Floating floor over basement concrete. (Artifact Recording)

Got more... The second and third pic down, I've hung the supports for the bass hangers...

And the entire front wall and center stand...

Great pix! Thanks for sharing! I'm sure you're heartbroken with all the real estate you're losing with the bass traps and such, now that you can see that first hand.

Ehh... Somewhat. But then again, depends which way you look at it. :roll:

OK, latest update... Front soffit wall is nearly complete. All the insulation is in place. Just need to put the 2 layers of plywood on the front, and it's ready to rock -n- roll except the treatment on the front which will happen later... It's lookin' pretty darn cool... :D :D :D :D :D :mrgreen:

Another update... First layer of 3/4" ply is up. I finished off another roll of film. Hope to have more pix either today or tomorrow... :mrgreen:

Aaronw, I have been following your project for two days and I think you are doing a great job, congratukations!!!!! I'm new on this forum and it's my first posting. I don't understand why did you build the bass traps in that way?? I mean, why did you make the holes facing to the center?? Thankssss Pablo 8)

I don't understand why did you build the bass traps in that way?? I mean, why did you make the holes facing to the center??

Are you referring to the front soffit wall? Or something else? Here's an update. I finished half of the second layer last night on the front soffit wall. Sorry for no pix yet...no $$ to develop. :( Now that I am approaching the "Finishing" of the room, I've had some time to reflect on some potentially challenging issues ahead, as well as some possible design flaws (such as...when drawing to scale, allow for finishing materials!!! :roll: :shock: :? :oops: ) And...It's looking more and more like I'm going to lose the existing setup for the equipment rack. I'm going to insulate it, close it up and seal it. I'll make 2 separate racks to sit on the sides below the rear soffit sections. Reason being for moving the rack...just not enough elbow room. The problem is, once it's in, it's in the way. Especially once I purchase a 2" machine. Not enough room to wheel around it...(just a minor design flaw) :oops: Well...this is my first studio, and I expected some design errors. Now it'll be down to how it ends up sounding after treatment. Wish me luck. :wink:

Questions about the bass trap: Why did you build it behind the soffit wall??? Where it is supossed the air gets into the bass trap?? Did you calculate the size of the bas trap windows?? English is my second language, sorry about my mistakes. Best, Pablo 8)

Why did you build it behind the soffit wall???

I'm utilizing the "space" behind the soffit wall also as a bass trap. When you soffit, the left & right soffit sections are angled at 30 degrees. And from everything I've researched here, that extra space is good to use for bass trapping.

Where it is supossed the air gets into the bass trap??

I will have vents at both the bottom and top. This will serve as a dual function. One, for the bass to enter, two, for the powered monitors to breath (let the heat out).

Did you calculate the size of the bas trap windows??

No. I'm going based on some other info John had posted on this forum. And hanging on by the seat of my pants... :lol: The bass trap in the corner, I will have access to if changes or adjustments are needed for tuning. I still have two rears to finish building as well.

I've hung the supports for the bass hangers...

:shock: :? Are YOU sure these actually work. If so, can you tell me what makes you sure. fitZ

Are you referring to the cross braces along the top of the framing, so I would have something to hang the hangers from. That's what I was referring to. I do know, that entire front wall is solid as a rock, and it's floating away from the walls and ceiling. It's not going anywhere. Now, the back soffits... I'm :? about. It's going to be quite the challenge to support them freely. Time to get intricate.

