Dont 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 dont 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!
