Dayton Audio DC28FT-8 1-1/8" Silk Dome Truncated Tweeter
Dayton Audio DC28FT-8 1-1/8" Silk Dome Truncated Tweeter is rated 4.25 out of 5 by 16.
Rated 1 out of 5 by from Specifications mismatch due to new revisionI bought 2 of these tweeters for a two-way project, which notably required a low Fs. They did not at all match the published specifications (at the time of purchase) from Dayton. It was obvious to the ear. There are significants peaks and dips if the frequency response.It seems to be an entirely different revision of the tweeter.It is only recently that Dayton has updated the product sheet.See screenshots. Curves are different, Q values, different. Fs, vastly different.It is nonsense for it to share the same part number and model number ! And, above all, it was utter nonsense that the product specs were not updated at the same time as the product batch.I am highly disappointed in my purchase, because I did not get the product that was advertised (got the revised model, but based my purchase decision on the specs of the old one).The fact that I bought these tweeters from a Canadian reseller only complicates matters more... I ought to get reimbursed, but most likely the reseller will refuse, claiming it's Dayton's fault...Huge loss of confidence in Dayton products

Rated 3 out of 5 by from Good for the priceI have just recieved these tweeters, they have a nice detail in the high end, something the Vifa radiator tweeters were missing, these sound good but when the volume goes up it turns into a mash of treble, these tweeters sound really nice but only at low-moderate levels, they have a similar characteristic to polk audio DB car audio tweeters except these sound a little nicer at lower levels where turned up the polks held all the sounds seperate like it should be, this is all with polk audio db crossovers running probably around 3.5k 12db/Oct.For some reason like others have said, the domes are sticky, i dont know what the go with that is like its some practical joke or something but yes the domes are sticky for some silly reason.

Rated 5 out of 5 by from Paradigm Monitor 9 Replacement TweeterAfter reading that another reviewer used these in Monitor 7s, I put them into a pair of 9s that a friend had blown the tweeters in. I received them this afternoon and I'm listening to them as I type. VERY pleasantly surprised at how good these sound. Working from memory, I'd say they sound better than they did before. Minimal cabinet mods needed. Not the prettiest, but the sound is what counts and the covers fit. Nice.

Rated 4 out of 5 by from Nice TweeterJust replaced original B652 tweeter with the DC28FT-8 and an audio grade 6.7 uF cap. The tweeter sounds wonderful, but totally outclasses the rest of the speaker resulting in poor balance. Maybe need to add a inductor to woofer. Oh well, but nonetheless, a beautiful tweeter.

Rated 5 out of 5 by from WOW. What a difference.Back in '09 bought a pair of BIC Model 1530 speakers (3 way. 15" woofer, 5" mid, 2" tweeter). Instead of a 3 way cross-over, they come with "Speaker Protection Circuitry" that shuts down the speaker due to excessive input or abnormal signals. Big pain in the rear. Decided to put in a 3 way cross-over (Parts Express Part # 260-210) and remove the circuitry. At the same time it was suggested in another review to replace the tweeters with Seas 22TAF/G alloy dome tweeters ($36/each in "11), which I did. Sounded much better in this configuration, but twice blew one of the tweeters. After the second time (a week or so ago) decided to go another route and found these. Just finished replacing and what a difference. Seems to really complement the mid, which is pretty bright, and for that matter the woofer. Better than the prior tweeter. Smoother and, hard to explain, just a better overall sound from the entire speaker. Now listening to Robert Palmer's "Sneakin' Sally Through The Alley" and it never sounded better.

Dayton Audio DC28FT-8 1-1/8" Silk Dome Truncated Tweeter

Looking for a pair of tweeters for my cerwin Vega dx9's. Any ideas?

How low could we go with this tweeter, 1500 hz 2nd order, 3rd order? Trying to find the right one to couple with an 8" woofer so I can have a bit better bass extension without beaming.

Asked by: ibrokeit
I wouldn't recommend crossing this any lower than 1,800, regardless of filter type. I would look at the RS28F-4 if you are interested in crossing that low.

Can I remove the faceplate and mount the tweeter directly to a baffle? The baffle will probably be 1/4" acrylic.

Asked by: EricM621
Yes this is doable. I would recommend a round-over or chamfer around the dome to prevent any unwanted response issues but this should work perfectly fine.

I have an older pair of Sony speakers, SS-U590, would these make a drop in fit?

Thanks MattP for the Ohm L response. Followup Q: the Ohm L sensitivity = 89dB. Do I need to choose a tweeter with the same 89dB sensitivity or higher to account for losses in the crossover? If higher, how much higher? XO will be LR 2nd order at 1,700Hz

Converting 3way Ohm L's (vintage 80s) to 2way. Current Xover stated as 1,700 Hz 1st order BW. But it has 8.2 mF cap (no inductors). All drivers 8 ohm. I'll be recapping. Will this DC28FT-8 work at 1,700 1st order without inductors? thanks for the help

Asked by: maui2025
I would not recommend using this or any of our tweeters at 1,700 first order. This will work at that frequency second order though, which will require a 1 mH coil and that 8.2 uF cap.
