Yes, that setup should do it. If your bass sounds balanced and natural, you're done. If it sounds slow and overloaded, try moving the stand-alone subs to different parts of the room until it sounds right. You can excite room "modes" if a sub is in the wrong location.
Subwoofer for music, how low?
I am looking for a pair of subs for music. I plan on having four if the two can blend with my speakers.
I have the Tekton Double Impact and tomorrow I will get a set of Buchardt S400Mk2.
I have been looking at the REL T/9x but the only go down to 27Hz at -3db. Should a sub not go down to 20Hz?
I live in Denmark so I have fewer options. I really like the swarm sub array but to costly to get it to Denmark.
I am looking for recommendations. It could be DIY or a specific sub.
I am open for suggestions
Merry Christmas
