I've just gone through the last two sets of pictures (31 in total) and put them in to a better order and written explanation notes for each one - hope that helps.

I would like to use a RAAL tweeter but it's a bit too expensive. Also, I only need the crosover to take place at 1 to 1.5K and I just don't need the low end properties of the RAAL.

So I popped round to Mark's today and took my little camera with me to snap a few pics.

This one shows the finish he's got with his laminate, it's super glossy with the finest diffusion pattern to it. It's not a mirror finish, it's more subtle and softening than that. This shot also really catches the effect from that glass edge acrylic.

This one nicely catches the contrast in materials between his new mid and tweeter surrounds and the laminate, the closed cell foam provides a textural contrast and really makes the ally driver surrounds 'pop'.

Here's the back panel with the crossover panel blanking plate fitted. The camera doesn't quite capture it but these are a perfect fit into the recess.

Here's a real moment of truth shot as Mark peels back the protective wrap for the first time. The tension, and relief was palpable.

A little closer up on the crossover plate, plenty of nice detail here, the finish is impeccable.

Ok, enough with the peel and reveal.

Extracts from the crossover, mid and bass sections laid out. I think these are soem way from being the final parts, some tinkering to do yet.

Close up of the new badges, these are etched on two sides to give a 3D parallax effect. When you look at them dead on you can see only one line of text, as you shift to the side the depth of the panel becomes apparent and the back lettering is revealed.

Nearly the whole shebang.

Close up of the brace, that's a beast, that bass driver isn't going anywhere once that is torqued up.

One last shot of the new badges, this one catches the full depth of the panel.

And that's it for now I'll take soem more once they are finished and back in place. There's still some spraying to be done on the drivers and the edges need a clean.

But bloody hell they do look quite remarkable.

Never really liked the '70s appearance of yams but these are bloody marvellous!

Nitrous or DIYNick depending which forum we are on

Thank you - I'm not a fan of the 70's look either.

I will have a day of soldering tomorrow and get the insides of the external crossovers built (the cases are already complete), wire up the insides and make the umbilical cables that join the external crossovers to the speakers. I'm just waiting on some resistors I ordered to replace the L-pads. Then all I have to do is reinstate the internal wadding, solder up the drive units and bolt them in to place (tighten up the bass driver brace).
