The Seas L15RLY/P H1141-08 is a 15 cm (5’’) cone driver, developed for use as a long throw high fidelity woofer or woofer/midrange unit.
Stiff, yet light aluminium cone and low loss rubber surround show no sign of the familiar 500-1500 Hz cone edge resonance and distortion associated with soft cones.
Large magnet system , together with very long, and light weight copper clad aluminium voice coil allow for extreme coil excursion with low distortion and good transient response.
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 resonances to a minimum.
