Rated 3 out of 5 by from Color don't workThis should make a nice 3-way but the gray frame just don't work for me. It would be nice if it was offered in a standard black frame to match. I guess they have their reasons.

Rated 4 out of 5 by from Great in Semi Open Baffle low watt systemAmazing in a semi open baffle system with only 1-2 watt. Details are very rich.In a basreflex system it is a very fine speaker, and ad a big sub and it is really very nice.

Rated 5 out of 5 by from Awesome to my ears.I'll start with performance. Wow. What all the reviews say. Impressive, very clear & an audible bump at around 12k right in the sibilance range (cone breakup). If you're building with a tweeter, your network will cross before that so no issue. Looking forward to it sounding even better after break-in. Read on if you like to see what I did with it as a full range.My first build & very pleased with the results. A powered mono mix cube (Auratone clone). 6" cube with 3/4" plywood. Made a plate amp with:- Kemo M034 mono amp (check review)- Dayton Audio SBPP-BK plate (check review)- Neutrik stereo jack & 10k switched pot- 4 amp fuse assembly & power jack- 4 amp power supply (check amp review)- A 20K ohm + two 470 ohm resistors to sum signal to mono.- Air coil inductor to roll off HF & tame sibilance.The Jantzen .2mh inductor took some experimenting removing a lot of copper from the coil in stages until it sounded right. Sorry I can't tell you what mh value I ended up with. Dimensions inside the cabinet were perfect so I don't recommend going any smaller. I put a piece of rock wool for damping between the amp & the shielded speaker base leaving plenty of air around the cone inside.All said and done the sound quality far exceeded all my expectations, it's like the musicians are right here with me, moreover it was fun and I saved a lot. Anyone who says this driver is expensive doesn't know how good it really is. Well worth it in my humble opinion. Thanks for reading.

Rated 4 out of 5 by from More than a full-rangerCan't call this driver excellent in all categories but build quality is worth more than the price tag and versatility can't be questioned. On first testing I'd say that with a parallel filter around breakup this driver would make an excellent combo with a high end woofer or 2.1 with sub. Toe-in controls the top end well enough. VERY low harmonic distortion for the price! Tested against drivers of 4x the price yields equal results just breakup closer to vocal range and more rise in resistance at the top. FR does NOT extend to 20khz! ...but, did you really expect that? Out-performs many fostex drivers imo. Especially in the high mid/presence range though a little elevated there. Buy it, control it, add low end to it and it'll be a good friend i think!

Rated 5 out of 5 by from On 2nd ThoughtFurther down the reviews I posted my first impression, which was wow. Since that time I have switched these over from an SET amp to a rebuilt Scott 340-B tube receiver. So they go a lot louder now. Still using the filter from the project. Once again, wow. It is just really hard to get used to idea that these little drivers generate such musical presence and detail, but there you have it. Of course it doesn't hurt to have the Scott pushing them, but still, these drivers are for real.

Rated 4 out of 5 by from Very pleasedI used two of these with a 2.1 Channel Dayton plate amp along with a 10" sub in a portable system. These drivers perform very well in this application, clear and loud. Although only being driven @ 25 wpc, they will hit very resonable sound levels.

Tang Band W4-1337SD 4" Titanium Driver

My W4 1337 speakers got damaged. How can I get replacement cones for them ?

Asked by: Humberto
Unfortunately replacement parts are not available for these, all you can do is purchase new speakers.

Other than the magnet material, what is the difference between this driver and the W4-1337SDF?  If magnet is the only difference, why does that justify a 50% higher price (i.e. what's the performance benefit)

Asked by: mprisbrey
The magnet is the biggest difference. The reason for the price hike on the neo version is simply because of the cost of the neodymium material itself. This is the main reason Tang Band developed similar models with ferrite magnets to help lower cost. Performance for both will be virtually identical.

Is this the speaker used in the Statement Monitor, or is it the W4-1337SDF?

Asked by: Matt_Getz
The model used in the Statements is W4-1337SA which is no longer available. I would recommend asking the designer if this is a suitable replacement for it.

I hope to use these in an orion styled dipole speaker. Is it okay in an open baffle from 400 to 8000 hertz? These will be actively filtered, 24db/ octave.

Asked by: Slapshot
Yes this will work fine in that application with those crossover frequencies.
Answered by: MattP

I see one review that indicated the cone is a painted poly cone.  Is this in fact a titanium metal cone or a titanium colored cone?

Asked by: mark47803
These cones are made from titanium.

can this speaker be used in a car application?

Sorry to ask if this is a dumb question. The Pioneer deck in the car states it will work with 4 and 8 ohm speakers. I realize these are 8ohm speakers. But would they perform well? Most reviews are for home applications. Just want to make sure. Thanks for reading.Humble audio newbie...
Asked by: mparkis
It will work fine, as far as the impedance. Don't expect a lot of bass, however, as the xmax is only 3mm. For that money, I'd look into a more rugged coaxial...
