A sticky for Speakers

The idea might come from some big studios
The idea might come from some big studios that you see them mounted IN the walls. This is fine, but doing soffit mounting is a pro job. There’s a lot more to it than just building a little shelf in the wall and mounting it flush.

Now, when you take a free standing speaker
Now, when you take a free standing speaker and flush mount it, you force ALL wavelengths to radiate in the forward hemisphere. This results once again in a 6dB response mismatch, only this time it’s heavy in the bass.

If a speaker is placed near a wall
If a speaker is placed near a wall, at low frequencies the wall will start to behave as an extension of the speaker baffle, and this will cause a boost in the bass level.

If I were going to attempt to flush mount
If I were going to attempt to flush mount those, and didn’t want to pay so much, here’s what I’d try –
Build the soffit enclosure and leave a cutout larger than the largest speaker I’d ever plan to install.

Speakers have two theoretically ideal working conditions
Speakers have two theoretically ideal working conditions. The first is if its radiation space is into a full space (spherical radiation) or into a half space (hemi-spherical radiation). To achieve ideal full space conditions the speaker needs to be small compared to the radiated wavelength. Because the speaker front baffle is small the higher the frequency the smaller the radiation angle will be.

Wooden walls are difficult to realize
Wooden walls are difficult to realize because large quantities of wood are required to ensure that there is no vibration transmission. Heavy bracing is also required to reduce unwanted resonances.
The monitors should be mounted onto rubber pads to de-couple them from the wall and avoid structural vibration transmission – in practical terms the wall should not vibrate when the monitors are played at high level.

They generally seem like a civil lot

They generally seem like a civil lot, but have a bit less tolerance for repeating answers that may have come up before; the moderators tend to be more helpful when you’ve obviously read the FAQ or earlier posts and still can’t find an answer.

I want to soffit mount my atc scm 50 s they are active so i understand they will need some air around the back for the amps


Soffit mounting speakers vs. imaging

Whether a soffit-mounted monitor system
Whether a soffit-mounted monitor system is provided, or whether the speakers are placed on stands in the room at carefully chosen positions is really a matter for prayer.

Speaker wire -> How far from electric wire?
