Short answer: both are discontinued, so this only matters if you are buying used. Used, the MartinLogan Dynamo 700w is the better pick: it ranks #25 of 73 subwoofers by sound quality (rated 3.4/5), against #37 (rated 3.3/5) for the Monitor Audio BRW10. If you want one new, the Edifier T5s ranks #2 at $199.99.
Why pick the MartinLogan Dynamo 700w: A discontinued compact sealed 10 inch subwoofer that adds upper bass weight to movies and music. The tradeoff: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority.
What the Monitor Audio BRW10 does well: A discontinued ported 10 inch subwoofer that adds upper bass punch to movies and music in a modest room. The tradeoff: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority.
Buy the MartinLogan Dynamo 700w 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.
