Interesting - those look like film caps, and might not need replacing. Certainly they don't need replacing at 90 bucks - you can spend very large sums of money on fancy caps and coils, but some sense of proportion is called for. It doesn't make sense to spend more on crossover components than the speaker is (or was) worth. The HEDs were not subtle speakers - they weren't meant to be. So fine shades of difference in caps are unlikely to actually be audible. Meanwhile, you could have spent the money on things that might actually make more of a difference to you. Remember the old joke: I spent most of my money on women and cars - the rest I wasted.
