Dayton Audio DC28FS-8 1-1/8" Silk Dome Shielded Tweeter is rated 4.6429 out of 5 by 42.
Rated 5 out of 5 by from Still the best.Most of us no longer require shielded drivers but this Tweeter may actually be easier to work with than it's non shielded sibling. I may just be my imagination but it seems to model smoother than the standard Silkie.

Rated 5 out of 5 by from So clear, so smoothDecided to try this in an experimental setup. It sounded so good it made me smile. They say money cant buy you happiness, but this came close.

Rated 5 out of 5 by from Great AdditionWas looking for a n affordable yet long lasting alternative to a old tweeter blown after many years of use. The Dayton fit the bill all the way around. Crisp highs and easy to mount. Hopefully this will last a long time.Great Replacement.

Rated 5 out of 5 by from Great Deal!I bought a pair of these tweeters as replacements to repair older speakers. They work great, a good dollar value. Solid, be careful with the dome not to crush it. Recommended. Quick ship from Parts Express.

Rated 2 out of 5 by from Cheap soundI didn't like the sound at all. They are probable worth 9$ but sound like it too.If you just want sound they fit the bill BUT don't expect great sound.

Rated 5 out of 5 by from Fine example of good bang for the buckA few weeks ago I purchased a Boston Acoustics A-60 at an estate sale. It needed woofer surrounds (which I replaced) and needed the over the hill tweeter replaced. (The woofer is an exemplary performer.)I replaced the tweeter with this Dayton tweeter and also changed the crossover from first order at 3 kHz to first order with the woofer and second order with the tweeter at 2.5 kHz. I installed a five-way binding post in the rear and modified it with the installation of a switch and resistor that allowed for "flat" or slightly rolled-off response. I also clad the BA enclosures with 0.75 inch thick poplar wood, stained, and given six coats of lacquer. The stock grills were fine, although I need to replace the BA badge with one that says HWF, because, other than the woofer, the enclosure interior, and the stuffing, this is my speaker.The sound is sensational, with both pop and classical sources (particular baroque ensembles, which are my favorites), and the RTA measured output from 500 Hz on up (above the boundary-controlled zone) is VERY close to what I measure with my Allison IC-20 main speakers in my music room. The tweeter is exemplary, and I highly recommend it, since it is a fine example of the "best bang for the buck" concept in action.PS: I am a retired audio writer and product evaluator and I know what good speakers should sound like.Howard Ferstler

What's the difference between the shield and not shielded ones? 

Asked by: derekm
The shielded version can be used near a CRT television or monitor without distorting the screen. This does not apply to a flat screen TV or monitor.

Is it ok to surface mounth this tweeter for the project ? Or flush mounting will make much difference ?

Asked by: Kushagra
It is recommended that you flush mount a tweeter. Surface mounting can cause ripples in the frequency response from diffraction issues, but whether this is audible or not is subjective.

Hello, I am looking for a replacement 30 watt 8 ohm tweeter for my Roland DS-90 monitor speaker. Your "Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeter" looks similar although it has only 3 mounting screws and mine has 4. Do you know if there's one with 4?

Asked by: artest7
We have many tweeters with four mounting holes, although there will probably be heavy cabinet cutout modifications to get any of them to fit. If you can call or email our tech support with the dimensions of the cutouts we can see if we have anything that will work. 800-338-0531 x1 or

Is it possible to solder these? And will I break my warranty if I do?

Asked by: Arbenn
Yes you can solder these. The warranty will not be voided if you do but they will not be able to be returned without a restock fee if you do not like them.
