I recently purchased a SSA Evil 15 D2. This is my third SSA subwoofer. I previously owned a XCON and ZCON.
I originally purchased an Incriminator Audio DP15. After ordering I noticed that the new IA shredder basket was only offered on the 12" sub . It took two business days for anybody at SSA to answer my calls, emails, messages and chats. I was asking to change my order to a SSA Evil. After I was able to contact someone at SSA it was no problem with changing my order. I was happy to receive my Evil within a week. Although, it would have been great to of been informed of a new revision being released the following week .
After extensive comparing and modelling different subwoofers I feel that the SSA Evil is a leader in the market. I have not come across another brand subwoofer manufacturer that sells a sub at this price that has the frequency response, power handling and quality that the Evil has. I am also stoked to be using my first 4" coil subwoofer.
I do not have the sub installed yet. Unfortunately, I hit a deer with my car that caused $6700 in damage. I should have my car back the middle of November. I will have this sub installed shortly after getting my car back.
I built a 4.25^3ft enclosure tuned to 32hz. I will initially be powering it with a Rockford Fosgate Power T1500-1. Within the next few months I will be powering it with a different amplifier.
Here is a sneak peak of the enclosure I built.
