OK. I picked these up today at GW for $12. They need refoams. Since I can't play them until I re-foam them: 1. I was wondering how these little bookshelfs hold up to others of similar size, etc. 2. Any advantage to the graphite composite of the speaker cones vs. paper? 3. Any crossover upgrades that would be worthwhile doing (other than just re-capping)? These are my first set of home audio Infinity speakers which I might use at work once I replace the foams. Thanks.
