I would like to know if i can turn active speakers into passive speakers?

Yes. If the speaker employs an active crossover through bi-amplification it can be slightly more complicated as it may be optimized for those drivers and most likely does not adhere to a simple first, second or third order alignment. Many active speakers utilize internal nonadjustable equalizers integrated into the gain circuitry along with the high and low filter alignments to even out the systems acoustic transfer magnitude. They do not exhibit quite the same issues as must be considered with passive components, so the speaker may or may not sound quite different even with an equal passive crossover. If the speakers have a passive crossover and only two leads to the internal amplifier then its quite straight forward. You can certainly convert a speaker to passive. Hope this is helpful.

There are considerable performance gains to be made by using active equalization to enhance performance/cost ratio, most notably in reducing the size of the enclosure which bears signifcantly on materials and shipping costs.

There's no harm in removing the active circuitry, but I wouldn't be surprised if the system suffered a decrease in low bass extension. This can be rectified by replacing the enclosure with a larger one with the correct acoustical tuning.
