Mike-48 audio-only room, system, and cat

Thanks, Bryan! It does, in part due to your suggestions. Best wishes for success with Sensible Sound Solutions.

Really liking this room... a lot! What kind of subs do you have in the back?

Thanks, Todd. They are JL Audio Fathom F112. I've had them since 2007. They are heavy, but I like them.

Heavy is a subwoofer necessity. If you said “they are super lightweight, but I like them,” the audience would be heading to the exits

Great listening space. That music scale/frequency response chart is a cool addition.

Lovely, but for the love of God, flip one of those diffusor/absorbers so they are mirrored!! Ahhh, it burns!

Now you've done it! I was successfully ignoring that thought for years, but now I can't see anything else!

When I get some spare time, I'll move the mounting wire on one panel, so I can flip it.

Photos coming. . . .

lol. completely missed that!

I flipped one of the GIK Alpha panels to give better symmetry. Not surprisingly, there's no noticeable difference to the sound. This is shot from a different spot than earlier photos, and I've I moved the 2D diffusers on the sidewalls forward to catch the radiation from the Janszens' side-firing tweeters.

Well, they are not QRD type diffusers so the lack of a mirror image wouldn't be that great but still. Just for theory it should be objectively better. Especially with an OB type driver even though they are firing into a full range absorber.

It just looks correct now

Can you remove the windows? lol... just kidding! It really does look great.

OB-type driver meaning open-back? Unusually, the Janszens in the photo are sealed boxes, with electrostatic elements and cone woofers facing the listener and (optional) ring radiators facing the side, the latter run at a low level to provide some airiness to recordings that don't have natural soundstage. There is little radiation to their rear (front of the room), but enough, I guess, that putting diffusion on the front wall killed occasional sonic "glare" in the soprano range.

My whole setup is aimed more at getting the ambiance on the recording, rather than providing a sense of space through local room ambiance.

You're joking, but the ceiling well around the windows resonated a bit like an organ pipe. It's a bit hard to describe, but I had heavy lucite panels made that rest against one edge of the well (the closest one to the listeners) and against the picture rail to close that off, mostly, They can be removed quickly for cleaning, and they're open enough at the sides to allow ventilation when the windows are open.

Is it obvious, I'm a retired person needing something to do in the dark Portland winters?

Sorry. OB is open baffle

Sorry. Thought the main driver was open in the rear

Well, even you can't know every speaker on the market! The Janszens are quite an unusual design -- electrostatic but closed-box -- and their controlled directivity works very well in my room, with its low ceiling and relatively narrow width. They are a great solution for small spaces, and easy to place, the drawback being a rather narrow sweet spot. The side-firing tweeters give the adjacent seats very good sound, too, but without the sharp focus of the central seat.

Easy.me. Mike-48. There are fewer things that have us Audiophiliacs chasing the dream than the truth!!! My limitations sound incredible, even to me based on the source, but at the end of the day, respectfully, I see a lot of peeps commenting on how 'good' your room looks. Who gives a ____ if it looks great, if it sound like ____! To you, if you measured your acoustics, and your wife and children love it, who the ____ cares!!!

Kevin, The thing that matters to me is whether I love listening to music in the room -- and I do. All the work has been to increase enjoyment of the music, both my own enjoyment and the pleasure of those I share it with.

Hi Mike
can you elaborate on the method or procedure you use to align the speakers to the blue tape using a laser thanks

Sure, I have a Leica Disto, which is a laser distance-measuring device (bought when we were shopping for houses). I put that flat on top of the speaker with the angle bracket (orange in photo) holding the Disto perpendicular to the back of the speaker. So when turned on, the laser is aimed straight ahead with regard to the speaker.

I get the laser center side-to-side on the speaker by aligning the angle bracket with a level control that's centered on the back of the speaker. With other speakers, but one could measure and put tape on the back of the speaker to mark the center.

By turning on the beam, I can check that both speakers are raked back the same, and once I have decided on a toe-in angle, I mark the wall with tape & can reset the rake and toe-in if they ever are disturbed.

Does that help?
