Hello, I just finished my 85 liter ported box for the Shiva, but I havent got the Shiva yet. i was going to order it when I finished my box, but I have run into a dilema... One of my friends told me tha the Stryke SAE1204 subwoofer went on sale for $109.00!!! I checked it out and it looks to be superior to the shiva in many ways. (cast basket, bigger magnet, and voice coils, 5 way binding post terminals) Should I order the Stryke instead of the Shiva? Have any of you had experience with stryke audio, or the SAE1204? NOTE: the reccomended allingnmet for the stryke sub is a 3cu. foot ported box, whick is exactly what i got. my amp is a PE 150 watt plate. it will be crossed over at 80 Hz. I am looking for good SPL with my weak amp, and good tight sound. Which driver will be best?
