喇叭新玩法

fireface

今日介紹一款專業用喇叭比較普遍既玩法, 首先今日既主角Fulcrum acoustic RM22, 此款喇叭適合用於錄音室, 戲院, 家庭影院.
由於呢款喇叭體形較大, 要有一定空間才適合.



專業喇叭品牌如MEYER, NEXO, D&B等都用自家品牌speaker managment system. Fulcrum acoustics則可以選用指定品牌DSP作喇叭
的電子crossover, eq, delay等設置.

點解要用dsp set crossover, eq呢? 簡單解釋就係可以避免一些phase上既問題, 以下係廠家對dsp一些解釋, 詳細資料可去網頁研究

"At Fulcrum Acoustic, we see the DSP algorithms as being part of the loudspeaker design – and this is not just a semantic distinction. Rather than using DSP to mitigate the shortcomings in a finished design, we include DSP techniques in the design process from the very beginning.

All too often loudspeaker design has been a matter of compromise. As much as we loudspeaker designers would like our high frequency horns to have perfect coverage patterns, we have often settled for imperfect coverage in order to achieve aesthetically pleasing transient response. In the low to mid frequency range, we would love to harness the efficiency of folded horns, but we have settled for straight, exposed-cone horns because their better-damped transient response produces more natural sounding vocals. We would like every loudspeaker to have coaxially positioned sources, but we have found that some coaxial designs present unsolvable acoustical challenges or simply are not capable of producing acceptable sound quality."
