Go to stryke.com and look at the response curve for the AV15 vented enclosure. The EBS curve starts its roll off at a higher frequency but extends lower before it cuts off, hence extended bass shelf
Hello, I have just built adireaudio's Shiva EBS aligment subwoofer with a passive radiator. I'm running it with rythmik 350w amp and the passive is weighted to 252grams. The sub has very good response lower than 40hz. My front tower speakers are okay down to 40hz. I want to build a sealed subwoofer that has great response from 40hz to 80hz. I'm not very good at using simulating programs, so any advice or recommendations will be greatly apprechiated. Thanks for your time. Justin
