Shadorne, you are quite correct about the REL subwoofer designs (or at least the early ones).
Having had a REL Stadium II for 10 years, I found it integrated well with my full-range speakers when run from the main speaker terminals (in other words, allowing the main speakers to still run full range).
When trying to high-pass the main speakers through the REL, the degradation in sound was significant.
The Stadium !!s however, in my room didn't go much below 40 Hz, and when I added the Halcro DM58 Monoblocks to my system, they managed to drive my full-range sealed-box speakers (with 12" paper woofers) down to exactly the same 40Hz?
I now have 2 Vandersteen 2Wq subwoofers with their truly transparent passive high-pass filter and get +- 3dB down to 32Hz.
My room simply won't produce audible sound below this although I do hear pressure waves at 25Hz though probably -10dB?
