Here's the possibly disturbing line from the currrent REL site (the "FAQ'S" section, "6. Which REL sub-bass system is best for me?":
"Acoustically, either the 'ST' or the 'Q' range work excellently in either a hi-fi or home cinema system. However, the inputs on the 'Q' range are slightly more oriented towards home cinema use."
They do say "slightly"...I feel better already. Also notice that they no longer make the "Q" series. My beloved Q150E has all the adjustments one could ask for in a sub: Phase, frequency, level for both input types, and a weird 2 position knob for disco freaks.
