Product Details

Tang Band W1-1931S 1" Neodymium Full Range Driver

Tang Band's W1-1931S micro full-range driver features amazing performance that belies its diminutive 31 mm diameter (under 1-1/4") size. The patented design employs a unique polypropylene cone, with flower petal embossments, that's mated to a neodymium motor for maximum BL product in the voice coil gap. A free air resonance of 170 Hz allows you to pair these nearly any woofer or subwoofer up to 6-1/2 feet away without localization and beaming effects (poor off-axis response).

Additionally, you can use these drivers in multiples for an awesome line-array speaker that requires a miniscule footprint. Great for use in designing micro LCR (left, center, right) speakers for modern flat panel HDTVs, or even computer desk and laptop speakers. The high-fidelity nature of these drivers is exemplified by their low Qts specification (quite rare in drivers this size), while the ultra-low inductance allows these to play relatively flat frequency response up 20,000 Hz! Ferrofluid cooling protects and cools the voice coil, while the mineral-filled polypropylene cone combines with the Santoprene surround for use in harsh environments. Press-fit frame design minimizes center-to-center distance.

Note: Higher power handling can be achieved by using a 200 Hz 2nd-order high-pass filter, or by using multiple drivers together.

Tang Band W1-1931S 1" Neodymium Full Range Driver
Tang Band W1-1931S 1" Neodymium Full Range Driver is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Works for me.Im running an active three way stereo in my F150 using a Pioneer DEH 80PRS as the source unit. The Pioneers tweeter channel has an adjustable crossover that can go as low as 1.2k, so I used this broadband driver as a tweeter crossed over at 1.2k with a 24 db slope. My tweeters are mounted on my dash and the broader range of this driver has allowed me to get a better image. These are rated to 20k but I feel that is not the case. The highs are not as crisp and airy as metal dome tweeters, but in my application, this is an acceptable trade off. I do wish that these came with some kind of mounting cup for flush mounting. Right now Im using velcro.
