My current setup consists of: Pioneer VSX-D510 RCA RC5240P DVD Microsoft XBOX Paradigm v2 Titan Mains Paradigm v3 CC-170 Kenwood CRS-159 surrounds Ported 192L Tempest subwoofer The local Paradigm dealer has Paradigm Micros for $160 CAD and Atoms for $200. I want to use them as surrounds and would cross them over at 100hz to Tempest. Do the Micros extend down to 100 hz well enough? Are the Atoms worth $40 more if they only used for surround? I am leaning towards the Micros due to space constraints and cost but if the Atoms are alot better I may consider them. Thanks.
