It's around 9ft x 9ft. They seem good, I'm happy to go with them, but they said that "it will be hard to get frequencies below 70Hz in here." Is it this simple? It's a big investment for us. I have to place a lot of trust in whoever takes on the job. I came across a discussion on stereophile.com from 2014, on bass in small rooms. One of the members, a guy called Michael Green, posted this: My one listening room is 9 X 9 and easily goes into the twenties no problem. Keep in mind sound is vibration, and if the room is not able to reproduce vibrations your not going to hear them. Also if you dampen the room to the point where you are only hearing what's coming off of the cone that's exactly what the music will sound like, "a cone" and the body of the musical notes will not be fully developed. For many years I have had to go in and rebuild rooms that were extremely over built. It's an embarrassment for the client to spend all that money to only find that what they ended up with was frequencies and not music reproduction. You will get sound below 70Hz no problem. The issue you will have is that the room modes will be quite high in frequency in small room. You can download some free software called REW which can simulate the room response and take measurements if you get a microphone as @recernext mentioned above. here is you room, I guessed 8ft ceiling height and speaker/listening position. Another issue is that as your room has the same width and length dimensions those 2 room modes are at the same frequency. So you get a big amplification at around 60Hz. The bass will just sound boomy and one note as a result. This is followed by a cancellation at about 80Hz. In a simple shaped room the simulator is fairly accurate but its always best to measure to see what you really have. Corner treatments can help with this, but they will ideally need to be the tuned membrane type to coincide with the room modes. They can be quite large and impractical in a small room. Be wary of just foam types, they wont work well as they would need to be massively deep to absorb the long wavelength. Other option is of course equalisation which will notch down the offending resonances. This can certainly work, but wont deal with the cancellations. Hope that helps a bit.
