Hey,

BTW JB,

You can pick up that roll of Linacoustic RC if you want..........it's down to about 35-45% of roll.

Confirmation eight 2" OC 703 panels arrive Thursday along with Sensa acoustic fabric. I'm painting the inside bay's flat black and will spray paint 703 flat black. In picture I've marked location of channels due to not wanting to put another screw into them.....channels have received enough abuse already!

Plan is to use spray adhesive to sandwich 6 mil poly between two layers. Will hang 4" total absorption panel using picture frame wire to fender washers and eye screws to ceiling. Hoping broadband absorption down to 150-200 Hz.

Front bay will be done Thursday with treatments and fabric. Second row bay will wait until I receive diffusers from Acoustic Frontiers.......hopefully by end of next week.

Am I reading right that you are planning to paint the fabric? Not recommended.

lol Where does it say that? I'm painting Owens Corning 703 rigid fiberglass panels black. Sensa will be in fabric track......and it's black already.

Fred, you had me scared......yup, says 703 gets painted black.

Painting the OC703 will affect the acoustical properties of the insulation. It will reduce the absorption of the high to mid frequencies by reflecting them back to the room. This might be part of the goal here, but should be noted for others. General, I believe this is not recommended.

Though it makes sense ie painting would affect properties, but I've read the opposite. Not saying you are wrong, just might be my resource is incorrect.

Purpose is to absorb high/mids for smoother response. Plan was to lightly spray with rattle can in flat black so treatments won't be seen.

Sensa fabric is really thin and transparent like GOM 701........if I don't lightly spray treatments I suspect rigid 703 will be seen.

Hopefully, I have enough black Anchorage around to wrap if what you suggest is the case.


Edit:

Blldo, you are correct.......don't know what or where I received my info. Maybe that is what Fred was referring to.

Since there's a question, why not try the fabric on the unpainted OC703 and see if you can, well, see it. If you can, then you can worry about painting or otherwise covering it.

Yeah, doing a search here at AVS it's highly recommended NOT to paint 703.

I'll try your suggestion first.......worst case scenario, I can get black muslin at Joanh's and wrap panels, then Sensa into fabric track.

Trying to figure out where I read spaying flat black was ok.........I'm usually pretty anal retentive with planning. Well, mistake averted thanks to Fred and Blldo! Thanks guys......:

Starting to get rack space challenged.......so I've been looking/researching for compact amps that will use minimal rack space.

With addition of possibly 6 more channels to provide power, a traditional amp would require 5-6 more rack units which creates huge problems for me with my 32 ru enclosure.......yeah, should have gone 36-40 ru!

Came across theses amps........

Art SLA2 two channel amp amp provides 300w rms per channel @ 4 ohms......uses 1 ru

Art SLA4 four channel amp provides 140w rms per channel @ 4 ohms.......uses 1 ru





http://artproaudio.com/art_products/studio_amplifiers/


These products sure eliminate a lot of problems.........does anyone have experience or knowledge of these products?

Thanks

How about a Lab Gruppen C 20:8X ? 8x250w @ 8ohms - 2ru.. and each channel pair is bridgable to 500w if needed, have peak limiter (and gain) per channel, remote power on, etc

seems like a good option for future larger atmos installs also (24-32 channels)

Thanks for the heads up! Fore-mentioned solution was three ru's........the Lab Gruppen could cut down ru's to two with a lot more options, besides powers speakers perfectly. Will pay a premium, but am willing to go that route if it simplifies my rack situation. In reality, two would be perfect.......giving me 16 possible channels.

Going into this project, knew I'd have to change my amp situation......

Thanks again......definitely going to consider two of these units.

Nice to see someone mention Swedish amps around here.

"Lab gruppen" Lab is lab. Grupp is group. -en is the. Thus "The lab group".
(So you shoudn't say "The lab gruppen" any more than you'd say "CD disc" )
Afaik they make quite decent PA amps.

Yup, Lab Gruppens are great amps!

I already have a Krell Evo 403, S-1507..........along with ATI 1807 and Halo by Parasound A-31.

If I could sell the pseudo-futuristic habachi microwave oven ie. Evo 403, I could upgrade to my hearts desire. The Krell S-1507 is a great amp and matches Triads real well, but it's silver in color.

I'm definitely not amp challenged.

As far as expanding rack, I could go up but that means opening up a new can of worms. Two Lab Gruppen amps powering 16 speakers while taking up 4 ru's rather than 14 ru's is really enticing don't you think?

Project Battle wounds!



Hopefully, this can be helpful to those who want to clean stains on screen.

Day two back in late June when I was trimming out soffit face, At end of day I notice a small 1" spot on screen......upon further inspection I realized it was pneumatic oil on screen. That morning, I oiled up my 16 gauge finish nailer and didn't realize I had not cleaned off excess in one location. Thought venting was going away from screen.......evidently not!

So the battle begins........screen is off wall, fabric is on dining room table and here are my weapons of choice:






Wife being the fabric expert and have contacted Chris at Seymour-SE.........strategy for combat is prepared!

Using fabric fray glue on edges........dry time is 15-20 minutes so this will be a looooong process. Chris stated fabric will fray.......definitely an understatement!

When all edges are glued.........Will soak Dawn dish soap on stain and will let soak for 20 minutes and then wash fabric in hot water on delicate cycle. When done, will spread screen material to dry naturally. When dry, wrinkles will be clearly visable but tension from installation will eliminate any of those wrinkles.......Chris' own words!

If I loose this battle....$500+ for fabric material is literally down the drain!

Is been agreed upon, Dawn is weapon of choice.

You have another idea other than Dawn?
