Is this effective enough to treat the front wall? Advice needed.

[jimmyngouv]

Hello everyone,

I'm looking for some budget material/panel to treat the front wall. Will these be effective enough to treat the front wall (2 or 3 layers will be used) : http://www.amazon.com/gp/product/B0049VIQCK/ref=ox_ya_os_product


or this will be much better at absorbing sound:

I have little knowledge about these things. All advice are appreciated.

Jimmy,

forget about the underlamient, much better options....... http://www.atsacoustics.com/cat--DIY-Acoustic-Materials--102.html

is but one choice, but first we need to know more about your set-up and what freq you are trying to control. Lower bass freq usually benifit with 'corner traps'. Keep in mind of the corolation with freq and thickness of absorption material.

Yes, you need to know what you are trying to control. Broadband absorption? Bass room modes control? Diffusion? Any of these may be called for, but before you can decide on which, you have to have an idea of what problem you might be addressing.

You might provide some info about room, speaker placement, dimensions, etc. It would help get an idea of the issue.

Look up the GIK Acoustics site. They have a good discussion of room acoustics and offer reasonably priced panels for a variety of purposes.

I'm using a pair of Spire for fronts, a EM ESL for center, mirage nanostat for surrounds and a original dynamo for sub. I'm driving them with a Pioneer Elite 56txi for HT and a modified Heathkit 121 that has a 2 ohm output connected to a Musical Fidelity V-DAC MKII with Pangea p100 upgraded power supply for 2 ch music in a 13x13 room.

I placed the Spire about 2.8ft from the front wall and about 6.5ft apart. I read that most people use some kind of sound panel to absorb the backwave, so I'm looking for something that doesn't cost a lot of money but still effective enough.

Did you look up the link I sent you or the GIK site Guido suggested ? BTW, if you can bring your Spire's out another foot or two

Yea I just looked it up. I like their price for acoustic insulation. I guess these are much more effective than the auralex design kit? There are too many selections for the acoustic insulation. Would you please point me to the best value/performance type? I will try to bring out my Spire like you recommend. And also, should I treat the entire front wall or just 3 panels for L,R and Middle are good enough? Thanks in advance twich.

Here's a pic of my simple system:

I will move the TV more to the center and raise it higher than the EM ESL.

I had excellent results with RPG Skyline diffusers, 4 panels (2 on either side) behind my SL3s. This may seem a bit counterintuitive, but it works well for me. I have absorbing panels on the side walls at the first reflection points.

You may want to experiment with sound panel placement before deciding on where you get the most benefit. Good luck!

After much measurement and testing of absorption, diffusion, flat walls, foam (like the Auralex), the winner was absorption right behind the speakers. Use a good broadband absorbers like the larger GIK or RealTraps panels. For placing behind the speaker use a product that is not reflective, so the RealTraps HF is the only one I'd recommend for that location.

For the details on how and why I arrived at those recommendations, please read my 'Room Treatments' threads in this forum.
