Am I underpowered with my speakers? I have the paradigm titans http://www.paradigm.com/Website/SiteParadigmProduct/ParadigmModels/Performance/PerformanceSpecs.htm I have 4 of them for my fronts and rear surrounds. I also have the paradigm CC-170 on the same page above as my center. My sub is the PDR-10 http://www.paradigm.com/Website/SiteParadigmProduct/ParadigmModels/SubWoofers/PDR_Series_Specs.htm Are these good speakers to keep. I have the chance to move to the Monitor series from Paradigm with removeable front grills....the titans do not have removeable ones? Anyone have any comments? The sound is fairly nice wiht my setup...I just want the best bang for the buck and not want to under achieve with my receiver/speaker combo.
