Dayton Audio ND28F-6 1-1/8" Neodymium Dome Tweeter is rated 4.1538 out of 5 by 13.
Rated 5 out of 5 by from Nice tweeters with good osund stage!I bought these tweeters to replace some 3/4 silk domes that came with a pair of satellites that I had bought and am much happier with these! The originals didn't sound bad, but there were some problems with the 3/4's. The 2nd order crossovers that came with the speakers were crossing at about 3500 Hz. And, for some odd reason, they were lacking in lower high areas. These tweeters can go well down below that and are a perfect size for small bookshelf or satellite speakers. Luckily the 6 Ohms on these new ones matched my originals. And, since they are larger and have a more pronounced dome, they have a better "sound stage." (The 3/4's sounded too "point sourced.") There is also more detail in the lower highs, like acoustic guitar. They are fabric domes... they are very smooth! So, if you are used to listening to Mylar 1/2 or 5/8 dome tweeters; since those are more shrill, this could be why many reviews say they suffer on the high end. If you like the sound of the Mylar's, I wouldn't recommend them. However, if you're looking for a more smooth, natural response with good presence, detail and wider soundstage... these would be good. Things to consider, though: These are 6 Ohms. If you are planning to just drop them in..? check the Ohms on the ones you are replacing. IF they are 8 ohms or 4 ohms, the crossover will be completely off! You will need to change the capacitor (s) (and/or inductors) to compensate for them, or your mid to upper highs will either be too low or too high in volume! Off the shelf crossovers of 8 or 4 ohms won't work properly, either. PE has crossover components and boards so you can solve that problem. Other than that, they are great for small speakers if you want more room filling sound in the high end...

Rated 3 out of 5 by from Not what I expected.Just arrived today. Hooked them up and... :( They are very lacking in the twinkle department. In their defense, I don't think they sound bad, but they don't extend as high as I'd like. They sound fast, light, and airy but, as other reviews have pointed out, it's going to need some tweaking at the source.

Rated 4 out of 5 by from Worked great in my JeepI installed a pair of these in the sound bar of my Jeep. I just used a 6.8uf cap for a crossover. They made a huge improvement!

Rated 4 out of 5 by from Replacement for Sony SS B-1000I have two sets of Sony B-1000 speakers - don't ask. One set is using the Vifa BC25SC06-04; one has these Dayton ND28F-6 tweeters. The Daytons do not have as strong an output as the Vifa in the upper octaves, but I believe they are a better timbre match to the Sony "woofer" -actually a full-range. Also, the Daytons can be crossed lower.For the ND28F-6, I used a second order high-pass at 3000Hz. I inserted a 1 ohm resistor in series to knock it down 1.4db from an spl of 88.4 down to 87db - same as the Sony full-range. It also raises the electrical resistance to 6.6 ohm, which is about the same as an average nominal 8 ohm speaker. That makes the calculation for the crossovers/filters a lot simpler.The result isn't too terrible, and I can always boost the high end with tone controls, if I think it is necessary. As is, though, it is smooth and easy to listen to. The pair with the Vifa tweeters can get intense on some music. The Daytons are less fatiguing.

Rated 5 out of 5 by from Very Smooth and Clear TweeterI bought a pair of these to replace the stock tweeters on a pair of Samson Resolv 80a studio monitors. The main reason i chose these was because the original speakers are not available, and the measurement on these speakers fit the stock mounting specs on the Resolv monitors. I was very happy with the fit and these speakers looked better than the original metal domed tweeters, but the real surprise came when i powered up and put some signal to them. They are silky smooth sounding, not harsh at all. They are not bright, but they are very accurate. I have not used them enough to get them broken in yet, but they sound really good already. All in all, i would say these are a couple steps up in sound quality from the original tweeters. The only downside was the originals had a heatsink on the back of them, but i simply took the heatsinks off the originals and super glued them onto the new Dayton tweeters. That should help keep the temps in check during long mixdown sessions and extend the life of these tweeters. If you need a decent set of tweeters, and these fit you application, don't be afraid of these. The only thing i would get for them is some protection for the dome, depending on your application. I didn't bother to put any on the studio monitors, but i don't have any kids around who would be tempted to touch them..!

Rated 5 out of 5 by from More than expected at this price point...Needed a pair of tweeters to install in the doors of my B5 (1999.5) Audi A4. Took a chance on these and they've far exceeded my expectations... and they fit into the factory space in the door PERFECTLY if you remove the faceplate.I'm running them active, crossing them over at 2.2K with a 24 dB slope. Really brings home the top end and matches up incredibly well with the Dynaudio drivers.System:Alpine 9887JL Audio 300/4 and 500/1Dynaudio MW150 (front doors)Alpine 12" R series sub

Dayton Audio ND28F-6 1-1/8" Neodymium Dome Tweeter

Is this a suitable replacement for the tweeters in the old B652's? Also, would the Beston round tweeter RT003C be a suitable tweeter for these speakers? Both will fit the cutout easily.

Asked by: jackie4me
As long as they will fit, or you can modify the enclosure, they will work but you will most likely need to change the existing crossovers to get the most from the new tweeters.

How does this compare with the Dayton ND20FA-6?

I really like the ND20FA-6 and was wondering if this has the same sound characteristics.
Asked by: Dave80
It's actually the better tweeter - better high end extension, and because it's 3/4" - it will have better dispersion characteristics. It has lower power handling capacity though - so make sure you design your crossover correctly. If 3500hz - 24db/oct. If around 7000, 6db/oct. 5K should be okay. I prefer 6db crossovers as they keep the drivers in phase...

6 ohm with an 8 ohm crossover?

will this work with the Dayton Audio XO2W-3K 2-Way Crossover 3,000 Hz
Asked by: ericjnelson
This will work, the crossover point will be shifted to around 4,500 Hz.
