Drivers for DIY Heartsfield

[John W]

No problem Nick,

I saw others on the web using D130's with good success (or so they say) so I would imagine that the 130A would be a step up from that.

The last hurtle, from a driver standpoint, is to find some horns and lenses that are not ridiculously expensive!

Any one want a nice guitar as a trade??

This add has been up for a long time on Craigslist in Seattle:

I've contacted the seller in the past about his horns, but don't recall the price. It was too high at the time.
I do remember he is a bass player, and was looking for trades.
If you can work something out, I can help getting them shipped.

Just contacted the seller. Hopefully he has two of those lens assemblies!

Thanks for the link! It is much appreciated

Those Craigslist lenses are probably McCaully devices.

Might want to get measurements to compare to a JBL product and see if they are plastic or made of metal.

So Im making notes and adding small edits to my blueprints for the Hartsfields.
I know during the last years of production it was turned into a 3 way system.

Any suggestions on 075 tweeter placement?

I have seen them placed behind the grills on the top left or right corner of the speakers. This is based on one photo I found on google with the grills removed.
I was thinking of making a cutout in the grill to fit the barrel of the 075 tweeter through so it is visible once the grill is on.

Was this the standard position or is there a better spot to place it?
I have done a little reading where it is suggested that placing the tweeter off center improves diffraction properties.
