Heco Superior Allegro 350

剛剛從親戚舊物中收留左呢隻野，但可能因為實在太舊，所以一D實用資料都 search唔到，所以想睇下有無ching知呢隻野掂唔掂，如果用來睇戲O唔OK?
因為我無其他喇叭比較，所以都唔知佢算好定唔好...

應該唔大問題既, 唔知你用咩AMP , 舊式喇叭可能速度反應唔夠配合現時高清音效 , 都係駁黎聽聽, 耳仔收貨為實 , 可接受效果既咪用囉, 或用黎當後置用都可以

It's 4 ohms speaker, don't turn 605 volume too high when play, otherwise may be trigger protect circuit.{:6_166:}{:6_166:}

babuwa hing, actually I want to know more about this too, on Onkyo 605, I set my sepakers to 6 ohms, becasue my center, surround are 6-8 ohms, so if I connect this 4 ohms front speaker, what will the limitation be? What is "trigger protect circuit"? Can you explain more?

    only follow your normal listening level should not have big problem, actual limit were vary from machine (no more than 50% of full scale should be safe). trigger protect circuit of your amp is not a bad thing since it's avoid your amp burn if overload and it can be recover after, no need too worry.{:6_210:}

After change the front speaker should do mic auto-calibration again since sound level setting will be different.{:6_142:}

ohm 數越細 o既喇叭, 就越需要更加大 o既電流去推動對喇叭.

babuwa 兄 o既意思係: 如果你架onkyo 605 唔係好推得郁對喇叭, 就唔好係咁一味扭大聲, 因住會燒機!!{:6_197:}

如果真係推唔郁對喇叭, 都係時候考慮下入隻power amp.

the Allegro 350combines two heavily coated multi-layer cellulose bass/midrange drivers with a single tweeter placed centrally between them. In this 2-way design, the lower driver is rolled-off above 120Hz whilst the upper one continues to the main 3kHz crossover point.
