Product Details

Usher 9930-20 1-1/8" Textile Dome Tweeter

The 9930-20 uses a specially coated dome that offers flat frequency response and a very open and detailed sound quality. A tuned rear chamber and a lightweight ferrofluid in the gap provide a well-damped, low resonance point, making for easy crossover design. Top-quality materials including precision cast faceplate, machined motor parts, and an injected back cup are found on these tweeters. This tweeter provides a significant improvement over most $30-$50 tweeters.

Usher 9930-20 1-1/8" Textile Dome Tweeter
Usher 9930-20 1-1/8" Textile Dome Tweeter is rated 3.3333 out of 5 by 3.
Rated 5 out of 5 by from Strong performerI use this tweeter in my 3 way speaker. http://twisterspeakers.blogspot.com/2010/03/3-way-loudspeakers.htmlIt is very strong performer, easily can be crossed over near 1khz. In listening tests 4in mid driver could not compete with this tweeter in 1khz+ range, thus low crossover was chosen.

Rated 1 out of 5 by from Left me disappoinntedI got this tweeter as part of the Dayton Audio/Usher UA701CC speaker. This design is crossed over rather low at 2kHz. I externally broke the tweeters and woofers in using filtered Pink Noise running at about 1 Watt for ten hours.Upon re-installing the drivers and sitting down for an anticpated listening, the sound of the tweeters was disappointing. They sounded especially harsh near the 2 kHz crossover frequency and had a dull top octave (10-20 kHz).I tried adjusting the Treble to compensate the high end dullness but that just boosted the harshness at 2 kHz.So, as a comparison test, I installed a pair of Vifa D27TG-35-06 soft dome tweeters. They sounded much better. Better in the 2 kHz crossover range and in the top octave.So , I ordered a pair from PE and now the speakers really shine. An additional bonus is that the Vifa's cost less then half the price of the Usher's.

Rated 4 out of 5 by from very crisp and clearA great speaker and you can't beat the value. No mounting screws were included but not a big problem.
