Yamaha NS-AW150 Indoor/Outdoor 2-Way Speakers:
- 5" high compliance polypropylene mica filled woofer
- 1/2" PEI dome tweeter
- Wide frequency response: 55Hz - 40kHz
- 120W maximum input
- Wall mounting bracket included
- Vertical or horizontal placement
- 5-way binding post speaker
The speakers, which are sold as a pair, each use a 6.5-inch high-compliance, polypropylene, mica-filled woofer and .5-inch PEI dome tweeter. The drivers are optimized for high rigidity but low mass, giving them reasonably high sensitivity (80 dB with 2.83V at 1 meter), another way of saying modest amplifiers won't have much trouble driving them. Their acoustic-suspension cabinets are sealed to prevent undue resonance or tubby, tuneless bass, which often results from low-cost ported designs.
