Short answer: both are discontinued, so this only matters if you are buying used. Used, the Definitive Technology SuperCube 2000 is the better pick: it ranks #5 of 73 subwoofers by sound quality (rated 3.7/5), against #25 (rated 3.4/5) for the MartinLogan Dynamo 700w. If you want one new, the Edifier T5s ranks #2 at $199.99.
Buy the Definitive Technology SuperCube 2000 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Edifier T5s instead.
