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 9.
Rated 5 out of 5 by from I'm a little surprisedI bought a pair of these speakers to serve as mid-range drivers in a three-way speaker system. The testing I've done indicates it will serve well in that application and has the kind of broad bandwidth I needed to use the kind of special x-over that I wanted (Bessel filters) What was a bit surprising was the precision of assembly evident by close observation. This must be the product of some kind of sophisticated automated assembly process as I believe the minimal adhesive used and the precision of it's placement is probably beyond human hands. Impressive. Every part looks like a little jewel in a setting. They are also serialized. My pair are #393 and #396. That was very surprising for such a reasonably priced speaker.The only caution I would like to voice is that these are pretty low sensitivity speakers and despite the spec-sheet's claim of being a "high power loading design" this has to be taken with a grain of salt. It's rated at 25 watts rms so you won't be rocking the house with a pair of these. That shouldn't be taken as a damning comment, I think they are really special little speakers, just have realistic expectations, that's all.

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.

Tang Band W4-1337SDF 4" Titanium Full Range Speaker

Hi What would be the ideal volume for 2 speakers? (I suspect its not just a case of doubling the volume for 1).  Also what length and diameter should the vent be? Finally as I am using these for a centre speaker, can I place the vent between the speakers?

Asked by: Pretender
Actually it is as simple as doubling the volume for two. I would build the enclosure to 0.2 cubic feet so you end up with 0.18 and use a single 1-1/2" diameter, 3" long port for a tuning frequency of 75 Hz. There is no problem putting the ports between the drivers on the front of the cabinet.

Which option is better for the volume of 0.21 cubic feet, sealed or vented? If vented, what size of port?

Asked by: ksv200861
The Vas is not the recommended box volume for the driver. The recommended enclosure for this woofer is 0.125 cubic feet with a 1.5" diameter, 6" long port that will tune it to about 75 Hz.

I would like to use 4 of these drivers in a single enclosure. what is the enclosure and port size to achieve the best bass?

Asked by: chris 13
.36 cubic feet vented volume of cabinet. The vent will be a bit smaller than one speaker's cone size. Try a smaller vent first and see if you like the bass response. You will get coupling using 4 of these in series/parallel wiring for more than the stated low end response. Too large a vent will "unload" the bottom response--and sound muddy.

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.

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.
