Short answer: the GoldenEar ForceField 3. It ranks #5 of 42 subwoofers at $650; the MartinLogan Dynamo 700w ranks #7 and costs $999, so there is not much of a tradeoff to weigh.
One note: the GoldenEar ForceField 3 is discontinued, but it still ranks #5 of 42 subwoofers, ahead of most of what is still sold new, so it is worth considering used.
Buy the GoldenEar ForceField 3 if the ranking matters more than the price. Buy the MartinLogan Dynamo 700w if the price matters more than the ranking.
