The Silk dome is the smoothest. Always gentle and forgiving, this tweeter emphasizes the music and avoids noise and artifacts that may embed some source material or be characteristic of less than perfect amplifiers. Very low listening fatigue and an easy quality that puts an emphasis on the system╣s midrange.
The Aluminum is more aggressive at retrieving fine detail. Cleaner and more revealing than the silk but more critical also. The lower end (in a tweeter) is perhaps the lowest in distortion. The all-around choice.
The Titanium is the speed demon. For those who demand the maximum air and energy the Titanium takes the top end into the violet. Very critical and revealing of high end details.
The trio may be snapped into the same housing for an instant A-B.
Free yourself of fixed restrictions and introduce the possibility of choice into your life.
