There are two camps in the battle. The first is the SVS camp. Their subs are aimed for a flat frequency response, which results in an in-room response with a hump in the lower frequencies. The second is the Tempest camp. Adire says there should be a "drooping" response in the bass to make it as flat as it can be. I'd suppose SVS has an edge in Home Theater, whilst the Tempests have the edge on accurate music reproduction, since a flat frequency response would also imply a worst transient response, plus the extra bass would muddy the lower frequencies. Am I right, or is it too early for me to think clearly? Javier.
