Does anyone use this product with their base shakers? FMOD CROSSOVER PAIR 50 Hz LOW PASS BY HARRISON LABS At partsxpress.com part # 266-250 I hear that their not that good, but i wanted to hear from some people that actually use them in their bass shaker systems... I can get those for the 25 US plus 15 shipping and then convert that to canadian.... ugg. plus taxes... or i can just buy a active electronic cross over for 135 up here, which would give me more control and probably better quality then the inline ones... Clarion MCD360 3-Way Electronic Crossover but im trying save as much money as possible. any ideas?
