From speaker for sale:
• Two-way design with twin-ribbon tweeter
• Switchable Crossover from Dynamic to Reference (comes with two keys to operate crossover switch

What does he/she mean?

Dynamic = Sound not neutral by design. But, WTF is "dynamic"?
Reference = As neutral as possible (I'd hope), within limitations of driver, design and economics.

This is a way of tailoring a speaker's sound for the application or listener preference. Studio monitors usually do this by specifying exactly what the controls affect and by how much. For example,

What speaker?
Look up the speaker on line to see what the seller is talking about.
Why would you ask this without saying what speaker it is?

It’s a Jas Orsa speaker. Never heard of it. Guess I’m not as smart as you.

So you are looking at a former $2300 set of speakers?

Around the back of the Orsa is a key-hole with two positions, marked ‘Reference’ and ‘Dynamic’. The Orsa manual was unforthcoming about the difference between the two, but a quick call to local distributor David Neilen of Sound Reference, revealed that the speakers should normally be used with the key set to the ‘Reference’ position, but that if a more dynamic sound was required, switching to the Dynamic setting would deliver it, though with a slightly more ‘forward’ midrange.

Firstly, LOLZ!

Based on the statement in bold, evidently, Dynamic has flatter FR and Reference has "BBC dip". I was wrong . So much for being literal .

Here's the blurb from the manual which isn't a lot of help, but what do you want from a company founded by "audiophiles"?
