[QUOTE="helotaxi, post: 5067379, member: 550915"] The SPL spec of a sub has no bearing on how efficient a sub is in the lower bass regions. By definition a truly overpowered sub will sound like utter shit because it is being driven beyond its capability to respond in a linear manner. There's no such thing as an "underpowered" sub either. The idea that you need to match the rated power of an amp to the rated power of the sub is really dumb. The fact is that you can run an amp to a sub that is rated significantly higher than the sub without issue provided that you are playing music. The reason is that the sub's power rating is based on a continuous sine wave and music is nowhere near continuous. You can also get a sub plenty loud for normal listening with an amp rated considerably lower than the sub. You get the most marginal gain at lower powers. For example to get the same amount of gain as going from 1 to 64W you have to go from 64 to over 4000w. Also as you increase the power level the realized gain from more power is reduced further thanks to power compression. [/QUOTE]
