Auralex vs Primacoustic ?

I'm planning to build a small studio for recording fado music (kind of blues from Portugal).
One vocal booth, another room for maximal three guitar players (acoustic), the control room and nice wood on the walls everywere.
As it will be a small studio and I want it to be somewhat "live" (I only intend to record that kind of music), I'm thinking about using acoustic foam just to get ride of nasty frequencies in problem zones.
I've found these two firms delivering acoustic foam:
Auralex Acoustics ( http://www.auralex.com/ ) and Primacoustic ( http://www.primacoustic.com/ )
Any opinions which one is better and/or cheaper?
What is your experience with both products?

Thanks in advance.

I suppose the simplest option is to compare both products with straight insulation abosorbers. The Primo products are slightly different from auralex in that their diffusors are constructed of timber (MDF) whereas auralex uses straight foam.

Here is a list of the absorption figures for the various insulation products which you can compare to the foam product figures from each site.

These packaged treatments offer the advantage of being visually appealing so no additional work is needed to install them whereas straight insulation requires cloth frames etc to make them look ok in situ. When comparing the cost you must take into account this factor because if you aren't a carpenter you'll need to hire one to make the fibreglass product work.

Hi John Sayers:

Your page

looks remarkably like mine

except that yours is out of date and is missing a few updates and additions. It does get added to as I discover new coefficients. Occasionally I fix broken web links too.

Thanks John Sayers and z60611,

I've got the info and I'm going to read it right now.
I hope I will understand all those numbers

Thanks again
