  • How does it compare to SVS SB1000?

    • +1

      The SVS SB100 classic has a quoted frequency response of 24Hz to 260Hz (+/- 3dB), so digs a lot lower. It is also a good deal smaller at 342mm h x 330mm w and 375mm deep.

      Price is $799, but I bought one for a friend recently for $760 delivered. just by asking for a better price.

      • Is reaching down to 24Hz better for music? Or is that more of a home theatre thing?

        • Frequencies that low are relatively frequent in movies but not so common in music. If my use was music only, I would still rather have a sub that is capable, than one that isn't.

          That was bought from CHT.

        Also which retailer did you ask?

      • What about the Polk XT12? That's $600 on Ebay right now. It is also 12" and can reach down to 24Hz. However it can only output 100W continuous (as opposed to 300W) and it's range tops at 160Hz.

        Does continuous wattage even matter if the sub is going in a small room? Like I would think 300W is probably more suited to a more open living area, and overkill for a bedroom.

    When comparing subs you have to know what dB level the lowest frequency is quoted at. One that goes to 20 hz at -3db is superior to one that goes to 20 hz at -6db. -3db is the original standard but manufacturers started cheating by quoting at other levels like -6, even -10 to try to make the specs look better to the uninformed reader.

    Every 3db difference is equivalent to halving tbe output power of the sub at the quoted frequency. So a frequency quoted at -10db is output at a quarter of the power compared to the power of one at -3db.
