Product Details

Dayton Audio ND20FA-6 3/4" Neodymium Dome Tweeter

Don't let the low price fool you! This versatile tweeter is a huge step above the average "budget" tweeter. Conceived with line array thoughts in mind, it is finally possible to achieve the inter-driver spacing needed to minimize comb filtering out to nearly 20 kHz. But its uses don't stop at line arrays-- it has the sensitivity, smoothness, and power handling to individually do a two-way with most small woofers. Or, use it in an A-pillar in your car as a great inexpensive component tweeter. Give them a try for your next budget or micro speaker-- you will be pleasantly surprised!

Dayton Audio ND20FA-6 3/4" Neodymium Dome Tweeter
Dayton Audio ND20FA-6 3/4" Neodymium Dome Tweeter is rated 4.3667 out of 5 by 30.
Rated 4 out of 5 by from Screamer'sBought these a couple weeks ago with the Neodymium 5 1/4 Mid bass drivers. I used some bass blockers with them and they are super clear and great sounding!

Rated 5 out of 5 by from Better than expectedUsed this to upgrade an old Lafayette Criterion 2x along with a Peerless 5" woofer and 2.5kHz crossover (see review elsewhere on the PE site). I like the press-fit mounting ease (had to make a matching hole in a metal plate to cover the old tweeter opening. Overall sound is silky smooth and a huge improvement over the original.

Rated 5 out of 5 by from Great choice. But, why this price increase?This is arguably the best budget tweeter I have ever tested. Compared to large plate silk tweeters, it is impressively smooth although with heavy sound. I have been buying this tweeter for a long time, I have more than 10 pairs and I recommend it to everyone. But I used to pay 7-8 $ a tweeter, and now the price is 17$???!! It would be worth it even if more expensive, but now I can´t afford to buy a lot of them. If you are willing to use them in your car audio system, tha is the best option available, topping the majority of the small plate tweeters out there. Impressive

Rated 5 out of 5 by from Very smooth tweetercompact mounting allows for close alignment. Hard to rig as a replacement for full size magnet and baffle tweeters, but if you have a 1 and 5/8" hole saw or auger bit, its not a problem.Great sound, hard to find 6 ohms

Rated 5 out of 5 by from Not impressed untill I heard them!When I saw the size of the box I thought are you kidding me. What did I order? Then I hooked them up and had to eat my words. From this tiny little driver the sound was a-ma-zing! Very smooth and and natural , well balanced and for the size, impressive! I can't complain, they were almost free thanks to the free shipping offered by PE. My order was here in 3 day despite a Monday Holiday. Thanks again PE for an affordable solution.

Rated 5 out of 5 by from Terrific tweeterI'm used to expensive tweeters, ribbons and high end domes. I needed a 6 ohm tweet and this little guy exceeded my expectations - flat response and smooth sailing. If it goes low enough for your design it's gotta be a best buy. I'm using 12dB @ 3.8K with no problems. Hard to beat for $8.

Capacitor to protect these tweets?

How many uF do I need in a capacitor to high pass these tweeters at 4kHz OR 6kHz?Thanks in advance for the reply!
Asked by: Syaoran
Tweets should typically be protected by a 12 db filter. (2nd order). Some tweets specify a 3rd or higher order. You might be able to get away with a first order when you cross it at 6khz.My crossover calculator is probably completely broken. There are several web-based calculators out there I suggest you try one of those. The only trick is that you need to select what filter type you want, I like the Butterworth filter, others like the Linkwitz-Riley. There are many issues involved.

Calculating crossover frequencies

How would I go about choosing which filter components I should use with these tweeters?Do I plug in the Re to a calculator, or 6 ohms, or 8 ohms?I need two things to use a calculator and that is Resistance and Frequency. I know the frequency I want to cross these at, but I'm not sure what value I should use for resistance...
Asked by: Syaoran
The Resistance (Re) is 5.2 Ohms. The Impeadence (Z) is 6 Ohms. The Crossover component "wizard" doesn't list 6 ohm impeadence drivers, so for any given frequency, you add the 4 and 8 ohm values in the tables and divide by 2. This isn't a "precise" answer, but like hand grenades and atomic bombs, it's usually "close enough". There's alot more other "stuff" that happens with a speaker that makes more difference than this. I've played at speaker building since I was about 10, and I know I don't know more than I know!;)

How well do these do off-axis?

Asked by: Geoff
For information of this type, you can get manufacturer graphs and data in the manuals and resources area on the same page just to the right of the product description. From use and testing, this driver has fairly good off axis response, generally above 6k the response drops off as you move away from dc. Most notably 10k - 20kHz. But in listening, I personally prefer slightly off axis as many tweeters of this type can be overly bright on axis. This driver is less fatiguing, and is more open and airy, than other "budget" tweeters.

Im trying to make a small speaker project and this is the only tweeter that will fit, so im going to put two 4 inch woofers PN 292-404 with a 1.5 MH coil PN 255-052 what capacitor should I use now heres the thing. I will be using this on the Sherwood RX-4109 receiver PN 252-230 and it will only accept a 8 ohm load or else it overheats and shuts off but these are 6 ohm so will it just get warm or still shut off
Asked by: speaker freack
With a tweeter like that you will want to use a small cap, something like 2.5 or 3 uF. Crossing the tweeter this high will not hurt the receiver, there is very little current draw at those frequencies.

I have them in use with a Dayton DC160-8 and a RS52AN-8 2" Dome Midrange. I am x-over at what I believe 650/8000. Can I attenuate the tweeter with Ωs to tone it down. I had to add 8Ω to the mid and that helped. Or do I need different x-over points.tweeter:21.54uF/0.41mHmid: 21.54uF/4.22mH 0.41mh/1.75uF (bandpass)woofer: 4.21mH/15.76.IN a .57 cuft box tuned to 45hz. Bass is ok. The rest is just too much. Tweeters are mounted in a baffle-less "egg" setup
Asked by: CowboyintheJungle
Usually, a resistor will lower the volume w/o changing the crossover point "IF" it is inserted between the crossover's input stage and the high pass filter. An 8 ohm resistor will decrease the volume of this 6 ohm tweet by about -3 or -4db. A 16 ohm would be around -6 or-7 db. Check PE's "building crossovers" or "building loudspeakers" for the exact numbers. You can always use a pre-made variable"L" pad for this as well.

What size disconnects should I use with these?

Asked by: Mike985
These are 1/8" wide spade lugs, so you need 1/8" 18ga minimum slip-on lugs, crimp or solder.As a rule, I solder all speaker connections and restrain wiring with tie-wraps to the speaker frames. This does not require lugs, but mainly for troubleshooting; knowing the speakers are soldered, a failure [no sound] is likley something else [on the outside]. This goes especially for HT ceiling and wall installations.
