Do you use a stand or hold your live mic? The SM7 is a bit bulky and heavy to be handheld, but if you use a stand I see no reason why it couldn't be used live.
Freeway sound walls are made of heavy masonry and do tend to work a little bit for low frequencies, but in all honesty unless you need that kind of heavy fence for other reasons you are most likely better spending your money on beefing up and sealing the house wall.
Keeping it from being heard by the neighbors will be tough and won't affect how things sound inside the room.
You could put an absorbtive panel above the drummer and that will help with the reflected sound from the cymbals but not the original sound.
Your best hopes will be to work with the...
The difference they are charging is fairly little so I would go with 4. You really want to equally absorb the full audible spectrum since whatever isn't deadened will seem exaggerated.
From an accoustic standpoint domes can be fantastic or a complete pain.
In general any concave reflective surface is going to focus all the sound that strikes it at the centerpoint of the curve. If that centerpoint is inside the space any mic positioning in it is going to see a huge peak in...
If you think that your voice would sound better with a condenser then the SP B1 or a Marshall V67 or some of the other choices would make a good upgrade.
If you thought that sticking to a dynamic would be better than saving up longer for a SM7 or an RE20 would be the step up. If you were...
If you have an odd shaped room with lots of corners then look for the longest diagonal measurement, treat one end of that, and then move up top the next.
It isn't the corner that is tha culprit, it is the long column of ari betewen one corner and the opposite corner.
The important thing to remember is that the lowest standing waves in a room occurs between a corner and the diagonally opposite corner. If you think of it there are four such corners:
front upper right to rear lower left
front upper left to rear lower right
rear upper right to front lower left...
Low frequencies are not 'exaggerated' in corners per se.
The volume of air in a room has certain resonances, much like the air in the body of an accoustic guitar.
The lowest resonances wound occur in the longest column of air. What is the longest dimension in a room? It is between one corner...
First of all there is no test data. Without test data you have no idea at all of the kind of foam you are dealing with and what its absorbtive properties are.
Second, even if it were good foam you need at least four inches of foam to get good bass absorbtion. Looking at the six inch width and...
Well as you can clearly tell, the pics say 'Nady' which means low-end, as it your budget. But it also means that unless they are discontinued Nady products you can get then from a variety of audio dealers.
Back to the original question (cable burning...sheesh)
In general do not get cables longer than what you need. The reason is not just economical but that the natural thing to do is to coil up the extra, and that makes it easy to induce hum into a signal.
Here is an example of what one guy did to make properly dense absorbers out of wall-type insulation. As you can see it took quite a bit of work.

The plastic will reflect both high and low frequency waves. There is a chance that the surface might function as a membrane absorber for the bass frequencies, but it is pure guesswork as to what frequency range it will work with.
The target should be three to five pounds per cubic foot. Usually home thermal insulation is shipped packed tightly but also wrapped in shrink plastic to keep it clean and compressed. The plastic will cause the sound to bounce off. That's the balance with absorbers, you want the materials to...
When you consider for just a little more than that price you can buy a whole bale of 703 fiberglass or equal it is clearly not a good deal even if it worked, which I too doubt.
