New buy, no return policy

I am negotiating a sale with a reputable, but small dealer for a pair of new Acora SRC-2 speakers. I have heard them in the showroom with comparable electronics to my own and loved the sound and design. The show room was only slightly acoustically treated.

I'm ready to throw down, but the dealer does not have any kind of return policy if, for some reason, they dont work out in my own space. I dont feel comfortable with this policy but wondering if I am just being too entitled?  Other dealers from which I have purchased new speakers  have had 30 or 60 day returns, no questions asked. 

I also have the opportunity to buy a used set of these speakers from TMR with a return policy (minus 5% ,restock) if not satisfied. Of course the used price is considerably cheaper but there is no factory warranty and although they are stated to have had own owner, their age and provenance are unknown.

Any guidance, opinions or advice?
