I'm more or less sold on the cantons. 4 x CD10 + CD50 (£236 via power buy - bargain) These will be driven by an SONY STRDB 940 receiver for the moment - but will be upgraded to a better spec receiver in about 6 months (pioneer vsx 2014 maybe) The questions I have are as follows: Should I go for the Velodyne CHTR10 sub or the Canton AS25SC sub? Which will sound/perform better. The velodyne quotes it goes down to 28hz where as the canton goes down to 22hz. Any comments or suggestions. Does anyone run the Cantons with a velo sub. I more leaned towards the velodyne due to its recommendations and its ease to integrate with other speakers. The other question was the cantons quote 45/80watts power handling. Why does it quote 2 figures and will my amp / future amp be too powerful for these speakers. I do not want to blow the speakers if the amp is supplying too much power. Thanks in advance guys.
