DT 100 H
100 DT 26 72 SF FF WA
8 ohm    -   
Order ID: 811827

Ferrofluid version of the WA tweeter. It has got the same qualities as the 811815 such as controlled directivity and very low difference tone distortion (under 0.3 pct). The magnetic oil in the airgap adds viscous damping to the system and increases the power handling. A high quality tweeter for the most demanding systems.
