I came here for help and calling out the I'd think rather obvious ignorance of some aspects is unhelpful, kinda rude and pointless the only reason I'm here is try and find out what I need to know/buy. the only purchase I've made is a Avr replacement. I'm still within the return window for the avr. It's obvious the main speakers are being under powered just based on sound. The mains are set as large and have the crossovers set to lowest denon allows for main that is 40 doesn't that mean when when I stereo and not surround it's still limiting the band. I want the fronts to preform while surround is on as it stands they sound Lil different then the 2 way 8 inch floorstanding surrounds
If I can chime in here on a few things:
1. Make sure your speakers are set to LARGE in the bass management
2. If you're not using a separate powered sub connected to the sub out via RCA connection, then set the sub to "No" or "off". This will route the LFE and summed bass to your main front speakers.
3. Set your center and other surround speakers to small and 80Hz crossover.
4. Level match all of your speakers using an SPL meter and the internal pink noise of your receiver at your primary listening position.
5. If you don't feel you can play loud enough, consider getting an external amp to plug into your receiver.
6. Educate yourself reading articles on this site such as this:

#6 is most important. Power ratings/handling of speakers can be very misleading just like power ratings of receivers can be. You don't need to match them b/c its a nebulous goal. I understand your confusion but you're getting a lot of great advice here so listen to the experienced forum posters and do your homework.
