Frequency Response

Definitely. My remote controlled subwoofers are simply fun. With the exception of certain LP's I prefer the systems presentation with the subs on and using various gain settings. 

SVS offers a painless trial period that might help you decide. I can't speak to their quality. 

The low frequency response for my speakers is 26Hz +/- (1.5 dB anechoic). At my rooms listening position they fall to 0dB at approximately 31Hz. My subwoofers most used customized EQ preset is just over +2dB @ 37Hz -18Hz as well as the variable Q, slopes and filters.  

@onhwy61 the room size is 17.5X14  and the speaker is the muraudio SP1.  Once again haven't heard live but like the design.  Do I get a decoder ring and secret passcode?  I listen to a broad spectrum from rock/hard rock/pop/jazz and classical played from loud to ears bleeding to background music

my speakers are -3 db at 32 hz and a pair of REL made a wonderful difference

For $20K and not hearing the speaker I'd ask if they took it to Canada NCR anechoic chamber for testing since they are made in Canada. If so ask to see the spins.

 To the OP, pay attention to the posts from @djones51, ​​​​@onhwy61 above

it starts with how the speakers were measured and the room 

your working with.
