Tang Band W4-1320SJ 4" Bamboo Cone Driver
Tang Band W4-1320SJ 4" Bamboo Cone Driver is rated 4.5 out of 5 by 10.
Rated 5 out of 5 by from Kind of SurprisedI built a mildly tweaked TABAQ for a pair of these drivers for fun. My expectations were pretty minimal, I was expecting a lot of shout, no treble, and no bass, but these little drivers work really nicely.I have found that positioning is pretty critical, as there can be some pronounced peaks if you aren't careful. I'm not too bothered by the small ~7kHz peak that I ended up with, it's sharp enough that I think I'll leave it alone.I've uploaded an Omnimic frequency response chart at 12" with no smoothing. The contribution of the port is not shown in this chart.

Rated 5 out of 5 by from Excellent Cone Driver For Vocal RenditionI have been wanting to try this driver for a long time & it finally went on sale. I bought two of thes to use in a Tri amp set I created. I wanted these drivers because the spec sheet indicated pretty flat responce, among other things. I put these in place of my two KEF B10's and was very surprized to hear them sound every bit as good as the B110's!!The vocal rendition from these is excellent with no peakiness or strain- in fact wuite smooth and articulate. These are very good cone drivers and compete well with the HEF B110's. They take 300 hz and 4khz xover points very well at 12db/oct.I have other plans for these driver to see how well the integrate with 15" & a 12 woofers and ribbon tweeters. What I have heard already inpresses me a lot!

Rated 4 out of 5 by from Great little clearance buyThese fullranges in the W4-13xx series are just amazing. I've used the 1337 titanium previously; this clearance deal led me to take a leap and see how the paper/bamboo cones perform in the same platform.Measured nearly ruler flat to 10k, only a few -3dB dips here and there. They sound excellent just running as full range while auditioning.I believe they'll make an excellent mid in a new high sensitivity WWMTMWW I'm planning.

Rated 5 out of 5 by from Small WonderI have used several pairs of this driver over the years, coming back to it for its good nature and musical performance. This bamboo cone is far more natural sounding than many metal or plastic cone drivers and it takes a lot of power before getting stressed. I use them only in transmission lines but their performance is excellent in this capacity. This driver's character does not change with increased power input...it maintains a stable "personality"unless clearly over-driven. At the $30 sale price this little guy simply rocks and is one great bargain. It is also superb as a dedicated midrange in 3-way systems as its low end capability allows for a very low crossover point.I wish Tang Band made a 6" version of this driver....

Rated 4 out of 5 by from Not the best for fullrange, but a terrific mid !I had started off with the W3-1364SA bamboo driver which is the smaller version of these. I think they are one of the best mids Ive ever heard, and they are being used for semi-full range duties as they are paired with an 8" bass driver.These W4 bamboo coned mids are very clear and airy. I prefer the softer and more natural sound of a paper cone, but I can also appreciate the accuracy and lower distortion of a metal cone. These bamboo cones fall somewhere in the sweet spot between the two. They have good sensitivity, good xmax and low (enough) distortion. The truncated frame makes for easier installations. Nice machined aluminum phase plug and neo motor provide function and beautiful form. Unfortunately, the off axis response is not suitable for full range use. But combined with a good tweeter, this driver can be the star of a fantastic system. I gave a 4 for value as they are a little pricey at just under $50. Fortunately for most Tang Band products, you get a quality engineered and built product for your duckets. Tang Band, Peerless, Vifa, Dayton...all are putting out incredible performance to dolalr value products that compete with(and in some cases best) the higher end competition. I highly recommend picking up a pair of these drivers (or the 3" version)and giving them a try.

Tang Band W4-1320SJ 4" Bamboo Cone Driver

what's different between sj and sjf ?

between 1320 sj and sj f (full range) is it only cooper ring inside(down distorsion) or more ?
Asked by: halan
In this particular case, the SJ is the original neodymium model, SJF indicates a ferrite magnet. Aside from that difference, the speakers are very similar in specification and performance.

Will this work with the dayton passive crossover?

I want to use the dayton passive crossover with this as a mid.with the impedance changes of it per the plot on the specs sheet, will the crossover still perform properly??also which xover point will be better, 3.5k or 4.5k?
Asked by: calvinr
Yes, the Dayton Audio passive crossover(s) will be fine with this driver. The "better" crossover frequency will be based on the tweeter you use in conjunction with this speaker. This speaker itself will be fine crossed at either 3.5kHz or 4.5kHz.

Are a pair of these enough for stereo in med-size room?

I have a room that measures about 20 x 16 with 10 foot ceilings. Is 2 enough for acoustic and light rock music listening, or can these be wired to have 2 per enclosure for stereo?
Asked by: Sonidos
These are not large enough this room. You can go with a larger MTM pair (2 5"-7" woofers with a good dome tweeter (silk), and a 10" powered subwoofer. That is ideal. If you use two of them in a box, they won't give you the sound level that is required for that size room. They are just not big enough. Check the speaker buyout section at PE, and for the price of one of these speakers, you get two good Peerless India 6.5" woofers (8 ohm for MTM on a PE two way crossover), and a good dome tweeter (Vifa soft dome). For the price of two of the TB speakers in a box, it covers the two way crossover costs, with $40 left over. maybe to upgrade to 6.5" Peerless SDS Woofers (still need a sub with a room that size, at this price level). If you try to save small amounts of money when you are building speakers, you will end up buying better parts not soon after you are done. So, it is best to spend the money the first time. Speakers can cast a funny spell on you, once you get into the game, and money starts flying away. I am currently reconditioning a set of ADS top of the line in 1986 4 foot tall towers, and mids and tweeters are first rate (Braun) The dual 7" wooders don't have large magnets, but after all of these years, the paper cones have held up, and now with black wet look, they will be stronger and tighter sounding. I am dissappointed in the level of the cabinet quality (have to use a 3/4" plywood reinforcement behind the woofers, as the front baffle is too cheap (OSB, not MDF) and thin to make for a solid baffle), but the design is okay. The point is that after still having set of Speakerlab 9's and a passive 10 subwooker since 1982, when you take them apart, look around for a better woofer and crossover for the 9's, you learn a few things about spending that extra amount that you might hesitating on. With buyout speakers, you can have it both ways, inexpensive and good quality.
