Brass screws make a real difference on Dunlavy s ?

Dunlavy speakers have no threaded inserts. Dunlavy speakers do sound better with brass machine screws on all the drivers as well as the tweeter mounting face plate. Replacing the steel mounting hardware with brass on the crossover back plate ..improvement there can also be heard.

Brass is the metal of music. Brass will also interfere less with the flux field whether that field is stationary or moving. The use of brass fasteners are beneficial on most every type of application in audio electronics. Tom

Also energy can be drawn in a particular direction by mechanical force or tension. If you have a speaker driver that is to be secured with multiple fasteners then all those fasteners should be tightened the same. Like a drum head the energy should be spread evenly around the circumference. In this way the wave launch from the driver will be more linear and piston like on all areas of the cone or driver. Tom

Never known of any speaker manufacturer to adjust the torque on any of their speaker drivers when mounted into the cabinet and this includes DAL.. except one for sure. If any were indeed factory set there has never been a setting quoted in a shop manual. If there was a quoted torque then that factory setting has changed over time. The screws that hold the mounting frame to the Vifa tweeter mentioned above are metric steel and should also be replaced with brass as these are very close to the moving voice coil and dome. Tom

Great.

If you cut all those hairs its called good grooming. In this case better sound. All in the details leads to more and better detail. Tom
