well whoever told you that is dead wrong...
they do indeed come from the same place.. but they mock up, sound, and perform quite differently..
results from the great 8 challenge disproves them being the same really quickly..
they didn't come close to matching each other in subjective listening, overall output, or frequency response..
the crystal sounded vastly better, but the true bass was nearly 4.5 db louder overall..
sounds like another one of those "looks the same must be the same deals"
