Proper surround sound

[Kelvin]

Open backed speakers like these typically should be mounted so that they are enclosed. It improves the bass, and reduces sound from travelling to whatever is above them. There’s also a fire regulation depending on what is above them. I fitted all mine inside a fireproof hood and the difference in sound quality vs just having them open was significant.

I did read that . I assumed they don’t actually output a lot in atmos ? . Beam and block above so not really worried about sound transfer. Did look at ‘official ‘ sound backing boxes - ridiculously expensive. Link to yours ? . Fire regs 😂 - off a (expletive deleted)ing speaker in an underground house 🤣🤣🤣🤣 - don’t think I’ll worry about that one . Back boxes though for better sound ….. yes please

The fire regs aren’t to do with the speaker going on fire. You’ve cut a big hole in your ceiling and if there’s a fire in that room it can spread more quickly as the speaker is made of plastic mostly. I have two in the kitchen which has a bedroom above it for example. Depends on the room and what’s above it. I fitted them to improve the sound though. 
 

They do output quite a lot. 
 

Take your pick. You can size it to your speaker. You will need to cut it to fit. They are a pia to fit but with your 1980s office ceiling it will be  easy for you.

Yeah but it’s like 50 quid for 1 and I need 4 !

 

I’ll install as is . Then it can bug me “ would it better with an audio hood ? “ for a bit 

 

In this open plan room I’ve just counted 35 lights / sensors etc that are all holes in the ceiling 😊- so I take your point ; but I ain’t worried about that . The leak will put the fire out anyway 🙄😂.

In a previous house I made MDF acoustic boxes lined with acoustic foam. Knock something up.

Will I really tell the difference audibly ? . I suppose I could make 1 and try content with and without it installed I suppose . So just bolt a lined box over the speaker essentially?

Speakers are fitted into enclosed boxes for a reason other than to stop them falling on the floor. 
 

The difference it made to mine was very noticeable.
