OK Gents.

May this be the best one ever.

Posts about the new meeting for the coming year can be made here.

Be there or be square ( Oh do you have to be old enough to know what that means!)


I spoke at length with Pierre right after the last get together and we agreed on a few ideas to maybe make the event even better.

Will bring white boards and flow charts (not) to the lunch (but will table ideas)
Nice to see more members calling in.

There are many more that have not given their availability.

Everyone that knows a friend or member of the DIY community might do well to get out the call to arms.

Lets make this one one of the best.

That means we need as many people as possible.

You need not be building or bringing anything.

You need an interest in audio. We have a great core of people that have things both new and old that sound awesome.

If I am around I will be bringing some interesting toys.

As for horns.

There is a set of back loaded horns that will be coming.

And most likely a set of two way coaxial front loaded horns that will be coming.

Might cobble together another front loaded horn subwoofer to!

We haven't shook up the place for a year or so....
Looking forward to it Mark. I picked up a ClassD Audio 4 channel with 300 watts RMS per channel. I'm likin' it very much.

Have you got the horns veneered or are they "project level" still?


The horns are a triple set.

And are to be painted flat black.

There is a second set that will be veneered.

I'll bring the ClassD along for sure.

It's only about 25 pounds which is a lot more than the T-amps but sure isn't what other classes of amp would be to move around. Like the Emotiva 7 channel. 100 pounds.

I'm currently building a Hypex NC400 stereo amp and the smps makes it a fly weight, so I know what you mean. If I have it done, I'll bring that along too.

But I'm not as ambitious as Mark, it may be ready in '17 :)
