8XC20 garsiakalbis 8" 40Waes 8 omų

Описание

This 8" coaxial loudspeaker has been designed in order to achieve an excellent compromise between power handling, efficiency and weight. Its low frequency unit features a 2" (51.7 mm) aluminium voice coil which handles 170 w AES, while the high frequency unit features a 1.75" (44.4 mm) edgewound aluminium ribbon voice coil which yields a 40 w AES power handling.
The combination of these two drivers give as a result an extended and linear frequency response with low distortion and high efficiency. Moreover, this dual loudspeaker has a relatively low weight (3.7 kg.) that makes easier to fit it with a compact bass-reflex enclosure.

Key features

• 8" bass loudspeaker and 1" exit compression driver combination
• High power handling: 170 w AES (L.F. unit) and 40 w AES (H.F. unit)
• Extended and linear frequency response (65-20000 Hz)
• High sensitivity: 95 dB (L.F. unit) and 105 dB (H.F. unit)
• Low weight (neodymium compression driver)
• Bass loudspeaker designed for compact bass-reflex cabinets
