Finally got a chance to work on these speakers again. I made a new frame for the speaker fabric. I was able to re-use the old fabric as it had not shrunk too much.
The picture below shows the frame under the covering because of the camera flash but it is not visible otherwise.
There is one final issue. one of the speakers has a problem with the "Fried egg" tweeters, they do not work unless pressure is applied to a specific point on their rims. I have them temporarily working with a pair of magnets. I will have to replace all of them at some point.
How do they sound? Great but, Very BASSY. Treble needs to be bumped a bit to compensate. I tested them with different records and CD's. They really like orchestral music. But sound good with Rock. They did not work well with my Beat Dominator CD. The bass was just a little too low for the crossovers. If I kept the volume at a reasonable level they could handle it, but turn it up too much and they cut out.
