GIK acoustic panels

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!

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.

Hi Jtcf

The tuning days are coming back strong. I was very surprised to see tuning had drifted so far from what we had started back in the 90’s. In the late 90’s we (MGA RoomTune) had saturated the market and it seemed like Tuning would only grow stronger on it’s own. But then the mom & pop audio stores went under and the magazines had bills to pay, so the emphasis moved back to selling boxes. I wasn’t overly aware of this cause I moved to Nashville to work on studios. I did home audio still but could see HEA was going through some issues and I by myself was not going to make my desires stick in a reviewing market that had their sights on selling extremely over priced products. One reviewer told me this (more than one actually), we have a choice push your Tuning for very little cost or sell $20,000.00 amplifiers. I understood where they were coming from, $400.00 for a TunePak vs $100,000.00 of electronics to the same client. Obviously the $100,000.00 choice by Stereophile was going to keep their lights on. What I didn’t understand was why not do both. That’s when my reviewer friends also gave me that answer. HEA manufacturers didn’t want the Tuning Revolution to take off. At that time I had over 80,000 clients. That means 80,000 people might choose to Tune taking away that many potential sales from equipment designers. That’s a pretty big deal when you think about it.

show & tell

When I started showing the industry that you could Tune a $500.00 amplifier and it would out perform a $25,000.00 one, that made folks pretty darn nervous. The behind the scenes word gets around pretty fast and when I showed up at the CES with a set of Marantz Mono Blocks MA700’s and slaughtered the sound of the rooms on either side, the very first night I had folks in my room telling me this was not going to fly with the "powers that be". The industry thought it their duty to tell me not to build Tunable products. Too late, I had already designed Tunable everything and was getting ready to launch an entire "Method of Tuning" and all the ingredients that goes with that pie. I obviously felt (so did others evidently) that the hobby was about to change from "Fixed" to "Variable". But like I mentioned earlier local stereo stores (650 of whom were RoomTune dealers) started dropping like flies, sadly going out of business before they had a chance to learn how to do their on-line store. There went my network.

It really would have been the perfect time to change things over from Fixed to Variable but the folks at the top of the food chain didn’t want to make the jump. Many of them had found their fortunes and didn’t want to have to start teaching listeners how to tune, is what they decided. More money (for the short term) for them to build bigger toys and less of them, then spend their time with the listeners, showing them how to get great sound and be able to play all of their music collection.

I tested the waters a couple of times to bring Tuning back, but decided it would be much easier to bring Tuning back after HEA ran it’s course and started to run out of gas. Now that things like Class D amplifiers have challenged the expensive guys and the expensive buying revolving door is failing, it’s time to give things another go round. I first started to post on the Stereophile forum but was trolled to death from the start, so I just stayed on TuneLand till I decided to test the waters here. Between here, facebook and TuneLand I’m receiving on average 100 messages a day asking about Tuning or making renewed contact with me. This is a good start and one by one folks are coming over to Tuning or renewing their interest. That’s pretty exciting. I’ve even started talks with Agon so that as more folks get into the Tuning toys again we will find the best way to promote.

I believe the best days of this hobby are still ahead, because I believe listeners are experimenting again beyond just doing the equipment plug and play thing.

nice chatting with you jtcf. thanks for letting me share my thoughts on your thread

I just got back a while ago from doing a RoomTune "Room In A Box" setup here in town. Well I sat on the sofa letting the owner do the work and I guided the placement. It was funny he turned to me after the first RT Square went up "did you hear that?". Of course I've been through this a million times but still :) . He put the next one up and made another comment. It was like watching him eat a steak. When he got done he was pretty freaked out. A buddy of his got there as he had barely put up the last one. The lights had just been turned down and I'm not sure his friend was aware I was coming over. He walks in the room and let out an "Oh God, sounds like a studio in here what did you do". The lights went back up and the look on their faces were priceless. Thought I was going to get a hug. This hobby is so fun when folks get to that acoustical level. It's like watching them become new people. I got out of their way and they started flipping through songs to listen to.

Glad to see you guys having fun!
