Well on Saturday, my soldering iron crapped out and I actually found the sticker of my frustrating roll of solder on the floor!!!!!!
It says "Plumbing Solder".............


So, bought new 30/60 switchable iron and ELECTRICAL solder. Jeez what a difference - so easy.

Proceeded to test & solder, test & solder etc. etc. and hey presto, sound at last. Yaaaahhhhhh.

No "Hi-Fi" stereo amp or anysuch though; just plugged into my Ampeg & let rip. It's quite trebley.
Pics attached.
I took a couple of video's of the cab in full flight but don't yet know how to upload them. They're largish files but surpisingly good fidelity for a Samsung fone.
Someone on here in the past said that you can hear each band as a separate feed - I can absolutely vouch for that!

The treble via tweet is omnipresent but the L-Pad tones that down; almost.
Actually I find the tweeter adds a width & detail of colouration that mids can't reproduce. Lovely icing on the cake really.
Mids are great.
Woofer there but as the back is still off, that will come later. I can hear the possibilites.

I've installed an old grill that I had as protection of the woofer until such time as I get the full screen made.
I found a free on-line tone generator as recommended and put some serious low frequencies through her at voltage - it's amazing that I can actually hear much lower frequencies than I thought I would be able to.

Anyway, I'm happy and moving on with closing her up and testing tone and pressures etc.
More to come no doubt.
Thank Bill for your efforts, plans, kindness & studious encouragement and to everyone else around the BfM world for their concern, support and information.
Cheers All
