Tang Band W6-1139SIF 6-1/2" Paper Cone Subwoofer Speaker
Tang Band W6-1139SIF 6-1/2" Paper Cone Subwoofer Speaker is rated 4.75 out of 5 by 8.
Rated 5 out of 5 by from The David of subsI used a round drain trap from Home Depot and some RTV sealant to glue the speaker. I used an old MTX amp to power it. I needed a tiny footprint for my Mazda5 minivan and this worked great. It sounds as good as my Alpine 10" in my GTI but just can't go as loud. I never needed the Alpine to be that loud anyways.

Rated 5 out of 5 by from Nice little sub!The Tang Band W6-1139SIF worked out very nicely for a small bookshelf subwoofer design. I used a .5cuft enclosure with 1.5 x 8 inch port (f3 @ 31.4Hz) and the Dayton Audio SA25 25w plate amp. It blends very well with my Audax book shelf design at normal and higher listening levels. A definite needed improvement in the low end for less than 100 dollars!

Rated 5 out of 5 by from All Tang Band systemI purchased a pair of these along with a pair of Tang Band W2-748SG 2" Full Range Drivers Part Number: 264-861 and set out to build a compact system that performed beyond its size. I built these into two Knock-Down MDF 0.56 ft³ Bookshelf Cabinets Part Number: 300-7064, crossed over using 800 Hz Low Pass 4 Ohm Crossover Part Number: 266-448 and 800 Hz High Pass 8 Ohm Crossover Part Number: 266-470, stuffed each cabinet with 1/3 bag of Acousta-Stuf Polyfill 1 lb. Bag Part Number: 260-317 and ported the boxes with Port Tube 1-3/8" ID Adjustable Part Number: 260-388 set to 7-3/4" long. When I first hooked them up, I wasn't expecting too much, since I hadn't done any additional tuning. I was right - they sounded terrible. Bass response was awesome, but the mids were strident and honky. I decided to flip the polarity on the W2-748SGs and used a spray paint cap as an isolation chamber, glued inside the cabinets behind the tweeters. Fired them up with 2 watts of pink noise for about an hour and then decided to give them a go in the house. First, I disconnected one of my psb B-6 units and hooked up the home built unit. I was pretty surprised. The new box delivered a very clean sound that was a decent complement to the B-6 on the other side. Then came the acid test - both channels driving these puppies. The sound was a bit more forward than the psbs, but very believable. The bass response was every bit as good - perhaps a bit better. The soundstage was very well defined and extended far beyond the placement of the speakers. I may attenuate the high end by about 2dB to tame the forward nature, but it's not a huge priority since they do sound so good.I know - I committed a cardinal sin by mixing a 4 ohm woofer with an 8 ohm mid/tweeter. That's because all of the other driver characteristics were compatible. I wired them so they could be bi-amped if I decide not to put my amp on an impedance roller coaster. So far, though, no problems. I'm using an Integra amp that seems to be up to the task. Maybe I'll try them with the amp I built using a Sure 4x100W @ 4 Ohm TK2050 Class-D Audio Amplifier Board Part Number: 320-302.If you're in the mood to toss together a great sounding system, don't shy away from Tang Band. The speakers are an excellent value and provide very controlled sound in a manageable size. One note though, the W2-748SG drivers don't have any mounting holes (the PE description says there are 4 - it's wrong), so they must be press fit into the mounting holes and sealed appropriately.I've included a couple pictures of the speakers in prototype stage. I'll finish the cabinets with a piano-black lacquer (and I'll also make sure I have screws in all of the screw holes).

Rated 5 out of 5 by from Holy small speakerI used this speaker to repair my klipsch pro-media 2.1 sub. It sounded ok in the original box but had lots and lots of port noise. I built a new box that was aprox 1 cubic ft with a 7 1/2" long 2" port and the sound is outstanding. I'd have never thought a 6 1/2" speaker could sound so good. I am very satisfied.

Rated 4 out of 5 by from Tap it for deep bass!I used this subwoofer as cheap alternative for the tapped horn subwoofer project found online (Search for "Anarchy Tapped Horn"). Despite the driver's small size, the final dimensions are surprisingly large...but so is the resulting output! The enclosure fits behind your couch or tucked in a corner and will shake your picture frames unlike any 6.5" driver you've ever heard. At moderate listening levels it fills my 16x22' room nicely. The first real test was watching HBO's "The Pacific" and the mortar shells shook the room enough to send the cats and dogs running for cover. I chose to power it with a Yung SD100 100w plate amp. However, 100 watts is overkill for this subwoofer and I have the gain set below 50% after experiencing some bottoming out of the suspension. Overall this is a great buy and a great project. It's no replacement for a high powered 12" or 15" but it will trick most listeners into thinking something larger is hidden within the maze of plywood.

Rated 4 out of 5 by from Computer SubI created this sub to provide a decent near field subwoofer for my home desktop. More for fun, but I built this as well as a pair of small "buyout" filled mini monitors. I chose to build this without a port but might add one in the future. I used an online calculator to make sure I had enough volume to include with the stuffing and the 70 watt amp from Parts-express. I used a combination of Birch ply and MDF and added some Oak accents to parts of the box for looks. see pictures. In it's intended location it literally vibrates my legs, and with the satellites can fill a room twice their size. Was a fun little project

Tang Band W6-1139SIF 6-1/2" Paper Cone Subwoofer Speaker

I have slightly more than 1.5 cubic feet to work with and can go no larger than 6.5" i was thinking about running 4 W6-1139SIG 6.5Tang. Ported or sealed for most bass.  It will be in a small vehicle

Asked by: moose0011
With that volume I would recommend sealed. You will have a good amount of output down into the low 30's and the subs will handle full RMS power without a problem.

Could this be used in an IB setup like in the rear deck of a car?

Asked by: karfreek
Yes this can be used in an IB application, you will just want to watch excursion levels at lower frequencies.

Can I hook up these woofers directly to a car-stereo head unit without a crossover ? Answere in Simple English if somebody wants to help me!

Asked by: Olofen
Technically yes although they will not work well as a full range driver and you will not be able to use them to their full potential with the limited amount of power. These are best utilized as subwoofers with 50-75 watts RMS each at 4 ohms.

I would like to run 4 of these subs in a ported box with all subs sharing the same enclosure.  How many cubic feet and port length and width would I need to achieve a frequency of around 30hz?  I have asked this question before but I have lost the email. 

Asked by: LittleG530
Four of the Tang Band W6-1139SIF subs will work well in 2.2 cubic feet with a 4" diameter, 17" long port. This will tune the enclosure to 30 Hz and give you much more headroom in terms of excursion.

Has anyone tried these open air?

Asked by: Jakeloos89j
These will work okay in a free air application, you will just need to watch power and excursion levels below about 30-35 Hz.

Will this fit into a 2004 Wrangler center console?

Asked by: MikesJeep
Unfortunately we do not have specific dimensions for factory speaker sizes. This woofer measures 7" across the frame, so you will have to compare this to the original to see if it will fit.
