loudspeaker fire hoods

Maybe not exactly a wiring regs question, but does anyone know of a fire hood for an 8 inch ceiling loudspeaker that offers 120 minute fire resistance? I can find 90 minute hoods, but this design (not ours I hasten to add) has put loudspeakers into a 120 minute fire ceiling and this is proving a bit challenging.

We can possibly change to wall loudspeakers in these areas but if we can find a 120 minute hood that would be the easiest solution.

Thanks,

Jason.

2x 90 minute hoods?

Or a 90 with a bigger/smaller 30 minute hood?

Or a multi-layered plasterboard box, might help boost the bass frequencies

Interesting thought - do the rating just add up though, or do you run into issues with how you can install them and getting the right seal from hood to hood/ceiling?

Boxing may be possible - but the ceiling is of course finished and building a bigger box through a loudspeaker cutout might be challenging!!
