Transcription of MIDRANGE 12M/4631G00 - Scan-Speak
1 MIDRANGE 12M/4631G00 . The Revelator midranges are well known for their sliced paper cone technology. The slices are filled with damping glue, which dramatically reduces break-up modes in the diaphragm. In combination with Scan-Speaks low-loss linear suspension it represented a breakthrough in MIDRANGE clarity and overall smooth frequency response characteristics. KEY FEATURES: Excellent MIDRANGE reproduction Sliced Cone (Controls Cone Breakups). Low-Loss Linear Suspension High Output 89dB @ 2,83V.
