"The addition of XXLT and XLTs made a substantial difference to the detail and opening up sound staging. However, addition of RTDFS took it to another level. I will equate to the difference between watching 1080p and 4K TV, or watching through a clean window, and then again after you clean it with windex. The instruments and soundstage is now not only more detailed but sound is clearer, better defined and more 3D. Highly recommended."

It's been a blast this last year tuning in some of your systems. To answer the common question on the RT products, instead of me promoting our pages let me point you to one of our dealers this time. Many of you use Music Direct as your source so here is our page there http://www.musicdirect.com/m-348-roomtunes.aspx

You can also go to The Cable Company's page on Acoustics https://www.thecableco.com/Catalog/Acoustic-Treatments and explore some of my designs as well as other acoustical approaches.

This needs updated badly :) but here are some of our tuned systems to get ideas from http://tuneland.techno-zone.net/t249-a-look-at-tunable-systems

As most of you know, I enjoy getting involved with as many private listeners as possible every year. For those getting started in tuning your room I recommend us going through your system and seeing how it is mating up with your rooms virtues before going too far into the compulsive buying mode (we all do it right). I (after looking at your room) usually point you to the upper corners of the room. For those new, see those triangular pillows up in many audiophile gallery pictures? Those are called the CornerTune http://tuneland.techno-zone.net/t57-roomtune-acoustical-treatment . The CornerTune or other upper corner treatments are the most common starting place. Why? About 95% of audiophile rooms have upper corner loading taking place. How do you know? Walk up to any corner in your house, point your head into the corner and talk. Hear that loading? This in most cases (depending on room build) is the single biggest factor in what your music sounds like. Your room after all is your speaker. You can't separate your system from your acoustical space, they are one. If your in that room and the speakers are in that room, that room is what your hearing. Why? Our rooms are the biggest acoustical source. Let's make it even more simple. Look at the size of your speakers, now look at the size of your room. Your space is bigger than your speakers right? Both are acoustical machines, which one is bigger?

A lot of audiophiles try to put the speaker ahead of the room in the acoustical chain, but this really makes no sense. If your ears are in the room, and your speakers are in the room, look at the common denominator "in the room". There's not an in-room system on the planet that is minus the room. Even anechoic chambers all "sound" different. I doubt that many of you listen in an anechoic chamber anyway :) . That would be a little silly.

So, go ahead and walk around your house and pay attention to the acoustical loading areas in your room and even your house. You'll notice while walking and talking that not only does every room sound different, but every room "feels" different. This is because (among other reasons) you are walking into different pressurized zones as you go from one place to the next. Having a hard time feeling this? Take a minute and walk in and out of your house. Go from inside to outside and back and you will hear and feel the pressure. You may not have paid attention before, but go ahead and experience how huge of a difference it is from one type of space to the next. Also while doing this pay attention to how your voice changes and chest feels when walking from inside to outside and back. Surprised? Notice that when you are outside you push your muscles more and when inside the whole room fills with energy usually without having to push at all. The less furniture the less it takes for you to be heard and the easier it is on your vocal muscles. The exact same thing happens with your stereo speakers. Too much furniture and the drivers have to push harder. The harder they push the less coherent they are. On the flip side, if you let the room run wild in most cases you will have conflicts between the pressure in the room and soundwaves.

This is way I have developed the system of room-tuning and why this forum calls this Room Tuning. Room tuning is exactly the right word for what we do as audiophiles with our rooms. Whether you stop at speaker placement or you go full control with something like our PZC's (Pressure Zone Controllers) the interaction between your speakers and your room and your ears is the whole acoustical ball game. Your not going to play ball without the field and your not going to have the best of sound without putting your acoustics in-tune.

So first step is to find the major loading (recommend looking at where the wall meets wall meets ceiling). And then we move on to the next placement.

After the corners are in place, start looking for the next loudest loading. Be careful not to over do. It's easy to dampen music content while voicing your room. Once I get up the CornerTunes I reach for the EchoTunes or RT Squares. Here's a video if you want the simple short cute version https://www.youtube.com/watch?v=rufEnsVR_eE

....basic acoustical intersections and main corners in most homes is where you are going to want to treat before moving on to your serious soundstaging room-tuning. Look at our room diagrams to see where these areas are again.

