Overview
SEAS H1878-08 7" Aluminum Cone Woofer- 8 ohm (L19RX1)
L19RNX1 is a high-fidelity woofer with a very stiff and optimally shaped aluminium cone. This pushes the cone break-up high up in frequency and avoid any resonances in the working range for a very natural and clean sound.
SEAS TITAN H1878-08 7" Aluminum Cone Woofer- 8 ohm (L19RNX1) w/ Titanium VC Former
L19RNX1 is a high-fidelity woofer with a very stiff and optimally shaped aluminium cone. This pushes the cone break-up high up in frequency and avoid any resonances in the working range for a very natural and clean sound.
A titanium voice coil former with a long copper winding for excellent force transfer, transient sound reproduction and large linear excursion. A unique radial reinforced rubber surround reduces radial resonances and prevents surround break up at large excursions. This combination results in very low mechanical damping for better clarity and brings out the micro details in the music.
An FEA optimised magnet system with precisely fitted copper parts for excellent linearity, high power handling and low distortion.
The extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.
