Which is the best epicenter (bass processor) for the price i want to spend less than 100 loking on sonic elece?

i was looking on sonic electronix i found some really cheap oones like 60 bucks not a known brand but get great reviews by hitron check it out http://www.sonicelectronix.com/item_1190鈥?/a>





here are my choices which one is the best one





power acoustik 60 bucks http://www.sonicelectronix.com/item_4011鈥?/a>





souns stream 80 buckshttp://www.sonicelectronix.com/item_2814鈥?/a>





the this sounds tream for 100 but could get it on ebay for like 70http://www.sonicelectronix.com/item_1125鈥?/a>





which one is best is there any majoy diffrences between them|||the bx 10 looks good but have you checked out the audio control epicenter? they are the original, audio control has good products for a fair price, i am not sure what they offer now but they had units that would serve different duties in one chassis.





i honestly would get an eq if your front speakers are on an amp as well as the subs.|||Call sonic,there very nice people and are very happy to help u ive been dealing with them for many years ,call them.theyll tell you everything u need to know
