Recess mounting of FR in 25mm thick baffle

[sumotan]

Hi Guys,
Is it a bad idea to recess mount speaker even if I chamfer the outer edge by 45 degrees or more.

Thanks

It's fine to radius the baffle to allow rear mounting of a woofer. With a FR it becomes difficult to say either way.

Thanks Allen that's my concern too hence.

What FR?

We recommend a full 45° chamfer for a full range. You don’t want early reflections backthru the cone.

Many thanks Dave. Apologies should have be clearer in my description. What if I mount the FR behind the baffle would chamfer of 45 deg or more in front part of baffle help would the stop reflection ?

You can model it with Polystyrol and measure it. If you put it from behind

We tried that once. Didn’t realy like it. Will depend on the FR.

But if i was putting it on the front i would start with 45° and then round the edges further.

Thanks again Gents. Its a Coral Flat 8.
I believe this speaker was originally design for rear baffle mounting as the gasket is place in front & its got a circular recess on the stamped still frame for mounting

That is pretty standard.

The gaskets are usually paper. I have often trimmed it off flush with the steel basket edge, and then rebate and mount from the front.
