LA PASSION DO HAITT PARLEUR

1" - SOFT DOME ■ 25 mm

TWQ25A0 ITWEETER

"Catenary" profile Extented frequency response Replaceable voice coil assembly 1" impregnated textile dome Solid aluminium face plate Good efficiency - 90 dB / W/m.

Dome profil "chainette"Bandę passante etendue Equipage mobile interchangeable Dóme 25 mm textile Face aluminium massif Bon rendement - 90 dB / W/m.

The "catenary* profile on our textile diaphragm provides maximum stiffness at the tip of the dome. The moving mass performs more like a perfect piston with no out of phase break up at the tip. The results are clear, smooth and transparent sound reproduction with good efficiency from 1 kHz to 20 kHz ± 2 dB and high power handling capacity of 55 Wrms. Easily coupled with 2nd order crossover as shown Fig I . Two crossover points are suggested for adequate power handling.

Le profit "chainette" de ce dóme textile procure une rigidite maximale au sommet du dome. I ensemble mobile a done une comportement proche du piston parfait, sans gónćration de modes parasites. II en rćsulte une reproduction son ore claire. delicate et transparente. le rendement est de 90 dB de 4 kHz ^ 20 kHz ± 2 dB, la tenue en puissance confortable (55 W rms>. II peut £lre fibre au second ordre (12 dB/Oct) selon le shćma Fig I . Deux frequences de coupure sont proposers afm d'oblenir la tenue en puissance adequate.
