?Brightening? up a pair of RT15?s

Greetings!
I have a pair of RT15 bookshelf speakers I bought new back in 1998 to go along with the RT400?s and matching center I also bought. They have very little use over the years and spent most of their life in storage.
Now they are being used as back surrounds in my 7ch system and I would like to brighten them up a bit since they are rather flat sounding. I did run them for a couple hundred hours as PC speakers playing various music and such which didn?t help.
I took the crossover out of one speaker and it is rather simple. I?ve read a just about everything on here about upgrading the caps and resistors. Not looking to spend a ton on these as it?s more of an experiment to see what happens. Dayton, or standard Jentzen caps would be fine in my book for this and I don?t mind swapping resistors either. I figure $20 or so per speaker is a reasonable price even if I used Mills resistors.
One question I have is there seems to be two resistors. The typical 5W, 1ohm, 5% resistor. The other came out as a wire-wound resistor, 100ohms, 65wv, 5% when searching the part number ?22J100? on it. I?m not sure if it?s an actual resistor or just a bypass cap. If it is a resistor, what would you suggest swapping it with or if is not even worth worrying about. The cap is 5.8mf and the closest I could find was 5.6mf but if I understand correctly it?s close enough not to matter too much.
I?m currently running RTi-A?s for my LCR, and swapping out the RT15?s for a pair of RTi-A1?s would be nice but I have an expense hanging out there waiting (house wise) on permit approval which is much more important than a new pair of speakers at the moment.
Thanks in advance for any input.

The component is a .22uf bypass capacitor. Sonicraft makes both 5.8uf and 6uf capacitors that are still on sale.

They are still running their 20% off sale so with the capacitor and a Mills resistor you are still within your budget for this upgrade. Better act fast on the sale though.
