you are right, it isn't a frivolous exercise, but it is a goofy question
you can order any speaker (or any component) unheard, you just take the risk that you may not like what it does, then have to dispose of it, at a cost of money and effort
this is what the used gear market is all about - you buy what interests you, see if you like it, then resell at a reasonable price if you don’t
