Brass screws make a real difference on Dunlavy s ?

Begator, seems to me you enjoy splitting hairs. Am I to understand that tightening screws to their original tension level is not a tweak, but if they are now secured better than new and an advancement in sound is the result, that somehow this is a tweak?

I guess if drawing these distinctions makes you feel wiser and better about the discussion, I say go for it. Hey, it's a free country.

Brauser, actually your OP was focused on brass screws not tighening existing screws? Have you forgotten already? Lol

Brass balls are often cited as a useful tweak. ☝

No Brauser, I'm saying that if you're really experiencing a case of discovering a level of tightening that was either beyond the engineering capability of your speakers' designer, or simply wasn't important enough a quality control concern for the designer to care about, then you bought the wrong speakers. Think about it...what exactly does "better than new" mean? If we can agree that every screw can be tightened to a maximum torque level and perfect seating, either the speaker manufacturer assembled the speakers to specification, or they didn't. And again, if the difference between good sound and better sound is two turns of a screw, what does that say about the speaker designer if they missed that detail when designing and building the speakers? Focusing on "splitting hairs" is missing the point entirely. If you don't see this, then we might as well start a thread about how if we tighten the lug nuts on our car wheels to "better than new" the car will ride better.

If as mentioned above the DAL speakers do not use inserts and machine screws they will come loose to a degree over time, the wood expands / contract with temperature and humidity, this coupled with the vibrations form the driver it self cause this. Its not a matter of poor quality control etc.

The DAL speakers used mainly VIFA drivers, some ScanSpeak, all which can be secured with 8/32 machine screws into inserts. If your up to it Theese work great. You will need a 7/32 drill bit to pre-drill and a 4MM allen key to install them. Then get some 8/32 screws at .625 long, brass if you insist :-) 8/32 by 5/8 Brass Screws although it will not make any difference, and you will not have to worry about this again. Please remember to use a sealing gasket between the driver and the cabinet This works great.

Best of Luck
