    Looks like the tunning ended up around the right frequency and the curve is relatively flat.

    yeah, that looks real good.
    Was this at a typical seating position?
    you should try all the *key* seats...just to make sure there's not one or two that have big problems.
    I bet it sounds killer with music and film?

    Actually that is just at 1.5m from the bottom of the sub. I haven't tested it at my seating position yet but will do that tomor. The room is actually my bedroom so there is really only 1 seating position on my bed [​IMG] So far I am extremely pleased with the Sonosub and the Fidek amp.

    TV,
    Here is some seating postition numbers. My seating position is 12ft away and elevated on a bed, so the seating may be higher than a typical couch(if that matters)I also added 15 Hz test to this. This was the same test procedure(everything taken at 75 dB reference.
