Speaker companies with a focus on parts quality and measurements

I just want a highly resolving speaker. MUST it have Accuton drivers? Why do dealers look confused when I say the word "resolution"?

I second Revel. Best value w best quality. Kevin V is a great designer with superb resources. 

Thiel must be added to the list.  For the "CS" series and older, parts and crossovers are still available from the KY facility.  Happy Listening!

Unfortunately for your budget you are not going to able to find any speaker with speciality in house engineered transducers except a great pair of headphones. Sorry to disappoint you but your budget is firmly in mass market speakers with outsourced parts - perhaps if you look vintage used then you may find something.

That said mass produced speakers with parts from Seas/Peerless and others increasingly all from China can be quite good - so don't feel bad.
