Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeter
Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeter is rated 4.6239 out of 5 by 109.
Rated 5 out of 5 by from Use as an ambience tweeter.Bought a pair for use as a sort of ambience tweeters (James Romeyn's Late Ceiling Splash concept where it's on the floor behind the main speaker aimed upwards), so it's only providing secondary effects but seems well made and works perfectly. Delivery was very prompt with no issues.

Rated 5 out of 5 by from Great sounding tweeters.I bought a pair of the 275-070 tweeters for an old pair of Dynaco A-50 speakers. I read two positive reviews where this tweeter was used on the Dynaco A-25 which uses the same Seas H-087 tweeter. These tweeters sound absolutely amazing.

Rated 2 out of 5 by from I was less than impressed - sorry!!The Dayton DC28-f tweeter had great reviews from multiple sources, so I tried it in an MTM configuration with rather nice mid-woofers of another brand. I ran into several "less than thrilled" moments with these tweeters. All the while, I thought of all the dozens of other tweeters I have used in building cabinets and crossover designs.... this tweeter is NOT a bargain at the price. There are much better tweeters out there, for the same bargain price, that provide superior sound and craftsmanship.1. The flange is rather large at 110mm dia, and cannot be swapped out with another brand quite easily, so once you route out the countersink for this tweeter, you are stuck having to use this tweeter.2. The flange is FLEXIBLE plastic and with only THREE mounting holes, at 110mm dia, this is just ridiculousness... there needs to be 4 or even 5 mounting holes for this config, as the flange will bend as you screw it to the baffle.3. The dome attracts a lot of dust and dander and anything that will stick to it.4. The terminals are both poorly placed, and poorly constructed. Extra fabrication is needed to route out the space needed to install the speaker terminals into the cabinet baffle, reducing the area that would have been used to form an airtight seal.4b. The tweeter terminals are rather junky and can and will come apart if they get bent installing into a cabinet, and they lose grip with the crimp connectors frequently. They are a few mm off from the size of other tweeter terminals...sort of an overstock odd-ball size to save money. They will also no doubt fall off, if soldered a few times (I don't solder wires to connectors this fragile - I used crimps)5 . The sound is not the greatest in certain frequency regions... as the tweeter has two significant dips in response, around 3000hz and 5000-7000hz. Both tweeters had these same dips, and the 5-7khz dip was difficult to deal with.6. Crossing this tweeter at below 2200hz in either a 2nd or 3rd order crossovers, can and probably will cause problems in sound reproduction. If you add a zobel to it, the response will dip by a few DB from 4khz onward....but the sound cleans up a bit better overall.I would not suggest this tweeter to anyone that took a lot of time and effort to build a nice cabinet and crossover. Look elsewhere (tymphany/vifa/peerless), Seas, SB Acoustics, all have better budget tweeters in this price range.7. The T/S measured parameters did not match manufacturer specs very closely. The resonant Frequency was also higher on both tweeters, as measured by DATS.8. Spend a few more bucks and go SEAS or if buying from Parts Express, go Dynavox. SOLID tweeter. aluminum flange, great sound and modeled after the older premium Dynaudio tweeters. It also has a very similar measured SPL curve. so in affect, same sound reproduction, just much more articulate and clearer than this budget tweet from Dayton.If you are installing this tweeter into a budget system, then yes, it will probably sound better than the budget mass production tweeter it was replacing. That's the only time I would suggest wanting to use it for a speaker project.

Rated 5 out of 5 by from Great tweeterI bought these to replace blown tweeters in a pair of Cerwin Vega e712's.. Seeing I could get direct replacements these were close.. They sound great.. No disappointments

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.

i need to replace a tweeter on a polk tsi 400 can a use this tweeter

Asked by: audiomusic
I unfortunately do not have any information on that particular driver. Generally I start by making sure it will physically mount by checking the cutout in the box and face plate size. If those match up, I check impedance. If those are all good it should work.

I currently have a 2x50w sure amp ready to power these and the HiVi 5" M5N's in a two way set up. Will this be enough or should i go with a 2x100w amp as the specs say these speakers can combine to handle more than 100w total? Thanks

Asked by: GoBucks
The power handling of the speaker system is determined by the woofers used, so the speakers will only handle 35 watts RMS. The 50x2 will be perfectly fine in this case.

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.
