Dayton Audio DC28FS-8 1-1/8" Silk Dome Shielded Tweeter
Dayton Audio DC28FS-8 1-1/8" Silk Dome Shielded Tweeter is rated 4.6154 out of 5 by 39.
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

Rated 5 out of 5 by from Dayton silkie W/ sheildingBot these for nearfield computr spkrs. -With $10 JVC 4" papercones as Mid. They exceeded my expectations! What's wonderful is the crossover in the D III build-(look for it)- the result was fantastic: use it just as provided, with the HF tone-down; & a simple inductor for your mid. The phase alignment seems perfect.I did remove the ferrofluid here, but I don't recommmend that- this is nearfield & low volumes only. Subsequent resonance point was 850 Hz, if you should want to build a trap.

Rated 5 out of 5 by from Dayton Audio's DC28FS-8 are truly amazing!!!I bought them for a PA mid/high reinforcement speakers. I was immediately impressed with the crispness, and clarity. They have performed well beyond my expectations. I have since purchased and installed these into 5 other speaker build projects (2 still to be completed). I am a Live Sound Engineer with a competition (winning) car audio background, and have a great ear for sound.

Dayton Audio DC28FS-8 1-1/8" Silk Dome Shielded Tweeter

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 tech@parts-express.com.

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.

Best X-Over point for this tweeter

This will be in a 2-way design and want a pre-built X-over but which one would be prefer d. I will have two 8" 4ohm woofers wired at 8ohms 65watts each 89db for the lower end. Thank You for the help
Asked by: VusstoppyPro
Well, the crossover point could be 1500 hz. to 1600 hz. and slope is dependent on your taste. I have recommended a few below.

Can these be used in an Acoustic Suspension Box?

I have a large acoustic suspension speaker system (sealed box) that I am thinking about tinkering with by replacing the tweeters with these? Would these be OK for this application?
Asked by: ukfan4sure1
You sure can, these will work in any type of box you mount them in. They are sealed in the back so you should not have to worry about any sort of rear wave interaction between this and another driver. Now what you have to worry about is if your original tweeters crossover will work with these. If the original tweeter is 8 ohms then there should not be much to worry about except for differences in sensitivity between these and the old tweeters.

Polarity?

I can't see any polarity markings on the terminals...is the red one (on the left in the picture above) the negative terminal?
Asked by: RDR 75
In everything except thermocouples, red is always the positive lead.
