What speaker could safely be ordered without hearing it first?

This is like ordering a mail order bride! Don't do it!

Since I like to 'compare and keep', I bought an SVS center speaker so I could compare with my current and took advance of they really 'no questions asked' try at home police. Ordered. Tested for 2 weeks. Put back in box. Received return label. Mailed back. Refund. Super easy. 

a smart person will never do that, but the mind comes with experience... unfortunately most audiophiles make their purchases based on the opinions of people they don't even know (critics from advertising articles, sellers from electronics forums) .... then disappointment, sale and buying new devices...
after a few years, such people themselves give generous advice to beginners))) - they sell their scrap metal to them and get cursed ...

Anything Sonus Faber. 

I have always felt comfortable buying B&W speakers without hearing them and have done so several times but I agree with many above who say don't buy speakers without auditioning them first.
