Do I want tower speakers? I say tower speakers because of the full range of sound?
Hmmm... "the full range of sound". Are you clear about what you mean? Let's look at some examples.
#1: 45-20kHz
#2: 48-20kHz
The difference between 45-48Hz is about 1 note, (F# to G), in the lowest octave of a piano. In other words, not a big difference. However, there is one big difference in the 2 speakers above.
Speaker #1 is the Aperion Verus Grand Tower. Winner of the 2015 Audioholics Top AV Gear Guide for High End Floorstanding Loudspeaker.

They cost $1,000 each.
Speaker #2 is the Philharmonic Audio Affordable Accuracy bookshelf. It continues to receive rave reviews and support from the members here. They cost $195/pair.

I have a 7.2 system. The 4 surround speakers are the Aperions above. I use towers for surrounds simply because as I replaced the front speakers, I moved the old ones to surrounds. If I was starting over, I would get the AAs for surrounds, and put them on stands. $400 vs $4k.
So, IMO, "full sound" is not a good reason to get towers over bookshelves. You
can get more "full sound" from towers, but at a price. A significant price.
BTW, the R-26F is 38-24kHz, and cost ~$350 each. From what I hear, the sound of the Klipsch is likely to be sharper/brighter than the other 2 speakers above. Not more accurate, just brighter. Some people like that, and you may be one of them. But my point still stands. Towers are not necessarily "fuller sound" than bookshelves.
