Martin Logan subwoofer - Dynamo or Grotto?


I'm looking to pick up a subwoofer to mate with my Soliloquy 5.0s. I am set on getting one of the Martin Logan models, and am wondering if I should just a Dynamo because they're more readily available and cheaper or should I wait for a Grotto?

I don't need a lot of SPL in my 12 x 20ish room. If anyone has any reasons why choosing one or the other would be better I'd be interested.

Happy listening!

Thanks for the reply!

Great to hear from someone who has owned both models. I wish that the Dynamo's controls didn't end up under the sub when it's in front firing mode. I live in an apartment now, so I would like to have easy access to turn the sub down if I'm listening later in the evening.

Best!

Both are excellent subs. I own two Grottos, a Depth, and a Dyanmo all installed in my theater room which is 14 x 18.

I perfer the Grotto over the Dynamo. The servo controls in the Grotto makes it a bit better sounding for music and movies in my opinion. I am also considering selling the Dyanmo because four subs is a bit too much in my room.

Good luck in your search.
