Speaker upgrade advice needed
Hello everyone... I am new to the forum and looking for some speaker advice. I currently have ~20 year old speakers - JBL CF120s to be exact. I recently got a Marantz SR5007 receiver, and the sound isn't what I expected. It doesn't sound much better or louder that the 20 year old JVC I had before. I've been looking at speakers in the $500 each range, something like Polk Audio TSx550T or similar. My question is, would upgrading to speakers like that be much of an improvement? My old JBLs actually have a slightly wider frequency response range and better sensitivity than the Polk Audio speakers. Is that all that matters? What else should I be looking at? Would I need to go to much more expensive speakers to get a significant improvement?
