What speaker could safely be ordered without hearing it first?

@mtbiker29 , no. Just no.

As others have mentioned, there is no substitute for auditioning candidate speakers. Case in point: I was intrigued by a certain open baffle speaker vendor's product. Reviews are mostly positive and the quality seemed to be good. Then last year I heard a pair at PAF and was sorely disappointed in what I heard. And it wasn't just the room. They just didn't sound good to my ears.

The moral of the story here is, if you do order up some speakers, I'd be very clear on what the return/exchange policy is.

Good luck and... Happy listening.

None can be ordered “safely”.  Speakers are part of an audio chain whose job is to create “subjectively” pleasing music.  I’ve spent years demoing the best speakers I could find, then tried to replicate the favored sound within my budget.  
 

If the OP is asking for the the best choice without trying, then maybe it’s a probability question aka maximizing the probability of success by choosing a popular seemingly universally appraised speaker.

If I’m you I’d do all the research I can and then buy used as others have said. If they don’t work out you can sell and move on for little/no loss if you buy wisely.  Also hard to see going wrong with Fritz if he offers a return policy.

@phishhhhh4 I tried to get my band to play “Backwards Down the Number Line” that I think is great and would be fun to play, but they’re idiots who have their heads stuck in 70s - 80s rock. Very frustrating.

Quad 57 from Electrostatic Solutions. 

Think they are now $6K.

I have owned Tannoy Westminster Royals, ATC Anniversary 50, etc.

Once you hear the tone and transparency of 57s there is no going back.

Human Speakers model 81 DK ... aprox $1250 / pair
