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

I'm thinking of buying this woofer for a diy sub build, and I want to put it in a Denovo Audio 0.67 cu. Ft. Box with the Dayton audio 25w plate amp. If I use this combination, what will the lowest frequency be?

Asked by: Cam39

How well will this driver work in a Push/Pull Configuration? Would I just double the recommended sealed? And is that .1 Cubic ft. or .2? If I arrange the drivers such that both are facing forward, I lose the Harmonic cancellation effect?

Asked by: mattr
This depends. If it is a standard push pull configuration the volume doubles, but if it is isobaric (drivers facing each other) the volume will be cut in half (0.11). I'm not sure what you are referring to with harmonic cancellation effect.

I bought the tri trix speaker kit and I'm not happy with them. Was thinking of buying the tang band Subs to replace the Dayton woofers. Then cutting the cabinet in half, sealing the cabinet and adding a 2 inch port in the back.

Asked by: Bthp
I would not recommend doing this. The Tang Band subs will not play well into the midrange to blend with the tweeter. If the Tritrix don't have enough bass for you, I would recommend using those Tang Band drivers as a dedicated subwoofer.

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.
