Apogee diva cone driver conversion
Hi All,

I require some assistance with line array cone drivers to match the Apogee diva midrange and tweeter. I have one good bass panel and one that needs to replaced due to the fact that there is no installer in South Africa it would be very costly to send to Auz and then back to SA. I will have to wait until such time there is a local installer to repair the other bass panel.

For now I have to go with what I have which is 4 x HiVi D6.8 7 drivers and 4 x 9 Morel Drivers my plan is to go line array 4 per side morels on the top and bottom & HiVi in the middle. I am considering doing open baffle as opposed to sealed vented boxes. Should go more like a Genises Can anybody offer some input?

Remove the bass ribbons and mount your drivers directly into that area? Your plan seems workable to me.
You will probably require some electronic EQ once you have the drivers installed and the response characterised.

My plan with my Duetta II's is much the same. In fact, I'm already started on the project. :)

This should be a considered repair procedure for all Apogee's in the future since the "factory" bass ribbon replacement is horrendously expensive and the logistics extensive.

Hi Dave, what make and model of drivers are you going to be using? If you can share some project details it would be appreciated. I'm lookibg at buyer a behringer DCX 2496 active cross to get the high pass to match the lower end. Cheers Brian

I'm going to use 7" drivers.....six per side. I'm not going to use high-dollar drivers in order to keep the cost down. Most likely an excellent driver the like the Seas CA18RLY will be what I choose.

Hi Dave,

Have you made any progress on this project of yours? My Cal Sigs are still doing fine but I wouldn't mind keeping this mod on deck for when that time comes.

I had to table the project for a while.....other items higher priority on the audio to-do list. :)

I have since added MGIIIA bass panels with my apogee diva midrange and tweeter panel and all I can say is wow it really works well together. The crossover was a little tricky but I eventually got it. I listened to some ML Summit x this week I honestly felt my combo beat it easy but its always subjective. Im driving them with a Yamaha MX-D1 Class D Power amp.

I have always wanted to hear that yammie class d amp. I use an Icepower 1000asp on my Apogees and works very well...

Hey John, This is a great amp very warm with great control and lots of detail. I wouldnt change it for anything!
