Looking for opinions on the Pioneer VSX-1130-K receiver and matching it with the Polk RTiA1 125W speakers. Is this a good match. Probably purchase two to start and as funds permit progress to full 7.2. Looking for suggestions on any speaker(s) for this receiver. Best front speakers? Best rear speakers. Best side speakers. I already have a sub-woofer but will ultimately add another. I guess what I am asking is for suggestions for speakers for this A/V receiver. The area for the system is about 15ftW by 45ftL. Prefer to have speakers off the floor i.e. on stands to bring them up to mid room level. Thanks to all who have a suggestion to make. Limited budget, by the way.