Hello Aaronw. No, I was referring to the hangers themselves. At the risk of being accused of heresy around here, I asked this to find out exactly what it is you base your trust in. As far as I can tell, there is nothing posted anywhere that illustrates the principle by which these "hangers" work, nor any lab results using these hangers as the subject of interest in a manner which they are used. I only pursue this as a matter of my own project . It seems in the course of designing my own little one room studio, I have altered my previous design, to make use a very large closet within the rear wall. This closet is close to 11 feet wide, 3 feet deep and full height. My original design was centered around the use of this closet as a soffeted Analog Tape Machine enclosure, as I have 4 R2R's with a steel rack mount frame the same length as the length of the closet. But then I became aware of the "bass hanger" concept, and the more I thought about it, I became convinced that this closet would be best used as a "bass trap" as it is 3 feet deep. Perfect depth for this type thing(non professional assumption), as I wouldn't have to take up extra room for this application elsewhere. As I prepared to demo some of the existing wall around this closet, such as removing door jambs and the doors(8 louvered) to widen the opening to the width of the closet itself, I came across a discussion of the "bass hanger" principle and application which rather disturbed me. I own my home, and can do what ever I please to it. But arbitrary demo and constuction based on a concept that MAY not work, would REALLY P--S ME OFF, were I to discover at a later date, that this concept had no scientific acoustical proof of performance. I just hate building things that take time and money based on trust in the information that may indeed be incorrect, but because of propagation on the net, may have arbitrarily become "net fact". Aaron, I am at most, a layman in regards to acoustics, but interested no less in knowing that what ever I invest in time and money is not wasted on things that are.....lets just say "possibly flawed". Doesn't that make sense? Anyway, I also happened to come across this point in your thread, and figured since you had come this far, maybe you could point me to some data that you were basing your trust in the performance of this concept on. I dunno, maybe you just trust things arbitrarily. Thanks for the reply.

I think Rick is referring to this thread - http://forum.studiotips.com/viewtopic.p ... 9e607782a9 Rick, if you'll combine my comments on the first page (my second post) with Eric's on the third page (Posted: Mon Apr 11, 2005 3:21 am - specifically his comments about testing WITH and WITHOUT) you may find a way to conduct your OWN experiment, without the risk of building something that's a total washout. (i.e. build the trap with provision for removable front [screws, foam weatherstripping] and a method of hanging the hangers [lag hooks??] - then, once you're at a point where you're ready for testing, we can set up a time when I can "shoot the room" using ETF - we can also do pix, and post the whole thing for all to mis-interpret :? I would use 3-4" (not 3/4") of either 703 or Ruxul AFB across the FRONT of the closet, and line the walls with the same; the intervening space should be set up with supports for hangers spaced in a herringbone pattern \\\\////, with enough space between hangers so that the FLUFFY insulation taped to the hangers themselves just touches a bit from hanger to hanger - If things are tight, I'll even pop for the 5/8 particle board in the interest of science/knowledge; I'd go with 2' wide, almost touching at floor and ceiling, and angled 30-45 degrees (basically, whatever fits between your front and back 4" batts or at least 30 degrees, hung to clear the front (outer) batts by about 2" - Granted, this won't "put it to bed" completely, because it will be only ONE example. However, having a closet like yours seems to be fairly common in a lot of houses, so this could be a pretty useful real-world experiment with quantifiable results (sorta) - If you're up for this, so am I; it's just a matter of scheduling as far as I'm concerned. As to your concerns about "internet fact" - I know John has done these in several rooms, and he tends to use his EARS as any good engineer does. 2 of the Aussie equivalent of Grammies tends to make me pay attention to what he says, in lieu of personal experience with hangers (yet another reason for our "experiment", right?) However, I also know that we tend to think of anything below about 200 hZ as "bass", and a surplus of 100-150 hZ makes a mix sound really bottom-heavy - so maybe that's what gets "sucked up" more with hangers, rather than the "sub bass" range that hangers have reportedly NOT helped - again, your closet/labor + my testing = Our possible edification... Steve

There's another guy here in town that just moved from the LA area and is building a studio. His drawings also include bass hangers in the drawings for his last studio as well as this one, so I would think that this is a standard practice. Now, for the exciting stuff... I started putting down the Pergo flooring yesterday in the CR. Yippie!!! It's lookin' good. BTW...I'm having a party on the 23rd. If there's anyone here that's local to Nashville, drop me an email, and I can give specifics if you're interested in stopping by. :D

