I provided the hardware info the exact speaker specs and the model of the avr if you are missing info why not ask a specific question. I like the link you posed but is it the best choice seeing as it seems like it has a bit more power then I need for a 300peakwatt 3 way speaker
The whole point here is that you haven't convinced anyone but yourself that you need more power.
If you think you need more power, then buy a beast of an amp. If you still have the same problem, then you know 100% for certain that power is NOT the problem. (I doubt you can add an external amp to a low end AVR though)
You need DOUBLE the power to get 3dB sound pressure level increase!
If those CV are REALLY 93dB, then lack of power is almost certainly NOT the problem.
If a speaker gives a "power handling spec", I completely ignore that pretty much useless spec! As do pretty much all the other experienced forum users.
Try to run the speakers full range, no crossover, no room correction, stereo mode only. Does that get the sound you want? If it does then you know that it is a setup or configuration or RC problem. If it does not, then you can proceed down the list of troubleshooting options.
At the very least, you owe it to yourself to try the FREE options BEFORE you drop more $.
I hate to tell you this, but my gut says "buy better speakers". But, you may be able to get them to a sound that you like. Mind you, I'm not bashing CV, I like them for what they are---a "party speaker" may be a good description--and that is one reason that we are not convinced that power is the problem.
