What speaker could safely be ordered without hearing it first?

A pre-owned speaker, priced at or (preferably) below fair market value, so if it doesn’t work out, you sell it at little to no loss. That’s my philosophy.

The Borresen X-3’s at 137 lbs. ea. and built like a $50,000 speaker actually sound better to me than their $100,000 speaker. At 11 Grand for the pair, they are the best value in the speaker world currently. A beautiful piece of technology and art! Look at the quality of what is out there at $11,000 a pair. Nothing holds a candle to what Borresen is offering. This speaker has  the trickle down technology of their $500,000 speakers.Check them out. PS. there's a wait.

Never buy speakers without listening first.  Nor any other component.

If safe is your goal in both performance and budget (and checking out your room) the latest generation of Mission 770 or Wharfedale Heritage line big baffles are well made MidFi all-rounders. I confess to being a fan of the Peter Comeau IAG designs. This company doesn’t get much play among golden ear audiophiles but the products they’re producing under the English brands they now own are selling very well worldwide for a reason. Wharfedale Heritage Lintons are amazingly musical at any volume.in my high current Mogami cabled system for less than $1.5k for the pair. Took about 100 hours of listening, some DAC tweaking and interconnect clean up but they have exceeded expectations.
