Tang Band W6-1139SI 6-1/2" Subwoofer

Amazing bass in a compact package! This one-of-a-kind 6-1/2" subwoofer has an impressive 13 mm of Xmax. A wide roll surround, raised flat spider, and large 1-1/2" 4-layer voice coil ensure impressive bass performance and high power handling. Venting the pole piece and spider allows good airflow around the coil, improving heat dissipation and reducing power compression. The compact neodymium motor structure saves valuable enclosure space while also allowing closer-than-normal placement to CRTs. The ultimate multimedia subwoofer driver!

Tang Band W6-1139SI 6-1/2" Subwoofer
Tang Band W6-1139SI 6-1/2" Subwoofer is rated 4.4848 out of 5 by 66.
Rated 5 out of 5 by from Great little thunder makerThis is another one of my favorite products from Parts Express. I can't even remember how long I've had this little sub, but it's 6+ years. In those years, this little W6 has been under my desk thumping and growling though music, games and movies. My enclosure is pretty close to the "optimum" ported enclosure recommended here, and I have always been impressed. I've also impressed a lot of people with this W6, who didn't believe that it could produce the sound that it was. It is a smallish sub, so it certainly has its limits. Work within those limits and you'll be a happy camper. I'm using a Dayton 25 watt plate amp, and have the low pass set to 60 Hz. So it's sole job is to sit here and rumble, which it has always been happy to do and never left me wanting for more low end on my computer 2.1 setup. Highly recommended, but would be nice if the price was less (like back when I bought it). Still want to try using multiple W6's in my car, I like them that much.

Rated 5 out of 5 by from OutstandingTried recommended sealded box first. It was mildly awful. It then sat on the shelf at the car audio shop where i work for close to a year. I warped yhe coil on my ultimax 10 and needed a sub so off the shelf it came. I used to have a DDsw65 in a bandpass and the output was amazing so i thought id try a bp for this spk. The TB is possibly the best sounding sub ive ever ran. 4dr civic, using the rear floorboard i made a parallel 6th order bandpass. 1.5cuft. -.75 each chamber. Front tuned to 42hz and rear tuned to 60hz. With each port running under front seats and firing into the front floorboard. The box extends all yhe way across floorboard and as high as the bottom of rear seat foam. I have two kids in car seats back there aso they dont mind the loss of foot room. Alot of peaple sit and listen, including audio professionals, and no one has ever guessed a 6 1/2. The illusion of bass in the front stage is no longer smoke and mirrors, its real!. If i rebuild the ultimax it will prob LPF at 40hz and get tuned to round 25 and only play the lowest of lows cause the TB has the main bass duties on lock!!

Rated 4 out of 5 by from Neo Tang Band 6-1/2" subwooferI'm glad this sub is available, but it seems selections of product of this type are very limited. So, I can't say this is the end all sub with respect to performance and price. You can't really find anything in the US of same size and magnet to compare it to. So, by default it is good and at the same time OVER-PRICED. I can buy an entire powered subwoofer for less, new on ebay. I just happened to need a replacement this size with similar characteristics for a favorite subwoofer I own. I would like to see Parts Express catalog some other options so people would have more choice in a neodymium sub this size.

Rated 5 out of 5 by from Great little wooferSurprised by this small little woofer, it really hits hard & without any distortion. I'm using Bash 300 to push the woofer.No regrets!

Rated 5 out of 5 by from If onlyI bought these to be mounted in my doors of my car, and they were too deep, I looked at the measurements (which are correct) but I thought I could make it work, and apparently I was wrong, but having bought them from PE they took them back and sent me a different pair very quickly. These things are built like tanks, and I really wish I could have ran them. I ended up going with the Peerless HDS 6.5's with the GFC cone, and am happy with those, but these things would have been awesome for getting down low.

Rated 4 out of 5 by from Very impressedI just finished a sub box with the W6-1139SI, sealed 6.55L with the Yung SD100 amp. I’m playing a Sigur Ros disc through my laptop and I’m hearing bass that should not be coming from that size driver. I built the RJ Projects ported cube first and though that too impressed me I like the sealed box I designed better. I’m very happy with my purchase.

Tang Band W6-1139SI 6-1/2" Subwoofer

Looking to build a simple 2.1 stereo setup using a tda2030 amp kit which will provide 36 watts to the sub channel, would that be enough to drive this sub or should I look for a sub with a power handling closer to my amp's max?

Asked by: danstinebaugh
36 watts will power the sub but not provide much output. The wattage isn't what you need to worry about, I would look into getting a woofer with a higher sensitivity. Something like our Dayton DC160-4 would take that wattage farther and still work in similar box volumes.

I own two of these drivers but only planned to use one in a ported enclosure. Then it occured to me, why not use one as a passive radiator and avoid port issues. How big of an enclosure should I make? 

Asked by: Arieleno
I would not recommend using one of these as a passive radiator, there are a few problems with this. There is no way to model or tune a dummy driver like this, so your end result will be unknown and probably tuned too high. Also, since the surface area is the same for both, the passive will be over driven quite easily. You would be farther ahead using both wired, or simply using one as originally intended.

Difference between the SI and SG?

Asked by: BCM90
As far as I can tell, the SG is either an older version or a model Tang Band built for commercial products like the Logitech computer speakers.

I would like to use two of these W6-1139SI subs in your Dayton Audio MTM-0.75BK 0.75 cu. ft. MTM Speaker Cabinet should i port it or leave it sealed and what do you recommend for a amp

Asked by: cadillacman50
I would recommend porting that volume, but you will need to put an elbow in the port. The recommended port dimensions would be 3" diameter, 15" long for a tuning frequency of 40 Hz. You will have to wire these in series for an 8 ohm load. Our Yung SD200 will be a good choice, without boost.
