flush-mounting monitors

[The Garage]

i have a few questions about flush-mounting monitors.

1) is it advisable to flush-mount nearfields or just midfields? would you flush-mount your mackie hr824s?

2) the sae site explains that you build a tight box around the speaker. is this box then built into the wall or something? i understand that the speaker surface should be flush with the wall, but the sae diagram shows a bass trap under the monitor, not a wall. the wall is beind the speaker. or am i reading this incorrectly?

3) where do the cables for the monitors go? if you drill a hole in the box, doesn't that defeat the purpose of the box being completely airtight?

4) how do you prevent overheating?

thanks.

Midfields mainly - the near fields usually have a low end boost that becomes tooo strong when flush mounted. It depends on the availability of low end controls on the speaker.

the sae site explains that you build a tight box around the speaker

The idea is to make the soffit frame rigid. The speaker front becomes extended by the front surface of the soffit mount. I recommended making the plane below the speaker dead acoustically to stop thoses pesky reflections off the rear of the console.

where do the cables for the monitors go?

you drill holes for them , put the cable through, then seal it up again.

how do you prevent overheating?

for powered monitors you have to create an airflow that comes in through the bottom port - through the trap and then out the top above the speaker close to the ceiling.

thank you so much for your response. very helpful. i guess the question that remains is:

if i shouldn't flush-mount my nearfields, where should i place them instead? the diagram on the sae site shows the bass frequency reflections off the back wall creating a lot of acoustic chaos. Is this solved with bass traps and absorbtion materials? Should I place my monitors on stands at a particular distance from the back and side walls? Thanks again, John.

cable way

is it possible to connect a pvc pipe with a speaker box or it will defeat the purpose ?
