Ceiling speakers and fire hoods

[new_bloke]

Hi all - I've had a bit of a search, but not found anything that helps a great deal - forgive me if this has been asked in the past. I'm currently installing some ceiling speakers in my kitchen, and feel I should also install fire hoods (given that we're in a bungalow and that the ceiling goes directly to the loft).
I've seen the hoody products, but they do seem rather pricey. Are JCC any good? The speakers are monitor audio pro-ic 65, so the cutout diameter is 200 (wish) mm.
Any thoughts, recommendations would be gratefully received.

Thanks all. I too am a little confused by the distinction in application between downlighters and speakers - I guess my question would be: Would anything bad happen if I did use a hood designed for downlighters?
Fire prevention is the primary concern - I'd also like to protect the back of the speaker units from ingress of dust and the general muck in the loft space. If there's a bit of noise isolation then great, but I am not too worried about that.
I'll take a look at the ansel hoods...