There are a few different companies to look at and try and here are some tips that might be of help for those who have done the others but still find things missing in the sound or end up with a dull sounding room. I like barricade products a lot better than direct absorption. I also like room voicing tools like these http://tuneland.techno-zone.net/t76-mga-sound-shutters-acoustical-defuse-aeroplanes . RoomTune covers the whole range of products from treatments to the construction http://tuneland.techno-zone.net/t75-the-tunable-room-s-a-m-walls so there aren't many tricks we have missed, but here's the important thing. Your room is unique in it's design construction and sound. For this reason we have designed a few different types of designs to use together in shaping the acoustics as well as physical pitch control.

In the end game of this sport of listening it all comes down to methods of listening and tying you, your room, system and recordings into each other. Treating your system as a whole is the only way to get to that higher end in listening. For us MGA/RoomTune we design the speakers, acoustics, mechanics and the rooms. Everything from your circuit panel to your ears we do variable products and methods for. We start off with the RT Pillows all the way through the PZC, which is a variable treatment that you tune in with a key, and on to the tunable room itself.

Hi Listeners

Thanks for your emails and calls over the last year. We have been working on making the "method of tuning" more informative for those new to fine tuning their systems. We now have in place a new website that we will be continuing to build, showing a practical application approach to the art of listening.

We're very happy so many of our past friends have visited with us and so many new friends have joined the fun. It's only going to get better as we are doing more shows, both for our designer friends and show rooms of our own to demo. We are investing more in IT with the hopes that audiophiles will have interactive sites supporting real time "doing" of the hobby.

It's exciting to see this hobby moving forward, and for us, seeing it becoming far more variable. As the hobby moves from "one sound" systems to "tunable" we invite you to experiment and share your personal system setups and evolving practices. These are great times for listeners!

Thank you members!

We are continuing our work on the different websites and appreciate your input. Here is the RoomTune page http://www.michaelgreenaudio.net/#!roomtune/o9d9x asked for. This page gives you the basics on the product.

Your emails have been wonderful and it has been our privilege getting you tuned up. The funs just beginning and the more you get into tuning the further we will go in designing our websites to make getting tuned easier. Keep those cards and letters coming friends!

Hi Allen

Thanks, it's my pleasure! I've been wanting to spend time sharing more but for some reason my posts have been getting deleted. I take this as a hint my thoughts on certain subjects may not be welcome here as much as I would like them to be, even though many here have encouraged me to do more writing as well as more promoting of products (both mine and others) I have been talking about throughout the industry in the effort to expand the method of tuning.

I don't mind taking a hint and will do what I can to promote tuning within the wishes of the mods here. The way I look at it is, I appreciate that the forum here (and other forums and industry folks) allow us and others to give our web addresses and links to others in this hobby who we work with and enjoy sharing.

As wide open as this industry has become on some issues, other issues tend to move slower as far as protocols. All in all what I see is the hobby and industry as a whole evolving to a place of reaching each other in ways that are different than the days of internet trolling and negativity. It's getting better every day and that's the important thing.

I do believe forums are going to be one of the keys to the expansion of our hobby and as sites become "friendly sites", as some are starting to promote the community of high and audio will go through a type of renaissance, that will focus more on "can do" instead of can't. This is taking place very quickly which is a great thing.

So as we do on TuneLand we look forward to sharing more and more in ways that promote the good of the entire hobby.

I was sad to see the forum on The Absolute Sound close but hope that in time it will reopen. Maybe closing is a sign of death in order to be reborn into a new vision. "behold all things become new" type of thing.

Hi Allen, good to see you. I'll check out your other posts to see what you've been listening to lately. The Rev speaker production has taken up most of my time this summer and still. TuneLand Vegas has stayed busy so that has put a lot of my posting on hold, except for quickies on Facebook.

hope you had a great summer of listening!

It was a busy couple of weeks after the event. It was surprising to see so many folks displaced after the shooting. We as neighborhoods got together and helped kick in, such a great town! We love our friends and visitors. Vegas sometimes has this bad reputation, but it really is a city of love.

I've been writing about the Audolici AP-01 preamp this last week and some of the music I've been enjoying with it. check it out http://tuneland.techno-zone.net/t414-mg-reviews-the-audolici-ap-01-preamplifier#8175

Also speaking of Room Tuning you might find this fun, a new Tunable Room in Malaysia http://tuneland.techno-zone.net/t404-my-tunable-room-tjbhuler

take care my friend, and have a great thanksgiving
