I might suggest a different route.
Now, I'm sure they are fine speakers but, all in all, a 5 1/4" speaker can only move so much air, and these state a sensitivity of about 85 db at about 3 feet and have a max (continuous) power handling capacity of 130 watts.
Your receiver is rated for about 100 watts in stereo (less in multi-channel) so this translates to roughly 105 db. Understandably, this is not a continuous level, but it does show that it can get pretty durn loud, even considering it's down about 6 db at 6 feet. 99 db is still pretty loud for long-term listening.
To add three decibels to these numbers, you will need to double your amplifier power to 200 watts. And, three decibels is not really that noticeable a difference.
Besides, your speakers are rated for a max of 130 watts and while they will handle more on occasional peaks, driving them constantly with much higher wattage won't prolong their life, That, plus they don't guarantee they sound good absorbing that power, just that they will live for another day.
My poi t is, your mains can't keep up with the sub when it comes to producing sound. Basically, I'd have to say that your speaker pairing is sort of like a St. Bernard attempting sex with a chiuhauha.
All in all, while more power might help somewhat, I don't think these speakers can cleanly pump out the levels you seek, particularly since the sub sets your expectations. You might want some mains that move more air with less watts.
Here's a blurb where I got these numbers on your speakers.
