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.

Rated 4 out of 5 by from Big sound, Little speakerI have always been keen on the idea of a full range driver system with minimal crossover. I mounted the driver in some 4" sch 40 pvc with silicone and capped the other end to get about 90 cubic inches. Stuffed with a hand full of poly fill the enclosure resonances go away. The resulting curve has two pronounced humps in the upper end of the spectrum. We modeled two notch filters (so much for the simple crossover) and the resulting curve came out + or - 2db from about 120hz to 12000hz. The nice thing is phase shift is almost nill. The sound is very open and completly boxless. I mounted them on some mike stands and all you see when you look at them is the beautiful titanium cone. If there is interest I will post the crossover schematic. Great sounding speakers for the money.

Tang Band W4-1337SD 4" Titanium Driver

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.

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: spazmaster
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...

Could this be mounted in the ceiling?

Just wanted to try this idea I had of mounting one of these to the ceiling of my bathroom as a background music speaker? Since it doesn't technically need a crossover. Am I crazy? Is there a better smaller size that could work too? Mounting would be tricky but I can figure that out.
Asked by: drharper
It would work fine, and likely sound better than any other ceiling-speaker youve heard. Hook it up, run it full range!

Would like to use three of these in a center channel HT speaker-how would they best be wired?

I am building a center channel and these speakers seem to have wonderful reviews as full range speakers which would be perfect when coupled with my towers and sub which have great lower ends. Would they work together in a three speaker array? Would they need a ported enclosure?
Asked by: PhilS
i like two [sum 4 ohm]with a ribbon tweeter[6ohm] crossover at 5 to 6 k in side way MTM look at the efficiency you don't need three and they won't sum correctly ,, either 12 or 2.8 ohms, not amp happy losds

I plan to use this as a center channel speaker. Anyone have any design tips beside the recommended enclosure dimensions?

Asked by: joe64265503
Metal cone are a blessing and a curse. They are far more pistonic than paper and have clean fast transients with low distortion. The problem is when cone break up starts it is severe. You need very fast crossover at least 24 db per octave to implement. This will require an electronic crossover. I am not sold on digital crossovers yet but admit they are getting much better. One other problem with titanium is it rings. Check out the young's modules. The only metal that is stiff and light enough with self damping properties is beryllium. Way too expensive. So for a center channel I recommend a full range with at least 89 db efficiency . A full range will do great on voice. I wish I knew how much power and space you have. Dc gold makes a great full range 4 inch driver that will fit into parts express smallest box. It is reasonable efficient and can be aperiodic damped using microfiber rags. Good luck Ralph
