Product Details

Tang Band W1-1942S 1" Full-Range Neodymium Driver

Tang Band's W1-1942S micro full-range driver features amazing performance that belies its diminutive 46 mm diameter (just over 1-3/4") 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 120 Hz allows you to pair these nearly any woofer or subwoofer up to 9 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 150 Hz 2nd-order high-pass filter, or by using multiple drivers together.

I just listened to these in a temporary box. These are going to be used for a campsite table top. I was thinking some BSC.might work to even the sound out. Amazing how good these sound. The baffle hieght is 3" and the width is 10 inches

Asked by: magila77
We do not have a way to accurately model a BSC filter. I would recommend hopping on our Tech Talk forum as asking there, there are many guys that should be able to help you out.

is there anyway to enhance the bass on these, say a bass boost circuit?

Asked by: magila77
Other than adding specific EQ, these are not designed to reproduce copious amounts of low end, especially if you want any real output from them.

Attempting to raise soundstage in a Honda Fit using stock tweeter locations. With a high crossover would this be a good choice?

Asked by: Fitest
This little guy has a response down to 120Hz, so try the existing tweeter crossover/hi-pass in the car first. You may even be happy w/o a filter at all--the stock tweeter is likely crossed over at 3-5KHz--a bit too high for what this will deliver. Good things come in small packages--here is one of them. Speaker tech has come a long way!

How big an enclosure is required

Asked by: fwbutler
I would recommend 0.0156 cubic feet with a 0.3" diameter, 1" long port. This will tune the enclosure to 98 Hz.

Have a motorcycle helmet with built-in Bluetooth. Would these work to upgrade the wimpy little speakers it comes stock with?

Asked by: Papashanga
This depends on the amplifier driving the helmet elements. If it's not stable to this low impedance, then I would not recommend it. Most headphone and helmet diaphragms are a set of units made to meet the goals of close-proximity to heads.
