I need to make an on wall low profile speaker(concrete wall) What is the lowest profile midrange that is decent?
What does the wall being concrete have to do with anything? No matter what the wall is constructed with has no bearing on how deep a speaker is.
I personally would not make any speaker box less than 5" deep, so most any midrange driver will work.
I mentioned concrete wall as to rule out in-wall suggestions. The speakers need to be about 2" deep for LED TV; that is why I am looking for low profile mids. I am leaning towards these; they are a bit pricey though since I would need 4 drivers per speaker:
Anything else that i should be looking at?
