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 4.4688 out of 5 by 64.
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.

Rated 4 out of 5 by from Great little woofer but the published Vas is off by a cubic foot!!After purchasing this driver based on its very low advertised Vas, I was very surprised to find that it measured 1.31 cu ft making it unusable for my application.

Rated 5 out of 5 by from W6-1139-siUsed the W6-1139SI in a transmission line box tuned to 38Hz IIRC. This was One year ago. excellent frequency response range and power.As far as value for the dollar... It was great then, $45 on sale, it was $60 regularly. Now it is $100??!? What gives? Wait for a sale , if it ever comes. If you want it now, you won't be disappointed (if you are realistic).

Two of these in a car, vented

I've perused the various comments and I know I'll have enough room behind the seats in my 1996 Miata but I'd like to get more exact build plans. Since this is a car and will play music only, no HT, what would be the optimal enclosure for two of these drivers? Both in one enclosure or separated with separate vents? F3 doesn't have to be as low as HT, actively LP crossed ~80Hz.
Asked by: chris45
When it comes to vented enclosures there isn't really an "optimum" configuration because there are so many performance measures that need to be balanced and compromised. But, I've listed a few good designs below, some of which I've built. All of them use both drivers in the same box. Separate boxes could be used for each driver, but that would make no sonic difference at all. For most of them I used rectangular ports because:1. These are easy to make using the wood that you use to build the cabinet2. Most of these enclosures require long ports, which aren't readily available with standard round ports. Shorter, narrower ports *could* be used, but that would produce HUGE amounts of port noise at moderate to high volumes. In all of my designs below, there will be no appreciable port noise with power levels up to 50W.3. The selection of diameters of round ports is fairly limited, esp with plumbing pipe, which is one of the better sources of long round ports- 0.5 cu ft, 2 ports that are 1.8"x1.5" (rectangular) and 10" long. 3-dB at 49Hz- 0.8 cu ft, 2 ports that are 2"x1.8" and 9" long. -3dB at 43Hz- 0.8 cu ft, 2 ports that are 2" inside diameter (round) and 7.5" long. -3dB at 43Hz- 1.2 cu ft, 2 ports that are 2"x2" and 8.5" long. -3dB at 37Hz- 1.6 cu ft, 2 ports that are 2"x2.2" and 9" long. -3dB at 33HzAlso note: Some people might suggest some designs that use shorter ports than what I listed here, but beware of those designs. With this TangBand driver you can't really make a good vented box with a short port. Doing so will either create tons of port noise, create huge spikes in the frequency response, or have an incredibly high -3dB frequency.

What size screws do I use to mount the subwoofer?

Asked by: azman
The screwholes are 4.6 mm, so #8 screws are recommended. See the linked product below.

Can Parts Express offer me assistance for building an enclosure for this speaker?

Asked by: Little John
The optimum enclosure for this speaker is 0.88 cubic feet (13" cube using 3/4" material) that uses the 2" Precision Port kit (listed below) cut to 11" long. This will tune the enclosure to 30 Hz.I have also listed a subwoofer plate amplifier that will work nicely with this.

Will these work in sealed enclosures?

If so, what is the recommended interior volume?
Asked by: TheDog
Yes, it will work fine in a sealed box. However, a sealed box will have much less bass extension than a ported box. The optimal volume for a sealed box is approximately 0.2 cu ft, although anything in the rage of 0.15 cu ft to 0.3 cu ft will work pretty much just as well. The 0.2 cu ft box will have bass extension down to 70Hz; the small boxes will have slightly less bass extension, and the larger boxes will have slightly more (only a few Hz).Note that a properly-designed ported box with this sub can have a frequency response down to approximately 30 - 40Hz (depending on the design), so porting it will give significantly more bass. One of the other Q&A's for this product mentions a ported design that could work, although my simulations show that that design will have a lot of port noise and an uneven frequency response. If you look online you should be able to find many good ported designs for this sub, since it is quite a popular sub.

How well do this woofer perform in infinite baffle setup?

planning to use this as subwoofer on the rear deck of my civic, head unit powered. Lastly which of the two passives will work for my application? 80hz or 100 hz low pass crossover?
Asked by: mark 888
This woofer will work OK as an IB sub but you will want to power it with a little more power than a head unit can provide, I would recommend a solid 50 watts per channel. Either low pass filter will work, if you use an amplifier it will probably have an active filter built in which would be variable.

Why did these subs double in price?

Asked by: aerodynamics
The price of raw materials for the neodynium (spelling?) magnets has risen sharply recently, and the expense is seen in rising prices.
