The midrange opening was to wide , so a piece of carbon fibre was used with the appropriate circle cut into . Cutting a circle in cf is bloody hard .
.

Contact glue sealed the carbon fibre in place , the driver isn't heavy and dome midranges have low velocity moving mass so it should be enough to hold it in place .


When the cabinets are complete , I am going to nick an idea from Sonus Faber and cover the baffle in faux leather .

Today , im feeling rather foolish . A capacitor discharge tool as arrived and I'm wondering why I haven't had one sooner . It would have saved a fortune in blown boards .

I console myself with the fact I've had a major brain injury and a survival rate of 20% makes me lucky beyond belief

I used to use an old bedside lamp with 60W bulb in it and crocodile clips on the end of the live and neutral wires.

That's a good idea , I wonder why Google didn't suggest it ?

They don’t get commission on no cost solutions?

Capacitor discharge tool? What do you think your tongue and your fillings are for?!

Despite Linydsey's recommendation , I resisted the temptation to use my tongue ( it's 45 volts ) but the tool did as advertised though it took longer than 3 seconds and I successfully fitted the fm300a boards .

Quick listen and oh there so much detail . BBC recordings of genesis , mama ,you can hear the crowd clearly . Better definition and separation .

It's been some time but my memory was not playing tricks

I watched a you tube factory tour of bowers and Wilkins


The way they made cabinets was interesting , if beyond the means of the humble 1armed diyer . What was interesting was the way they strengthened the baffle with a metal insert .

Strengthening the baffle was not something Id considered ,

Have u dabbled with open baffle yet- it’s another interesting rabbit hole
