1、木工场制作原木箱体（手工制作燕尾榫拼接，非常费工时的活）

2、准备了两套分频器（一套是自制的，根结点搭棚焊接，不用一根导线，另一套是佳讯JX-22c顶级分频器，-18DB衰减，七芯空心电感制作，极显华丽配置）

3、后背包式外置分频器箱体结构，方便对分便器的A、B对换

4、喇叭单体安装完成后的正面视图

5、试听时暂时放置分频器于顶部

6、试听环境（Listen room and system !),和一对惠普的唯真一号进行AB对比

总体自评
用该单元组合制作音箱在国外网站也多有介绍、尤其是在欧洲、俄罗斯较多，有兴趣可  网上搜索一下

老外如此评测
   Not many speakers can handle heavy duty work  in studios. PCA M6 is designed for it!  Used in a home audio setup, you will hear what has been going on at the producers mind
Recommended amp:  50-175W RMS 8 Ohm
Dynamic response:  40-30.000 Hz
Nominal impedance  8 Ohm
Net. weight kg 7,5 kg
W * H * D cm 21 x 37 x 25 cm
Euro incl. vat ex. freight 589,00 a pair
DKK incl. vat ex. freight 4.395,00 a pair
   With a sensitivity of 88 dB and nice impedance response M6 can easily be powered by a tube amplifier and still provide great sound and power. As a tool in a recording session, you will easily feel in control of all details and track layers recorded. In combination with the slightly rough look, it signals "quality kept simple" - and that is exactly what PCA stands for. Use this in your home and you will hear what have been on the minds of the performing artist instead of limit the judgement to "this recording is good" or "that recording is bad". 2 way high-end speakers with this type of technology often cost 4-5 times the M6 price - but of cause; You have to assemble it yourself:)
   M6 can Reproduce as the music recorded. This speaker can be used equally well as monitor as home audio high definition speaker.
   M6 do is very dry and quick in the bass area. Easy to hear all details also in the lower region. This makes it perfect as a semi pro tool
   M6 is easy to run by almost any amp. Good sensitivity and the quick response makes it a perfect partner along with even big subwoofers

   Measurement & comments:
   Measure like a true monitor sound - the discreet level increase between 400-2KHz where all details are revealed. The crossover point around 2400 Hz is done without any visible phase problems to the response curve. Together with a PCA S12 subwoofer, this speaker becomes truly BIG in sound!

   制成的音箱灵敏度约为88db ，对功放要求并不高，普通固态功放（50W*2，RMS）或胆机（20W*2、RMS）足以推动，我听音的第一感受是声场开阔、声音干净、清晰，且在低音量下也保持了很好的分析力（归结为结实的原木箱体大幅减低了声染色和低音单元high definition 所致！)，和其AB对比的唯真一号是惠普公司几经改良、屡获好评的经典书架箱，但在低频力度和清晰度上明显占下风，不如自制箱干净利落、充满质感（人声、弦乐、室内乐、......）。笔者也在不同场合听过B&W801、B&W805这些顶级Hi-End箱，和这些Hi-End箱比较，自制箱似乎还缺少些漂亮的韵味，不过我已经很满足了，毕竟对DIY音响的热情只是出于对音乐的热爱，器材上不想再折腾了，好好享受音乐给我们带来的欢愉吧！
