Building a dedicated 2 channel

invalid

I built a dedicated 2 channel dimensions are 12'4" wide by 20'4" long. I used double 5/8" x board on walls and ceilings with carpet glue in-between the two layers because green glue was just too much money. I built a little bp out on one side of the room for my source and preamp, so it isn't up in-between the speakers. My friend came over with his spectrum analyzer and he said it was the best room he ever measured, you get lucky sometimes. Just thought I would share this with the forum.

Looking good!!

Looks great.

Thanks, I'm terrible at using this site from my phone, I tried to post all the pictures of my room build, but only one showed up for ever post. Plus I don't know how you edit the title so I can add room to it.

Looks like a great space, I like the recess for the gear. Once you go to a full blown two channel setup, in a dedicate room, it doesn't get much better

You ain't kidding, the soundstage is much better, the singer is right in the middle. I have to get the sda2A's TL's in there when my wife is gone, she would miss them from the HT rig if I took them out.

So you used a double thickness of wallboard (x board?). Do you believe that it helps the sound quality inside the room or just reduces the sound that escapes through the walls , ie. soundproofing.

How did your friend use a spectrum analyzer to determine that you have a great room acoustically. Not being skeptical but I seriously want to know how he went about that determination. I have never delved into that myself (yet).

What do you have planned for acoustic material treatments?

Looks nice.

I'm not sure, he knows more about the measurements with a spectrum analyzer than I do. I just know it sounds way better than any room I've ever had a 2 channel setup in.

I haven't thought about room treatments, the Apogee duetta 2 don't really need much room treatments, just the normal furnishings usually do the job is what is said on the apogee forum.

Rooms have walls that reflect sounds unevenly for different frequencies and bass piles up in corners and there are standing waves. It's a very complicated subject that I don't know a heck of a lot about but since you have a blank slate room to play with you'd be selling yourself short to not try some bass traps in the corners and some sound absorptive panels or parametric diffusers, strategically located. I don't believe that any equipment could possibly preclude the need for room treatments. It is called room treatment for a reason.

The potential to increase the clarity and improve the soundstage is huge.

Dipole speakers are different, they don't require as much room treatments. The apogee's are a lot different than most speakers they have a foil woofer as well.

I haven't experienced dipole speakers but to me it is obvious that the more reflections you hear, with different time delays involved, the more unclear or muddy the sound. Have you ever been in a live venue with good seats relative to the stage with unamplified music and experienced less than clear sound? That's room acoustics causing that. You need to try some absorptive panels and try putting them at the first reflection points, whether behind the speakers or on the side walls or both and see if it doesn't clean up the sound. I have no clue what those people on that forum could possibly be claiming that could refute that.

You need to get your learn on about dipole speakers, you definitely don't want anything behind the speakers as the sound coming out the back of them is 180°out of phase with the front to cancel out side reflections.

OK. Enjoy.

I definitely would want some room treatments with my sda2A TL's when I try them out in my new room.

Getting my learn on. This thread seems to indicate a combination of absorption and diffusion behind dipole speakers is of benefit. Absorption in the center of the wall behind them and diffusion (like artificial potted ficus plants etc.) directly behind them. So I'm stickin' to my original statement that you probably need to experiment. That doesn't even address the first reflections (angle of incidence = angle of reflection) of the side walls between the speakers and your listening position. I would experiment with a little absorption there and if you like what you hear add more until you feel the ambiance has been killed, then back off. https://www.audiocircle.com/index.php?topic=38973.0

Most people don't use much if any room treatments with apogee's, plus my room sounds really good and it measured good too.

Gardenstater

That's cool. My buddies and I in my audio club have a running joke amongst us to the point where we want to have T-shirts made up...."It can't possibly sound any better than this". I wish I had $1000 for every time I've said this and heard it said.

I know it can get better, but I don't think the room is the problem, I need a separate dac and a better streamer than just the node2

A more economical option that will still be a nice improvement would be either a Cambridge cxn v2 or 851N from their eBay store...

Seems decent for the money, but I'm going to tuff it out and get something better. I think just getting a separate dac first will make a difference.

We all have lots of areas of improvements that can be made. I don't know where the low hanging fruit is for your system. Since the topic was your new listening room I thought I'd bring up room treatments. They've made a pretty big difference in mine and I haven't even gone past hanging blankets and foam in various places, especially behind my speakers (which are 4ft away from the rear curved or 3 faceted bump out wall) over windows and a door to the right side with a window and in the first reflection areas on left and right.

I might get a few room treatments when I use my sda's in there they will need a few. My apogee's are more critical to placement than room treatments, I have them almost 6' out into the room.

Yes. Send payment of $5000 to me and I’ll ship it tomorrow.
