Description
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 minimise 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!
Features
- Compact neodymium motors have low stray field
- Ferrofluid enhances power handling and helps damp resonance
- Rear-mount design minimises housing size
- Centre-to-centre spacing as low as 1-1/2"
- Great top-end air and sparkle
