Brass screws make a real difference on Dunlavy s ?

Thanks Peter for getting the discussion back to something useful. I plan to keep the Dunlavy(s) for a long time and as they age there will no doubt be a need to find creative ways to maintain or improve their performance. As a side note, I have had some issues with the binding posts on the SC-V(s) and have had to replace some of the midrange drivers. All-in-all, however, I think that the Dunlavy designs are 'true classics' worth the time and effort to keep them in top operational condition.

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

Merlin speakers have adjusted their driver torque setting and quoted it as one of the changes made when they launched a series update.

Great.

I'd just call keeping drivers firmly attached a good idea and leave it at that. Not worth cutting hairs about.
