Dedicated room suggestions

Try out the Room EQ Wizard's room simulator which should help you compare.

Also the AM Acoustics room mode calculator will let you see where the worst modes will be.  Combined they can be great starting points.

Hey @chiadrum , there is a video in the other thread you were just in where Anthony Grimani discusses room treatments. His website is below and they sell both individual treatments as well as kits for entire rooms. I followed the recommendation in the video and got great results. You can see the measurements of my treated room in my system profile. I would definitely e-mail them or call if you like what you see in the video. Anthony corresponded with me via e-mail and was very helpful. If you post some pics of the room it would be better. You need to take into consideration where the windows are, open doorways, etc. Those speakers will likely be better off well into the room.

Thanks for the suggestions guys. I will check out the tools that you mentioned.  Regarding the room layout, the entry door is to the left center of the room while the window is centered on the outer wall. 
When you step in, on your left a small closet will need to be framed to cover some HVAC ductwork. I was thinking about a soundproof window cover and a sound engineer friend of mine recommended an outdoor door as well. 
I snapped some pics but from my phone at least they want a URL to post pics?

My laptop is charging. I’ll try to post pics later. 
 

I should also mention that with certain recordings (only the worst recordings, everything else is fine) with my current setup I am getting some harshness. But my setup is pretty pathetic. The speakers are maybe 4’ apart and I am sitting maybe 8’ away. My new room will allow me to properly space  the speakers and sit much further away if that provides the optimal results

I heard none of that harshness when I demoed the amp and streamer/dac. That was in a large room with the speakers far off the wall and spread apart as Klipsch recommends. Literally listening to the exact same recordings. 
 

You can setup a virtual system in your profile and post pics there. That harshness will likely resolve once you get your room right. Dampening sound around the window is a good idea if is noisy outside. The first thing is to orient your speakers and MLP. The angle is very important. As for which wall to face glass is not acoustic friendly. There are ways to treat windows but if you can keep the window behind or away from the space between you and the speakers its a plus. I know you are doing 2 channel not atmos but this diagram with the angles of the left and right speakers is a good layout:

As for the floor a rug or carpet is not as reflective as hard wood. Also you can use a tape measure to get the distance of each speaker to the MLP to match. Orient the tweeters to ear height if possible. Try and keep the speakers at least two feet out from the wall and then you can test moving them closer or further out to get what you like.

Hi there!

Acoustics and "the room" are one of the most important items to address first when putting a new stereo room together. I've used these folks for both products and detailed information. Top shelf products that work and do what you intended.

Realtraps.com

Excellent resource for anyone interested in acoustics. No affiliation - just a happy customer. 

I decided to use these Real Traps after reading how many professional music people use them. 

Another resource I found that really helped was a book by Jim Smith - Get Better Sound. With these two resources you'll get excellent results if implemented.

Enjoy!

Thanks again. I have some homework to do, at least I’m in the right place :)

For better or worse, my last three listening rooms have  had the speakers & me sitting along (though not actually against, of course) the longer walls. Whether it's mental or actually true, I simply get a larger, wider image, with image depth remaining largely the same. I get better bass balance, as well.

I’m a newbie to the hifi game but based on the recommendation of another much more seasoned audiophile, I contacted GIK Acoustics.  I sent my room dimensions, concerns and pictures and within a few days I was sent back an incredibly detailed analysis with recommendations from a sound engineer regarding speaker placement and treatment options. Analysis didn’t cost a penny, although i was impressed enough to follow through with purchases.  Engineer was very knowledgeable and responsive through the process. 

I have a friend with new Cornwall 4s in a room of the same size only more square

which is worse. Untreated everything sounded horrid. 

The speakers you have are designed to do well against the back wall so  you

have that plus. He added absorbing panels, diffusers, carpet and ceiling treament.

The room went from a hell hole to one with great sound.

Measuring will maximize the sound.

The general rule of thumb is to use the short wall, unless the short wall is so short you can’t get a good equilateral triangle between yourself and the speakers. 

Thanks again all. It will take some time to get the room finished but I will certainly check back in with results when the time comes. This is pretty exciting as my system sounds pretty great now unless the recording is just horrid  i even listened to some tracks from Back In Black last night that sounded pretty darn good now that everything is burning in  I wasn’t hearing that shrill harshness that was present earlier. The current room is a bonus room with the speakers facing the finished wall, and the wall behind the speakers and amp is the half wall for the staircase leading into the room  Initially, simply because I had the tv stand the opposite way, I had the speakers facing that half wall  Simply flipping everything made a large and noticeable difference  I can only imagine an enclosed and properly treated room  

Hi, I have Crites speakers which are about the same dimensions and efficiency  I have been tweeking my system for 3 years.  Slowly and surely I have improved the sound.  My room is 12 × 21.  That is about the minimum width.  Here are some suggestion:

1.  Keep dimensions from sidewall and back wall different.  I  found the center of the speaker to measure during setup.  They are toed in to intersect behind my head. I would not put them against the back wall.  

2.  Room treatments.  Most important are the sidewalls.  I have 2 bass traps but am told a couple more would help.There are several good companies.  

3.  Speaker isolation.  I  bought springs on Amazon.  A very nice improvment.  You can spend much more.

4.  Lower noise floor on streaming system.

5.  It is best to keep equipment behind speakers or somewhere else.

I enjoyed a number of great comments and responses here. I can only add something I saw on Amazon (yuk) of all places. Acoustic curtains. They were VERY inexpensive and SAID to have many good sound enhancing qualities. As an apartment dweller I might look into a couple of those. If y look into their clams they are NOT just for soundproofing and even if they were, the same things that enhance sound proofing are good qualities for SOME sound enhancements in a listening environment.

@chiadrum 

you are new to the game?​​​​​​ Your gear is too serious to be new. :)

You've got great dimensions to start out with. Use the Bolt-area calculator to help.

@grislybutter yeah I pretty much went all in. I have no intention of trying out a thousand different options and obsessing over every nuance, losing 20k in the process. I wanted power, bass, speed, realism. Huge, room filling sound. It's all there in my present system. Now to maximize results :)

I initially thought that I would spend far less, but to my ears the difference between a setup like mine (lower 5 figures) and the 5-10k system was a night and day situation. So I dove in head first. I did get everything at fairly substantial discounts. Cary Audio and their sales are hard to beat. I heard a killer Primaluna amp, but found out that production is in China. That was a no go for me .Especially with the chance to support a business that is 20 minutes from me.

Read this.  It’s the best and most approachable resource on room design I’ve ever read.  I think chapter 11 may be of particular interest to you, but the whole thing is extremely educational and well worth reading.  Best of luck.

Earl Geddes is renowned for his subwoofer integration strategies and bass management. Thanks for posting @soix 

Check page 236 on subwoofer setup, that is exactly how I did it (opposite corners) and you can see the bass response for my subs in the measurements in my profile, it worked great. Earl is the man!

Just had a thought- imagine if everything was as well recorded as Steely Dan or Marcus Miller- this would barely matter :)

I know that's not true but even under far from optimal conditions man do those recordings sound amazing.

@soix , thanks for posting that book, great resource. If it isn't too much trouble could you post your system with a few pics in the virtual system area? Would really enjoy checking it out. Thanks
