More stuff

Wadding, cable and connectors arrived today :)

Neutrik (pricey!) Speakon 4-pole plugs & sockets, 8m 4x2.5mm cable and 2 packs of MDM-4 wadding 

When I opened the packet I thought maybe I should have ordered the screw terminated chassis connector, but that isn't airtight - choices!! The connectors use 3/16" push-on spade connectors, and I've just tested the ones I have - great fit! Far easier than soldering, and airtight means I could amount them on the woofer tube if I wanted to. The cable is pretty cool, if a bit chunky, good job it's 4-in-1. 

Actually, when I reviewed the NL4MP sockets and found the ST version, I also noticed that a 10m 4x2.5mm cable with "Neutrik-alike" Speakloc plugs was only £20. I could have bought one and cut it in half - the Sony amp takes bare wires anyway - would have saved myself £15 and had an extra 2m of wire... 

Only the bolts to come now, I'll have to actually do something soon. Maybe just make the cables up :-), a nice way to pass the darkening afternoon. After all, this morning I got the old freezer out into the garden making rom for the shiny new one on Friday, and got all the decorations down from the loft, and spent an hour teaching kids to programme rolling background games in Scratch at the Code Club. I deserve this... 

Wickes-style Fernco 4" clay to PVC connectors, made by FlexSeal, a Fernco company 

Popped around to Wickes and lashed out on the rubber connectors. I've tried them on the woofer pipe and hurray - they fit really well, so I'll be going with these. Need a bit of a cleanup but hey, no problem.

2.5mm wire capable 3/16" and 1/8" tag connectors for Speakon-speaker wires

On the way to Wickes I dropped into The Shop On The Bridge and acquired these connectors for Speakon to speaker wires, with 2.5mm capacity and the right tag sizes. Except I screwed up and didn't get all fully insulated, might exchange four of them tomorrow, the four blue with uninsulated connections. Otherwise the connections on the socket are a bit close. I guess if the -ve ones aren't insulated it won't matter.

The connector colours refer to the wire sizes they fit, rather than an polarity indication - you'll have to look at the wire colours if you want to see what's happening, guys! Strangely the little red ones are HUGE for wire, rather than 1.5mm as the colour would indicate, even the SOTB man was surprised.
