I've asked SVS tech support about using an EQ with my SVS sub but I also wanted to hear other people's opinions. I finally purchased the ART 351 EQ and could anyone offer some advice on how to effectively use my EQ to get better bass ? How do I find and eliminate 'spikes' and 'nulls' from my system ? I've never used an EQ before but I've heard some benefits could be attained if the EQ is used properly. My system is mostly used for home theater. The sub is also calibrated at 5-6 db over the main channels. Currently, I have a 6 db boost at 31.5 hz which works great for movies despite the decreased headroom. I like watching movies with the volume at moderate levels which would probably explain why I haven't heard the sub clip or bottom out so it's working fine so far.
