I'm with TG on this. ALL of your choices are direct sellers that you can't audition without actually buying them first. The thing about these internet-only brands is that they tend to get more hyped on boards like this one than other brands, and it tends to go in cycles. Two years ago, all you heard about was the Swan Divas and nOhrs, now it's Ascend, Rocket, and Axiom that get a lot of run. Speakers are by far the most subjective purchase you can make, and often it just boils down to preference. Without hearing a lot of speakers, you can't really judge for yourself the type of sound that's available out there and what you're looking for. And never go with speakers based on reviews alone. A lot of highly rated speakers out there are not as favorable with me based on what I listen to and my personal preferences.

Ultimately, you very well might be choosing from the brands that you listed, but without a decent basis of comparison, you're going at it blind. Do yourself a favor, round up some of your favorite discs and hit up some local audio stores. Give them your price range, and see what's out there.

BTW, why do you need to buy something within two weeks? Unless you got a store credit with an expiration, you should take all the time you need for this process. It took me about two months of constant listening, comparing, and home demos before I decided on my speakers.
