Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeter
Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeter is rated 4.6346 out of 5 by 104.
Rated 4 out of 5 by from Good value priced tweeterAfter critical listening and switching to a NAD preamp I must confess these are thoroughly acceptable tweeters. High vocals get a bit rough around the edges as the volume control gets nudged to 7 and higher. That may change some when the system gets moved from a rather small listening space to a room approximately 15' X 26'. Really looking forward to that listening experience.

Rated 3 out of 5 by from Questionable build qualityI just bought a pair of these for two mid 1980s Technics speakers that I am rebuilding. The main reason that I chose them was for all of the positive reviews and that they were the only tweeter available that fit the cabs without major surgery. Keep in mind that I have not heard them play music as of yet. These are just my first impressions of them.1. The terminals are very fragile. I would suggest opening up your connectors a bit before trying to attach them. Any reasonable pressure at all will break the mounts.2. Not a fan of the bug-eye design. The dome protrudes a good 1/4" beyond the face plate. This makes it very susceptible to damage from anything coming into contact with the speaker baffle. Besides, it just looks goofy.3. This is my biggest concern. There is a large dip in the frequency response between 7k and 9k (see image). Both tweeters measured almost exactly the same.So far I have modeled them into a 3-way 2nd order crossover -- crossed at 4k. Parts have been ordered and I will start testing the design this week. I'll update this review when I have results and a final opinion.

Rated 4 out of 5 by from Couldn't be betterThese are fantastic sounding tweeters. I am using them in my first build and they are so crisp and clear, but yet don't over power my mids at all. The only negative thing I have to say is that the silk dome is actually coated with some sort of a rubbery substance and they are slightly sticky to the touch. I only mention this because my drill kicked up the tiniest bit of dust which landed on one of them. I tried to blow them clean, but because of the slight stickiness, the dust will not blow off. Like I said, it is only a tiny bit of dust, and for my application it doesn't matter, or affect the sound. However, if you are flush mounting these, and one gets dust on it, it will be noticeable because sawdust is light colored. Get any dust on these and it is not coming off unless you are willing to potentially damage them.

Rated 5 out of 5 by from Perfect replacement for Marantz Imperial 6I purchased these a year ago as a replacement when rehabilitating a set of Marantz Imperial 6's and still love them. A significantly better choice then the standard phenolic ring tweeter with softer highs and better presence.Love love love these tweeters

Rated 5 out of 5 by from Dayton Audio DC28F-8 1-1/8" Silk Dome TweeterI have to say I was skeptical about purchasing the Dayton DC28F-8 even after reading all of the excellent reviews. I wanted a Euro sound but I needed the X-over to be at 1.8kHz for a 2 way system. After miking the tweeter I found the response curve to be right on spec and created a 3rd order X-over at 1.8KHz. Applying it to my system was effortless and the overall sound curve looked excellent. When I gave my new speakers the final listening test I have to say I was amazed at the spacial and smooth sound quality that the Dayton DC28F-8's put out! I mean they sound great! Plastic, yes – low cost, yes but there is no need to spend more money to get this kind of sound.Very impressed!

Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeter

I'm thinking of replacing some no-name tweeters with these, but the existing crossover is currently a 2nd-Order Linkwitz-Riley at 2500hz highpass. Is this too high or do you think it will blend nicely?

Asked by: mastertee31
2500Hz 12dB crossover will be fine.

Can you recomend a midrange that match's well with the Dayton DC28F-8 silky and the Dayton DC200-8 8" woofer? The midrange cannot be larger then 31/2" in overall diameter. Maybe a truncated 4".

How can I test the polarity on these?

Asked by: Lerneg
There isn't a very good method of testing polarity on a tweeter since the normal battery test won't yield much of a result, and can be dangerous for a tweeter. The polarity is marked in red on these. If the marking is no longer visible, the left terminal as pictured on our website is positive.

Would these work well with the GSR 8PR-8 (Part  # 292-428)? if so, which crossover should I use?

Asked by: kvdenney
This should work well with a low crossover point. The lowest we offer is 2kHz which you can see below.http://www.parts-express.com/dayton-audio-xo2w-2k-2-way-speaker-crossover-2000-hz--260-140

I am considering using this tweeter with the Dayton DS175-8 6 1/2" woofer. Woofer response is up to 4500 Hz. Tweeter response is down to 1300 Hz. Within that range, do you have a recommended crossover frequency for this pair ? Why ? thanks

Asked by: bwmac256
I would recommend a crossover point of about 2kHz for this combination. The upper end of the woofer starts to droop a bit and the lower crossover point will help eliminate beaming at higher frequencies.
