比较有名的铝带和气动高音国外的DIY 有过比较。
RAAL 铝带,RAVEN 铝带,Mundorf AMT 的。
Alex originally designed to use Raven 2.0 as the tweeter which is a reasonable tweeter by all means. However, it lacks in dynamics and while it does not sound harsh, it doesn’t give the dynamics that I like. The original design also has the faceplate too close to the cabinet edge and causes significant diffraction problem. Raven also has a wrong tonal balance and Alex “tried” to fix the problem by loading it with a horn faceplate. However, compared to RAAL, Raven still sounds wimpy in the low end.
Alex moved on to use Mundorf AMT transducer which sounds better than Raven. But still, while it is dynamic, it is less refined and less balanced when compared to RAAL. Compared to RAAL, Mundorf sounds harsh. RAAL belongs to a different league, there is no comparison, I am sorry. So, for my new speaker, I will stick to RAAL. Scanspeak D30/6600 did come to our minds as this will allow even shorter distance between the MTM. But I am too impressed with the dynamics offered by RAAL and since I use active digital XO, I can easily burn the ribbon which requires a fairly easy ribbon replacement. I do not want to burn by dome tweeter though! |
