In the process of changing over from a rainbow audio passive two way system to an Ausion Vove 3 way active system. Im currently looking for a DSP and am stuck between two of the cheaper options. I can get a DSP-408 for around £170, but i can also pick up a second hand Helix DSP mini for £200. However because im going 3 way active plus a sub, i will need 7 channels, which is beyond the scope of the helix. However im wondering if i would be better off with thw helix running the front 3 ways and just keep the sub individually controlled from my Pioneer SPH-DA120 head unit? Is there much advantage of the sub going through the DSP?
Thanks for the help
