This kit comprises:
SEAS U22REX/P-SL H1659-08. Specially developed by Seigfried Linkwitz/SEAS for this design. Prestige 8” Lower Midrange/Woofer with an injection moulded metal chassis, intended for bass reflex and transmission line designs.
Featuring a New Curv cone, a woven polypropylene with excellent internal damping together with perfectly matched moving parts gives a smooth, extended frequency response. Bumped back plate in the magnet system together with a high temperature voice coil wound on an aluminium voice coil former giving low distortion and high power handling capacity. A heavy copper ring below the T-shaped pole piece reduces non linear and modulation distortion.
The bullet shaped phase plug reduces compression due to temperature variations in the voice coil, avoids resonance problems which would occur in the volume between the dust cap and the pole piece and increases the long term power handling capacity.
An extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment, and large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.
SEAS MU10RB-SL H1658-04. Specially modified by Seigfried Linkwitz/SEAS for this design. Prestige 4” Midrange/Full Range driver offering an extraordinary performance and sound clarity, featuring a New Curv cone, a woven polypropylene with excellent internal damping together with perfectly matched moving parts giving a smooth, extended frequency response.
A high loss natural rubber surround makes this driver perform its best as a midrange. The large, open weave fabric spider reflects very little acoustic energy to the cone, and offers excellent stiffness linearity.
A stiff and stable injection moulded aluminium chassis keeps the critical components in perfect alignment. The pole piece is prolonged forwards and equipped with a deep drawn copper cap to ensure excellent linearity in the force factor and coil inductance.
SEAS 27TFFNC/G H1396 Tweeter is a compact design neodymium magnet tweeter, with 26mm Sonolex precoated lightweight fabric diaphragm and suspension enabling very tight production tolerances and high consistency. A wide roll surround together with a double chamber magnet system results in a low fundamental frequency. Very low magnetic stray fields make this unit suitable for A/V systems. Uses Ferrofluid for high power handling capacity.
