I’ve two REL Carbon Special and occasionally I’ll bump the volume up a notch when I pull the screen down and watch a concert DVD. It’s a bit of a nuisance with the RELs as the gain knob isn’t marked with positions and I can’t feel the notches which are supposedly there. Also, a couple degrees of adjustment results in too much or too little volume. Fantastic sounding subs but ergonomics could be so much better. LEDs on the sub with remote volume would be bliss!
