I've read some of the posts here answering questions about subs and the frequencies. I've noticed that some of you have eqs hooked up to your SVS subs or what eve subs you have. Here's what I have, I have the two DIY subs hooked up to a Numark mixer with volume control and a six band eq. It sounds great but I need to update and replace the mixer. 1. Do you have a 10 band or 12 band eq hooked up. 2. what are your settings, the frequencies. 3. How does it help, what does a 10 band or 12 band do to the sound. Thanks for your help.
