I had a pair of Lowther DX4 drivers and their foam deteriorated. I looked around at replacement foam for the surround and spider and found Zenwoodaudio sells repair parts. I purchased the repair parts from him and after the repair, I thought that the drivers sounded even better than the original, although this is impossible to confirm without A/B testing. I don't know if the parts would work with AER drivers, but it would be worth looking into.
Zenwoodaudio has a youtube video showing how to make the repair, and it is very doable for a first time speaker repair.
A tragic story, but I was trying out different diffusers and a homemade rubber washer got twisted and blew out the former of one of my DX4 drivers - yikes!
So I purchased DX65 Lowther cones for replacements, and this has worked out really well for me. I use the DX65s in front waveguides.
I find the 15 ohm variety of Lowther drivers to have fewer issues in the treble. I ordered the 15 ohm, DX65 drivers with straight whizzer cones - based on a modification suggested by a long time Lowther user, in which I cut the end of the rolled edge of the DX4 whizzer cone and unfolded the whizzer - and found the high frequencies to be better.
Last comment, it is worth trying out different diffuser shapes with these wide range drivers - I have the Lowther bullet, holey doorknob and light bulb diffusers, but in my homemade waveguides, I found the Par light bulbs to work the best - the light bulb is the plastic variety with rounded edges and diffuser essentially covers the entire face of the cone, not the surround. If you want to see a different version of what I use, see the Beauhorn Virtuoso website for their diffuser.
