GIK acoustic panels


Just installed some GIK bass traps in the room corners today and instantly solved the "sonic boom" that was happening around 35hz.A 2'x4' 244 panel in all four corners did the trick.Easy peasy:)I've got three 242 panels(for reflections) a 7" thick " monster trap ",and 4 2'x2' spot panels to fool around with now.The monster trap is VERY effective.I amused myself moving it around and could easily hear the changes.The front wall behind the speakers is the recommended position but it made the room sound dead, surprisingly.Another surprise was when I propped some panels in front of the two large windows in the room - no change at all.
So next up is getting them at the wall/ceiling junction and possibly on the ceiling without having a zillion nail holes to fill later.The panels all come with eyehooks and picture wire to hang them up.Good thing the room is not too big.16x17 cube unfortunately,so it needs a little help.I'll post the final results in a few days for those of you who are curious like I have been but hesitant.

No worries.The new speakers have more bass energy and just needed to tame a 'thump' in my (unfortunately) square room.The thump is banished.Just experimenting with fine tuning now.

Or, maybe you guys should get the original upper corner treatment and kick back and listen to your recordings for the first time "RoomTuned" :)

It's nice to see so many coming full circle and back to the original treatment that got it all started to begin with. (Brag with a bit of fun promotion).

So easy to tune the room with RoomTune, your speakers, your room and your ears. And, so fun to tune your room with other RoomTune folks (Tunees). I love square rooms, or any room as far as that goes. Tuning a room is one of the most exciting adventures a listener can have. In the last several years, removing other folks products and seeing RoomTune go in, or even back in, has been a blast.

Want to step it up a few notches? Make it variable.

Want to get any sound you want? Do a full Tunable system.

I'm working on the updated site now to walk any audiophile through making your systems completely Tunable. In the meantime you can visit us at TuneLand and watch your fellow Agon members get Tuned up, all the way to the Tunable Room.

So nice to have the hobby go Tunable! So nice to see folks get to their dream sound!

Michael your spot treatments are very attractive aesthetically and I understand how treating the reflection points precisely could be effective.The hard surface of the wood seems counterintuitive though.Shouldn't the wood be a diffusion panel?

Hi jtcf

I make several types of acoustical/mechanical designs. The first one introduced was the RoomTune pillow product. RT is a two sided pillow, one side burn and one side live. In almost all cases the "live" side faces the room while the "burn" side faces the wall.

Next was the RoomTune Deluxe which allows listeners to zone their room. Still live side burn side. The live side faces the listener in most cases and the burn side acts as an acoustical barricade, or stop sign, for the unwanted pressure. The RTD became the standard for floorstanding tuning and that’s when "pressure zoning" took off, replacing LEDE. RT floorstanding products started what was called by TAS the "Tuning Revolution" which sent me around the world introducing folks to a more involved way of listening.

At that time I presented three concepts that better explained how the room works for the listener. One is "Laminar Flow", next "Corner and Seam Loading Control" and third "Pressure Zones", and gave the hobby a new term "RoomTuning". The thing to keep in mind is at that time we didn’t have the internet, so the talking about these types of things were done through the magazines.

There were 3 acoustical guys back then (besides killing the sound products like Sonex). One was ASC "trapping", second RPG "defusing" and RoomTune "tuning". If you look through the Michael Green’s "TuneLand" forum you’ll find a blend of products, RoomTune, PZC, SoundShutters, all the way up to an actual "Tunable Room".

With the PZC specifically, it is a Pressure Zone Controller, a tunable barricade system that replaces the sound coming off of the room’s structure. Before the room’s loading has a chance to activate the PZC grabs the energy and converts it to two things. One is the acoustical pressure and the other is the mechanical vibratory structure of energy. If you walk into a "Tuned" room it literally is "In-tune". At that point there is no need for trapping the energy. If there is any need in that department I make something called the Pressure Box, which set in the right place takes care of any extra in-room loading still going on. As far as the need for defusing in a Tuned Room, there is none because the sound pressure is now working with the speakers and the room not against each other.

RoomTuning and Tuning in general (Tunable speakers, electronics and all the tuning toys) is about restoring music not distorting. With the PZC’s being wood in the front, look at the Tuning Bolt. When you adjust these you re-voice the mechanical/acoustical interaction, exactly like what you are doing with a guitar, drum, piano or any other acoustical instrument. In other words what I do is turn your room and system into a musical instrument, instead of energies fighting each other they are tuned to work together.

Michael I do remember seeing your products way back when:)You actually inspired me to experiment with 'tuning'the speakers I owned at the time to dampen and tighten up the bass.I also made some pillows and thumb tacked them in the alcove behind the speakers in our former house to good effect.
You have some interesting products and theories and thank you for posting more about them.

Another thing that I find fascinating is how way back in time how jugs filled with different levels of sand and stones were used as acoustic treatments in amphitheaters.Then there are the old churches,theaters,etc. that sound amazing and perfect.Acoustic perfection to me is my aural memory of concerts at the old Fox Theater in Detroit.
