## Description

SEAS Prestige T18REX/XFC (H1353) 7" Coaxial, Clear Cone The Seas H1353 has a PP/TPX based cone that matches ideally with an adaptive rubber surround. The result is an outstandingly smooth frequency response from the mid woofer. A coaxially arranged pre-coated fabric dome high frequency unit with a low resonance frequency, integrates with the cone driver to a point source. The cone of the woofer acts as a horn loading for the tweeter, and the chassis of the dome unit represents the throat of this horn. This unshielded version is ideal for smaller enclosures. F3 of 60Hz in 0.3 cubic foot enclosure with a 1.5" diameter vent by 5" long. Crossover available separately. This speaker is an excellent choice as an autosound speaker as well.
