Subwoofer matching


I was all set to pull the trigger on a pair of REL subwoofers.  These would be used with my Avangard Duo’s and Pass Labs XA 60.8 monoblocks.  My main music is Rock, Jazz and Blues.  I have been given advice by a few people now saying the 107 efficiency of the Duo’s will make it very difficult to find a matching paint odd subwoofers.  Feed back I have been given is “... it will take a powerful subwoofer to be able to match the output levels of your speakers“ and “The only REL model that may work for this application will be the 212/SE, which has a very powerful amplifier that will allow it to blend well with your speakers.”  A pair of REL 212/SE is a budget breaker for me.  I am in not position to judge if the advice is correct or not.  Does anyone have experience negating a pair of subwoofers to a highly efficient speaker?

The quoted words of caution are from REL customer service.  My I am suspicious but they recommended two of the biggest most expensive subwoofers they sell.  The REL recommendation was seconded by a couple of friends.  I am also considering SVS subwoofer.  They did not seem to think that their subwoofer would have a problem keeping up with the AG Duo’s.

The reason I am not keen to buy AG subs is that I don’t want to have flexibility issues later if I migrate to a different main speakers.
I will look into HSU.

Acresverde, the goal is to complement the current speakers.  Not considering replacing the bass drivers that coming with the AG duo’s
