re: CS-99

These speakers have one problem that the CS-99a's don't have, and that's foam rot, but thankfully it's just the tweeters that have this problem, and the repair cost is very minimal. The front grills are not meant to be detectable, so take care when removing them, but if you do own these speakers there is a 100% chance the tweeters need to be re-foamed, and it is well worth the time and effort it takes to get them fixed.
