I had reported above that I added a KEF62 to the Falcon Kingswood Warrens. I meanwhile received my 2nd KEF62. I am driving the subs in Stereo now just parallel to the Falcons with the low pass to the subs set to 60Hz. The result blew me away. Adding a KEF62 is a great idea in the first place, but driving them in a stereo configuration makes 1 + 1 more than 2. I had hoped it would add even more ease to the whole set up, but I was not prepared for this. Forget about a debate whether stereo subs make sense, it transformed sth that was already a great upgrade into a system with even more ease. I hear no sub, just full blown instruments , pianos, contrabass, electronic bass, so much fun. It took even more strain from the Falcon sound, opening everything up even more. I am moved by the difference this made. Best 3000$ I ever spent on Hi-Fi. So let’s reflect what happens here: you have the superfast Falcons that punch and sing, jut not loud at all, but can’t deliver miracles below 60Hz. Now you add 2 dipoles (4 superstiff 5“ membranes), which fire evenly in the room, not against the floor, accelerated by 2x 1000W of amplification. And the perceptions of loudness, space and ease comes from the bass < 60Hz. It works fabulously and now they sound like fast, precise big speakers, without loosing the speed. Placement and messing with the crossover took me 5 min, it’s that easy. Conclusion: 1. The Falcon LS3/5a work fantastic with the KEF62 (one sub, placed in speaker axis in the middle between the speAkers). It is fast enough that it seamlessly integrates. 2. Adding a 2nd sub and driving them in stereo configuration makes a bigger incremental difference, than adding the first sub (which is already amazing). 3. the Falcons easy to place, so are these subs, I have them just next to the speakers. And they are so small that they don’t change the small speaker experience which many of us enjoy about the ls3/5as.
