Ouch! $100.00 for brass mounting hardware

[planet10]

They sure are purty... some of those on my FE103As would sure be nice (i was going to make some wooden ones). If you decide you'd like to try a run for sale, i'd be interested.

What size would you require?

 

[planet10]

What size would you require?

The inside of the voice coil is 20 mm, so with some clearance 18-19 mm diameter, and the top of the voice coil to the edge of the cone is 25mm so that would define a maximum length.

Looking nice!

Dumb question - are phase plugs hollow, or are they stationary? Hopefully, I can fire up my seas Thor this weekend and find out myself 😀

The rod I have is 5/8" I can make any length you like.


jgwinner

These are solid copper and stationary. Which is good because they are really heavy.

Ah! That's what I'd been thinking - I first typed "how did you ever get them light enough ... " then I figured they were stationary ...

By the way, the speakers look really nice. Can't wait to hear what they sound like.

On the mounting of the tweeters, it looks like they are a bit 'inside' as they are on the backside of the oak - will you have some difraction effects, or will the routed hole act as a very very small horn?

That is a little less than 16mm, probably not close enuff to make it worth you going thru a storm of copper... 😀 Thanx vry much for the offer thou.

On the ones we are using we mount them from behind with a conical waveguide. Helps them go down a bit further and match the dispersion of the midbasses closer at the XO.

That's one nice pair of speakers!

 

[tom1356]

Thanks for all the kind words everyone.

I took Jim Griffin's advice and rounded over the inner baffle.

 

[tom1356]

Not done by a long way but this is an idea of the final right base section.

 

[tom1356]

I took Variac's advice and thinned the baffle edges as much as possible without a shaper. Thanks Dave!

The top still needs to be shaped and installed, the phase plugs need to be put in, the base needs to be asembled, and all the adjustments still need to be done.

Wow, that's an excellent idea, and I've already glued my front on my speakers 🙁

Looking good ...

 

[tom1356]

Ooops! I forgot to thank Mark (Variac) for his help so far.

Do you have any pictures?

 

[jgwinner]

Not yet, my Thor's still look pretty rude. I've been out of town, but I should be able to post something in a couple of weeks.

I'm also putting off attaching the bottom of the speakers; I want a solid seal (glue) but keep thinking I'll need to fiddle with the stuffing (screws and gasket). I can get to it through the speaker cut outs though so I'm just going to glue.

With the help of the mirror tool in PStudio.

WOW!

i need work to slow down, and for my amps to be done so i can start working on the rest of my system!
