Default About active crossover connection issue when trying F.A.S.T

Hi Ladies and Gentlemen. I built an active crossover with military grade parts.I decided to make crossover frequency of 380Hz for my Jbl 21cm bass and 4 inch full range speaker..And i tried it today that it is working or not.When i connect it to my headphones one channel gives deep bass and the other gives treble.As expected..But when i connect it to my lm3875 stereo amp both channels gives bass.I do not know why it happens.Could you tell why it happened.Do you think there will be loop?Thanks in advance

Hi again.
Because of my baby daughter interested in fullrange speaker very much and she always wants to touch it, and also my wife always like slim and long speakers, i decided to build a slim tower.I decided center of fullrange speakers have 90cm height from ground.Crossover frequency is 380hz.Do you think there may be a problem if i put woofer into the side of cabinet? lambda around 89cm.Crossover is linear phase.Sorry i am new at fast projects and also speaker designs.Thanks in advance
