Rated 5 out of 5 by from This speaker has a Napoleon complexPurchased over one year ago to replace the driver in a entry level Kenwood SW-38HT.This sub came in a home theater in a box deal.Removwd OEM driver filled cabinet with accoustastuff ,installed Tang Band W6-1139SIF and was BLOWN AWAY.I was resigned to buying a "real"sub but this driver swap made that unecessary.The best part is that it is very clean and you can hear different pitches of base,this is not a one note driver.Very reccomended as a upgrade for small powered subs

Rated 5 out of 5 by from Excellent as in-door subs!I replaced the rear 6.75" factory speakers in my 2013 Nissan Frontier with these guys. Nobody sits back there anyway, and I wanted some low-end for my commute.These are running infinite baffle (free air), driven by an Alpine MRX-F35 getting about 60w apiece. After a break-in period of a few hours, they are really coming alive! People don't believe me when I tell them it's a pair of 6.5" subs and less than 150 watts between them.They are more musical than I expected them to be in an IB setup. They keep up with the 6.5" components up front at any volume that one should reasonably be listening to. Are they like having a 10" or 12" in an enclosure? No, of course not. But they're darn close and completely hidden, out of the way, and novel. They make me grin.Would I do this again? Absolutely, 100%.

Rated 5 out of 5 by from Surprising sound from small package!I had thought I might be disappointed at first, but when the bass comes in it comes full and deep. For once in my life I had to turn the sub amp down. The amount of bass frequencies being emitted from these little air movers actually hurt my ears.I re-purposed an old Kirkensataer studio monitor cab, turning it into a quick tapped horn box. spent 40$ on various materials and hardware. Using an Old Phoenix Gold MPS - 2240 car audio amp bridged with the two Tang Band subs wired into a 2 Ohm configuration. Its good. Car is '79 Volvo 245 DL Box fits perfectly and its hidden from sight and I retain all of my cargo space.

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).

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

What is the diameter of the roll surround? I need to create a baffle for a push pull isobaric clam shell configuation. I want to make sure the roll does not rub the side walls of the baffle.

Asked by: bigkan
The outer diameter of the rolled part of the surround is 5-3/4".
Answered by: MattP

how do you wire 4 of these to a 4 ohm load with 2 groups of 2 speakers in an isobaric configuration.   My mono amp has 2 channels that internally makes it parallel.  Or I can just use one channel.

how to wire four of these in an isobaric Configuration and get a 2 ohm load?

Asked by: bigkan
You can't. Four of these can only be wired to 1 ohm, 4 ohms or 16 ohms.

Can l use 4 of these in a 12"x12"x12" ported enclosure.   I would like to use an external round port.  Do you have any suggestions for port diameter, length and how far to insert it into the box?

Asked by: bigkan
That volume is pretty small for four of these but an external port will help. I would recommend a 4" diameter, 15" long port for a tuning frequency of 40 Hz. The length of port inside the box won't really make a difference as long as the whole port is 15" long.

I am interested in installing this in the .494 ft^3 internal volume prefinished Dayton Audio cabinet (Model: TW-0.50BK), with the Dayton 25W plate amplifier (Model: SA25). Does this sound reasonable? What size port do you reccomend? 

Asked by: Wagud
The volume will work well, and with only 25 watts you can get away with a port that is 1.5" in diameter and 6" long for a tuning frequency of 33 Hz.

In have a ported enclosure built for 3 6.5" sub's for a truck . 1.4ft3 down firing and 2 side ports tuned to 34. I planned to use the 1139sif but I'm i on the fence about using the neodymium version . Is there going to be any exceptional benefits w/ neo @

Asked by: cudafish
The only benefit to using the neo version is to safe on weight, performance will be no difference.
