实在不敢赞同。
ATC 50的频响是我从ATC给我的资料中照抄的,是80Hz—12KHz,+-2db,
SCM20的低频延 ...

这是ATC官方网站对SCM20的概述。文中也提到了中低频如何,如果SCM20没有这个能力,它是不敢这么登出来的,而且没几个厂家敢这样描述其厂品。红字部分是特意加上的,这两段话清楚的解释了ATC为什么高音会暗和为什么大功率放大器推不好它原因
SCM20SL
AN OVERVIEW
The hybrid design incorporates a 150mm bass cone on to which is grafted a 75mm soft dome.
The magnet assembly utilises ATC's unique "SL" technology which greatly reduces distortion in moving coil drive units by a very significant 12-15dB (3rd harmonic). To minimise Time Domain Distortion both dome and cone are made from acoustically "dead" polyester wave material doped with ATC's own formulation.
Not only does the SCM20 reproduce bass with remarkable articulation and authority, it also has outstanding mid-band clarity, incredible dynamic range, and awesome power handling.
The active version is powered by the ATC "Grounded Source" Biamplifier. The bass/mid is driven with 250 watts, while the tweeter has 50 watts of class "A" power.
Both amplifiers feature momentary gain reduction circuitry which both protects drive units and prevents unpleasant sounds from overdrive.
Accompanied by either ATC SCA2 or CA2 preamp the SCM20AT will out perform any other combination in its price range any many costing far more.
An all time classic still available and in any veneer to special order.
