Active XO...so first active XO cuts the signal to hig mid and low ...and then passed the signal to amp and then to speaker...

passive crossover means you get whatever cross range of sound circuit is set at on the crossover.
active crossover means you just have a variable resistor and caps adjust the cross over point between the mid and twitter.
Like i told you different peeps like their sounds at different crossover points, because it sounds different.
Also depending on the tranducers some perform better at certain frequency crossovers.
so if you build an active crossover, you have the liberty adjust to the way the system sounds. by changing what frequency ranges are fed to the different tranducers taking advantage of the tranducers for its optimum performance capacity.
When you do sound seperation before amp, is called preamp.
when you do preamping, then any small change you apply to sound will be big change after amplification.
Normally this way the sound is very unlikely to be close to the actual recorded.
In fact you changing the sound.
Whereas when we do speaker crossovers, no change is done to sound before amplification.
after amplification the amplified sound is fed to the differnt tranducers only because to maximise the transducers performance.
necause twitters are most efficient for pitch sounds and....... and......
so the reproduced music is 100% true to the recording. Only that the efficientcy of the different transducers enchance the sound seperation for making the sweet spot. When you listen to music in a sweetspot setting. before you will a stage opens, with placement of the different instruments, so setting become close to life performance.
absolutely uncompressed. When you listen to normal sound system is just a ball of sound. In aldiophile settings, there is placement of instruments, stage and presence. In fact on good audiophile recodings you can actually feel the performer there in person, when you close your eyes.regards
i worry now for your twitters. because you fed full range of the frquencies to the twitters. i would believe the spiders holding the twitters cone would had been damaged by the low sound waves. because at 10hz and below, the wave are actually about 40+ feet between break point to break point. Which means is very likely the twitters spiders had over stretched. Twitters are built for small waves and high frquency of movements. so for 12khs sound it vibrates at 12000 pluses. if fed a 40 foot wave is likely the cone overstretched.
This is why when you playing music, you can see your woffers/subwoffers pump air, because they very large wave. Whereas if you look at the twitter you not see any movement, because they doing small up to 20000+ wave vibrations per second.
just a little work.
i love watch manipulators die.
Thank God i may not need stick around too long watch this fiasco.
