The sinfoni speaker Appasionato  series is newly engineered to  provide accurate sound quality in a slim profile, easy “drop-in”  component speaker solution.                
After considerable research and development, careful  attention was paid to maximize performance in this slim profile design  while maintaining high sensitivity and audiophile worthy musical  reproduction.                
Appasionato’s high sensitivity response allows for  easy pairing with a variety of electronics, even maintaining its  high-end sound with stock electronics; upgrading to Sinfoni  amplification is highly recommended and will result in ultimate system  performance.  Due to the speakers optimized off axis response,  Appasionato’s component system easily achieves high fidelity even using  difficult, but often necessary stock speaker locations. Utilizing a  specially treated pulp cone and a high quality silk dome tweeter, the  Appasionato’s performance is the high-end, audiophile sound expected  from Sinfoni products.                
A real high-end system can now be achieved as a simple  drop in solution while maintaining the vehicles OEM appearance and  rewarding you with exceptional musical enjoyment, for years to come.
