@Pogre - I have been unboxing and trying to find the best way to integrate the Ascend Sierra Towers into my setup. I was using Paradigm and VMPS SuperTower III's as my front speakers. They worked well together as the Paradigms play well at lower volumes and when the sound level rises the 7 foot towers kick in for killer, fat, wide powerful sound.
After going thru several combinations and Audyssey EQ sessions I found setting up the Sierra Towers with RAAL 70-20 tweeters in the Front LR position while using the VMPS Towers as front surrounds works well. This gives me Stereo mode for listening to the Sierra Towers and HSU subs alone, Auro-3D mode with a 9.2 configuration or Multi-Channel Stereo with fronts, center, surrounds, rear surrounds and highs.
The Sierra Towers are more sensitive than any of my other speakers -- with an SPL over 90db from 250Hz and up. The RAAL 70-20 opens my ears to things that were not apparent with my other speakers. It's usually lower SPL percussion or a singer taking a breath or other small details that are not obvious. Rather than calling them silky smooth, I would call them a little on the edgy side. That's what brings the high definition. They have a different flavor than my Canton Vento 9.2 DC aluminum ceramic oxide tweeters that seem a little smoother.

In Stereo mode 44 reaches 80db on the Denon 4500 using the Adcom GFA amp. In Auro-3D 9.2 mode 50 on the volume reaches 80db. This happens as Audyssey reduces the Sierra Tower volume to match the other speakers. And in Multi-Channel mode 40 on the volume reaches 80db. It's interesting comparing these configurations. They all sound great but for pure Sierra Tower sound the Stereo configuration provides a nice music mode while Auro-3D smoothes out the sound a little.
I have a few questions for you.
1. What crossover setting are you using on your Sierra Towers in the Denon Receiver? 80, 60, 40 in the Denon crossover setting?
2. How did you setup your HSU subs? Do you cross them over at 80 or higher?
3. Do you use LFE or LFE+Main?
4. Do you notice a difference playing the Sierra Towers with grills on vs off?
These little 50 pound speakers have more sound power than anything I have ever used in this size class. I would expect the Sierra Tower sound power to easily beat speakers 2x their size. I was laughing to myself after completing these tests that these little 43" x 7.5" x 10.5" speakers can almost replace all of the 9 speakers in my 22' x 28' listening room.
I love the bamboo natural finish. It's really classy and looks perfect from every angle. Most of my speakers are just black boxes. I hope my wife doesn't come down to my cave and see how beautiful these are. She might want them upstairs, then I would have to buy another pair.
Thank you for suggesting these wonderful speakers!
