Not really (ha ha). That's why I am having a problem, Is having a sub with DSP worth it or should I just bite the bullet and get the EP350. I have no doubt that 10" would be more than enough, considering my 10 year old 8" Energy SB-1 kicks out more than enough bass in my upstairs system. Just want it consistent with TV and music and at lower volumes like my upstairs system. Maybe I'm just to used to the way that one sounds, but it seems I am constantly adjusting the downstairs sub gain. BTW went to go look at the DSP3100 and of course they do not have any in stock, order will be in in 2 weeks
