I currently have Technics front speakers that I bought about 5 years ago with 140W capacity. I recently purchased a JVC 8010 that is great, output 120x2 and 100x5. I also bought a Technics Center/Rear package that sounds good, but the fronts just don't seem to be putting out the output they did on my old two-channel receiver. I have to turn up the new receiver to about 40 on TV and 60 on DVD (max. vol. is 99).I did read in one of the threads that this is sometimes normal. Do I need smaller speakers? Also, I don't not have a sub yet, will that make the difference? I am new to HT setups, so any advice would be great.
