求教古董全频的品牌、型号和玩法

空灵派

fostex的喇叭用石机推还好点，这个f200a就算用胆机推起码也要三、四十瓦（甲乙类）。

请问哪里能买到？西子喇叭花是新的吧？它和lowther 相比呢？
哦，现在在淘宝上看到了，就是不知道声音 ...

我聴過，聲音比lowther厚實很多，以一萬多連箱的售價，只能說非常超值，如果要再上一歩，就要拿多四萬買法國的SUPRAVOX賽博威聲215鈷磁

fostex的声音紧、薄、干、硬，和日本大部分的音响器材一样，因为偏重于测试指标而不太相信耳朵的主观调校，所以作为家用都不太耐听，要搞好要在音源和功放上花很多功夫和投入

日本的全颜如果说经典耐听的就几样：中古的三菱大通P610系列（犹其是纪念版真皮悬边的），珊瑚系列，新晋品牌手工制作的飞丝翠系列

一万八千，还是泡沫边，那不是可以买lowther了

最便宜的那款捞打不行的，别碰。

如果全频喇叭需要超过7瓦以上的真空管黄金功率（单端甲类）才推得动的，建议还是不要玩了浪费时间，不如直接玩同轴大口径喇叭和高灵敏度号角音箱更全面更有意思

The Fostex F200A drivers are the best sounding of the Fostex “single” drivers with killer bass, rich detailed midrange and no “shout”. The only thing they lack is the very top end and need help from a super tweeter. The Hi-Vi RT2-Pro ribbon tweeters are a great match to fill out the top end for the F200A. I have a pair of KCS speakers that use these two drivers in a large ported cabinet (see the pic) and they are fabulous sounding. They need about 4 watts or more of power to get them cooking in a moderate size room. I have used a 300B amp with these in a large room and a 45 amp in a small room.

I acquired a complete set of drivers and associated hardware to build another pair of these speakers. All these parts came from a pair of KCS speakers whose cabinets were trashed by UPS. All of the components escaped harm and are in perfect condition. I have downsized to a much smaller home, and I am not going to be able to build another set of these, so I am passing the parts along. Here is the list:

A pair of Fostex F200A drivers

A pair of Hi-Vi RT2-Pro Ribbon Tweeters

Mundorf Supreme caps and resistors, all wired up for the crossovers

Gold binding posts in biwire cups

The price on all these parts new was over $1,600. I am asking $800 plus shipping. The shipping weight will be about 30 lbs, from zip 92078.

These KCS cabinets are large volume ported with dimensions of 13” W X 17” D X 40” H.

Here are some specs on the drivers:

Fostex F200A 8" Full Range with Alnico Magnet •        Frequency response from 30Hz to 20kHz •        90 dB sensitivity •        Znom 8 ohm •        Re 7.3 ohm •        Le@1kHz - mH •        fs 30 Hz • Sensitivity 1W / 1m 90 dB

Hi-Vi RT2-Pro Isodynamic Tweeter, 220mm x 166mm, 99dB Frequency range 2.3k to 35kHz Nominal Impedance (Z)(Ω) :        8 Nominal Power Handling (Pnom)(W) :        30 Sensitivity (2.83v/1m)(dB) :        99 Weight (M)(Kg) :        1.06 Magnet System :        Neodymium Recommended Crossover Frequency(Hz) :        >2300Hz

全频也有大口径

在初烧家里教他调校过，胆艺轩基本没人玩这个，犹其是老烧。fostex参数看起来也很容易推，但实际上要几十瓦的胆机和上百瓦的石机推时，高中频与低频才能衔接平衡，有机会自己亲身去玩一下才会有切身体会

听起来好厉害的样子哦

而且还有个麻烦就是用大功率放大器推动fostex全频后，号称刮20KHz平直的高频严重缩水，表现往往还比不上那些标称只有16KHz左右的古董全频，就更不用说和劳达比了
