Product Details

Tang Band W4-1320SJF 4" Bamboo Full Range Speaker

Tang Band's W4-1320SJF 4" speaker features a bamboo fiber paper cone with half-roll rubber surround. This optimally damped cone material is rigid, lightweight, and durable. The driver's 18 oz. ceramic ferrite magnet and underhung 1" voice coil do their part to ensure very low 2nd and 3rd order distortion. A machined aluminum phase plug improves high frequency performance, and a strong cast aluminum chassis maintains proper component alignment. The W4-1320SJF's truncated frame edges permit close driver-to-driver spacing and reduced baffle frontal area. Also available in an easily recessed round frame version, the W4-1320SIF.

Tang Band W4-1320SJF 4" Bamboo Full Range Speaker
Tang Band W4-1320SJF 4" Bamboo Full Range Speaker is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Does very well with a ~.27 cu ft box (needs a little EQ)I ordered these with very high expectations, and played them at moderate levels outside of a box for about 3 days straight to break in.Well I did the recommended 10 X 8 X 6 inch box (3/4 MDF might have made this a little heavier than required), and although physically my woodworking isn't pleasant, the whole system sounds great. I threw in acoustic foam on all the walls and put in a port tuned to about 55 hz. This really does play all the way into the mid 50s.Where it REALLY shines is the mid-bass to maybe 10k. Man, I spent a couple hours going through my library of Norah Jones, Alexi Murdoch, even Richard cheese. I then played some Yes, Dave Matthews Band, and Pearl Jam. The stuff that really shine are vocals and acoustic instruments. Even with only one speaker hooked up, the instruments have an airy feel to them. The speaker is very quick, but a little flat on the very top end. Electric guitar sounds really good too, but it doesn't have as much bite as it could through, say a dedicated midrange speaker in a 3 way.I know it's a 4 inch driver, that's why I still give it a 5, but it does lack a little treble. I think I will throw a grill on these and make them garage speakers, until I can improve my craftsmanship and make a pair that meets the WAF. I was thinking of making a pair of surrounds and a center with the 3 inch full rangers on closeout, and hook up my old Sony SACD player to my Onkyo for a very enjoyable time in the garage building speakers.

Rated 4 out of 5 by from Nice speakerThis full range speaker has fairly impressive bass for a speaker of this size. Installed in a 300 cu.in. ported enclosure which is about the smallest enclosure I calculated for any of the 4" speakers. The highs are fine but not quite as good as a dedicated tweeter, but the beauty of a full range speaker is that there's no need to buy and design a crossover. Made four of these for a surround system. One thing to note is the exposed voice coil gap, so keep these things in a clean environment when constructing and keep the grilles on the enclosures.

F3 of this driver? Enclosure?

Does anyone have the F3 of this? I was looking to making a mid sized pair of bookshelf speakers for my desk at the office, so it won't need to be loud. I would like to have usable bass extension down to at LEAST the FS, but maybe a little lower if porting can do so efficiently. Just bought a pair and can't wait to experiment!
Asked by: RossC
The recommended enclosure for this driver is .13 cubic feet with a 1" diameter, 4" long port. This provides a tuning frequency of 64 Hz and an in room response into the mid-upper 50's.

Is this Tang the same as the one with (almost) same model number, W4-1320SJ?

I'm considering buying one of these, but can't see from the specs how they are different, except that the version with F in model number as what looks like a 'shield', right? But that situation is usually denoted with an 'S' in the part number, not an 'F', right? So what is the meaning of the 'F'?
Asked by: denizen2
They will perform very similarly. The primary difference is that this one has a ferrite magnet motor, and W4-1320SJ has a neodymium magnet motor. The "F" in this case denotes ferrite. There is also a round framed ferrite version, if you are interested in that.Neodymium magnets are much smaller, and have much less magnetic stray. That is, their magnetic fields are more focused around the voice coil, so they need less magnet mass to have the same effect. This also provides a bit of faux-shielding, if you will, so they neo version can be placed in closer proximity to a television without a problem.
