rcompart is correct. No differecence in sound. I have actually owned the “Nazar” box and it sounded great. Below are a few of the different set ups I ran in my other Crossfire before I bought the SRT6. A JL 8W7, one of the RE Audio 10" that is in the current set up, a Focal 11" sub mounted to show off that awesome magnet, and finally 3 JL Audio 6w0's in a fiberglass plate mounted in a slot ported enclosure....
