Hi,
At Kutztown I bought a very nice Philco 118X. At the time of purchase I noticed that the loudspeaker had been fitted such that it was suspended through the cut-out in the inclined sounding board (with the speaker's perimeter screwed to the front of the ISB), rather than being mounted to it from the rear in the normal way. As a result, the grille cloth was noticeably stretched out a bit over the front of the speaker.
Once at home, I removed the speaker (which is the correct one for this model) to install it correctly. I installed four bolts through existing holes in the baffle, with heads flush-mounted to the front of the baffle, securing them using nuts from the rear. I then assumed the speaker would mount on these bolts and be secured using a second set of nuts. All was well except the first set of four nuts prevent the front rim of the speaker from fitting flush against the rear of the baffle.
Before I delve into dismantling some other set that I have, I thought I'd ask here about resolving this. Should there be a gasket between the front of the speaker and the baffle to fill this gap? Certainly on other sets I've seen what perhaps is such a thing. I don't think the first set of 4 nuts should be countersunk, as this would weaken the attachment and I see no evidence of this having been done originally. Also, I'm sure the first set of nuts MUST be present, otherwise the bolts would soon end up poking through the grille cloth.
I'm leaning towards the gasket approach, but was wondering what others may have encountered here. Also, is the cloth attached directly to the wooden baffle, or should the cloth be attached to a sheet of cardboard?
Regards,
Paul
