Proel' s TFLV/ TFL flying trapezoidal speaker series is a line of enclosures suitable for installation or touring use, available in hard epoxy texture finish with extremely rugged and anti-scratch coating, or in compact class 1 carpet. The cabinets, designed asymmetrically for wedge monitor applications, are made of 18 mm birch plywood, incorporate a thick metal grille, stand adapter and ergonomic carrying handles for easy transport. Commercial M10 threads/ eyebolts guarantee maximum enclosure suspension facility. High quality woofers feature ISV¢â (Interleaved Sandwich Voice coils) and die-cast baskets with double ventilation design for improved heat dissipation and to reduce power compression. The optimised mechanical excursion is granted by a unique DSS¢â system (Double Silicon Spider), which controls the linearity of the transducer. Low distortion and excellent sound quality are furtherly improved by a DDR¢â system (Double Demodulating Rings). Custom high frequency compression drivers feature titanium diaphragms, flat aluminium wire voice coils, low distortion and extremely good frequency response. Proel's own SWG¢â (Spherical Wave Guide) dispersion horn has a coverage of 70¡ÆHx70¡ÆV and allows uniform dispersion and clear acoustic response. The TFLV/ TFL speakers feature 12/ 24 dB/ oct passive crossovers with electronic protection for permanent reliability under stress. An external Full Range/Bi-Amp selector allows use in multiple speaker systems. Two professional 4-pin SPK4MP connectors guarantee secure speaker cable locking and excellent power transfer. All Proel speakers are tested according to the AES standard power requirements; all electronic devices are built according to CE norms. A complete series of hardware and accessories is dedicated to the TFLV/ TFL speakers: stands, wall brackets, steel cables, eyebolts, protection covers and professional speaker cables, for the most versatile indoor or outdoor use.
