Duetta Sigs

Postby Al^ on Thu Apr 05, 2018 3:30 am

Hi, I had my stands off my Duetta sigs for a while and I miss placed the 8 screws that secure them to the speaker, like to find out thread size and length. Thanks Al

Hey Al,
I don't think thread size really matters. The screws go into the wood panel and not into any type of metal thread hole. as long as they go in about 1/2" into the wood and are snug, you should be fine. There is nothing in the screw areas other than the wooden frame so you don't have to worry about damaging anything inside.
Good listening,
Z

Hi Z,

I'm pretty shure you are wrong here. The Duetta Sig is different from the I and II in this respect.
The feet are attached with threaded bolts, not wood screws.

And at least one pair of these bolts is behind the tuning clamp of the bass ribbons, so if you use bolts that are too long, you may well ruin the bass ribbon.

I'm not shure of the bolt size, but I think it's a 3/16" UNF, the necessary length is easily checked: just insert a thin rod into the hole, and see how deep it can go before you feel any resistance. You should be ale to find the depth of the metal insert, as well as the total hole depth quite easily.
Use a bolt that is about 1/8" shorter than this, and you should be fine.

Henk

You could be right Henk. It's been a while since I had the Duettas, and I realize they are not wood screws, but they do go into the wood and not into a metal thread. Not sure why Apogee did it this way. Bolt screws into wooden holes.

It's been a few years since I last opened mine, but I'm pretty sure that there are t-nuts that the bolts go into, not just into wood (which would never hold).

The bolts are 10/24UNF x 1". Make sure you don't use longer ones! :D

Thanks for the info, Has anyone made stands for these that go right up the back side, one on an angle and one straight up. if so did it make much of a difference sound wise, or just be a waste of time?
Thanks Al

I made stands for my Diva's and it made a huge difference.
Couldn't figure out how to attach an image to show you, but they made of are 1x2 inch aluminum bars that add a great deal of stability.

Zardoz, Could you send me a pic of the Diva'a you did to my email. aawirth@sasktel.net . Did you use solid ali or tube? I may do that to my Diva's as well.
Thanks Al

Hi Al,
I'll take a picture and email it to you. I know I have one on my computer somewhere, but can't seem to find it right now. I used solid bars for mine, with each of the 3 pieces welded together, no bolt joints. They are fairly heavy and rigid.
