Peerless/Tymphany TC9FD18-08 Mounting Question

[tomzarbo]

To anyone who has used this driver...

I'm getting ready to begin a table radio build using this driver. It looks like it's going to work really well for my needs, almost perfect, actually.

I have one question, though. Maybe it's just me, but I wonder why Peerless made the mounting holes so dang big?
With a driver this size, I'd usually use a #6 or even #4 as I really like the smaller screw sizes. The hole just seems really large for this size of driver.

Here is a pic with (L to R) #8, #6, and #4 screws, and the same flipped over. The #4 almost slips right through the hole and the #6 seems pretty loose. The #8 fits really well, but looks huge on the flange.




Guess I'll go with door #6 for this one, but I just thought it was slightly odd that a 3.5" full ranger had an 8" woofer screw hole in it.

Oh, and while I'm griping...
...would it have killed them to include a mounting gasket on the backside like the one they already have glued to the front? I know, I'm really nit-picking here, but you know... Dayton would have.

Maybe the large holes are to allow some slop in drilling the holes in the baffle? In any event I'd use a washer under a smallish screw.

That specific driver appears to be for rear mounting. Mine looked like this. https://th.bing.com/th/id/R.15d19923...pid=ImgRaw&r=0

I have a few like that.
If it was not plague times, we'd be visiting family around Philly, and I'd bring them to swap, but it's probably not worth the shipping to make a neater installation.

If it is, let me know(I'm sure only you will see it- it's the hobby)

Ahh, so it was made for rear mounting then.
That explains the gasket on the front and not the back, (I wondered if it had some acoustical benefit.)

I suppose that a larger screw hole allows for a bit more flexibility for mounting options if it were to be rear-mounted as well.

Thanks for the insight fellas.
