Those are nice, but remember they are only 12 x 12. The three 24 x 24 panels in my family room are 12 square feet of coverage where this package is 14 square feet. I would think most rooms would need three to four of these packages to get effective results.
You also have to think about how you are going to mount them. I am not a fan of the double-sided foam tape often recommended as it ruins the paint on the wall. The best mounting solution I've ever used for that type of foam was stiff solid wire simple pressed into the drywall and sticking out so the foam can be pressed onto it. The result to the wall is merely a tiny hole where the wire was pressed into it. Two to three wires would easily hold one of those foam panels into place.
And this is what I am talking about for those who have not been in my family room:
The three maroon foam panels perform similarly to the one's @Dentman linked to per square foot of coverage. That entire package is only 14.3% more coverage area. The three foam panels alone, while making an improvement, needed more to truly calm the room. Hence the four diffusor/absorbers above them on the wall. That room is still extremely lively with lots of bright echo and reverb. As such, 14 square feet of coverage is just a start.
No I actually didn't know that. I thought you were only doing speakers. I've been so submerged in the stock market since I jumped in with both feet I've missed a lot. In fact I haven't read any of your recent threads about speakers and such in a while. I've only jumped in here for quick checks/remarks.
That aside now that you officially have a business I would never ask for free services from you. Thank you tough. I'm enjoying a day off from the markets.
Oh i should also mention my brother moved in with us for about 8 weeks while separating from his wife. He left monday to live life in Mexico. I've been very busy and very distracted.
