What are the best Room Accustic Treaments members have found?


I  am looking into adding some room acoustic treatments to my room.  I am just looking for advice on some simple room treatments that fellow members found worthy of purchase.

GIK service and products are very good and competitive.  Keep in mind, they carry NO inventory; everything is made to order.  It’s how they keep their prices down.  My salesman told me today, an order placed today would deliver 2nd week of January, at best.

The suggestion to read up on the subject is a good idea.  GIK has some good You Tube videos.  So does Acoustic Geometry but they’re very expensive.  Lastly, GIK list their suggestions in the order of importance.  If you have the patience, purchase one solution at a time.  I think you will make more cost effective decisions (if you can be patient).

Best investment you can make to maximize your investment.

If you’re looking for simplistic old school acoustic treatment you can do every bit as good as GIK only faster and for a tiny fraction of the cost stretching whatever fabric you like over Owens Corning acoustic panel. In fact if you look at their website they have the exact same OC panels. If paying $1k for $50 worth of room treatment is worth it to avoid having to learn how to use a sheetrock knife, go for it.

GIK is simplistic old school treatment. Next generation and so much more effective you can hardly believe it are Synergistic Research HFT. They make these in different versions designed to go on walls, ceiling, and speakers. Unlike the panels that do very little really, and nothing that like someone already said can be done with furniture (carpet, etc) these things are insanely effective in improving imaging, extension, detail, dynamics, essentially making your speakers, and walls even, disappear.

I’ve done panels, traps, corner tunes, you name it, going back to the 90’s. Actually my 1973 teenage bedroom had egg cartons, functionally identical to GIK just not as pretty. Compared to HFT that stuff is stone age. People I guess are slow to catch on. So you get a lot of advice from people stuck in the 1950’s. Go figure. Free 30 day trial. Which don’t worry, you will not be sending them back.
Plus one for the SR products. They have transformed the sound of my system, or, more correctly perhaps, they have transformed the sound of my room. 
You got your Skyline diffusers. You got your Echo Tunes from Michael Green. You got your Acoustic Discs from Golden Sound. You got your tiny little bowl resonators from Franck Tchang and others. You got your crystals and you got your Mpingo disc from Shun Mook. Don’t shun the Mook! You also got your hand built Helmholtz resonators.
