STI PL 1235
Sti’s Lf drivers has been designed for use as a bass and low-midrange driver in tuned reflex enclosures, in 2- or 3-way systems. When used in a 2-way system, we recommend a 1″ or 2″ exit compression driver to obtain the best sound quality and directional control. The LF drivers combines a high sensitivity value with high power handling capabilities. The curvilinear paper cone, in conjunction with the viscose dampened double half-roll suspension, provides excellent transient response and cone damping. The low inductance coil gives improvements in transient response.
Excellent heat dissipation has been achieved by incorporating air channels in the basket design, between the basket and top plate.
The special treatment applied to the top and the back plate is far more resistant to the corrosive effects of salts and oxidization than any other treatment in use

STI PL 1890
The PL 1890 is a low frequency subwoofer which sets a benchmark in 18" (460 mm) high output transducers. The PL 1890 can be used as a low bass or subwoofer component in either a reflex, bandpass or horn loaded configuration. It provides clean, linear, undistorted low frequency reproduction at very high power levels. The high excursion capabilities of the surround and suspension system, in conjunction with the Double Silicon Spider, enable the PL 1890 to achieve high levels of linear travel while maintaining full control of the moving mass. The high quality curvilinear cone assures smooth response and exceptional strength with maximum reliability under high mechanical stress. It has an extremely linear motor assembly. Maximum flux concentration and force factor in the gap is assured by the unique shape and design of the top and back plates.
STI COAX 12
On the Sti's Coax drivers tThe curvilinear profile LF cone provides smooth response within its intended frequency range thanks to its high damping pulp composition. The Coax drivers are in a balanced coil with a uniform distribution of mass and motive energy and an extremely linear motor assembly. The low distortion and sound quality are further improved by an aluminum demodulating ring that flatten LF impedance and phase with constant power transfer. Equipped with a proprietary hybrid radial tangerine phase plug, the integrated HF compression driver has been designed to give a smooth, coherent wavefront at the horn entrance in all working frequency ranges with an high level of manufacturing consistency.
