Product Details

Dayton Audio ND20FB-4 Rear-Mount 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!

Rated 5 out of 5 by from Infinity P363 are cheap and no warranty these fixed themMy six month old Infinity P363 have blown the tweeters in all four now, Infinity JBL and Harmon Kardon dont have them and must continue to wait for warranty service three months now. These tweeters can be placed in them and sound better. Stay away from plastic and garbage from Infinity, JBL and Harmon Kardon. They sell but cant service. Thanks to these speakers I have one pair up and running and I will order another set of tweeters for the other pair. ThanksParts-express

Rated 4 out of 5 by from good small tweeterI have used a few of these in different set ups. They have a nice open and airy sound and have decent efficiency despite their size. I am very sad to see the price go up so much on them though.

Rated 4 out of 5 by from MazdaspeedI purchased 2 of these to replace the factory Bose tweeters in my Mazdaspeed 3, after reading others' reviews. There is a noticeable difference and improvement in sound #highs# quality. Obviously not night and day, but enough of a difference that it was worth the approx. $35.00 I spent on the 2 tweeters and the 2 Capacitors.

Rated 4 out of 5 by from Quite goodVery nice little tweeter, but I did notice some sibilance compared to others I've tried. Not to bash it though, it is pretty good and clear.

Rated 5 out of 5 by from Exceptional ValueI was recently given a pair of Polk S4. Looking to increase high frequency detail I bought a pair of these and mounted them on rear of the enclosure with a 1st order crossover at 10k. Not expecting much my chin hit the floor. Except in the bass the S4 now sound better than my Klipsch KG4 and Pinnacle PN8+. There’s tons of additional definition without being overly bright or spitty. If you are looking for a tweeter to Xover at 3500Hz, look no further. These little tweeters are amazing both in price and performance

Which cap should I use for a 4000Hz xover?

Asked by: okiefz1
I would not recommend only a cap if you need to cross this that low. Even with a second order filter the recommended crossover is no lower than 5,000 Hz. I would recommend the simple high pass filter below.

Does anyone know the cutout size for this tweeter?

Asked by: dewitteridder
For this tweeter in a rear-mount application, you'll want a cutout of about 1-7/16".
