I'm confused, you say you don't see the advantage:

The RAAL tweeters are amazing, but I think the true magic of the Sierra Towers is in the mid-frequency range. Dave has selected a cost-effective high quality driver that performs superlatively in the frequencies which are delivered to it.
This to me sound like an advantage. I run a pair of funk 18.0c placed in stereo (happened to work well with room modes cause of funny room shape, they are till summed mono), so I have no need for low end performance and can cross as high as is required. I live in an apartment, and am limited for space, plus aesthetically I prefer bookshelves. I actually did price out a custom horizon center, but it's still got a lot of volume and port tuning for a range of audio that I will NEVER EVER use.
I have no intention of trying to push for a low crossover (I'm currently running 90hz just cause thats how things ended up, but 80 is fine too, but I was also equally happy at 120hz). So I literally NEVER use most of the volume/port tuning of the tower. Given how much a ported enclosure can improve efficiency, if nothing else I'd prefer something tuned to a higher port tuning that actually targets the range I am aiming for so I can get more overall efficiency. Also, to the best of my knowledge, the midwoofer of the tower is sealed anyway, which means it should work just as well regardless of enclosure, so to me, a bookshelf with the midwoofer makes way more sense than a big unnecessary woofer.
Bare in mind, I also ordered a pair of custom white Sierra boxes to swap my Sierra-2 guts into just because aesthetically I wanted white speakers. Custom or high cost doesn't really bother me (within reason). I'm actually contemplating seeing if he could build a 3-way bookshelf with the diamond tweeters he's been playing with.
Also, with bookshelves I have the option to use the same speaker for Mains and Surrounds
. I contemplated towers as surrounds, but that just seems overly imposing, plus they aren't really tall enough for that.
