Floating floor over basement concrete. (Artifact Recording)

"a solid wall insulated, and plywood between the 3 sections, plus the bass trap section on the left side. " - depends - if the wall behind the plasma "wannabe" is part of your mass-air-mass envelope, attaching anything internal to that and the floor will weaken isolation (not sure how much) - but, if you frame without touching the outer wall, and attach plywood to the frame, and fasten solid to the floor and front panel, that would help brace things. Also, since left, center and right sections meet at angles, they would be supporting each other at those joints. It's mainly at the outer edge of the speaker soffits that would be the problem of tipping over by twisting that wall section. One possible way to keep this from happening is to build a cage inside the soffit/trap area, resting joists on top to hang your bass hangers on - if you were to build that cage as I marked up your drawing, it would brace the soffit AND support joists for hangers - Keep in mind that I'm talking from THEORY here, with a fair amount of NON-studio building experience - John may have something much simpler that he's actually built and tested... Steve

Hi Steve, I understood the frame portion for the hangers. But at the same time, trying to figure out structure/construction method in which the soffit wall will stay put since I will not be able to attach the floatedwalls/ceiling that's on RC according to your earlier post. I have another question that popped up during reading the post on soffits. Would you be so kind as to distinguish the difference between: Baffle, baffle extension, soffit, soffit box, flush mount, bezel, speaker box baffle, extended soffit baffle, soffit face, etc. Using all the different terms, I haven't a clue what you were really describing. :? :? :? :? As far as the

plasma "wannabe"

The company I work for...we're dealers for video too. (Although plasmas are still pricy as a dealer). We just unloaded a 50" viewsonic today for a client. What a beauty. Aaron

"Baffle, baffle extension, soffit, soffit box, flush mount, bezel, speaker box baffle, extended soffit baffle, soffit face, etc" - Baffle, Speaker box baffle, both refer to the front surface of a box speaker, where the holes are filled with speaker drivers. Soffit box refers to the built-in box in a flush mount system, where you slide your speakers into. Soffit and Flush Mount, when referring to speakers (not lights) are the same thing - normally refers to the entire construction for flush mounting of speakers. Bezel is a term used normally in jewelry and watches, refers to a part that surrounds another part - in flush mounting, it's the piece Thomas showed in "clear" material, that you would make specifically for different speakers to fit snugly in the same wall. Kind of a "mounting ring", or a spacer. Extended soffit baffle - the face of a soffit, held flush with the face of the speaker, that extends the effective size of the speaker's front baffle in order to force the driver into "half space" radiation. This happens when the flat surface the driver is aligned with is too big to allow the lower frequencies to "wrap around", so they must radiate only in the forward hemisphere. Soffit face - refers to the exact plane on the face of a flush mount system, which should align exactly with the same plane of the speaker being mounted. Did I miss any?

Hmmm. OK. Didn't mean to sound like an idiot when I posted that question. Some I knew, some I didn't. Some sounded like the same thing. Just wanted to clarify for myself and others reading this post. Thanks. In the previous post you made, it would make since that because the front walls are angled, that it would help support the soffit wall. Still kind of unsure about that somewhat, especially if all the weight is on top. Looking at Johns soffit design, it appears the bottom half is only something like 703 covered in cloth. Or is there something in front of it(plywood or mdf)? I'll try and post a drawing when I have time to draw it up. Thanks again, Aaron

Well, just went and listened to the JBL LSR6300 series monitors in a 5.1 setup over at Oceanway Studios. The new features w/ RMC (room mode correction) is a pretty cool feature. The room had a 53 Hz spike, and w/ a small adjustment, voila...corrected. Much more variable for tuning in the monitors for you room. I have the original LSR 28's, so I was familiar w/ the sound, but the RMC, sure cleaned up the sound. May have to crossgrade over to these when my room get's finished here soon. Hmmm...still don't know if I'm going to attempt soffit mounting my LSR's though?? I may just put them on stands, and only soffit mount for 2 mix applications a different monitor? Any affordable ideas? Aaron

