As the pic in Grindstone's post alludes to, the ST350 was meant to be used with a passive EQ circuit following the X36, to compensate for the falling high freq. response of the CD horn. The ST350B EDS shows a 7.5 Ohm resistor in series with an 0.18 mH inductor shunting the plus to minus, followed by a 2.5 to 3 uF cap in series with the ST350 plus terminal. Without this (or something like it) the ST350 will sound very shouty. You don't mention whether your DIY XO incorporates an EQ circuit like this or not. I would try the stock 3500 Hz XO freq. along with this EQ circuit, while adjusting the cap value. Your choice of a 4700 Hz XO point may have somewhat of a similar effect. Just my take on it.
