I picked up a pair of stock crs+ and am thinking about upgrading them. Would it be possible to add just one cap in the high pass with a value of 17.7 uf rather than one 12uf and another in parallel at 5.7uf to do the tl mod? Thanks

No you cannot. The 5.8uf (not 5.7uf), is shunting the Resistor, and modifying the overall frequency response of the Tweeter.I picked up a pair of stock crs+ and am thinking about upgrading them.

You can't just throw in a larger cap and expect it to perform the same. The TL modification were designed by Polk, and tested extensively by many members here.Home Theater/2 Channel:

I did an extensive CRS+ overhaul in 2012 and did a write up here:

Good luck with your project, keep us posted.Good music, a good source, and good power can make SDA's sing. Tubes make them dance.
