Tang Band W4-1337SDF 4" Titanium Full Range Speaker
Tang Band W4-1337SDF 4" Titanium Full Range Speaker is rated 4.9286 out of 5 by 14.
Rated 5 out of 5 by from A true full range driverI bought a pair of the TB W4-1337SDF full range to use in a 2.1 setup as the left and right full range with a subwoofer. I found the W4-1337 is a true full range with supper low to midrange and defined high above 2kHZ. No need for a twitter. I drive these with a 11watt stereo tube amplifier tapping the sub signal off the tube amp volume control. The 2.1 setup works great in the 11'x13' room installation. Definitely very satisfied and impressed with this TB product.

Rated 5 out of 5 by from CLEANI bought 2 of these speakers for a DIY project. After reading some reviews, I figured that these were a good bet, but I had no prior experience with Tang Band speakers. All I can say after hearing them, they are SUPER CLEAN in the mid to high ranges, and the bass hits HARD for a full-range speaker. I also love the look of the Titanium cones, which added a lot of aesthetic value to my project. Since my first project a few months ago, I've bought 4 more of these for new projects. WORD OF CAUTION: Be careful when you install these speakers. The Titanium cones are tough, but they dent really easily, which I found out the hard way on my first project. The finished product looks way better without any dents in the cones!!!

Rated 5 out of 5 by from the 4 in full range with some punchI've been eye balling these for awhile and decided to just go for it.I was simply amazed of the quality of the product they are heavy for a 4 inch speaker (there actually 5 inches from one side to the other).the sound quality is amazing highs mids and some bass as well not too much just enuff pretty much a all around full range speaker.Well worth the 48.00 I plan on buying more for home theater speakers.this is a work radio I need it loud due to machines running and and we have to wear ear running a SURE amp 100 x 2 it's on the inside yes it's a sealed box there are NO heat using a 24v 14.5 amp power supply which is not shown in the picture.

Rated 4 out of 5 by from Good DriverI hate to be the person that gives it 4 stars but for me giving a speaker 5 stars means that it's a fantastic all-around driver when it's in the class Of a full range. I was completely shocked to hear the bass frequency for a 4 inch speaker in a multiple array. It had significant amount of bass considering its size. My only issue is the higher frequency range, though it does hit the notes above 10k, it seems as though the SPL drops way under 89.I cannot complain for I built this for a center channel and it's going to sound fantastic

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.

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

G'day Guys, Just purchased two of these drivers and would like to put them into a couple of vented enclosures. Which is the recommended tuning frequency of the port 70hz or 78hz - 1" by 4" or 1" by 3"?

Asked by: Daza
A lower tune will have a smoother bottom response, a higher tune will have a slightly steeper roll off. You can always experiment with both and see which you like the most, but I highly doubt you will hear a difference between either option.

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.
