Tang Band W4-1337SDF 4" Titanium Full Range Speaker
Tang Band W4-1337SDF 4" Titanium Full Range Speaker is rated 5.0 out of 5 by 8.
Rated 5 out of 5 by from quality for the right priceI've bought 4 of these for a bluetooth boombox. So far I've used 2 in the box and my mother in-law can't stop listening to it. I'm very please of the sound quality. I use it in conjunction with a tweeter I did not use this as a full range. Can't go wrong top quality for the right price.

Rated 5 out of 5 by from As Good As It Gets!Most people think you have to spend 1000's of dollars to get good quality parts.... No ... you have to be able to interpret specs and use a little bit of educated intuition. These are paired with some Hi-Vi M6N's and sound better than speakers costing thousand's of dollars. Of Course the speaker enclosures defy conventional design wisdom as they are my own proprietary design. Being an engineering tech.......I think a little differently than most people. These sound much bigger than they are......... in inordinate amount of bass with pristine mids and sparkling highs ......... no sub needed.

Rated 5 out of 5 by from AmazingJust unpacked and tested. The looks and the construction are simply amazing. The first tests were superlative. I can hardly wait to build a cabinet for them.

Rated 5 out of 5 by from Dreamy even as mid/tweetsI used these as midrange/tweeters in a 2-way with Dayton reference series 8" woofers. With a 2nd order crossover point of 500Hz, a zobel network (necessary), and some attenuation (also necessary in this design) these sound absolutely stunning, even at high frequencies.They are more directional than tweeters with a smaller diaphragm would be (large diaphragm = destructive interference off-axis from sound produced by different sides of cone) and they definitely need the zobel network and a decent break-in period to sound good on the high end, but the wait is worth it. I can't believe how well these perform in this role. I haven't tested them properly yet (despite access to several million in audio equipment here at Stanford) but running frequency sweeps reveals no significant dips or humps in their response...I've been lugging 100lbs of speaker up and down several flights of stairs just so I can listen to these in a proper space (/not a dorm room).Seriously. Buy these; they are amazing.

Rated 5 out of 5 by from W4-1337SDF with Vifa D19TD-05 = OMG ! The best 2-way !!!Hello guys !!!I am so excited , i just finished building a pair of small shelf speakers with the W4-1337SDF and vifa D19TD-05 and i have to say .... OMG just OMG !!! No words !!! The best sound quality i have ever heard from shuch small speakers, sound is so rich and soft with precise highs and breathtaking mids and lows. The crossover is a bit complicated for the W4 with 3rd order and notch filter but for D19TD just simple 2nd order 5khz high pass. I did not painted them yet just can't stop listening to my favored music.I had before them 2 modifyed microlab shelfs with 6" woofer and 1" Morel tweeter , guys... not even close !!!! W4 blow them away even in lows !!! The speakers driven by DIY TDA7263 stereo amp which i also buit.No way spending on B&W 500$ or some other high end brand. These W4 and D19TD really kick butt :) Highly recommended !And don't go for the W4-1337SD they are much more expensive and deliver the same results. Moreover the heavier SDF make your speakers feel more serious.

Rated 5 out of 5 by from Great Little SpeakerSuper little 4 " speaker, very clear audio over the full range, plan to use them as mid range speakers for a more full sound.

This vs. the W4-1337SD

I am relatively new to speaker building and would like to use one of these two with a sub in a 2-way design. Could someone please do a more detailed analysis of the specs and SPL/Frequency plot that would help me decide between them? I was impressed by the SD's reviews, and I would like to go with the SDF because of the lower price but am not sure if it would be as good a choice. The high end of the plot looks rougher, for example. Would that make it harder to get the SDF to perform as well as the SD at high frequencies? What about other features?
Asked by: WSmith
Just wanted to correct some information provided in the previous answers and try to actually answer your question...The statement that a driver with "A qts of .4 or less is best in a sealed enclosure, while .4 or greater in a vented design" is completely backwards. To quote Vance Dickason #Loud Speaker Design Cookbook, fifth edition, page 16#, "Closed-box loudspeakers generally require woofers with a fairly high Qts of greater than .3", and also #page 43#, "Woofers for vented enclosures tend to have less cone mass,... and lower overall Qts".I wanted to quote an expert so you didn't have to take my word for it, but this is a pretty basic rule of thumb. Also, a difference in Qts of .03 #.34 to .37# is not significant if you are planning to use these with a sub where you wouldn't be worried about bass extension. And it's probably well within the measurement uncertainty of the equipment used to determine Qts, anyway.I would go with the SDF due to it's higher efficiency and lower cost, but that would just be my preference. A small vented enclosure should give you an F3 of about 90 Hz, which would work well with a sub. And the high frequency response shouldn't be an issue if you are using it in a two-way design, as you state above.

One reviewer added a complex notch filter and employed a tweeter. You would think a little 4 in full range driver wouldn't need all that.

I would think the reason for a full range driver is to keep things simple. I was thinking of this driver for a simple 2 way, the reviews seem to imply it needs doctoring, would this driver beokay stand alone or is the doctoring nescessary.
Asked by: sammy malone
I'm using these for >500Hz in a two-way and have them in their own small, completely lined division of the larger enclosure. All they seem to need is a zobel network to tame the very top end. With that and time to break in they sound incredible (and I'm assuming they would be even less likely to need filtering below 500Hz).

Sealed or Vented

Is this driver better suited for a sealed enclosure or a vented enclosure?
Asked by: Zerkfitting
These will work in either type but if you want useful bass from it I would recommend venting.

What is the difference from the W4-1337SD?

Asked by: Mike B.
The "F" at the end of this product's model number indicates a ferrite magnet structure, as opposed to the neodymium magnet of the original model. We can most likely expect this general trend to continue, given the exponential increases in the cost of neodymium over the past year or so.

Enclosure recommendations.

I'm interested in purchasing these for a project and have a few questions. First, will these perform well when run full-range, with no filters, crossovers, etc? Second, what size and configuration (ported or non) enclosure would be optimal?
Asked by: dstudinski
Whether this driver will need any type of filter is subjective, it will probably be fine by itself for most applications. The recommended enclosure size is 0.09 cubic feet with a 1" diameter, 4" long port for a tuning frequency of 70 Hz.

Enclosure recommendation follow up

An enclosuure of .09 is recommended; is that volume factoring in the space taken up by the port itself and the magnet? In other words, would I have to add the volume of the magnet and the port to the recommended enclosure volume of .09 to arrive at the correct overall enclosure volume?
Asked by: dstudinski
The 0.09 figure is total box volume. If you build it to 0.09 you will end up with about 0.075 after displacement.
