Hi, can anyone help me please. I’m changing from active to passive Naim SL2’s and have misplaced the Passive Crossover screws which secure the Crossovers to the back of the speakers through the rubber grommets.
I emailed Naim for the size but I’m guessing they’re exceptionally busy and up to today haven’t got back to me.
Can anyone in the know advise me of the size ie: length (I think they’re 25mm) and diameter of the screws.
Thank you
How about you go to the Home Store buy a few that look right and try it out? You can take a Paper Clip unfold it and use it to get a very accurate idea of depth. BTW don’t you have a misc. screws and stuff box?
Hi @opus thank you for the advice
Naim Allae crossover holding screw and grommet. Obviously they are from a different model but I would be surprised if they were much different.

Those look like the ones also used on SL2s
Thank you Christopher and Richard very much appreciated
An update on the screws for SL2 crossovers from Jordan in Naim Technical Support.
“The required screws are Metric 3.5 x 20mm Pan Posi head self-tapping screws. The Imperial equivalent is 6g x ¾” self-tapping screws.”
Unfortunately neither the screws or grommets are held in stock at Naim.
Thank you Jordan most helpful.
It’s not strictly necessary to fasten the crossovers to the cabinets, it’s okay to simply let them dangle on the NACA5 as so as they don’t touch the cabinets.
Some say this is better, no doubt due to less vibration affecting the crossovers 
Debs thank you, I have heard this mentioned by other SL2 owners. I’ll experiment and see which method I prefer.
At Naim we preferred having the crossover supported by the screws and grommets but not coupled closely to the cabinet - just doing up the screws so they touch the grommets without compressing them. Letting the crossover hang freely was found to be not as good, perhaps because it then put a bit stress on the connector pins which could give a slightly poorer contact, rather than allowing them to find their natural best fit within the socket.
Thank you Richard I will go with the Naim preferred method.
