I'm interested in some electrostatic speakers for L, R, and C that with a range down to 50hz. The rear electrostatic speakers in the range that I would need to use for space reasons only have a range down to 130 hz. The G68 only lets you select 1 crossover so I think I'ld need to select 130 which seems a waste for the L, R, and C. I could set the L, R, and C as large speakers but I think I'ld need to select the bassheavy setting so the signal below 50hz sent to the L, R, and C also goes to the subwoofer. I guess I worry this won't give me an optimal result because I don't really have a crossover between the L, R, and C and the subwoofer. Guess I'ld be interested in the views of any other members on whether this would give me satisfactory results or if I should just stick with more balanced speakers which probably means non-electrostatic.
