Why wont speakers show up in the 3D box?

Why wont speakers show up in the 3D box anymore? Ive tried changing my measurements and speaker size.

I've not updated the WEB since April or May. Maybe you forgot something specify?

Actually its the 2 speaker models I had chosen that dont work. The 15 inch Kicker CVR and the 15 inch Fi BL are both not working

There isn't specified dimensions if you meant that speaker. Just put the speaker cut out diameter and depth

If you specify all dimensions of the speaker manually in your project at box/speaker additional, it will show up. It works for me.
