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 4.3226 out of 5 by 31.
Rated 3 out of 5 by from Performance matches priceFor the money it is a good tweeter but for my project, I wished I'd have spent a little more on a better tweeter. It is a tad harsh at higher volumes.

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.

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

I have wonderful old custom car speakers: 5 1/4 woofer, crossover and the old Vifa\Tymphany D19TD-05 mounted high in the doors. The Vifa tweeters are not going to fit into my new car. Would the ND20FA-6 work reasonably well as a drop in replacement?

Was the new stock really delayed from late December 2014 to early March 2015? I was hoping to get a pair of these for some Overnight Sensations MTMs. Being an overseas customer I need everything to be available at the time of purchase.

Asked by: Jimjim
The current ETA for this tweeter (as of 1/5/2015) is January 9th. That is a Friday so they may not show up in stock until the following week.

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.

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.
