Acoustic Room Treatments

Hey thanks for your replies. I have a basic two channel setup with Infinity RS IIb speakers so I definitely need something.

Don’t be afraid you will overdamp the room. A smaller room needs to be controlled. Plus you can always undamp it. if you are serious about this room I highly recommend consulting Jeff at hdacoustics. He is very good with smaller rooms. He designed my room and it turned out fantastic ! Good luck !

“adequate” control is required, overdamping is not recommended as per acoustic consultants who see this commonly

@ghdprentice - did you hire an outside consultant for sonic analysis? I thinking about doing so in my new space.

Get a baseline measurement with REW on a laptop with a decent mic.  Experiment with speaker and listening position first and dial that in.  For early reflection points, try diffusers like curved poly's (easy to diy) if the mid and high room reverberation is mostly controlled, or absorption if the room is too lively.  Also experiment with a mix of both.  Auralex GeoFusers sound nice without any bad habits.  I like them on the ceiling over main listening position and rear wall.  4" of Owens Corning 705 will absorb well down to 80Hz and then drop like a rock below.  Pressure based diaphragmatic absorbers will need to be used for subbass frequencies (50Hz,63Hz, etc.).  Something like the BBC A10 on steroids.  And will have to be large to have enough horsepower to do any good, 3'x3' or 4'x4' each.  Or 4-5 feet thick of velocity based absorption ("pink fluffy" fiberglass).  Welti style multi subs works well for smoothing the low end freq curve compared to a single.  Have fun.

I have a small cube dedicated room, 11.5 x 11.5 x 10.  I have an 8x10 carpet.  GIK is great, but their suggestions for my room were basically to cover the entire room and ceiling with panels at $$$$.  I was so confused about what to do that I have done nothing.  Even within GIK's suggestions, there were many choices of bass traps, diffusion, etc. such that I became paralyzed.  I am going to give them a call and may they can guide me on some basics like the bass traps, and first point reflections.  What I would really like is someone local (in Miami) who will just tell me the specific products that I need for starters and work from there!  Any suggestions?
