Questions about dimensions on 604B and 604G horns....

**oface1** · December 23rd, 2019, 12:15 AM

Would anyone happen to have the following dimensions for these horns? I tried looking it up, but can't really find anything substantial.

I am wanting to make some wooden ones for myself for a my pair of duplex's.

Here's the dims I need:

1) Inside of the mouth for one of the cells.

2) Inside of the throat for one of the cells.

3) Total length of one of the cells,down the center axis.

Thanks!

Oface, I have a horn off of a 603. I'm pretty sure it's the same horn with just a different mounting system. The horn throat for one cell starts at 9/16's length is 3 and 3/16's, mouth opening is 1 and 15/16'. All in inches. If you also need the G horn I have one of those.

Louder, you are awesome! If you could share the dims for the G I would be very grateful for that too!

Merry Christmas to you and yours!

Thanks again,

Chris

Sorry it took me so long to get back. The holidays ! The throat is 15/16's hoz and 5/8's vert. Mouth is 1 and 7/8's horz and 1 and a quarter vert. Throat length is 2 and a quarter. All in inches. Remember your dealing with two different mounting systems with the two horns.

Oface, I always wanted to adapt the 931-12 horn to my 605's. Seems like a much simpler build and is a better match to the 604 throat being 60 x40. And if you have to make the mouth shorter it already made all the moves.

Hey louder, thank you for the information.

Happy Holidays to you to as well!

I do not know which way I am going to go. right now I am in the midst of packing up all my gear and household belongings and getting ready to close on my new house, so it has been a hectic holiday season for me and my family! I am looking forward to the new place, especially since it has a dedicated room for music/ht!

Later!

Great to hear. Hope everything goes smooth. I tore down a load-bearing wall so I could end up with a 13x23 livingroom.

Those are fun! Not.

What's holding up the roof up now? I just added some triangulation and still holding strong almost 43 yrs now.

I remember two two by tens or twelves with 3/4 inch plywood in between them. We started @ 4:05 and finished @ 5:55. (First drinks poured). And there's a 4x4 at each end holding everything up. What was really cool was watching the retired carpenter set everything up. Every other two x four was twisted in place at a ninety and they took every other one out. And no problems since, if you don't the quad 18's cracking the window !
