It seemed to me that the weakness of the 3.5’s might be due to the paper surrounds of the midrange drivers. The woofers seemed sturdy enough.

Thanks to those who posted the earlier advice on the amp. I took a chance on the used Nova 300 and hopefully it’ll work out well.

I had another question if anyone has any experience with basic speaker repairs. The surround on the midrange driver on my 2.4 appears to be coming loose from the cone, and causes an awful rattling sound at certain frequencies, esp acoustic songs.

I was hoping to glue it back on with some sort of rubber cement or flexible adhesive like E6000. Any advice on what to use and how? Image of driver:

Excellent! keep me posted as you massage the Nova 300 into your room/system.

Stay tuned until 1 of the Panel members chimes in about repairing Midrange surround.

Happy Listening!

unsound - that self-surround does break down over time. At the time we were trying to minimize the standing wave reflections and non-linearities between the cone and surround as well as ultraviolet deterioration of soft plastics. It worked well when new, and held up pretty well. Natural rubber turned out better.

Those woofers are bomb-proof, rarely fail in use.
