Dave,
Put me down for another pair.
That's a nice thought Peter. Don't be so sure about the PCBs, though. The crossover can be done point-to-point and arranged pretty much just like the schematic, which would make it easy to point out the basic purpose of the schematic to a kid. You could also play with heatshrink, which is kinda fun.(although a run of those PCBs would GREATLY help my cause...
That's weird...the truncated version of the tweeter (DC28FT-8) has slightly different specs. The curves are identical and more closely reflect the DC28F-8 numbers.
I don't think it's enough to matter since the Re, Le and Z are the same.
...........fs..Qms..Qes..Qts
DC28F-8....637 0.82 0.90 0.43
DC28FT-8...596 0.86 0.60 0.35
There was the original build here which would be the 08-09 stuff and then the all the "locals" who wanted a pair had one. Then last winter the project was published in PE's Project Showcase and there was a resurgence.
Dave,
Put me down for another pair.
I'm highly tempted as well.
Any chance that there could be another run of Zilch's PCBs to go along with a group buy, too?
I would be interested in a group buy.
Me too!
me too! I already built a pair with my son (who's now 8 but at the time I think he was six). I know this sounds crazy but it's the way I think:
I've been toying around with the idea of doing my own 'group buy', but haven't put much thought into this. But my idea is to collect 4 or 5 dads and their 8 year old sons and do a group build in my garage in spring time. I've already mentioned it and a all the dads I ask are "in". Sort of like an after school program with benefits. I'd prefab some mdf into parts so the kids and dads would just assemble the six pcs and spray paint them in one after school session. Then in another session we'd solder up the crossovers. And maybe the third session (if needed) we'd assemble the speakers and let them play some music. At the end of these three sessions the kids (or their dads) would have a fantastic sounding pair of speakers and a memory to last as long as the speakers do.
So I'm thinking you might even include me for 4 or 5 sets of components on my own...
let's do this! (although a run of those PCBs would GREATLY help my cause... Zilch, add me to the miss you list- hope there's music up there wherever you are!)
take care
peter
RayW: what are you currently driving your pair with?
