Sometimes budget dictates "if you're going to do it, do it as well as possible".
At the time I redid my 11T's, the Jantzens were a gift and I had spent the rest of what I could afford on soldering equipment and all of the other components. It was the best I could do, and all I want the OP to know is, even with cheaping out on the low caps, the difference in sound is still remarkable. It will still be a different set of speakers all together than what you hear now. But, I still plan on getting a better, and proper, cap in there.
That being said, F1nut's point is rock solid in another fashion. I have a set of Infinity RSb's I scrimped on to begin with, and they didn't sound as good as I know they can. Now, I am re-spending more money re-purchasing crossover parts, new boards, etc. And it is taking me longer to put the money together.
Sometimes it's a fine balance between available cash, the best thing possible, and wanting things done now. At least for me it is.
