1、Troels Gravesen 博士的Jenzen Illuminator系列，近期开发了Jenzen Illuminator-5，其单元数量、构架与组成形状Wilson Audio alexandria XLF非常类似，
其文档介绍、元器件选择、分频线路以及测试数据都比较详实，为打造Wilson Audio alexandria XLF奠定了一个很好的基础。
虽然有了信心，但要打造一个Wilson Audio alexandria XLF外形出来，对于我这样完全没有木工经验人来说可谓是难上加难，太多曲线、弧线即使用雕刻机很多局部仍然无法完成。

Troels Gravesen博士关于Jenzen Illuminator-5声音的评价：
“I can't tell you what this Illuminator-5 sounds like. Like food and wine, you'll experience something different from me. Auditive perception is just as subjective as taste and smells.
I've already told this speaker can play seriously loud and deliver a punchy bass, but what surprised me the most was how low it can play. Thanks to the dispersion of the small midrange and the presence it creates, we don't loose grip of the music when listening at low levels. We maintain the ability to catch subtle nuances and tonal colour even when turning down the volume to quite low levels.
I'm sure I'll have the question on a smooth midrange and silky treble. These phrases really mean nothing, but YES! It's got a non-aggressive midrange, all of the midrange. Even with the tweeter tuned to a fairly flat response, you'll listen to treble, not tweeter. We really shouldn't be able to hear the tweeter as such. If we do, it plays too loud. And yes, it does vocals really well too. I've tried all my troublesome vocal recordings and this speaker just doesn't care. One thing that can turn vocals aggressive is beaming of the midrange driver, for full-range drivers this is often heard as the "midrange shout". This phenomenon is effectively eliminated by the small 12MU driver. The 12MU also creates a better placement of vocals and instruments in space than the usual 6+1 set-up. It simply creates a better 3-dimensionality.
I run these speakers from my bi-amping set-up: GlowMaster KT88 for the MmT section and a Hypex digital for the bass module. The Illuminator-5 likes a little more power than my ATS4 speakers, I guess we're talking 1-1? dB reduced sensitivity compared to ATS4, but it's only one click more on my attenuator.
Setting up the speakers in our living room was unproblematic. Same place as ATS4 and a little experimentation on toing-in made it.”
5-way speaker system or you could argue the 22W not having a high-pass filter makes it a 4?-way due to the use of two bass drivers having different low-pass functions.
Bass reflex, closed box and aperiodic tuning is used for lower bass, upper bass and middriver respectively.
Points of crossover; 80, 180, 900 and 2800 Hz, 2nd order LR, mids and tweeter time-aligned.
Impedance: 4 Ohms, minimum 3 Ohms.
Sensitivity: 88 dB/2.8 volts, 1 meter.
Amplifier requirement: Minimum 50 watts.
