So basically, what you're saying is that you're very superficial and that looks is what counts for you.
I don't think you should focus that much on what drivers Totem uses, for what it's worth, their latest speakers, the TribeIII, which sells for $3000 or something, uses the same SEAS tweeter as the Sierras. But for some reason, they seem to have oriented the tweeter vertically instead of horizontally for their left and right mains...

Also, yeah, Totem either uses Dynaudio drivers or HiVi... Originally Totem was all Dynaudio, but Dynaudio stopped selling their drivers, and so they had to turn to HiVi which offers a cheaper yet similar driver, so it's been said... Too bad you missed the 500$ Swan 2.1 sale as this should have made the decision easier...
Personally, sound is the priority for speakers, going for looks while having in the back of your mind that you might have not gotten the speakers which sound you'd prefer might nag you in the long run... Sucks that you can't hear speakers before buying them... Also not sure where you were planning to order the Swans, but be careful as some even have restocking fees, like 15% for some, so not only do you lose on two way shipping, also are hit with an extra $150 of restocking fees if you want to send them back, ouch!
