Dayton Audio ND20FB-4 Rear-Mount 3/4″ Soft Dome Neodymium 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!
