Adding an Sub that doesn't go well below speakers?

The backbone of my setup is based on a couple of Canor Monoblocks that feed a pair of Marten Oscar Trio. The trio are rated for 27hz (-3db), but I still feel that the system would benefit of having one or two subwoofers that help both of below 27 while also allowing more breathing space for the speakers.

 

I was considering a couple of REL T5X because of the little footprint as well as the high line connections (the amps don't have a dedicated low-level sub out). But just before pulling the trigger, I saw that the T5X is rated at 37hz (-6db). 

Would it make sense to add them to the system? Doesn't sound right. I know probably the Martens roll off above 27, but perhaps 37hz sub is too high for my system.

Perhaps a T9X that goes to the same 27hz? Or do I definitely need to splurge and do for an S series, like the S510 that is rated at 20 hz? If I do an S510 I will do just one and add a second once my wallet recovers.

 

Well, would love to hear from you.

Roll the bottom out of the mains from at least 40Hz with a passive first order filter to the main amps

2x Martin Logan 800x or better. Any similarly capable sub with multiple XO slope, 180° continuous phase, polarity inversion.

OR

miniDSP 2x4HD if using digital source or analog active XO. Note the analog inputs on the 2x4HD are not acceptable for HiFi. The advantage of digital XO is time delay. With analog XO, you have to shift the woofers about more for the best integration

 

NEVER EVER use the high level inputs on a subwoofer if you are serious about sonics.

How do you do this?

 

Without instrumentation, the best program is something that has a lot of air, significant low end and plenty of mids.

Being of Scots heritage, I naturally had well recorded Pipe and Drum bands. It’s the best program ever for dialing in subs. When you get it right, the focus snaps in!

Bach’s Toccata and Fugue in D minor recorded in a great space is also a favorite.
