maha88 - The caps in the Alon 1's are Solen which are pretty good. I would look more to replacing the sand cast resistors. I asked Carl if upgrading the Kimber cap in my Alon Lotus SE mk ll tweeter x-overs to a Mundorf SGO and he advised against it as it would shift the balance of the speakers. He did however recommend changing out all the Mundorf MKP caps to the Mundorf MCap Supreme SO in my Nola Viper 1A speakers and to use a MCap SGO in the tweeter circuit which worked out extremely well.
