Where are the subs?

In listening to the Bach Toccata and Fugue BMV 565, I was struck by how well the organ pedal notes are reproduced since I moved my primary setup to another room. I complemented myself on a fine job of integrating the Velodyne HGS-10 subs with the KEF Ref 1s, using 40 Hz low-pass with 24 dB/octave. But as I thought about it, I didn’t recall connecting the SMS-1 bass manager to the Ayre KX-5 Twenty preamp. I checked. The subs were not connected. The Ref 1s alone where reproducing that satisfying bass. Amazing for stand mounted monitors. I sure as hell didn’t expect that. To confirm, I played the Saint-Seans 3rd Symphony. Same result. Makes me wonder if I need bother connecting the subs.

Using the long port, KEF states it can get to 30Hz in-room at -6dB, so not much of a surprise.

However, audio <40Hz that needs real power is best handled by a subwoofer.

Despite the specs. I highly doubt your 10” sealed subwoofer can get to 25Hz anechoically.

Play the opening scene of the movie Edge of Tomorrow, that is an amazing test on the bass extension of your setup, it goes down to 10Hz (start with the volume low to prevent potential damage).
