Anyway, while reading up on things at RealTraps, Auralex, RPG, and other similar sites, it seems that each company advovates treatment based on their main product (not suprisingly). I.e. RealTraps seems to emphasise absorption (esp. at bass and low mid frequencies), RPG focuses on diffusion and diffraction, and Auralex would like to sell you foam. Lots of foam.... None of them seem to advocate all three (RPG perhaps coming the closest with their trinity approach: imaging, spatial and bass managment tools). However they seem to focus on specific bass frequencies when using membrane absorbers, while Ethan seems to advocate more broadband designs. |

So, in a small room, stick with as much broadband bass trapping as you can handle, control the first reflections (as you mentioned), and then play with diffusion to taste. I also tend to agree that in smaller rooms, diffusion is not the best treatment on close surfaces. Stick with reasonable thick absorption at the critical first reflection points in smaller rooms as far as I'm concerned. Definitely have to consider the rear firing issue on dipole main speakers. I really don't care for this design, but I udnerstand there are a lot of high end loudspeakers that use this concept. I would put some absorption behind the speakers anyway (even with direct firing loudspeakers) as the diffractive reflections off the front wall will cause imaging issues in most cases.... my 10 cents... |
