes it will, although this driver already works in very small enclosures and mounting them in an isobaric configuration will not benefit you in terms of sensitivity or output.

Assuming I build a sub enclosure using the recommended 0.26 cubic ft volume & tune to 35 Hz, what would be the port diameter & length (flared port...does not need to be standard diameter)?

Asked by: Jonifide 5
I would recommend a port that is 1-1/2" in diameter and 10" long for a tuning frequency of 40 Hz.

I have an enclosure (under car seat) of 0.33 cubic feet, using 2 inches ID bellmouth port, how long should the port be inside the enclosure (I can run elbows)?

Asked by: Poman
The recommended port length for this volume is 20" which will provide a tuning frequency of 36 Hz.