Nah, everything I want costs more than I'll earn before I die :cry: Kinda thinking along the same lines for my next place tho, passive surround(on stands) /active sub/high end (Denon) receiver for surround, soffited mains (nothing picked yet, just want $20k speakers for $400 each) - I figure if I don't do my homework in isolation and acoustics first I'm wasting whatever I spend on speakers/mics, etc, so it'll be awhile... Steve

Hey Steve, I used to think that way. But I'm too damn determined these days. (Somewhat anyway). I know I can do anything I put my mind to. There will be a day when I have that nice Neve room, or API, or ??? There will be a day when that Grammy sits on top of the fireplace mantle. (whenever I get a fireplace :lol: ) As you've seen from construction I've done already, I never expected to have ever done something like this by myself. (98.9% of it anyway). It's been a challenge, but I also wouldn't have gotten this far without the help of you, John, and everyone else here on the forum. :D Aaron

Hey, I didn't say I was smart enough to give up, just (somewhat) aware of the difficulties... :? (Must come with being a Taurus... :=) Steve

:) I didn't mean it that way... BTW, Aries over here. B-day is this weekend. Having a party Saturday, so I get to show everyone how the studio's coming along. Well, just got a quote from the AC guy to redo the duct work in the basement for the existing unit...$1400.00 I don't know if that's good or bad just for doing ducts. Maybe this includes the automated dampers and extra thermostats for each room?? (doubtful) I'll have to check w/ them.

OK, finally got these darn pix developed. Let's go back in time, and I'll fill in some of the blanks on the floor. Then I'll post some additional wall pix and the mount. Here we go...

Here's more w/ the insulation...just before the subfloor...

Here we've got the first layer already on, adding the second layer. Notice I marked the first layer of where NOT to screw...

Now we have the walls... They went up pretty quick...

You can see where I put hat channel on the back side of the framing to help hold the insulation in. Also now have the left side and back wall framed... Starting to insulate the front wall...

Now we've got the front and side walls insulated, and the RC1 mounted...

Here, you can see the mount idea that Steve posted on this thread. The only thing I didn't do was trim the metal that hangs down around the stud (track). I wish I had, but I didn't have a chop saw, and the hack saw just wasn't hackin' it.

Now we have drywall going up, and what I did to dampen the drywall with strips of insulation tucked in between the RC...

That's all I got developed for now. Just shot another roll over the weekend w/ the second layer of drywall, and the soffit around the beam covered. I'll post when I get them developed... Aaron

I've got one heck of an AC thread starting over at RO. Those of you interested, here's the link: http://www.recording.org/postt17684.html Thanks everyone, Aaron

I added this link over in the Design forum, but thought I would post it here too... Some great info on Guidlines & Recommendations for Surround Sound production. There are several diagrams showing speaker layouts, etc. http://www.grammy.org/pe_wing/5_1_Rec.pdf Aaron

OK, I've got another floor question. I'm not to this point yet, will be eventually. Hardwood floor in the control room... Let's say I use the Pergo laminate flooring. The stuff I've looked at is "glueless". Any suggestions or recommendations as to how to attach this "glueless" Pergo to the cover plate to where all the cables come up to the console? And what about the floor around the cut out area? How do I keep this down? Or should I go w/ a glue down version of the Pergo? Any thoughts? Thanks, Aaron

I've not used either type, but would think gluing might reduce the chances of any rattles or buzzes - it would also simplify your fitment around the console wiring, although the glueless would go in faster - maybe other members have actual experience with this? Steve

my Floor is glued down (I Used subfloor glue) and no rattles are present :) Bryan Giles

I seem to remember someone several months back talking about using the Pergo stuff, as it was glueless, etc. There's a pad that goes under the laminate flooring (between subfloor and laminate floor) which pretty much deadens any vibrations. Just did a browse, Jai has used the Pergo stuff in 2 different studios. Any more thoughts or ideas? thanks, Aaron

The pergo was a consideration. I am gonna use it throughout rest of the facility. Take a look at the higher end line as it comes prepadded. Bryan Giles
