I am pretty new in this group, so I apologize if I ask questions already answered in the past.
I have a pair of Falcon LS3/5a speakers, which I listen to near-field (1m from the listening position and several meters from the rear wall). They image like crazy and simply disappear from the room.
I love those little monitors, but due to their shoe-box size, they lack bottom end. I have been thinking of adding a subwoofer (I had a couple of models in mind), until I stumbled upon the GR research servo-controlled subs. Unfortunately, the LS3/5a BBC monitors (like my Falcons) are notorious for their mid-bass bump. Here are Stereophiles’s measurements https://www.stereophile.com/content/falcon-acoustics-ls35a-loudspeaker-measurements
Some say that the mid-bass bump makes a subwoofer integration impossible. I am wondering whether a subwoofer with PEQ might do the trick. But hi-fi purists claim that a DSP will just kill the fine details in the bass. I am no expert, so I do not know what to believe. I have in-room measurements of my speakers, performed by an expert, which that might be helpful...
Looking for quality and not quantity of bass, I would like to find a way to improve my Falcons and not to compromise their character (they "live" above 70Hz). So...
1) Sealed box or Open baffle subwoofer? i.e. Kit 2 or kit 4?
2) One or two subs?
3) High-level input on line input?
Are the servo-controlled amps of GR research supported by a mobile app for setting the subwoofer parameters?
Thanks in advance for any replies.