I think Rick is referring to this thread -

You got it Steve. Can't sneak anything past you huh? :wink: In regards to my own project, I'll be starting on it in about a month. Give or take honey do's etc. AND my new occupation. Ha. I could get sent to another city for a few months at a time, so that might deter the best laid plans even futher.. In regards to that thread, I've got to re read that whole thread, among others, in context, cause something still is eating at my craw. Haven't put it into final format yet, but something is just not ....well lets just say kosher. I dunno. But I'll get to the bottom of it yet. Just haven't got all the facts straight. In the meantime, please understand my motive here. Ether things are, or they arn't. Plain and simple. If grey areas are ok for some, they better be ok for everyone. Otherwise its bull. As to my questions there, I'm a layman, and Eric knows it. He WOULDN"T have gone to that length if I hadn't touched a nerve. And sorry to drag my curiosity over here, but I follow the smoke to find the fire. That being said, yea Steve, I'd love to follow you up on that proposal. Give me some time to get some crap out of the way first though. Then I'll really jump on it. I like the herringbone idea too. You read my mind. Anyway, thanks for the offer. I'll put my ...ahem, curiosity to rest one of these days. Maybe when the shovel pats my face. :lol: Aaron, sorry for imposing on your thread. I was just curious, thats all. Thanks again Steve. Rick :)

Cool; I didn't see a prob temporarily "hijacking", since Aaron's also doing hangers; I figured he might wanna think about doing the same experiment - (Or, Aaron, are you so freakin' burnt out on hammer-bang crap you just wanna BLAST ??!? Steve

I know I'm ready to start playing w/ my toys again. Can't wait until this control room is finished. Here's the latest...The control room floor is nearly complete. Only have about 4 1/2 rows left to lay down, and it will be finished. IT LOOKS GREAT!!! Things left to do (for Control Room & Iso Room): Rear Soffits: -Frame -Stands -Bass hangers -Insulate -Electrical (lighting & outlets) pull wire & terminate -Ply on front Rear Wall: -Frame for acoustic treatment & support for ceiling frame for treatment -Absorbers, diffusors -HVAC stuff -Frame window to ISO booth -Measure, order and install glass -703 & Fabric Front Wall: -Finish 2nd layer plywood -Cut vents that I forgot to cut prior to hanging plywood :oops: -Lower half...703 & Fabric -Top half build custom reversable panels (Reflective on one side, absorption on the other) -Install mounts for LCD or Plasma displays -Pull low voltage lines for monitors, video, etc. Ceiling: -Frame for custom built 703 & Fabric panels -Install lighting, pull wire & terminate. Right Wall (to live room): -Frame window -Measure, order & install glass window -Install acoustical materials (choice unknown until I go to tune the room) Left Wall (to outside): -Frame windows -Measure, order & install glass windows -Install acoustical materials (choice unknown until I go to tune the room) Other: -Finish ceiling in first sound lock -build ramp in sound lock up to control room floor level -Frame door jams -Sand, stain and treat doors for control room -Seals for doors -Frame large bay window in Iso room -Measure, order & install glass for bay window (big bas*ard) -Build bass traps & finish acoustical treatments for Iso room -Frame door to electrical room -Install Solid core door (stain & treat too) to electrical room And the list goes on...

Sooo, in your spare time you're gonna join a book club??!?

Spare time??? What the heck is that? It hasn't been a part of my vocabulary let alone reality in nearly 2 years...

OK...good news...The control room floor is complete. Lookin' great. I hope to accomplish more over the weekend. Monday is my B-day, so I'm taking a 3 day weekend and taking next Thursday & Friday off before the party to do as much as I can. I hope to have the rear soffit walls done and finish the front. Possibly move the console into the control room??? (A big maybe). Gotta run...Everyone have a good weekend. :D

Happy B-Day man, be sure and stay away from that wild pussy (your hand will thank you :lol:

:lol: For those who don't get the pun... :lol:

Pun hell, thats good advice no matter :wink: BTW Aaron Happy B-day!!

Thanks everyone. Had a great B-day. Went and had dinner (it took 'em almost an hour to serve the food, so they comp'd the whole thing... :) ) Then my friend took me to the strip club (yeah...different Pu$$y this time). Got hammered (still recovering today) and hugged the porcelin throne :roll: . OK, here's the latest update from the weekend. Finished the second layer of plywood on the front wall. Terminated all the electrical for the front wall in the panel. Front wall now has juice. 8) Placed my speakers in the front wall (Holy crap!!! It's amazing the difference in sound now. The boom boom is gone (of course I still need to bring my sub down there). Those traps are working great!! Started the wood frame for the 703 & fabric on the lower front wall. Measuring out for the Bezels, etc.
