Svs, Rel, or ?.

I going to buy a pair of subs to use with my Dynaudio XD200 wireless speakers for music. 

 

I can put a sub by each speaker and want to keep the size down as much as possible. Medium sized room, the signal for the sub is from a Blusound Node. I’m not a bass head, but appreciate tight, tuneful bass. 

The Svs micro is interesting to me, but I’ve read favorable reviews for Rel through the years, especially for music. Unfortunately, there are no speaker outputs for the Rel, just the Node output. (I’m not sure how critical the speaker outputs are to the Rel’s ability to blend with main speakers.)
 

Svs micro vs Rel T5i, what are your opinions? 
 

Other compact sub recommendations are welcome.

Thanks!
