[G>SUS]

hey guys, i been reading a lot here this past days or week, before posting stuffs!

i got a pretty good deal on this package for treatment, wish for what i can see is decent for a guy starting on mastering, any comments or feedback are welcome!!


RPG Diffusor Systems SIBGP0 Studio in a Box Gold Package Gray | Full Compass

[Cellotron]

Really great bang for buck off the shelf options available at GIK Acoustics. Acoustic Panels and Bass Traps. as well - highly recommended!

Best regards,

+1 on GIK and/or RealTraps.

ALWAYS start with SERIOUS broadband absorption - and lots of it. You can't overdo it and you'll probably never actually have "enough" (I have 35-ish panels in here and if I had room for another dozen, I'd probably put them in). NO foam, minimal diffusion (and NO foam) and no foam.

I just don't see tiny little 9" lightweight foam corners being anywhere near as effective as 2'x4'x4" 703 panels...

RPG make some very interesting premium products. I don't see any of them in that package. There are great articles on room treatment and setup at GIK and RealTraps and studiotips.com, and elsewhere of course, but I am familiar with those mentioned and can recommend them.
Size and quantity matter. I regularly use GIK and RealTraps and warmly recommend them. Do consider the biggest possible corner devices. Area trumps though. Floor to ceiling in all corners would be a good start.

I built my own treatments, except some golden rule diffusors. I take 2x 2" O-C 703 panels and double them together for a single 4" deep trap similar to what you can buy at GIK. The double thickness helps it get down to deeper bass regions. You can also sandwich paper between the layers for even more deep bass absorption. I also have some single thickness panels I can take with me for remote recordings. In retrospect, I should have used a combination of 705 and 705 FRK.

Why minimal diffusion?

[MASSIVE Master]

Just for starters. IME, it's difficult to get a handle on anything if the low end isn't under control. I'm not saying not to add diffusion - I'm just suggesting not to start with it.

Just checking.....We are still talking about acoustics right?

Yes - The low end in the room.

I'm sure a few of us are guilty of (or know someone that's guilty of) throwing foam up all over the walls in some room and then chasing the low end issues after.

[wado1942]

You also need a fairly large room for diffusion to be effective. You need space for the sound to scatter!

some reading doing on in !! i guess GIK is a better alternative than RPG! i goo with this product, i mean thats the core of the room and set-up.

Please replace "broadband absorber" with "bass trap".

Overdoing broadband absorption is very easy. Those are best used where they are most needed, to tame early reflections. Broadband absorbers all over the room typically leads to an overly damped response. Bass traps can typically be reflective from mids up without creating any problems with early reflections.

It does of course depend on what the goal is. Most people find that dead rooms are better than no treatment, but many prefer not to have a totally dead response.

or just go for a few of these for the back of your room

At this price point GIK no question. RPG have some extremely expensive, high performers at the far end of the price scale. Typically bought by OPM (Institutions, well funded studios, etc. using Other Peoples Money!)

Bass traps of the quarter length type are considered broadband aborbers, right?

I presume you mean porous absorbers. They are low pass filters, so highs will always be damped while the low end response depends on absorber thickness, resistance to airflow and distance from boundary. It's easy to make them reflect highs; add something dense enough at the surface. Like thick cardboard, wood panels etc. Some holes or slats may be needed to let low end through, depending on the size of the reflectors. This will make it more suitable for general use as low mid and upper bass absorbers.

Gercha. Sorry for the misunderstanding
