1 inch ultra hard ceramic dome tweeter - Cell Concept Driver.
The C25-6-158 is a 1 inch tweeter with an ultra hard (Sapphire) ceramic dome in a 58 mm cylindrical body. This tweeter is the smaller brother of the C30-6-358 .
This audiophile Cell Concept tweeter utilises a special clamping technique that provides easy and discrete mounting to frontplates / baffles; for full details please download the mounting datasheet from the bottom of this page.
A unique FEA optimized underhung motor system with vented aluminium voice coil former and double neodymium magnet guarantees low energy storage, excellent heat transfer and high excursion capability for low power compression and ultra low distortion around 0.07% @ 2.83V and 0.5% max. @ 110dB. The new designed soft fabric surround centers the moving parts with unrivalled linearity.
The dome breakup is above the audible range and well controlled, no dome aperture cutouts or further damping is required.
We recommend a crossover frequency above 2000 Hz.
