Virtually no music is down in the 20-40 hz range and I doubt the t9 can really deliver there anyway. I have a REL S5/SHO and properly set up in an acoustically tight 13x 22 listening room it does a great job of delivering deep bass- when I measured there just isn't much music at those very deep levels. Most sub activity is in the 40-70 HZ rang or so. I'd go with a larger box and drivers which will provide deeper and louder bass than the T9.
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
