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 10.
Rated 5 out of 5 by from Outstanding drivers!So I bought 12 of these total for a home theater setup and ended up using 4 to build these round top cabinet desktops. I am aware they are a bit enormous for this purpose but I love great sounding speakers right at my P.C.. I wanted to stray from a traditional yet proven square design and really challenge myself with building these. I do not recommend this unless you have ample amount of time as layering mdf and the time for the body work was waaaay more than I was prepared for. Anyhow, these W4's by TB really sound tremendous considering the size and being a full range. As shown in the photo I used 2 per cabinet and have them all filtered at 80Hz high pass. The box was tuned for a wee bit lower than that but it's not a noticeable difference to my ear as the W8 subwoofer carries the low end home which is also an amazing driver delivering ample bass for this 2.1 setup. I am driving the left and right cabs with the 50w x 2 Sure amps per side found here at PE. I am only pushing about 20watts rms at max volume and they absolutely fill this room which is a 20' x 28' living room. After about a 72 hr break in the tone warms noticeably. Also at peak I have not noticed a lick of distortion. Beware of bad quality MP3's! It will sound awful as these speakers reproduce sound with amazing detail so stick to your cd's or pristine quality media. Also if your looking to blow windows and your ear drums out these drivers will not do so. They deliver high quality sound at desirable listening levels.

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.

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

Currently I'm running 2 of these off a Lepai LP-2020A+ amp. But this has pretty low watts per channel at 8 ohms. These speakers have a 25 Watt RMS. Is it safe to run these on a 35 watt per channel @8 amp? what is optimal/recommendation?

Asked by: oxrod
Yes it is safe to run these with 35 watts. There really isn't an optimal recommendation but more power is usually a good thing. Make sure you keep an eye on speaker excursion at high volume levels.

I'd like to build a pair of cylindrical towers and use 2 of these in each along with a tweeter. The towers will have 6 inch internal dia. Which tweeter and what total volume would work with these please? Should I use a crossover?

At .09 cubic feet and a 1" diameter 4" long port, what kind of displacement am I getting so I can add it to the .09 cubic feet?

Asked by: oxrod
I would recommend building the cabinet to 0.1, after driver and port displacement you will be right at 0.09.

Can I use a Peerless 830878 3-1/2" Passive Radiator with this speaker to get a little more Bass?  If so,  do I continue to use the recommended sealed volume of .04 ft3 or does this require the recommended ported volume?   Will placement matter?

Asked by: oxrod
I would recommend using a standard ported enclosure with this driver for the best results. The Peerless Passive will tune the box too low for an application like this. I would recommend the vented volume that is on our product page, with a 1" diameter, 3" long port for a tuning frequency of 78 Hz.
Answered by: MattP
Date published: 2014-10-09

if I use 2 in a box at .2 cubic ft can I use 2 ports 1 inch diameter and 4 inches long to get 70 hrtz.

Asked by: spunk
In order to get a tuning frequency of 70 Hz in that volume, the port will only need to be 1.5" long.
